6. Lubricate the gasket on the new filter and screw
this in until the gasket touches the surface of the
engine. Then tighten the filter a further turn us-
ing an oil filter wrench.

8. Fill with new oil according to "5.3".
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 "5.3".
6.9 CHANGING HYDRAULIC OIL,
FILTER
No contaminants must enter the hy-
draulic system. This causes serious
damage to components of the systems.
Change hydraulic oil and filter as follows:
1. Place the machine on a level surface.
2. Clean the area around the filter (27:A) thor-
oughly on the upper part of the hydraulic tank
and remove the filter.
3. Place a container under the oil drain plug
(27:C), remove the plug and let the oil run out
into a container. The container must have a ca-
pacity of 20 litres.
4. Dispose of the oil according to local regula-
tions.
5. Install the oil drain plug. Tighten to 40 Nm.
6. Replace the tank vent valve (28:H). The valve is
unscrewed and the new one is installed in re-
verse order.
7. Fill with new oil through the filter opening at
the top.
Oil: See "2.1".
Oil quantity when changing: See "2.1".
8. Reinstall the filter with the following compo-
nents:
28:DCover
28:GGasket. Check that the washer is intact.
28:FNew filter. The filter must always be re-
placed when changing the oil.
28:ESpring
9. After filling the oil, start the engine and run the

6.10CHANGING THE OIL IN THE
WHEEL MOTORS
Change the oil in the gear housing of the wheel
motors as follows:
1. Place the machine on a level surface.
2. Clean carefully around the
oil plugs (21:X, Y).
3. Place a container under the oil drain plug
(21:X), remove the plug and let the oil run out
into a container.
4. Remove the filler plug (21:Y).
5. Install the oil drain plug.
6. Dispose of the oil according to local regula-
tions.
7. Fill with new oil via the filler plug hole. Pump
in the oil with help of an oil can. Fill until the
level reach the the filler plug hole.
Regarding type and volume of oil, see the table
in "2.1".
8. Install the filler plug.
9. Tighten the plugs to 30 Nm.
6.11 BELT TRANSMISSIONS
After 5 hours of operation check that all belts are
intact and not damaged.
6.12CLEANING THE COOLING SYS-
TEM
After the engine is run, the coolant becomes con-
taminated by rust and deposits. This deteriorates
the coolant's capacity to draw heat from the en-
gine. Therefore, the coolant must be changed reg-
ularly.
Change the coolant as follows:
1. Check that the engine is completely cold.
2. Remove the front engine cover and unscrew the
radiator cap (13:C).
3. Place a drip tray under the radiator's lower hose
(fig. 23) and under the engine's coolant plug
(22:X).
4. Detach the hose from the lower part of the radi-
ator so that the used coolant runs into the drip
tray. See fig. 23.
5. Remove the engine coolant plug so that the used
coolant runs into the drip tray.
6. Flush the coolant system from the filler hole
with running water from a water hose until the
system is clean.
7. Reinstall the hose in the lower part of the radia-
tor and reinstall the coolant plug.
8. Fill with new coolant according to "5.4".
Tighten to 40 Nm.
