Running-in of the excavator

Warm up the excavator at an average engine speed and with a low load; do not let it warm up at idling position.
!
Do not overload the excavator.
Special maintenance instructions
!
Change the oil in the final drives after the first 50 service hours.

The hydraulic system’s return filter should be changed after the first 250 service hours.
Operating the excavator
For a safe excavator operation, see the following sections.
Pre-operational services
!
Open the engine compartment cover (page 107). Close engine compartment cover after completion of the ac-
tivities.
!
Open the side cover (page 108). Always close the side cover after the work is done.
Walk-around inspection
!
Check the excavator for visible damage, loose nuts and screws and leaks.
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, refill
engine oil at the oil filler neck (page 128).
For the performance of the services, the excavator must be parked on level ground and the key must
be removed.
When the oil level is too high or too low, the engine
might get damaged during operation.
