combustion air filter
!
Caution
Do not use gasoline or hot fluids to clean the
filter cartridge.
After cleaning the filter cartridge must be in-
spected with a torch for damage.
Dry air filter cartridges with damaged filter ele-
ment or seal must be replaced in any case.
The dry air filter element must be replaced af-
ter 3 times cleaning, but at the latest after one
year, irrespective of the operating hours.
Each cleaning interval must be marked with a
cross on the cover of the filter element.
Cleaning does not make sense if the cartridge
is covered with a sooty deposit. Use a new fil-
ter cartridge.
Incorrectly handled filter elements may be-
come ineffective because of damage (e.g.:
cracks) and cause engine damage.
When working in dusty environments the filter
service may become due considerably earlier.
This my be noticed by a drop in engine power
and black exhaust fumes.

Servicing of the dry air filter is necessary when the
yellow piston (Fig. 132) has reached the inscrip-
tion "Service", but at the latest after one year.
After completion of the filter service reset the indi-
cator back to "Zero" by pressing the button.

Carefully loosen the filter element.
The filter element is located directly on the outlet
tube, thereby providing a seal on the inside of the
filter cover. Carefully remove the filter element, in
order to reduce the released amount of dust. To
release the seal pull the filter element carefully up,
down and sideways or turn it (Fig. 134).
