CHECKING, CLEANING OR CHANGING
THE AIR CLEANER CARTRIDGE
DANGER
•
Remove the air cleaner only after stopping the engine and
do not start the engine if the air cleaner is open.
•
Always wear safety goggles during the cleaning opera-
tions.
IMPORTANT
☞
•
The air filtering system consists of a primary filtering ele-
ment with considerable capacity and of a secondary car-
tridge that ensures additional safety protection.
The primary element can be cleaned with compressed air,
while the cartridge must be changed.
•
The filter must be cleaned when the clogging warning
light (A) positioned on the side dashboard comes on or
flashes.
The air cleaner can be reached after raising the loader arm, en-
gaging the mechanical safety lock and opening the engine hood
(See “3.5.1 ENGINE HOOD”).
To clean the primary element, proceed as follows:
1 - Release the safety lock (1), moving it toward the outside.
2 - Rotate the cover (2) anticlockwise 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 com-
pressed air on the inner surface, keeping the air jet at a dis-
tance of approximately 15 cm and taking care to prevent the
pressure from exceeding 4-5 bars.
5 - Carefully clean the inside of the filter case (4), taking care to
prevent foreign bodies from getting into the suction duct.
6 - Put back the filtering element (3), making sure that it is per-
fectly housed in its seat.
7 - Put back the cover (2), rotating it clockwise by approximately
12.5°. Make sure that the cover (2) is perfectly locked and
make sure that the ejector (5) is positioned vertically on the
lower part.
8 - Once the whole has been assembled, push the safety lock
(1) towards the inside.
IMPORTANT
☞
•
If the clogging warning light comes on after the starting of
the engine, it is necessary to change the primary filtering
element and the safety cartridge.
•
Change the primary filtering element after 6 cleaning op-
erations or after one year.
Every time the primary filtering element is replaced, the
safety cartridge must be replaced, too.
