Operating the excavator

For a safe excavator operation, see the following sections.

Pre-operational services

For the performance of the services, the excavator must be parked on level ground and the key
must be removed. Also, the control levers and the swivel frame have to be locked (page 23).

Open the engine compartment cover (page 74). Always close the engine compartment cover after the work
is done.
Walk-around inspection

Check the excavator for visible damage, loose screws and leaks.

Check the existence and legibility of the safety instructions (labels) on the excavator. Replace the safety
instructions if necessary (page 17).

Checking the engine oil level


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 engine oil (page 91).
When the oil level is too high or too low, the engine
might get damaged during operation.

Checking the coolant level


Check the coolant level in the expansion reservoir (1). The
fluid level must be between FULL and LOW.
Do not open the radiator cap.
If the coolant level is below the LOW mark, refill
(page 89).
If the coolant level is below the LOW mark a short time after adding coolant, the cooling system
is leaky. The excavator must only be started again after the fault is repaired.
