Cleaning primary filter

Mechanical cleaning
1 Carefully tap the end of the primary filter against a soft and
clean surface.
NOTE : Do not tap against a hard object.
Cleaning with compressed air
1 Use clean and dry compressed air with a max. pressure of 500
kPa (5 bar) (73 psi). Do not hold the nozzle closer than
3~5 cm(1~2 in).
2 Blow the filter clean from the inside along the folds.
Checking filter
1 Check the filter with the aid of a lamp.
2 If there is the smallest hole, scratch, crack or other damage,
the filter must be discarded.
NOTE : To discover damage more easily, this check should be
made in a darkened room.

Changing primary filter

Press with both thumbs on primary filter (B) at the same time as
you pull it out. This is to prevent the secondary filter from coming
out together with the primary filter.

Secondary filter

Changing secondary filter
The secondary filter (C) works as a protective filter in case the pri-
A
mary filter should be damaged. If the filter indicator lamp remains
ON even though the primary filter has been replaced or cleaned,
this indicates that the secondary filter has become clogged.
NOTE : The secondary filter should then be replaced - never
cleaned.
Replace the secondary filter when the primary filter is replaced,
Never remove the secondary filter unless it is to be replaced.
The secondary filter should be removed carefully and with preci-
sion so that no impurities enter the engine. Carefully check that the
new secondary filter is correctly installed.
