Air cleaner – check, clean the filter insert
WARNING
When using compressed air, there is a danger of flying dirt caus-
ing injuries. Always wear protective equipment such as protec-
tive goggles and a dust mask.
NOTICE
 Dirt can get into the engine if inspection, cleaning or mainte-
nance work is carried out with the engine running; this can
cause damage to the engine. Make sure to stop the engine
before you carry out such interventions.
 If the air cleaner is not sufficiently clean, the
air cleaner cau-
tion lamp (1)
on the main screen will indicate a malfunction.
The engine power will decrease.
Design of the air cleaner
The air cleaner is made up of the air cleaner housing, the dust
eject valve, the filter insert, and the safety filter.
Required maintenance
NOTICE
Do not clean the air cleaner element before the air cleaner cau-
tion lamp (1) on the main screen lights up.
If the air cleaner caution lamp (1) lights up, the air cleaner insert
is clogged. Clean or replace it immediately.
Dirt in the safety filter indicates a damaged filter insert. In this
case, the filter insert and the safety filter need to be replaced.
