 Daily inspection of the machine
Walk-around inspection

Every operator should take a few minutes to inspect

the machine before every shift.
• Inspect the following areas for leaks: axles, transmission,
hydraulic tank, hoses, tubes, plugs, couplings and fittings.
• Inspect the tires for damage and proper inflation.
• Inspect the bucket and the linkage for damage or
excessive wear.
• Check transmission and hydraulic levels
• Check engine oil level
• Inspect the cooling system for any leaks or faulty hoses,
and remove any debris from the radiator
• Check pre-cleaner
• Grease the front linkage.

4
Checking transmission and hydraulic oil levels
The sight glass for the
transmission oil level is
located on the front of the
transfer case. It can be seen
from the left side of the
machine. The indicator
should be within the warm
idle marks on the sight glass
when the machine is at
warm idle. It should be
within the cold start marks
when the machine has been off.

The hydraulic tank is

located on the right side of
the machine. Oil check must
occur when the machine is
cold. The indicator should
be between the “add cold”
and “full cold” marks.

5
 Daily inspection of the machine
Checking engine oil level and
battery disconnect

By opening the right side service door you can quickly

perform the following inspections:
• Engine oil level check by pulling the dipstick.
• Battery disconnect switch (950G II, 962G II and 980G II).
The battery disconnect switch on 966G II and 972G II
is located inside the left side service door.

Checking engine coolant level
Check the coolant level sight
gauge. Fluid must be visible.
Also inspect the radiator for
any leaks or faulty hoses,
and remove any debris from it
by opening the metal plate
with a Cat ignition key.
®

Checking precleaner
If dirt and debris is visible
through the glass, remove
the bowl and clean.
• 950G and 962G II:
If debris is visible through
the glass, remove the blow
and clean.
• 966G, 972G, 980G II:
Precleaner does not need any
particular inspection.
It is equipped with dust

Positioning of the seat is important on any machine.

The Command Control Steering makes a comfortable
positioning of the seat very important. So, take the time
to adjust it when you enter the cab.
The seat can be adjusted in 6 ways:
1 You can raise or lower the seat
2 You can adjust the seat cushion to the desired angle by
pulling the seat forward and up/downward
3 You can move the seat forward and backward
4 You can adjust the angle of the left armrest
5 You can adjust the backrest cushion to the desired angle
6 You can adjust the support of the lower back

To make your working day comfortable and productive,

it is important to well adjust the Command Control Steering.
1 You can tilt the steering column
2 You can telescope it
Once you have positioned the Command Control Steering,
test the position by turning full left and right.
After you get used to the controls, try to fine tune the position
of the armrest and steering wheel. Small adjustments can
result in big improvements in comfort.

 Starting the engine
Levers position

• The battery disconnect switch must be on.

• Make sure that the Direction Switch is in neutral (1);
if not, the machine will not start.
• Make sure that the implement levers (2) are in central
position; if not, the implement functions will not work.
If they do not work put them back in the central position
and restart the machine. Do not touch the implement levers
when starting the machine.
• When turning the ignition key, turn the key to the first
position and allow the control panel to perform diagnostics
(gauge sweep and warming indicator test) before turning
the key to the start position.
• To protect the engine from cold start wear, the Electronic
Control System (ECS) will keep engine rpm at idle until
proper engine oil pressure is achieved. Depressing the
accelerator before proper engine oil pressure is achieved
will not have any effect on the engine or engine rpm.
Additionally, hydraulic control response will be delayed
until engine oil and hydraulic pressure are at appropriate
levels.

Starting the machine
Testing the supplement steering
You can test the
supplemental steering
system at any time by
pressing the switch (1).
Note that a 3-second
self test will take place 1
at each start up.

 Command control steering
CCS Controls
The Command Control Steering replaces the traditional
steering wheel.
• A ±70˚ rotation is enough to
fully articulate the machine.
• Transmission controls are
integrated in the Command 2
Control Steering, allowing 1
you to select Forward,
Neutral or Reverse (2).
You can manually up-shift
or downshift with the
yellow switch (1) located on top of the stick.

16
A few tips
Command Control steering and Electro-Hydraulic bucket/
work tools controls are different from conventional controls.
If operating a CCS/EH configuration the first time, remember
the following:
• You will need some time to become completely familiar
with the new controls.
• You may not be able to operate this machine as smoothly
as your previous machine until you become more familiar
with the controls.
• You will not be able to use the machine’s full potential until
you become familiar with CCS and the various machine
controls.
Before operating the machine, get familiar with the new
controls:
• Take the machine onto a clear area. Go forward and reverse
in a straight line while practicing up-shift and downshift
commands.
• Load a few buckets from a pile to get the feeling with
CCS and E/H
• Simulate truck loading
• Practice load and carry, first slowly and progressively faster
over time
• Do not force the steering control, the machine articulates
at a given speed regardless of your effort. Your movements
are effective when smooth and continuous.
• Like when driving a car, focus your vision in front of
the bucket to avoid over-steering.

Benefits of the electro-hydraulic
implement controls: 5
• Very low efforts to activate the
hydraulic functions (fingertip operations)
• Very short stroke
• Lift kickouts adjustable from the cab, improving versatility
and productivity
• Lift kickouts are cushioned, for better comfort and more
durability of components
• A service technician is able to electronically adjust the
dump and lift speeds to optimize hydraulic performance
depending on the application

Lift, return-to-dig and tilt kick-out adjustment

The ‘In-cab’ programmable kick-outs, located in the upper
right panel, provide more flexibility and improve productivity
when the job requires multiple loading and jump target heights.
1 Tilt kick-out adjustment:
• Position the bucket/work tool a the desired tilt 2
angle with the lift arms at the desired working
level and press the rocker switch to the bottom 1
position for 1 second.
2 Lift and Return-To-Dig kick-out adjustment:
• For the lower kick-out (Return-To-Dig), position the lift
arms under the middle point of the lift range; set the lift
arms at the desired height and press the kick-out switch
(2). The lower kick-out is normally used for a cushioned
return to dig position.
• For the upper kick-out, position the lift arms above the
middle point of the lift range; set the lift arms at the
desired height and press the kick-out switch. The upper
kick-out is normally used to adjust your bucket dump
height to truck sideboard or hopper height for optimum
cycle times.

20
Loading conditions necessary to start Autodig
• Linkage near the ground (less than 2 seconds);
bucket near level
• 1st, 2nd or 3rd gear forward
• No directional changes in last 2 seconds
• No gear changes in last 0.5 seconds,
neutralizer is not active
• Lift and tilt levers are centered

Operation of Autodig Control System

• Toggle the Operation Mode Switch until the desired
Mode is selected. Automatic Pile Detection Mode for
most situations.
• Choose the optimal position on the Dig Mode Selector
(10 position rotary switch). Operator will determine
the optimal setting based on the material.
• Approach and enter the pile as you normally would,
except do not touch the bucket/work tool levers,
neutralizer pedal, or directional controls until
the bucket is fully racked back or the lift arms have
reached the Autodig kick-out height.
• If the Operator Triggered Mode (14)
14
has been selected it will be necessary
to press the trigger switch as the pile
is entered to activate the bucket
loading cycle.
• The operator may take control at any
time by moving the lift or tilt lever.
• Activating the neutralizer or shifting to neutral or reverse
will cause the bucket to quickly rackback and end
the loading cycle.

21
 Key operating functions...
Variable Shift Control
Variable Shift Control (the switch is
located in the right-side headliner) 1
allows the operator to select the
2
engine rpm at which the
transmission shift points occur,
3
better matching to the application
requirements and to his operating 4
preference.
There are 3 unique shift curves that
can be selected:
1 In the aggressive mode, the transmission will shift at
around 2100 rpm.
2 The middle position is considered the “normal” operating
position for most applications. It allows the transmission to
upshift at lower engine rpm.
3 The right most position is the “economy” position. This
mode allows the transmission to upshift at even lower
engine rpm (approximately 1300 to 1500 rpm).
4 ISO symbol for fuel efficiency

22
Transmission controls
Selecting the transmission mode
Manual mode
When the switch is positioned on the hand, the operator is
required to up-shift and downshift manually.
The transmission will automatically downshift to 2nd gear if
the left hand brake is applied.
Automatic mode 1
1 Machine equipped with HMU
• When the switch is positioned
on 2-4, the transmission is
downshifted to 2nd gear.
On the other hand, if the switch is
positioned on 1-4, the transmission
will be downshifted to 1st gear as
the machine slows down. In both 2
modes, the maximum gear is being
selected with the lever on the
steering column.
2 Machine equipped with CCS
• When the transmission mode
selector is in 4, 3 or 2, the trans-
mission will be downshifted to 2nd gear as the machine
slows down and up-shift automatically to 4th, 3rd or
2nd gear.
• When the 1-4 automatic mode position is selected,
the transmission is downshifted to 1st gear as the machine
slows down and up-shifted to 4th gear.

Shift Patterns. The left-most position provides an aggressive
shift pattern identical to earlier G models without VSC. In
this position, the transmission upshifts at higher engine rpm,
approaching high idle (2100 rpm). This position is suitable
for dedicated truck loading or cycles where the operator
desires the most aggressive shifting pattern. The middle
position is considered the “normal” operating position for
most applications. It allows the transmission to upshift at
lower engine rpm, providing the best combination of shift
smoothness, productivity and fuel economy for most
applications. The right most position is the “economy”
position. This mode allows the transmission to upshift at even
lower engine rpm (approximately 1300 to 1500 rpm). In
addition to lower sound levels and smoother shifts, it can
provide improved fuel efficiency. Field tests demonstrate that
selecting “economy” when operating in load and carry
applications can reduce fuel consumption between four and
six percent. When in doubt, operators should select the
middle position. Field-testing has demonstrated that most
operators prefer this position when performing a variety of
operations thanks to improved transmission shift quality and
reduced sound levels.

1 Downshift logic only

2 Brake Application Initiated
3 Neutralizing
4 More Agressive Braking plus Downshift
5 Max. Brake Travel
The Integrated Braking System consists of 2 brake pedals.
The left brake pedal provides automatic downshifting,
transmission declutch and application of the service brake.
The right brake pedal applies the service brakes only.
The right service brake pedal should be used when the
operator does not want the more aggressive transmission
downshifting associated with the left pedal brake control.
The right pedal is recommended for stopping on very slippery
surfaces where the more aggressive downshifts may cause
wheels to slip.
It is recommended that the left brake pedal be used under
most conditions with adequate traction. Depressing the left
pedal sends a brake pedal position signal to the transmission
electronic control and also applies the service brakes.
The transmission electronic control monitors the pedal
position, machine ground speed, engine speed, and
transmission control mode selector switch position.
The electronic transmission control downshifts and
declutches the transmission based on left brake pedal position
and machine ground speed.

26
The left brake pedal travel consists of 2 ranges. The initial
range consists of pedal travel from 4 degrees of pedal travel
to the pedal position where brakes start to apply. The brake
application range consists of the pedal position where the
service brakes begin to be applied to the maximum brake
pedal position.
In the left pedal initial pedal range, the engine and trans-
mission retard the machine. No up-shifting will occur unless
the machine travelling speed increases to the previous
downshift point. Thus, the left pedal can be used to maintain
a lower gear than the normal transmission Automatic shift
control would provide. This is ideal for retarding the machine
while travelling down hill.
Downshifting is inhibited if it would cause an immediate
engine or transmission over speed. Also, the transmission
will be up-shifted, if not in top gear, to avoid an engine or
transmission over speed.
If the left brake pedal is pushed beyond the initial range,
the service brakes are applied to increase the braking force.
The transmission will downshift automatically as the machine
slows down to the lowest available gear based on the trans-
mission mode switch position.
When the brake pedal is fully released and the transmission
is in an Automatic Shift Mode, the transmission is returned to
the automatic transmission control. For Conventional steering
machines with the Manual Shift Mode selected, the trans-
mission will be up-shifted sequentially to the gear selected
by the shift lever when the left pedal is released. For CCS
machines operating in Manual Mode, the transmission will
remain in the gear that is in effect at the time the left brake
pedal is released.

27
 Transmission declutch and
neutralizer switch
The transmission declutch control is active when the machine
is started. When the left brake pedal is depressed beyond
the initial declutch position; the transmission will be shifted
to neutral after the transmission has been downshifted to
the lowest gear allowed by the transmission mode selected.
The transmission will be re-engaged when the pedal is
released 2 degrees from the maximum pedal position that was
obtained after declutching occurs. This provides a method to
re-engage the transmission with brakes applied to prevent
unwanted machine movement on a slope. (The operator
should wait at least 1 second after releasing the pedal
2 degrees to allow the transmission clutches to engage before
completely releasing the brake pedal. Also, the operator must
provide enough engine speed to create required drawbar to
avoid unwanted machine movement on a slope.) When in all
transmission control mode switch positions other than 2
for CCS machines and 2-4 Automatic with gear selector in 2,
the transmission will be declutched again when the left pedal
is returned to the previous maximum pedal position.
When in the 2nd gear truck loading position (2 for CCS
and 2-4 with gear selector in 2 for Conventional Steering
Machines), the transmission will declutch again after
depressing the pedal 2 degrees from any pedal position after
the pedal has been released to re-engage the transmission.
The initial declutch pedal position has been factory set for
optimum smoothness in a level truck loading application.
The initial declutch pedal position is electronically adjustable.
Consult your Caterpillar dealer if adjustment is desired.
The declutch feature can be disabled by depressing
the momentary contact switch. The light in the dash
is illuminated to indicate that the transmission declutch
is not active when depressing the left brake pedal.

28
The transmission neutralizer switch
has two positions:
– OFF: Push the top of the switch to select
the OFF position. A light on the dashboard will
turn ON. In this position, transmission will not
be neutralized when braking with the left pedal.
– ON: Push the bottom of the switch to select the ON
position. The light on the dashboard will turn OFF. If the
ON position is selected, the transmission will be neutralized
when you apply the left service brake. This position is the
default position when starting the machine.

On-demand fan
How it works
On-Demand Fan Operation:
• Temperature sensing on-demand
fan slows fan speed when cooling
system temperatures are lower,
increasing available power and
fuel efficiencies. This also allows
the engine to more quickly reach
the normal operating temperature
range.
• When the cooling system temperature reaches the target
level, the fan will activate and run at the lowest speed
possible to maximize horsepower efficiency.
• As cooling system temperature rises, the fan speed will
automatically increase to provide adequate cooling
capacity.
• Lower average fan speeds contribute to lower sound levels
and less radiator plugging.

29
 Ride control (if equipped)
Ride control benefits

Nitrogen over oil accumulator in the hydraulic lift circuit acts

as a shock absorber for the bucket. When the machine travels
over rough ground, Ride Control reduces machine bouncing
by allowing the bucket and lift arms to compress the nitrogen
in the accumulator for a smoother, more comfortable ride.
Ride Control gives operators more confidence to travel at
higher speeds during load and carry, improving cycle times
and load retention for better productivity. Ride Control also
contributes to increased frame life by reducing shock loads
into the structures.

30
Ride control switch
The ride control switch,
located in the upper right 1
panel, selects three modes:
2
1 Automatic: push the top
of the switch to use 3
the Automatic position.
In automatic mode,
the Ride Control System
automatically activates at ground speeds
exceeding 9.7 km/h and deactivates at ground speeds
less than 9.7 km/h*.
2 OFF: push the switch to the middle position to turn
the system OFF.
3 ON: Push the bottom of this switch to turn
the Ride Control System ON.
The Ride Control System is activated
for all ground speeds.
Bucket loading should be done only with Ride Control
in the “Automatic” (1) or “Off” (2) positions. Loading in
the “On” (3) position will result in poor pile penetration.
The lights on the dashboard indicate the selected mode.
* Factory setting. The speed at which the ride control is activated
(in automatic mode) can be adjusted using the Electronic Technician
service tool.

31
 Before you operate the machine...
• Read the Owning an Operating Manuel and perform daily
maintenance inspections.
• Set the transmission controls, Variable Shift Control,
transmission neutralizer, and ride control to the desired
setting for your application.
• Set the lift, return-to-dig, and tilt kick-outs for your
application.
• Check the time required going from full articulation left to
full articulation right. Standard time is 3 to 4 seconds at
high idle and bucket empty.
• Check the value of single and double stall speed.
To reach single stall speed:
• Start the engine and go to full throttle.
• Apply the service brake (not the parking brake) without
neutralizing the transmission.
• Engage third gear.
• Read the engine speed and compare it with the table
below.
To reach double stall speed:
• Reach single stall speed.
• Fully rack the bucket to put the hydraulic system in relief.
By these two operations you get the maximum engine
solicitation.
• Read the engine speed and compare it with the table
below.

When you get out of the machine...

Engine Shut Down Procedure

a It's recommended to park the machine on a level place
(Parking area must be free of personnel and obstacles).
b Apply "Service brake" by pressing the pedals (Left pedal is
recommended for IBS)
c Put the transmission in neutral.
d Apply the Parking Brake. You can release the service brake.
e Lower the lift arm and the bucket or work tool to the
ground.
f Stop the engine by turning the engine start switch to the
"Off" position and remove the key.
g Pull forward "Tilt" and "Lift" levers to release any
hydraulic pressure.
h For a safety step out of the machine, raise the steering
control & deactivate the loader hydraulic system or
functions that can be inhibited.

Recommendations
• After the machine has been operated under load, it's
recommended to allow engine idle five minutes before
shutdown. This allows hot areas of the engine to cool
gradually. Apply this procedure after previous "e" item.
• If the machine will not be operated for an extended period
of time, turn the battery disconnect switch to the off
position. (Please refer to Operation and Maintenance
Manual for location detail).
• It's always recommended to remove the Start key for
vandalism protection and avoid any potential battery
discharge.
• Always refer to Operating Manual in case of any doubt.
