7 Care and Maintenance
7.8.2 Changing the engine oil filter
The engine oil filter must be replaced every time the
engine oil is changed.
• Place oil drip pan below the engine oil filter.
• Clean the outside of the engine oil filter.
• Unscrew the filter cartridge (35/4) using a
commercially available tool and check that the
fastening stud is firmly secured in the filter head.
• Dispose of the filter cartridge according to
regulations.
• Check filter head condition and clean.
• Fill the new filter with oil, wet the sealing ring with
oil and tighten firmly by hand.
• After a test run, check the tightness of the engine
oil filter cartridge.
7.8.3 Cooling system - combined hydraulic oil-
water cooler
7.8.3.1 Checking the coolant level
Check the coolant level daily before starting, with the
machine parked on level ground. To do so, use the
sight glass (36/2) of the combined cooler. If the
coolant level is insufficient, top up accordingly.
Danger of scalding
due to hot coolant getting into contact with
skin or eyes.
• Only open the cooler cap after the engine
has cooled down.
• Remove the cover (36/1) and top up coolant if
required. With the engine cooled down, the
compensation tank should be half full.
Attention
Refill with a 50%-50% mixture of water and
antifreeze.
7.8.3.2 Check the level of antifreeze
Before the beginning of the cold season, the
antifreeze protection must be checked.
• The antifreeze is factory-set to approx.
minus 25 °C.
If temperatures are lower, the level of antifreeze
must be adjusted accordingly.
