TRIDGE
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
☞
•
If the machine works in dusty places, this cleaning opera-
tion must be performed more frequently.
In any case, check the cartridge for any clogging every 50
hours of operation.
The air cleaner (1) can be reached after opening the engine
hood (See “3.5.1 ENGINE HOOD”).
To clean the element, proceed as follows:
a - Remove the coupling (2) and release the filter from its sup-
port.
b - Remove the couplings (3) and the cover (4) and extract the
filtering element (5).
c - Hit the element slightly on the palm of your hand to eliminate
the dust and blow compressed air on the inner surface, keep-
ing the jet at a distance of about 15 cm and making sure that
the pressure does not exceed 4÷5 bars.
d - Carefully clean the filter clogging cover (4) and the filter cas-
ing, taking care to prevent any foreign body from entering the
suction duct and reassemble the unit, making sure that the
ejector positioned on the cover is directed downwards.
IMPORTANT
☞
•
Change the filtering element after 5 cleaning operations or
after one year.
