nance work described in this chapter must be fol-
lowed according o the instructions and at the stated
intervals.
This work should be carried out by an authorised
workshop, but can also be carried out by the user.
Service, carried out by authorised workshops,
guarantees a professional job with original re-
placement parts.
We recommend taking the machine to an author-
ised workshop after each season before it is stored
for the winter.
6.2 Preparation
Prevent the machine from rolling by al-
ways applying the parking brake.
Prevent unintentional starting of the
engine by removing the ignition key.
All service and all maintenance must be carried out
on a stationary machine with the engine switched
off.
6.3 Raising
Jacks must only be placed in the desig-
nated area. Placing the jack in other lo-
cations will damage the machine.
The machine must only be raised on
hard, stable and horizontal surfaces.
Otherwise there is a risk of the machine
dropping.
The machine must never be loaded with
further weight when it is raised. No-
body must sit on the machine when it is
raised.
For certain maintenance work, the rear part of the
machine must be raised slightly so that the re-
quired rear wheel can be removed. Raise the ma-
chine as follows:
1. Position the machine on a hard, stable and hor-
izontal surface.
2. Raise the machine using a jack, see fig. 12.
6.4 Wheels
For certain maintenance work, it is necessary to re-
move a rear wheel.
Dismantling
:
1. Raise the machine according to 6.3.
2. Remove the cover disc (13:A).
3. Use a 17 mm wrench and remove the screw
(13:B) with disc.
4. Pull the wheel from the axle.
Assembly
:
1. Slide the wheel onto the axle.
2. Install the screw (13:B) with disc.
3. Tighten the screw to 40-45 Nm.
6.5 Tyre pressure
Adjust the air pressure in the tyres as follows:
Front:
1.2 bar (17 psi).
Rear:
1.2 bar (17 psi).
If the maximum tyre pressures are exceeded the
safety valve (13:C) will be triggered. If this occurs,
reset as follows:
1. Wait until the tyre has no pressure.
2. Press in the safety valve using a finger.
3. Fill with air to the specified pressure.
6.6 Changing engine oil
Change the engine oil for the first time after 5
hours of operation, and subsequently after every
50 hours of operation or once a season.
Change the oil more often (after 25 hours of oper-
ation or at least once a season) if the engine has to
operate under demanding conditions or if the am-
bient temperature is high.
Use oil according to the table below.
Use oil without any additives.
Do not fill with too much oil. This can cause the
engine to overheat.
Change oil when the engine is warm.
The engine oil may be very hot if it is
drained off directly after the engine is
shut off. So allow the engine to cool a
few minutes before draining the oil.
6.6.1 Draining
1. Raise the machine so that the left rear wheel is
raised a few cm above the ground. See 6.3.
If the machine is raised too much, oil cannot
run freely in the chassis ducts whilst drain-
ing.
2. Remove the left-hand rear wheel. See 6.4.
3. Place a suitable container under the drain hole
(8:W) in the machine’s chassis.
4. Insert a 10 mm Allen key through the hole (8:X)
in the chassis and unscrew the oil drain plug
(9:Y) from the engine. Leave the oil drain plug
in place on the Allen key inside the engine com-
partment.
Do not spill any oil on the drive belts.
5. Reinstall the oil drain plug (9:Y) once all the oil
has been drained.
Tightening torque: 20 Nm.
6. Remove the dipstick (7:S) and fill with new oil.
Oil capacity: 1.2 litres.
7. Reinstall the dipstick (7:S).
8. Use a cloth or similar and wipe clean the oil
duct in the chassis.
Oil SAE 10W-30
Grade SJ or greater
