ment panel lights at full engine revs.

To clean the main filter, blow up and down along the
paper pleats with compressed air at maximum 5 bar
(72 psi) pressure.
Hold the nozzle at least 2–3 cm (0.8-1.2 in) from the
paper pleats to avoid tearing the paper.
Wear 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 suction hose are tight and that the
hoses are intact. Inspect all hoses all the way
to the engine.
Change the main filter at the latest after 5
cleanings.
