Use compressed air at a maximum pressure of 5 bar
(72 psi) to clean the main filter by blowing up and down
along the inside of the pleated paper filter.
Hold the air nozzle at least 2 to 3 cm (0.8-1.2 in) from
the paper pleats so as not to tear the paper.
Use protective goggles when working with
compressed air.
Wipe the inside of the cover (2) and the filter housing (5).
Ensure that the hose clips between the filter
housing and the intake hose are tightened and
that the hoses are intact. Inspect the entire
hose system all the way to the engine.
Change the main filter after cleaning it five
times.
Replace the backup filter with a new one after cleaning
or changing the main filter five times. The backup filter
cannot be cleaned and reused.
To change the backup filter (4), pull out the used filter
from its holder, insert a new filter and reassemble the
air cleaner in the reverse order.
