to the STOP position and remove the key before the
next greasing procedure.
Operate the excavator and rotate the swivel frame 90° several
times, greasing it as you go. After greasing, swivel the swivel
frame 360° several times to distribute the grease evenly.

Air filter element - check/clean

If the excavator is operated in a particularly dusty en-
vironment, the air filter must be checked more often.

Open the clips (3) and remove the cover (4).
Pull the outer filter element (2) out of the air filter case (6) and
check it for dirt.

filter element (1). Remove the inner filter element only when re-
placing it.

Replace the filter elements if they are damaged or very dirty (page 125).
Do not clean the filter element with fluids. Never operate the engine without the air filter elements.
