4.7.1.b CHECKING AND CLEANING THE CAB AIR
FILTER
DANGER
•
Always wear goggles while cleaning the filter.
Air suction for the ventilation of the cab is protected by means of a
filter positioned on the right side of the cab.
This filter holds all the impurities contained in the air and must be
cleaned whenever a decrease in the air circulation is noticed.
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 outer conveyor (2) and ex-
tract the filtering element (3).
2 - Slightly strike the element on the palm of your hand to elimi-
nate the dust and blow compressed air on the inner surface,
keeping the air jet at a distance of approximately 15 cm and
making sure that the pressure does not exceed 4-5 bars.
3 - Carefully clean the filter casing, taking care to avoid the intro-
duction of foreign matters in the suction duct.
4 - Put back the filtering element (3) and the outer conveyor (2).
IMPORTANT
☞
•
If the filtering element is strongly clogged or damaged, re-
place it with a new one.
