Operation
Dust valve - clean
Empty the dust valve (1) on the air filter cover (2) by pressing it
together several times.
If it is very dirty, remove the air filter and clean it (page 123).
Engine oil level - 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 128).
If the oil level is too high or too low, the engine might
become damaged during operation.
Coolant level - check
Check the coolant level in the expansion reservoir (1). The fluid
level must be between FULL and LOW.
Do not open the radiator cap.
STOP
If the coolant level is below the LOW mark, refill cool-
ant (page 92).
If the coolant level is below the LOW mark a short time
after adding coolant, then the cooling system is leaky.
The excavator may only be started again after the fault
is repaired.
