6.7 Changing engine oil, filter<br />
The engine oil may be very hot if it is<br />
drained off directly after the engine is<br />
shut off. So allow the engine to cool a<br />
few minutes before draining the oil.<br />
Change engine oil and filter as follows:<br />
1. Place the machine on a level surface and run the<br />
engine to operating temperature.<br />
2. Stop the engine and remove the oil filler cap<br />
(10:J).<br />
3. Place a container under the oil drain plug<br />
(11:N), remove the plug and let the oil run out<br />
into a container.<br />
4. Dispose of the oil according to local regulations.<br />
5. Clean the area around the oil filter (11:M) and<br />
remove the filter. Use an oil filter wrench.<br />
6. Lubricate the gasket on the new filter and screw<br />
this in until the gasket touches the surface of the<br />
engine. Then tighten the filter a further turn using<br />
an oil filter wrench.<br />
7. Install the oil drain plug. Tighten to 60 Nm.<br />
8. Fill with new oil according to “5.3”.<br />
9. After filling the oil, start the engine and run at<br />
idle speed for 30 seconds.<br />
10.Check to see if there is any oil leakage.<br />
11.Stop the engine. Wait for 30 seconds and then<br />
check the oil level. See “5.3”.<br />
6.8 Changing hydraulic oil, filter<br />
No contaminants must enter the hydraulic<br />
system. This causes serious<br />
damage to components of the systems.<br />
Change hydraulic oil and filter as follows:<br />
1. Place the machine on a level surface.<br />
2. Clean the area around the filter (16:A) thoroughly<br />
on the upper part of the hydraulic tank<br />
and remove the filter.<br />
3. Place a container under the oil drain plug<br />
(16:C), remove the plug and let the oil run out<br />
into a container. The container must have a capacity<br />
of 20 litres.<br />

4. Dispose of the oil according to local regulations.<br />
5. Install the oil drain plug. Tighten to 40 Nm.<br />
6. Fill with new oil through the filter opening at<br />
the top.<br />
Oil: See “2.1”.<br />
Oil quantity when changing: See “2.1”.<br />
7. Reinstall the filter with the following components:<br />
17:D Cover<br />
17:G Gasket. Check that the washer is intact.<br />
17:F New filter. The filter must always be replaced<br />
when changing the oil.<br />
17:E Spring<br />

machine for a few minutes and check for oil<br />
leakage.<br />
9. Check the oil level. See “3.5.8”.<br />
6.9 Changing the oil in the wheel<br />
motors<br />
Change the oil in the gear housing of the wheel<br />
motors as follows:<br />
1. Place the machine on a level surface.<br />
2. Clean carefully around the<br />
oil plugs (18:X, Y).<br />
3. Place a container under the oil drain plug<br />
(18:X), remove the plug and let the oil run out<br />
into a container.<br />
4. Remove the filler plug (18:Y).<br />
5. Install the oil drain plug.<br />
6. Dispose of the oil according to local regulations.<br />
7. Fill with new oil via the filler plug hole. Pump<br />
in the oil with help of an oil can. Fill until the<br />
level reach the the filler plug hole.<br />
Regarding type and volume of oil, see the table<br />
in “2.1”.<br />
8. Install the filler plug.<br />
9. Tighten the plugs to 30 Nm.<br />
6.10Belt transmissions<br />
After 5 hours of operation check that all belts are<br />
intact and not damaged.<br />
6.11Cleaning the cooling system<br />
After the engine is run, the coolant becomes contaminated<br />
by rust and deposits. This deteriorates<br />
the coolant’s capacity to draw heat from the engine.<br />
Therefore, the coolant must be changed regularly.<br />
Change the coolant as follows:<br />
1. Check that the engine is completely cold.<br />
2. Remove the front engine cover and unscrew the<br />
