Check that air can pass unobstructed through the
5
radiators (1), (2) and (3).
1
Clean a dirty radiator using compressed air or a
high-pressure water jet.
Undo the two screws (5) and tilt the condenser
element upwards.
Blow air or direct water through the cooler in the
opposite direction to that of the cooling air.
Be careful when using a high-pressure washer -
2
do not place the nozzle too close to the radiator.

Fuel pre-filter - Replacement
Ensure good ventilation (air extraction) if the
diesel engine is run indoors. Risk of carbon
monoxide poisoning.
See the engine's instruction manual for filter
replacement, in the Fuel system chapter.

Replacing the fuel filter
Place a container underneath to collect fuel that runs
out when the filter is released.
Screw off the fuel filter (1). The filter is of the
disposable type and cannot be cleaned. Han in to
environment-friendly station.
Deliver the drain oil to environmentally correct
handling.

Refer to the engine manual for detailed
instructions when replacing the fuel filter.

Start the engine and check that the fuel filter is tight.
Ensure good ventilation (air extraction) if the
diesel engine is run indoors. Risk of carbon
monoxide poisoning.
NOTE! The new fuel filters must not under any
circumstances be pre-filled with fuel due to the purity
requirements of the fuel system.

Diesel engine - Oil and Filter change
The oil drain plug (1) can be accessed most easily
from the right rear underside of the tractor frame, and
is installed with a hose in the engine.
Drain the oil when the engine is warm. Place a
receptacle that holds 19 liters (5 gal) under the drain
plug.
Replace the engine oil filter (2) at the same time. Refer
to the engine manual.

Seat bearing - Lubrication
5
Keep in mind that the chain is a vital part of the
steering mechanism.
6
Remove the cover (5) to access the lubrication nipple
(1). Lubricate the operator seat slew bearing with three

strokes of a hand-operated grease gun.
Clean and grease the chain (3) between the seat and

If the seat starts to be stiff when adjusting, it
should be lubricated more often than specified
here.
Hydraulic reservoir - Draining
The condensate from the hydraulic reservoir is drained
through the drainage tap (1).
Drain the roller after it has been stationary for a long
time, e.g. after standing overnight. Drain as follows:

Remove the plug (2).
Place a container under the tap.

Open the tap (1) and let any trapped condensate run
out.
Shut the drainage tap.

Fuel tank - Draining (Optional)
Water and sediment in the fuel tank are removed via
the drainage plug in the bottom of the fuel tank.
Be very careful during draining. Do not drop the
plug or else all the fuel will flow out.
Drain the roller after it has been stationary for a long
2
time, e.g. after standing overnight. The fuel level
should be as low as possible.
1
The roller should preferably have been standing with

will gather near the drainage plug (1). Drain as follows:

Loosen the drain plug (1). Then open the drain cock
(2) and drain out water and sediment until only pure
diesel fuel emerges at the plug. Close the drain cock
and screw in the plug again.
Air conditioning (Optional)
Fresh air filter - Change
2
Use a step ladder to reach the filter (1). The filter

can also be accessed via the right cab window.
There is a fresh air filter (1), located at the front of the
cab.
Undo the three screws (2) and remove the protective
cover.

It may be necessary to change the filters more often if
the machine is working in a dusty environment.

Automatic Climate Control (Optional)
- Overhaul
Regular inspection and maintenance are necessary to
1
ensure satisfactory long-term operation.
Clean all dust from the condenser element (1) using
compressed air. Blow from underneath.
The air jet can damage the element flanges if it is
too powerful.
Fig. Engine compartment
1. Code element
Wear protective goggles when working with
compressed air.
Inspect the condenser element attachment.
Drying filter - Check
1
2
With the unit in operation, open the engine hood and
check using the sight glass (1) that bubbles are not
visible on the drying filter. If bubbles are visible
through the sight glass, it is a sign that the refrigerant
level is too low. If so, stop the unit. The unit may be
damaged if it is run with insufficient refrigerant.
Check the moisture indicator (2). It should be blue. If it
is beige, the dryer cartridge should be changed by an
authorized service company.
The compressor will be damaged if the unit is run
with too little refrigerant.
Do not disconnect or undo the hose couplings.

The cooling system is pressurized. Incorrect
handling can result in serious personal injury.
The system contains pressurized refrigerant. It is
forbidden to release refrigerants into the
atmosphere. Work on the refrigerant circuit is only
to be carriedd out by authorized companies.

Steering hitch - Tightening
Nobody must be allowed near the steering joint
when the engine is running. Risk of being
crushed when the steering is operated. Switch
off the engine and activate the parking brake
1
before lubricating.
The easiest way to identify if you have this type of
steering hitch is that it has a new type of nut (1) at the
top, as shown.
