If the main filter is to be cleaned, compressed air at
max. 5 bar (72 psi) pressure should be used. Blow up
and down along the paper creases on the inside of the
filter.
Hold the nozzle at least 2–3 cm (0.8-1.2 in) away from
the paper creases so that the paper does not tear un-
der the pressure of air.
Use protective goggles when working with
compressed air.
Wipe the inside of the cover (2) and filter housing (5).
Check that the hose clamps between the filter
housing and inlet hose are tightened and that
they do not leak. Check the entire length of the
hose all the way to the engine.
Once the main filter has been cleaned a maxi-
mum of 5 times, it must be replaced.
