Backrest adjustment

Take the load off the backrest and pull up the backrest adjustment lever (figure above, position 1). Set the
backrest to the desired sitting position and release the lever. The backrest should be adjusted so that the
operator can safely operate the control levers with the back resting completely on the backrest.

Fasten the seat belt.
•
Adjust the length of the seat belt by lengthening or shortening the belt so that the belt fits comfortably.
Do not operate the excavator without the seat belt fastened.
Exterior mirror adjustment

Check the adjustment of the exterior mirrors. If necessary, adjust the mirrors until the optimum sight is
ensured.
Safety instructions for starting the engine
The excavator is equipped with an anti-theft system (page 84).
When starting the excavator for the first time on a work day, carry out the pre-operational ser-
vices (page 49).
Make sure that there are no persons within the excavator's working area. It is essential to warn
persons in the vicinity of the excavator by briefly honking the horn.
Make sure that all operational controls are in the neutral position.
Starting the excavator is only allowed when the operator is sitting on the operator's seat.
Before starting the engine, make the necessary operator station adjustments (page 53).
If the engine does not start immediately, cease the starting procedure. Wait a short time before
reattempting a start. If the engine does not start after several attempts, contact skilled personnel.
If the battery is discharged, jump-start the excavator (page 78).
Do not use Start Pilot or similar substances as a starting aid.
