Maintenance

Removing the machine's covers

Engine cover
1. Open the engine covers on both sides.
2. Remove the screws holding the engine cover.
3. Lift off the engine cover.
Assemble in the reverse order.

Checking radiatorgrilles

Clean the radiator grille behind the driver's seat:
Fold the driver's seat up.
Check that the radiator grille is free of leaves, grass,
and dirt.
A clogged radiator grille impairs the cooling of the
engine, which may result in engine damage.
If necessary, remove the radiator grille and clean it.
Check when the grille has been removed whether the
heat exchanger is dirty. Clean if necessary.
See "Cleaning the radiator's heat exchanger" on
page 38.

Cleaning the radiator's heat exchanger

Remove the radiator grille. If the dirt is mixed with oil,
first spray cold degreasing agent and wait
approximately 5 minutes. Then flush the radiator with
water jets from the engine compartment. Dirt mixed
with oil, can be due to a leaking hydraulic oil cooler.
Contact an authorised service workshop for repair.

Adjusting the pump and generator drive belts

1. Slacken off the adjustment screw 1/2 turn.
2. Pry out the generator using a screwdriver or similar
until the belt can be pressed in approximately 1 cm
(3/8") with moderate thumb pressure between the
pump and generator. Slacken off, if necessary, the
generator's lower mounting screw if the belt cannot
be tensioned.
Caution: Do not pry against the generator housing,
pry against the bearing shield, see image.
3. Tighten the adjustment screw.
4. Check tighten the generator's mounting screw.
