5.2 Preparation
All service and all maintenance must be carried out
on a stationary machine with the engine switched
off.
Prevent the machine from rolling by al-
ways applying the parking brake.
Stop the engine.
Prevent unintentional starting of the
motor by always stopping the motor
and disconnecting the negative cable
from the battery.
5.3 Tyre pressure
Adjust the air pressure in the tyres as follows:
Front: 0.6 bar (9 psi).
Rear: 0.4 bar (6 psi).
5.4 Changing engine oil
The engine oil must be changed for the first time
after 25 hours of operation and then every 250
hours of operation.
Use the following oil specifications:
ACEA-B2-E2 or API-CF-CG or SHPD.
Select the oil grade according to the table below.
Use oil without any additives.
Do not overfill with 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.
1. Push the drain hose down so that it comes out
under the engine. See fig. 12
2. Tighten the clamp on the oil drain hose. Use a
polygrip or similar.
3. Move the clamp 3-4 cm up the oil drain hose
and pull out the plug.
4. Collect the oil in a container.
NOTE! Do not spill any oil on the drive belts.
5. Dispose of the oil according to local regula-
tions.
6. Install the oil drain plug and slide the clamp
back so that it clamps over the plug.
7. To clean the oil filter, see 5.4.1 below before
continuing.
8. Remove the filler cap (11:C) and fill with oil.
The engine has a capacity of around 1.7 litres.
9. After filling the oil, start the engine and run at
idle speed for 30 seconds.
10.Check to see if there is any oil leakage.
11.Stop the engine. Wait for 30 seconds and then
check the oil level. See 4.3. Top up the oil if
necessary.
5.4.1 Oil filter
The oil filter must be cleaned after 1000 hours of
operation and when changing the oil. First drain
the engine oil and install the oil drain plug as
above. Then clean the oil filter as follows:
1. Clean the area around the filter (13:A)
2. Slacken off the screw (13:B) 5 turns.
3. Pull out the oil filter.
Never direct the flow of compressed air
towards the body. The penetration of
air into the blood stream can be fatal.
4. Clean the filter by blowing compressed air in
and out of the filter. See fig. 14.
5. Check/replace the gasket (14:D).
6. Lubricate the gasket (14:D) and slide the filter
in to its limit position.
7. Check that the ends of the tensioner spring
(13:C) lie flush against the filter. Tighten the
screws (13:B).
8. Continue with point 7 according to “5.4 Chang-
ing engine oil” above.
5.5 Engine screws
All screwed joints on the engine must be check-
tightened after 25 hours of operation and then ev-
ery 250 hours of operation.
Exceptions:
• The cylinder head screws must not be touched.
• The fuel injection system’s adjustment screws,
as illustrated in fig. 15, must not be touched.
5.6 Fuel filter
The fuel filter (10:E) must be replaced after every
500 hours of operation.
After replacing, the fuel system must be bled. See
“4.2”.
Check that there is no fuel leakage once the new
filter has been installed.
5.7 Cleaning the fuel tank
During temperature changes water from the air
will condense in the fuel tank. The amount of wa-
ter that condenses increases during large tempera-
ture changes and at high humidity. The water drops
and settles at the bottom of the fuel tank.
Condensation should be drained from the fuel tank
as necessary and at least once a year.
