3. Functional requirements for

outputs

3.1 General
The function of the seat safety switch is a prereq-
uisite for all outputs. In other words, no function
can be activated unless the operator sits on the
seat.
Forwarders safety switch is on the seat. Harvest-
er safety switches are on the doors. See more de-
tailed instructions in the basic machine manual.
When using the boom controls, articulated
frame steering stick or the accelerator pedal, it is
possible to stand up for a moment and the func-
tion will not be interrupted, but when engaging
a function the operator must always be seated.

3.2 Function of driving power trans-

mission

3.2.1 Displacements and control currents

of drive pump and motor control

A Function
TMC! adjusts the angles of the transmission
pump and the hydraulic motor on the basis of in-
formation from the controls and on the basis of
the load.

Workshop Manual Timberjack TMC!

Page Issue
3-2 12/02-01

B Requirements
- After releasing the parking brake the driving
direction selector must be shifted into neutral
for a brief moment and, similarly, the acceler-
ator pedal must be released to the upper posi-
tion (dead zone).
- The stairs are up.
- The high or low gear is engaged.
- The engine is running (oil pressure).
- There are no alarms activated that would pre-
vent driving.
The machine speed and the pump and motor
control current will change in relation to the
position of the accelerator pedal.
The motor current will start increasing from the
zero level the moment the machine starts moving.

3.2.2 Engine speed control

A Function
The position of the fuel injection pump is con-
trolled by means of a servocontrol (up/down).
Feedback data (Inj.Pos) will be given of the in-
jection pump position. The function below de-
scribes the interdependency between the engine
revolutions (corresponds to the position of the
injection pump) and accelerator position.

Working/ Inching

Pedal position (%) = The position of the acce-

leration pedal.
Engine rpm = The engine speed
Working = The engine working rpm
Inching = The engine constant speed
Basic = The normal engine speed
Dead band = The point where the dead zone
ends and the function is engaged.
B Requirements
For cold-weather starting purposes the position
of the servomotor is in relation to the position of
the accelerator pedal (as indicated in the illustra-
tion).
The output controls a valve opening the LS line
directly into the tank, so that the working pres-
sure cannot go up.

3.2.3 High/Low gear

A Function
The high gear is engaged by the high gear output.
Similarly, the low gear is engaged by the low
gear output.
When shifting the pump receives short impulses
back and forth for five seconds. This is to ensure
that the shifting process is successful. Driving is
prevented until the gear engagement is detected
by the gear control switch.

B Requirements
- The low gear goes on as the machine is
switched on.
- The high/low gear shifting is possible in case
the parking brake is released, the service
brake is engaged and the driving direction se-
lector is in neutral.
- To switch between a low and high gear:
- forwarders: use the hare button on the
right hand side arm-rest.
- harvesters: by the dashboard switch.

3.2.4 Service brake

A Function
The service brake is engaged by the output.

B Requirements
The output will be activated if the following re-
quirements are met:
- The parking brake is disengaged.
- If the machine comes to a halt within one sec-
ond after the pump current of the driving
power transmission has dropped below the
minimum current level.
- The power transmission stands still, the ma-
chine does not move.

3.2.5 Release of rear-wheel drive (forward-

ers) or front-wheel drive (harvesters)

A Function
If the output is activated the rear-wheel drive of
the forwarder and the front-wheel drive of the
harvester will be released.

B Requirements
The output will be activated if:
- The high gear has been engaged and the rear-
wheel drive (front-wheel drive) switch is not
pressed.
The output will be deactivated if:
- The low gear has been engaged or the rear-
wheel drive (front-wheel drive) switch is
pressed.

A Function
The front axle differential lock is engaged by the
output.

B Requirements
The output will be activated if:
- The machine does not move and the differen-
tial lock switch is pressed.
The output will be deactivated if:
- The machine does not move (the service
brake will be engaged within a second) and
the differential lock switch is not pressed.
If the differential lock switch is pressed during
driving the machine will stop automatically and
the lock will be engaged. After this, the driving
speed can be regained (Harvesters).
