Maintenance

Checking and cleaning the air filter

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



Open the engine hood (page 74).



Open the clips (2) and remove the cover (1).



Pull the outer filter element (3) out of the air filter case and
check it for dirt.



Clean the air filter case and cover without removing the
inner filter element (4). Remove the inner filter element only
when replacing it.



Renew the outer filter element if it is damaged or too much
dust has accumulated on it.

Do not clean the filter element with fluids. Never operate the engine without the air filter ele-
ments.



Clean the outer filter element with compressed air (max.
5 bar) from the inside out without damaging the filter ele-
ment. Wear eye protection for this service.



Insert the outer air filter element and the cover with the TOP
mark up.



Close the engine hood.

Replacing the fuel filter



Open the engine hood (page 74).



Set the cock (1) horizontal to the "C" position.

Place a cleaning cloth under the fuel filter to pre-
vent fuel from spilling on the ground.
