7.9.2 Engine oil filter
The engine oil filter must be replaced every time
the engine oil is changed.
• Unscrew the filter cartridge (46/4) using a
tightening scrap wrench or similar tool and
dispose of in compliance with regulations.
• Clean the filter head and check its condition.
• Fill the new filter with oil, wet the seal ring with
oil and tighten firmly by hand.
• Check the tightness of the engine oil filter
cartridge.
7.9.3 Engine - Cooling system
Coolant level
Only check when the engine is cold.
Danger of scalding from hot coolant!
• Remove the cap (47/1) and check the water
level.
• The water level must be up to the overflow
pipe (47/2).
Top up with a mixture of 50% water and
50% antifreeze.
Water cooler - Cleaning cooling fins
Dirt accumulation in coolers causes the
engine to overheat.
• Clean the water cooler from the outlet side with
compressed air.
• If necessary, e.g. if there is oil in the cooler,
clean with cold cleaner or a steam jet
appliance.
When cleaning with the aid of a steam jet
appliance, the cleaning area must be
equipped with an oil separator.
After cleaning, run the engine until it
reaches operating temperature, to dry the
cooler.
