8.2.10 Maintaining/replacing the air filter
NOTE
Maintenance of the filter cartridge is necessary
when either the red range is visible in the mainte-
nance indicator (8-31/arrow) or after 12 months,
whichever is sooner.
(1) Open the motor hood.
(2) Unscrew the two upper wing nuts on the maintenance
grille (8-32/arrows). Push the grille outward at the upper
section and lift it out.
(3) Loosen the two retaining clamps of the air filter lid
(8-33/1) and remove the air filter lid.
(4) Pull out the filter cartridge (8-33/2) by carefully turning
it back and forth.
(5) Clean the filter cartridge.
CAUTION
- For cleaning, use a compressed air gun to which
a pipe (angled at 90°) has been attached. The
pipe must be sufficiently long to reach the
bottom of the cartridge. Use dry compressed air
of no more than 5 bar to blow out the car
tridge by moving the pipe back and forth in the
interior of the cartridge. Cleaning can be
stopped when dust formation ceases.
- Do not use petrol or hot liquids for cleaning.
(6) Use a hand-held lamp to check the cartridge paper
and the rubber gasket of the filter cartridge for damage.
If the cartridge or the gasket is damaged, replace the
cartridge.
(7) Carefully insert the filter cartridge.
(8) Install the air filter lid on the filter housing in such a way
that the direction arrow in the marking “
OBEN-TOP ” points
upwards. This ensures that the dust removal valve faces
downwards.
(9) When the indicator field becomes red (8-31/arrow),
push the reset button. The field becomes clear.
(10) Screw the maintenance plate (8-32/arrows) back on.
CAUTION
Check all connection pipes and hoses of the air filter
system for damage before starting the engine.
