IMPORTANTE
The air filtering system consists of a primary filtering
q
element with considerable capacity and of a secondary
cartridge that ensures additional safety protection. The
primary element can be cleaned with compressed air, while
the safety cartridge can only be changed.
The filter must be cleaned when the clogging warning light
q
(A) positioned on the side dashboard comes on or flashes.
To reach the air filter lift the loader arm, engage the mechanical
safety lock and open the engine hood (see "3.5.1 ENGINE
HOOD").
To clean the primary element, proceed as follows:
1 - Release the safety retainer (1), moving it toward the outside.
2 - Turn the cover (2) counterclockwise by approximately 12.5°.
3 - Lift the cover (2) and extract the filtering element (3).
4 - Slightly strike the filtering element (3) on the palm of your
hand, in such a way as to remove the dust, and blow
compressed air on the inner surface, keeping the air jet at a
distance of approximately 15 cm and taking care to prevent
the pressure from exceeding 4-5 bars.
5 - After the cleaning operations, inspect the filtering surface for
damage by introducing a lamp into the cartridge and carefully
check the gaskets of the front seals. If the cartridge is
damaged, replace it.
6 - Carefully clean the inside of the filter housing (4), taking care
to prevent foreign bodies from getting into the suction duct.
7 - Put back the filtering element (3), making sure that it fits
perfectly in its seat.
