[8] Setting at the Time of Replacing the Display
When the display was replaced, it is necessary to make setting in accordance with the truck.

1. Setting the code

After replacement of the display, the codes 701 (Fuel specification) and 702 (Truck weight) displayed
in the serviceman mode are the set value stored in the controller.
It is necessary to cause the new display to store those set values as well.
□　Code 701: Fuel specification
□　Code 702: Truck weight

How to set: Refer to 3-[5] Controller Setting Code700

Gross outline: Cause the display to display the set value set by the controller of code 701 (Fuel
specification) and 702 (Truck weight) to cause the display to store those values. Accordingly, the
setting of display becomes the setting of controller.

CAUTION
If the setting is not made, proper value is not displayed in the Fuel Level Gauge, etc.

2. Copying the display data

□　Copy the Hour Meter time
In addition, in the case of a truck with an optional speedometer, make also a copy of travel distance
and travel hours together.
□　Copy of travel distance
□　Copy of travel hours

How to set: Refer to [Copy operation from controller to display] shown in 3-[4] Serviceman Mode.

Gross outline: There is a function that copies the Hour Meter Time (Key ON Time) that the
controller stores as a sub data in the display.
The copying of Hour Meter Time that the controller stores to the newly-installed display enables the
counting from the same Hour Meter Time until now.
Similarly, for the case of a truck with an optional speedometer, the copying of Travel distance and
Travel Hours is available.

CAUTION
・This function is not available if the display and controller are out of order.
・If this setting is not made, the hour counter of display starts to count from“0.0h”and there may
be the case where the calculation of operation management, etc. is impossible. In addition, in the
case of a truck with a speedometer, the Travel Hours and Travel distance are counted from“0.0h”
and“0.0km”respectively.
・When the readings of Hour Meter, etc. of the display to be installed are greater than the value of
the display having been removed, the data copy is not available. Error code Errd11 ｘ（x is a figure）
appears.

 3. Controller
[1] Controller Configuration
The controller of this truck is an all in one controller equipped with control functions of respective
solenoids for traveling, cargo handling, steering knob misalignment correction and display.
The controller makes judgment on the motion of respective solenoids and gets control over a part of
display indication according to a variety of input commands and input conditions.
The display is also equipped with CPU and performs a variety of data communication with the
controller. Further, the controller carries out the computation and storage of daily simplified driving
data as well.
Though the driving of a truck is available even if the communication between the controller and display
goes dead or the display goes out of order, the selection and setting of functions, simplified driving
control, speedometer display, Load Meter display, etc. become not available (Some of explanation
above are for the optional function).

[2] Exposition of Basic Controller Operation
Communication between controller and display
As both controller and display are equipped with CPU and the communication of the mode setting,
hour meter, (speed and travel distance) and adjusted value data is performed.
As 7-segment character is used on the adjustment screen of display, slightly unreadable word and
abbreviated characters are used.

Hour, Speed, Travel Distance, Travel Hours data management

Key Switch ON Time (hour meter) is totalized by the display and the travel distance and travel hours
and speed indication are calculated by the controller and the results of such calculation are sent to
the display for indication. (Key Switch ON Time is stored by the display as a main data and the travel
distance and travel hours are stored by the controller as a main data. In addition, both display and
controller store each other's main data as a sub data. Therefore, the copying of each other's data is
available at the time of respective replacement.)

Anti-restart control
Even if you manipulate the starter to run by turning the key switch from “ON” and try to
manipulate the starter to run again after the key switch returned to the “ON”position, the starter
does not turn.
In this case, return the key switch to the “OFF” position once and then put it to the “ON” position
to allow the starter to run.

Orbitrol knob misalignment correction control

When the knob position of steering becomes misaligned by comparison of steering angle and trail
angle, cause the knob misalignment correction solenoid to operate to correct the misalignment of
knob.
In terms of structure, there may be a case where the lag of the order of ±35°arises.

Restriction on Valves for Traveling (This is not a brake function)

This is a function that works when the operator has left the seat.
In the case of automatic transmission (AT) truck
If the operator leaves the seat for 3 seconds or more continuously with the shift lever put in the
Forward or Reverse position, this function causes the truck to stop traveling. (However, coasting
may occur on the sloping road)
When the shift lever is put in the Forward or Reverse position and the operator has left the seat for
3 seconds or more continuously, this function turns off the solenoids for traveling.
For the cancelation of this restriction, the operator must put the Forward/Reverse shift lever to the
neutral position once after taking the seat.
Return to Neutral function (Standard function)
In addition, after the restriction on the valves for traveling has applied, even though the operator

3-9
 returned the seat, traveling is not available immediately. Return the shift lever to the Neutral
position once and then manipulate the Forward/Reverse shift lever to allow traveling.
When this function works, a warning appears on the display.

In case of foot directional control (CT) truck

Turn off the solenoid for travel, continuously more than 3 second after the operator left the seat
during the direction control switch is in Forward/Reverse either position.
If the operator return to the seat (seat switch ON), immediately makes travel solenoid ON and be
able to travel (drive).
In addition, as for the foot directional control (CT) vehicle, the Forward/Reverse valves turned OFF
automatically if operate the parking brake.
When this functions work, indicates the warning on the display.
Travel valve restriction will be canceled by the operator seated.

In the case of manual transmission (MT) truck

If the operator has left the seat for 3 seconds or more continuously, buzzer alarm is emitted.
When this function works, a warning appears on the display.

This warning is reset when the operator sits on the seat.

CAUTION
Since the traveling is not locked, the truck coasts on the sloping road.

Restriction on Cargo Handling Valves (optional)

This is a function that works when the operator has left the seat.
If the operator left the seat for 3 seconds (standard value) or more, this function stops the cargo
handling operations such as lifting, tilting, attachment, etc. forcedly. Due to this function, cargo
handling operations such as lifting/lowering of mast, forward/backward tilting get impossible.
When this function works, a warning appears on the display.
Cancelation of restriction on cargo handling valve is performed when the operator sits on the seat.

Headlight Reminder Warning

If the key switch is put in the “OFF” position with the headlight lighted, a headlight reminder
warning tone is issued. This function calls operator’s attention to turn OFF the headlight for the
protection of battery at stop.
For your information, no message or alarm appears on the display. A headlight reminder alarm is a
continuous tone for 2 seconds and subsequently intermittent tone is issued twice.
As this warning pattern is repeated, this warning is distinguished from other warning tone. You can
check the meaning of this warning from the warning tone.
Resetting of a headlight reminder alarm requires turning OFF the headlight switch or putting the key
switch in the “ON” position.

3-10
Speedometer Display (Priority selection of clock, speedometer and load meter is available. Refer to the
section“Operator function”)
Simultaneously with the start of traveling, the speed is displayed on the display. Real time clock is
displayed while the truck stops. The travel distance is calculated and displayed on the display.

Display and Storage of Operation Management Data (Refer to the section“Operation Management
Check”)
Daily operation (key ON, travel hours and travel distance) is stored for the past 10 days (including
current day) together with the calendar.

Simplified Truck Driving Management Data

Simplified operation management data is stored for the purpose of truck management and to get a
grasp of operational status.
1) Cumulative data
2) Today's data
3) Display of the past 9 days of data by item ordered by date

CAUTION
1 When the battery was removed, and when the time of real time clock does not stay in
adjustment, make the setting of time of the clock.
2 As each data is stored and updated when the key switch is turned OFF, if the battery is
disconnected directly, there is a possibility that the stored data will go wrong.
Further, in such a case, the calendar will be reset. When the calendar was reset, the date is
displayed as E1, E2. (Date is displayed as a count value from the day when the date was reset).
3 If the date and clock go wrong, the operation management data will not coincide with actual
working hours.
(Because the change of date will not coincide with actual clock)
4 The day without operation = Day without no change in data is not counted and not displayed.
5 There may be a case where 0.0h is displayed even though the operation was performed.
(If the operation does not exceed 0.1 hour, 0.0h is displayed).
6 In terms of display structure of the display, check becomes item-by-item one. Batch display by
means of display is not available.

Switch Monitor
When the setting of Switch Monitor Condition is made under serviceman mode for the investigation
about motion failure, operational status of each switch (ON or OFF) is sent from the controller to the
display.
This is a function to facilitate the localization of the defective point by operating the truck while
checking each input and output state.
Traveling under monitor condition is also available.

3-11
Variety of error displays and history
Error display
When an error occurs in the controller or display, the error information is collected by the controller
once and then the controller sends it to the display.
At that time, the controller displays the warning “!” mark and controller error “ErrC” + Error
Number, Display error “Errd” + error number on the display according to the types of error.

Error history
When an error occurred, its record is preserved in the controller. Check on such data under
servicemen mode is available. Error check includes following two types:
①Latest error display of up to 10 error in the case of controller and 5 cases in the case of display
can be made together with the date and hour meter readings.
This is a system to display the date when an error occurred together with hour meter readings.
Errors are stored in the controller up to 10 cases and in the display up to 5 cases.
(As a matter of convenience in display form, it is necessary to check the error history memory one
by one in sequence)
Refer to the section “Error display”
②Error occurred in the past is displayed in bit (0.1).

Key Switch“OFF”Reminder, Battery Dead Alarm,

If the seat switch stays ON with the key switch remained ON without starting an engine for some
reason, two or more valves stay operating. If this condition remains unchanged for a while, there is a
possibility that the battery will go dead.

　● In the case where the seat switch stays ON with the key switch remained ON without starting an
　　engine
Conditions such as the operator remains sat on the seat, something is left on the seat or the seat
switch remains ON for some reason. This is a function to issue an alarm under such conditions.

pressure, its accuracy varies depending on the conditions. Use this value as a reference of load value.
In the case of basic setting, when you push M button with the truck stopped, load meter display
appears.

Parking / Leaving seat warning function

If the operator leaves the seat with the key switch remained “OFF” without pulling the parking lever,
an alarm is issued.
When you put the key switch in the “OFF” position, this is a function to issue an alarm with buzzer
tone for 6 seconds (Standard value) to promote awareness if the operator left the seat with parking
brake released.
Cancelation of alarm is performed when the operator sits on the seat or the operator pulls the parking
brake.

Speed Alarm Function (Some functions are maker option)

・This function causes the buzzer in the display to sound when the truck exceeds the arbitrary speed
and displays the symbol giving a warning against speed over. (This function uses the standard
display).
Speed alarm display and a warning tone will be cancelled automatically when the truck slows down
to the arbitrary speed or less.
・Speed alarm is output to the outside when the truck exceeds arbitrary speed. (Maker option)
External output of speed alarm is stopped automatically when the truck slows down to the arbitrary
speed or less.
Speed alarm is settable at 2 truck speeds. Speed alarm 1 & speed alarm 2. Speed alarm setting
requires the addition such as harness, external output (lamp, buzzer, etc.) and installation stay and
setting of controller.

 [4] Serviceman Mode
Serviceman mode: Serviceman mode is a function to be used for making the setting of controller and error check, etc.
First, the display indication is performed by the indicator with scarce information amount and expression power. Therefore, though few in numbers, the mode of
expression being unlikely as a word or abbreviated character is used. As the display indication is dependent on the display function, please understand this point.
When checking each data through the display, check and setting shall be made through the item-by-item display of data put in position in the matrix form. It is
very difficult to understand the configuration of matrix in your head. When you use the serviceman mode, always keep the material including troubleshooting
handy and you are requested to conduct assured operation checking the material.

How to get into the serviceman mode

　First, put the key switch in the “OFF” position. Turn “ON” the key switch while holding 3 display change buttons ◁,▷ and M down. When said buttons are
continued to be held down as they stand for 2 seconds or more, the serviceman mode starts with starting tone. (Serviceman setting mode becomes adjustable). When
exiting from the serviceman modes, put the key switch in the “OFF” position once, wait for 2 seconds or more and then put the key switch in the “ON” position.
Through these manipulations, the mode shifts to the normal display mode.

[7] Error History and History Memory
In the serviceman mode, check of error history and error memory is available. This function is usable as
a tool when a failure occurred in the controller. (Machine related failure is not included).

How to use this function:：

Error is displayed on the truck display. Or where there is a point displayed, check the occurrence of
error.

A:Error history On the screen the controller stores 10 errors in the past with error code number and
occurrence date in sequence from the latest and display stores 5 errors.
For the meaning of error code, check with Error History Memory List.
B:In the error history memory, both controller and display show the error occurred up to now in bit. If
the bit corresponding to each error is 0, such error did not occur. 1 means that error occurred.
For the description of error item corresponding to each bit, refer to the error history memory list.
C:Identify the cause of error from the error code and error bit.
D:When the cause of error has been identified to an extent, identify the cause of error occurred by the
use of troubleshooting and switch monitor to modify the defective point.
E:Once the cause of error has been removed, an error will not occur.
F:After checking an error, in preparation for the next occurrence of error, clearing of error history
facilitates the next check. For the clearing of error history memory, refer to the section“Memory
clear”.

Maintenance
【Checking the error number, date when an error occurred, Hour Meter readings when an error
occurred of controller】
As up to 10 error numbers, dates when an error occurred and Hour Meter readings when an error
occurred of controller are stored, they are effective for the failure analysis of controller.

[9] Switch Monitor
With a selection of switch monitor under serviceman mode, check on the input status of display and
controller is available.
This function is usable as a tool when the failure occurs in the controller. (Machine-related failure is not
included).
Switch monitor
This function causes the I/O signals of the controller and display unit to de displayed on the display,
monitors the status of each switch and enables the check whether switches are normal or not.

How to use this function:

This function is usable to check the error when the error display is displayed on the truck display or there
was an indication being displayed.
Ａ：Make an estimate of error point from the error code in the error history by means of
troubleshooting.
Analog input: Variation of sensor can be checked.
Digital input: Check can be made whether the signal from each external unit has been input or not.
For the type of analog and digital input values, refer to the following sections.
Ｂ：ogether with the check of respective parts through the wiring check, equipment check or tester
check, it is possible to check the input to the actual controller by the use of switch monitor of
controller.
Ｃ：When there is no problem in the external wiring, equipment, this function is also usable for the
failure judgment of controller itself by the use of switch monitor and forced output function of the
controller.

CAUTION:
Use the forced output after the check of truck condition. Though the judgment of short-circuited
or break is made by the controller, first carry out this function after the check of external wiring,
equipment, etc. If external wiring or equipment has a problem, it can lead to the breakage of truck
and controller.

 [10] Storing the Trail Center Position
【Store the center position of trail when Steering Knob Misalignment Function is provided】
Adjust the steering to the condition under which the truck can travel straightforward
independently of steering knob position. Carry out the following operations under this condition to let
store the trail center position. Then, remove the steering and mount it again adjusting the knob position.
※　Not let store the steering position, let store the position of trail tire.

How to set
1 Drive the truck to adjust so that the trail is situated at the center (where the truck goes straight
ahead). At this moment, it is OK even if the handle is not present at fixed position.
2 Store the trail center position by the operation to store the setting.
3 After storage, remove the steering, adjust the steering sensor to the center, line up the positioning
3-point claw of steering with positioning 3-point groove of steering sensor to mount.
4 Manipulate the steering for a while to make sure that the steering returns to the specified steering
position.
5 When steering falls within specified position, tighten the steering nut to complete. If steering does
not fall within the specified position, carry out the steps from 1 again.

[11] Memory Clear
It is possible to clear the data including error history, truck management data, maintenance information
stored in the controller. Select the Memory clear on the screen of display in accordance with the
following.

How to use this function：

・Error memory, history reset
After investigation of truck error and writing down the error data separately, have the data reset, it
is easy to check the error at next investigation. However, if you hope to leave over the data to use
such data in the next time as well, there is nothing wrong with leaving over the data.
There is a case where we cause the error to occur frequently not with any intent at the time of
trouble investigation. As such error history as well remains, there is a possibility that it will be
mistaken at the next trouble investigation. In such a case, it is better to have reset.
Where the controller removed from other truck is used through replacement for some reason,
always reset the error history. If the data of different truck remains, it can be mistaken at the time
of next trouble investigation.
・Operation management data reset
(Including simplified LTV data reset as well)
Where the controller removed from other truck is used through replacement for some reason,
always reset the operation management data. If the data of different truck remains, it can be
mistaken at the time of data check.
・Maintenance Data Reset
Where the controller removed from other truck is used through replacement for some reason,
always reset the maintenance information data. If the data of different truck remains, it can be
mistaken at the time of data check.

[13] Simplified Load Meter (Maker Option)
Load meter display is an optional display function.
Rough load value can be measured.

CAUTION
● This is not an officially-certified load meter. Use the load value as a reference value tenaciously.
● As the mast pressure varies due to the inclination of mast, engine R.P.M., opening condition of
valve, running on the step while traveling, etc., there may be a case where the load value varies on
a measurement-by-measurement basis. When measurement is made at mast relief, the load value
becomes completely different.
● At the occasion of using this function, option setting and“0kg set”is required in advance.

Setting
Check that Option 2- (3 bit) is effective. If it is not set (1), set it. Further, check that the Option 2- (2 bit)
which determines Display/Not display the measured value of load meter has been set.

　How to use the simplified load meter

This is a load meter to measure the estimated load. There is an error to the extent of several
percentages to several tens of percentage under defined condition. (※ 1. Variation exists depending on
the condition). Minimum measured load is 40kg (Less than 40kg is displayed as “0kg”). This function
converts the mast pressure into the load to display it on the display. Valid/Invalid of load meter is
selectable by pushing M button at the side of display. By turning the key switch “OFF” you can leave
from load measurement mode. Put the cargo on the fork and cause the fork to lift by about 30cm
from the floor. After several seconds, load measurement is displayed (※2). When the mast load varies
by 50kg or more, the load measurement is started.

　Mode Change between ordinary display and load measurement mode: Refer to the manipulation
image and example of display
・Ordinary display: After a short time from turning “ON” the key switch, Real Time Clock is
displayed.
・Ordinary display: In the case of with speedometer. When the truck starts to travel, the speedometer
display is indicated.
・When the load meter is selected, the display changes to Load Meter by pushing M button on the
lower right of display.
・By turning OFF the key switch, the initial condition returns. When the key switch is turned “ON”
next time, ordinary display returns. When you hope to measure the load again, manipulate the M
button.

　How to measure the load
１Have the object subject to measurement put on the center of pallet, etc. as much as possible.
２Scoop the pallet with fork so that the fork can enter in the pallet up to its root.
３Put the tilt angle to the perpendicular (※3) and lift the pallet from 30 to 40cm from the floor by the
accelerator manipulation (※4) to the extent that the cargo is lifted. When measurement is started,
“LoAD” is displayed.
４Ease up on the accelerator and wait for several seconds (※5) in idling.
５The load is displayed together with beep. Upon completion of measurement, “**** kg” is
displayed. (※6). Use the display of this time as a guide (※1)
６When measurement is made again, lower the cargo to the floor once and carry out the step 3 again (

There are 3 display types for the load meter by means of code 726. Select it according to the request.
　Initial value and recommendation are code 726 setting (1).

Set value Description

Convert the input value of mast pressure into the load. Equalize said value to
display it.
0
The load continues to vary with a change in the most pressure. Therefore,
the accuracy of load measurement is not so good.
When there is a change in the mast pressure (where there is a pressurization
and depressurization width), convert the input value of mast pressure into
1 the load. Equalize said value to display it. Load value after a constant time
Code 726 from the time when the mast pressure stabilizes to an extent is displayed
fixedly.
Load measurement pattern Fixed type (somewhat good accuracy compared
with 0 and 1). After the detection of the condition that the mast pressure
was lowered once, convert the input value of most pressure into the
2 load. By lifting up the mast after the mast was lowered completely once,
measurement pattern is fixed and its value is equalized to display it. Load
value after a constant time from the time when the mast pressure stabilizes
to an extent is displayed fixedly.

3-62
 CAUTION
This function is a simplified load meter that measures the load by putting a cargo on a pallet, etc.
Never attempt to measure the body weight by putting a person on the fork as it is dangerous.

※１For the load, the mast pressure is converted into the load. Therefore, the error from several
percentages to several tens of percentage occurs depending on the load center of cargo, the way
of putting the cargo on the fork, tilt angle, engine and lift manipulation.
※２Too much lifting up of mast results in the deterioration of accuracy in the load measurement.
Make measurement under the condition that the cargo is lifted up by 30 to 40cm from the floor as
a guide.
※３If the tilt angle is not perpendicular, the accuracy in the load measurement diminishes. Start the
measurement after making the mast perpendicular as much as possible. In addition, the measuring
method to make the mast perpendicular after measurement can not attain good accuracy.
※４Too much stepping on the accelerator results in the deterioration of accuracy.
※５The load is displayed after several seconds from the time when the fluctuation of mast pressure
subsided and the load data stabilized. Standard setting is displayed 5 seconds after the data
stabilized.
※６Upon completion of measurement, its value is fixed. Therefore, even though the cargo is added
after completion of measurement, the load value is not added. When the cargo was added, make
measurement again.
※７For securing the measuring accuracy to an extent, make measurement while maintaining the
height from the floor constant. (Even if the lift is manipulated again, when there is a change in
the mast pressure of 50kg or more, remeasurement is started but the accuracy does not stabilize.)
※８If the truck travels after measurement, the speed display appears once, however, when traveling
stops, load meter display returns. Load measurement while traveling is not available.
※９If there is a change in the mast pressure of 50kg or more as a converted value into the load,
measurement starts. “LoAd” is displayed and measurement starts. As the condition while
“LoAd” is displayed represents the condition that the stabilization of load data is waited, if
cargo handling operation and increase/decrease of engine R.P.M. are performed under this
condition, the load measurement may take time or the load accuracy may bastardize extremely.

3-63
 CAUTION
There may be a case where the measurement is started with the manner of operation other the
fixed one and the load is displayed. In the case of unusual operation, there may be a case where a
big error occurred. When a certain degree of data accuracy is requested, make measurement with
a fixed measuring method again.
When the fork is replaced, the attachment is mounted or replaced,“0kg”setting becomes
necessary. When replacing or retrofitting the fork or attachment, contact with the maker.
When the load is 40kg or less after the start of measurement and completion of measurement, it is
displayed as“0kg”. Low load cannot be measured.
Load measurement such as a cargo was added once the measurement completed is impossible.
However, depending on the conditions, measurement may be started, there may be a case where
the accuracy drops extremely.
When making the load measurement, make measurement after selection of load display. Switching
of load meter at some midpoint of cargo handling operation (manipulation of M button) may result
in poor load accuracy. (If the measurement mode is put while the cargo handling, or immediately
after the cargo handling, there may a case where the load with a big error is displayed. Make
measurement after the truck stabilized).

3-64
[14] Load Meter 0kg Set
Serviceman mode
【Load meter manual“0kg”adjustment】(Basically, use automatic 0kg adjustment)
This function causes the timing to store as 0kg to be stored manually. This is a mode that the
serviceman specifies the measurement timing. As the mast pressure is used, the pressure varies as time
advances. This function causes the mast pressure value corresponding to 0kg to be stored while watching
the actual changing condition.

１Have the mast made perpendicular and fork lowered to the floor with engine stayed “ON”
. (Inclined mast makes the error bigger. When certain degree of accuracy is required, it is
recommended to adjust the “0kg” with 90°±0.1°as a guide and make measurement with 90°±
0.1°as a guide as well.)

２Have SET screen invoked in advance and lift up the fork of the order of 30 to 40cm from the floor.

３Cause the value to be stored at adequate timing while watching A/D value.
This value is stored as “0kg”.

４Push M button to exit from the setting.

５Try to measure the load. (Refer to the section “Load meter”).

 CAUTION
As a final check, it is necessary to use the basic load (For example 500kg) as a load, measure it
with this load meter to make fine adjustment of error by the use of code 738.
Select the corrected value from the value to be displayed on the load meter at this moment. For
example, when the display is made as 530kg, the corrected value is 500 / 530 = 0.94
For example, when the display is made as 465kg, 500/475 = 1.05
Serviceman code: Select code 738, 094 or 105 from code setting to make adjustment.
When performing load meter 0kg set or load measurement, for the purpose of making stabilized
measurement, use the truck keeping the hydraulic fluid temperature at around 45° .
When the hydraulic fluid temperature is low or it is extremely high, measuring accuracy may be
poor or repeated measurement may not stabilize.

Operator mode, serviceman mode
【Load meter automatic“0kg”adjustment】
This function judges the mast pressure value that hopes to make it as 0kg to cause it to be stored. This
is a mode where the controller determines the timing to make measurement automatically. As the mast
pressure is used, the pressure varies as time advances. This function causes the mast pressure value
corresponding to 0kg to be stored watching the actual changing condition.

１Start an engine and make the mast perpendicular with the fork and attachment to be used actually
mounted. (Inclined mast makes the error bigger. When certain degree of accuracy is required, it is
recommended to adjust “0kg” with 90°±0.1°as a guide and make measurement with 90°±0.1
°as a guide as well.)

２With a push of
△

button, load “0kg” set mode begins. The value to be displayed this time is the
value set as “0kg” previously.

３With a push of
△

button again, data for ”0kg”, that is to say the mast pressure reading starts.

４Rev up the engine R.P.M. to the extent of lifting up the cargo actually in the work. Keep the engine
R.P.M. as that time.

５Lift up the cargo with 30 to 50cm from the floor as a guide. (actual work procedure)

６After waiting for several minutes, ‘Lo 0’ kg is displayed and “0kg” set completed.
Reference of load meter: ××× value is a raw reading of AD. It is displayed with HEX (hexadecimal

[15] Overload Alarm (Maker Option)
This is a function to issue an alarm when the load reaches specified load value or more. (Usable
only when the truck with mast pressure gauge).
There are 2 types as overload alarm.

CAUTION
As the overload measurement is based on the mast pressure value for load meter, there is an
error of several percentages to several tens percentages. As the mast pressure varies due to the
inclination of mast, engine R.P.M., opening condition of valve, running on the step while traveling,
etc., there may be a case where the alarm is issued or not issued where the load is at the bare
overload setting. When the load reaches the relief pressure, there may be a case where the alarm
operation does not stabilize due to unstable mast pressure. In the case of relief condition, the alarm
continues to be issued.

Type using standard display

１．It is possible to issue the alarm by the use of function and buzzer of standard display according to
the option setting. Overload alarm display and buzzer operation become effective on the display
according to the option setting.

Setting check

[17] Speed Limit (Electronic controlled GAS/LPG engine) (Maker option)
This is a speed limit function of the electronic controlled GAS/LPG engine vehicle to be used when
hoping to place a limit on the maximum speed.
Making the setting of speed limit option and speed limit speed enables the speed limit.

Features and precautions in terms of vehicle

The speed limit device performs the operation to control the maximum speed, however, its effect
on the speed may appear depending on the road surface condition and vehicle situation. This is
not a device that allows the vehicle to continue to run always without error in the set speed.
The time required for the vehicle to reach the speed limit speed varies depending on the applied
load and road surface condition (hill-climbing angle).
There may be a case where the vehicle does not reach the speed limit speed depending on the
applied load and road surface condition (hill-climbing angle).
There may be a case where the vehicle reaches the speed more than speed limit speed due to the
applied load and road surface condition (downhill).
In the case where the vehicle runs straight-ahead after turning run, there may be a case where the
vehicle reaches the speed more than speed limit speed.
When the set speed for the speed limit is low, there may be a case where the acceleration in
turning is higher than acceleration in straight-ahead. (In the case of setting when the customized-
specification speed limit is 8km/h or less).
When the vehicle runs with high engine speed due to the cargo handling operation, simultaneous
operation, etc., there may be a case where the vehicle reaches the speed more than limit speed.

Cautions in the speed limit specification

In the case of vehicle with speed limit, we make it a rule to run at the speed actually lower than
the set speed by about 5% taking the shade of meaning of the speed limit into account.
If the vehicle setting codes 700 through 704 and 706 do not coincide with vehicle, the difference
may develop between speed limit speed and actual speed. Don’t try to throw the settings
of codes 700 through 704 and 706 into disorder including check operation intentionally as it is
dangerous. Such attempt leads to the malfunction of engine, controller breakage, and faulty
operation of speed limit and malfunction of respective devices.

Cautions in the speed limit customized specification

In the case of customized specification with the degree of speed limit setting other than 8km/
h to 20km/h, codes 707 and 708 are displayed as“ - - -“. In this case, if the change was made
to the setting of the codes 707 and 708,　return to the customized specification gets impossible.
Please take note that the adjustment to the degree of setting will be limited to the range from
standard 8km/h to 15km/h and 8km/h to 20km/h. When the setting was changed, replacement
of controller and resetting of controller will become required and adjustment cost accrues.
(Customized speed limit setting controller).
Customized speed limit setting controller: Always specify the speed limit speed [set km/h] at
arrangement.

without careful consideration. Customized specification: Speed limit speeds are 7km/h, 21km/h,
etc.

Speed limit speed correction

In the case of vehicle equipped with speed limit, we make it a rule to run at the speed actually lower
than the set speed by about 5% taking the shade of meaning of the speed limit into account.
It is possible to correct the speed limit speed when a variation in speed occurs against the actual
measurement of vehicle (worn-out tire).

CAUTIONS
Decide on the factor after actual speed was checked. Selection of proper correction value may
result in slower or faster than actual speed. You are recommended not to change the set value if
the quantity of error is a little. For the setting in the direction of speed-up (more than 100), carry
out said setting upon ample studies.

Normally, the value indicated on the speed meter is higher than actual measurement. (Taking the
safety into account, if the speed indication is higher than actual measurement, don’t change the
setting).

　３，Turn ON the key while holding the fork horizontal stop button of tilt lever down.
　　　When the fork horizontal stop button is continued to be pushed for 10 seconds without change,
　　　buzzer tone sounds and storage of horizontal position completed.

ADVICE
There is nothing wrong with not starting an engine

　４，Turn OFF the key once.

　５，Turn ON the key again, start an engine and check the fork horizontal operation.
　６，When the fork does not stop at intended position, store the stop position from 1 again.。

CAUTION
Stop position may deviate slightly due to with/without load and tilt speed.
Fork horizontal stop device is a device to stop the fork at prestored position and does not mean
that the fork stops in the horizontal position relative to the road or the fork stops at the horizontal
position relative to the truck.
When the fork stop position is stored as a horizontal position relative to the ground,
　　　　　　　　　　　: The fork stops at the position close to horizontal relative to the ground.
When the fork stop position is stored as a horizontal position relative to the truck
　　　　　　　　　　　：The fork stops at the position close to horizontal relative to the truck.

button is pushed, carry forward the code

number to the one that you hope to set.
Once the selection of code number that you hope to set completed, with a push of display change
△

button, the setting code is determined.

After determination of setting code, with a push of display change
△

button, the set value of each

code varies.
Repeated manipulation of display change buttons causes the initial screen to return.
As the set value varies in the addition direction only, when passed over the target value once, continue
to manipulate the button until such value is displayed next.
For the set value, the step width varies depending on the adjustment item.

If the set value is not yet stored, when the value that you should set becomes unknown, etc., the value
returns to the before-manipulation value.

2 action function when unclamping is operated
This is a function to prevent luggage being dropped, when the mini lever is touched without intending
it.
When the attachment is unclamped (opened), the unclamping operation becomes possible by pushing 2
action button once.

Note
Optional funtion OPT5 setting of V-ECU controller is necessary to enable E-HYD, after the
installation of Mini lever with 2 action button.

Operation explanation:
The unclamping operation must be started within four seconds after 2 action button is pushed.
The unclamping operation is possible until the lever is returned to a neutral position.
2 action function returns effectively when the lever returns to a neutral position.
Even if the lever is operated as long as 2 action button is not pushed again, the unclamping operation
cannot be done.

 4. Troubleshooting
[1] Troubleshooting procedure
The basic premise is to gain an understanding of phenomena of trouble. After understanding of them,
the indication of display screen becomes effective.

　The indications to become effective include the error code, switch monitor and error history.
　Normally, as a condition of indication on the display screen in the event of breakdown, the 　　　　
　followings are assumed:
Ⅰ．The display does not indicate at all. (Or abnormal indication)
Ⅱ．Indication of display does not conform to the truck specification.
Ⅲ．he truck travels and performs the cargo handling even through the operator has left his seat.
Ⅳ．The indication on the display is normal (There is no indication of error code, but there is 　　　　
　　something wrong with the truck)
Ⅴ．Error code appears on the display.

　From here on, the troubleshooting flowchart is shown based on the above. Further, most errors can
　be reset by resetting the key switch, when there is no reproducibility of malfunction, check the 　　
　error history to perform the troubleshooting according to the appropriate error message.
