Checking, Cleaning, Replacing The Combustion Air Filter - Bomag BW 100 AD-4 Operating Instructions Manual

6.18 Checking, cleaning, replac-
ing the combustion air filter
Caution
!
Perform cleaning, maintenance and repair
work only with the engine shut down. Do not
start the engine after removing the filter ele-
ment.
Do not use gasoline or hot fluids to clean the
filter element.
After cleaning the filter element must be in-
spected for damage using a torch.
Air filter elements with damaged paper bellows
or seal lips must be replaced in any case.
The main filter element must be replaced after
6 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 air filter
element is covered with a sooty deposit. Use a
new filter element.
Incorrectly handled filter elements may be-
come ineffective because of damage (e.g.:
cracks) and cause engine damage.
Open the engine hood.
