Operation
Dust valve - clean
Empty the dust valve (1) by pressing it together several times.
Engine oil - check
Pull out the oil dipstick (1) and wipe it with a clean cloth.
Insert the oil dipstick completely and pull it out again. The oil
level should be in the "A" area. If the oil level is too low, add en-
gine oil (page 189).
Coolant level - check
Check the level of the coolant in the expansion tank (1).
The fluid level must be between FULL (A) and LOW (B).
If the oil level is too high or too low, the engine might
get damaged during operation.
Do not mix engine oils from different brands!
Before filling in a different brand of engine oil, drain the
engine oil completely.
Do not open the radiator cap.
If the coolant level is below the LOW mark, refill cool-
ant (page 182).
Do not mix coolant from different brands!
