WINDSHIELD WASHER RESERVOIR
This reservoir, located in the compartment behind the
cab, is equipped with an electric pump which is oper-
ated from the control panel. See "Systems display and
control panel" (item 7).
IMPORTANT: Never operate the windshield washer
control when the reservoir is empty. This could
cause damage to the electric pump.
Remove the cap to add windshield washing fluid.
NOTE: In cold weather, add anti-freeze to the wind-
shield washer water.
The reservoir can be lifted out of its support. CT05L004A

CAB PROTECTION (F.O.P.S.) (optional)
F.O.P.S.: Falling Objects Protective Structure.
It is essential that the cab protection is used when
work takes place in areas where stones or debris may
fall or during forestry work. If the machine was not orig-
inally equipped with this protection, consult your CASE
Dealer for its installation.

SECTION 5 - OPERATING INSTRUCTIONS
ANTI-THEFT DEVICE
To prevent the machine from being stolen it is possi-
ble to use the anti-theft device, which makes it nec-
essary for a special code to be entered before the
machine can be operated.
To configure the anti-theft device, consult your
CASE Dealer.
The effects of the device are:
- The engine runs at idle speed.
- The audible alarm device will sound.
- The engine stops if the machine is handled.
Once the machine has been configured, a special
access code has to be recorded which must be
entered whenever you start the engine.
IMPORTANT: Once the code has been recorded, do
not forget it, as it can not be changed without con-
sulting your CASE Dealer.
RECORDING THE CODE
1. Turn the starter switch key to the "ON" position.
2. The message "PASSWORD?" and four boxes will
appear on the display screen.

MACHINE TRAVEL
! WARNING !
In the normal travel position, the operator's com-
partment is above the idler wheels and the travel
reduction gears are to the rear of the upperstruc-
ture. If the upperstructure is turned 180° in relation
to the undercarriage, the controls are reversed.
IMPORTANT: Before undertaking any travel, raise the
attachment.
NOTE: Travel speed depends on the tilting angle of
the travel control levers and pedals and the speed
travel mode selected.
NOTE: The different travel configurations described
hereafter are with the travel reduction gears to the
rear of the upperstructure.

SETTING THE TRACKS IN TRANSPORT POSITION
IMPORTANT: Narrow track gauge or transport posi-
tion must in no event be used for any purpose other
than transporting the machine.
IMPORTANT: Do not allow anybody to stand within
the machine working area.
1. Place the upperstructure at right angles to the
undercarriage and lay the bucket flat on the
ground.
2. Remove the 24 pieces of mounting hardware (2).

DRAINING, CHANGING THE OIL FILTERS AND FILLING
NOTE: Change the oil while the engine is still warm.
The oil will flow more easily.
Use the extension drain hose from the front boot.
1. Park the machine on flat, horizontal ground. Shut
down the engine, remove the starter switch key
then open the hatch under the engine.
2. Raise and lock the engine hood, open the access
hatch then remove the filling cap.

3. Remove the protective cap from the engine hous-
ing drain valve.
4. Screw the end of the extension drain hose onto
the engine check valve, place the other end in a
container of suitable capacity and allow the oil to
flow out.
5. Remove the extension drain hose and install the
protective cap on the housing check valve. Place
the extension drain hose in the front storage com-
partment.

FUEL SYSTEM AIR BLEED
It is necessary to bleed the fuel system when:
- The tank has been completely emptied.
- The fuel pre-filter has been changed.
- The fuel filters have been replaced.
- Parts of the fuel system have been removed for serv-
icing or repair work.
- The machine has been in storage for a fairly long
period.
1. Turn the starter switch key to the "ON" position.
! WARNING !
Do not leave the starter switch key in the "ON"
position for more than five minutes unless bleed-
ing has been performed. It may damage the fuel
supply pump.
2. Loosen the bleed screws (1) on the fuel filter (2).
3. Turn the priming pump piston (3) of the fuel filter
(2) to the left in order to release the spring.

4. Place a receptacle of a suitable capacity under the
reservoir drain plug. Open the access hatch then
remove the drain plug to remove the remaining
fluid from the reservoir.
5. Change the inlet filter and the return filter. See
"Cleaning and replacement of the inlet filter" and
"Return filter replacement".

important that you bleed air from all the hydraulic
components. See "Bleeding air from the hydraulic
components".
9. Start and run the engine with no load for approxi-
mately five minutes.
10. Move each control several times to remove any
air in the system.
11. Swing the upperstructure evenly left to right two
complete turns or more.
12. Place the machine in position and then stop the

SECTION 8 - MAINTENANCE/ADJUSTMENTS
WELDING ON THE MACHINE
Whenever carrying out a welding operation on the
undercarriage or upperstructure carriage as authorized
by the manufacturer and in accordance with his
instructions, disconnect the batteries, disconnect the
alternator B+ and D+ terminal wires and connect the
welding apparatus earth cable to the component on
which the welding operation is to be performed. Never
connect the welding apparatus to the undercarriage
when welding on the upperstructure (or vice-versa).
Never connect the welding apparatus earth to a com-
ponent of the hydraulic system.

MAINTENANCE SPECIFICATIONS
Inspect and clean...........................................................................................................................................Periodically
Or whenever oil or grease has been spilt on the
machine. Clean off with steam or a high pressure
water jet.
Take the opportunity during this operation to make a
