DANGER
•
Always wear safety goggles during the cleaning opera-
tions.
The air suction for the ventilation of the cab is protected by a fil-
ter positioned on the right side of the cab.
This filter blocks all the impurities contained in the air and must
be cleaned whenever a decrease in air circulation is observed.
The filter can be reached from the outside of the cab. To clean
the filtering element, proceed as follows:
1 - Remove the screws (1), remove the external protection (2)
and extract the filtering element (3).
2 - Hit the element slightly on the palm of your hand to eliminate
the dust and blow compressed air on its surfaces, keeping
the jet at a distance of about 15 cm and making sure that the
pressure does not exceed 45 bars.
3 - Carefully clean the filter casing, taking care to prevent any
foreign body from entering the suction duct, and reassemble
the unit.
