Air filter
If control light (7) in the instrument panel lights up the filter
must be immediately cleaned or, if necessary, replaced.
Check the air lines (filter - engine) for leaks during every main-
tenance. Replace defective parts and tighten loose hose
clamps.
IMPORTANT! The air filter maintenance intervals depend on
the amount of dust in the air and can therefore not be deter-
mined precisely. Under extremely dusty conditions daily
cleaning may be required.
Cleaning the dust valve
Clean the dust valve every 10 operating hours.
1 Empty the dust valve (9.1) by squeezing the slot together.
2 Remove possible dust deposits by squeezing the upper part of
the valve.
Cleaning the air filter cartridge
Clean the air filter cartridge every 250 hours.
1 Open the locking hooks for the housing lid and remove the filter
cartridge (9.2).
2 Bang the filter cartridge several times with the front face verti-
cally against the palm of your hand or against a flat and soft sur-
face.
NOTE! Avoid damaging or denting of the front face of the cart-
ridge.
3 Blow the cartridge out with dry compressed air (pressure not
higher than 5 bar) from inside under an oblique angle, until the
out flowing air is free of dust.
4 Then inspect the filter with a lamp from inside to outside for pos-
sible cracks.
NOTE! Use only genuine filter cartridges. Non-genuinefilters
do not fit and cause danger to the engine!
Replacing the air filter cartridge
Air filter change interval every 500 operatinghours, but at
least once every year.
1 Open the locking hooks for the housing lid and remove the filter
cartridge (9.2).
2 Replace the filter cartridge and close the housing lid with the
locking hooks.
Auxiliary filter cartridge (option)

IMPORTANT! The safety cartridge (9.3) must not be cleaned.
The engine must not be operated just with the safety cart-
ridge installed.
WARNING!
Do not try to clean the filter cartridge by banging it against
a hard object.
