LUBRICATION OF CAB DOOR HINGES
(machines with cab)
Lubricate when the cab door squeaks when it is opened or
closed, or when there are oxidation traces around the shoulder
washers or their pivots.
Lubrication consists in filling the grease nipples placed on the
hinge axis with grease.
For specifications on the grease type to be used, see "4.4 FUEL,
COOLANT AND LUBRICANTS".
CAUTION
q
Inject grease until no more degraded grease is present.
q
Once lubrication is finished, remove the spilt grease and
thoroughly degrease the area.

CAB AIR FILTER CHECK AND CLEANING
(machines with cab)
WARNING
q
Wear safety goggles during the cleaning operations.
The air suction for the ventilation of the cab is protected by a filter
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 - Loosen the knobs (1), remove the external cover (2) and take
out 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 4÷5 bars.
3 - Carefully clean the filter casing, taking care to prevent any
foreign body from entering the suction duct, and reassemble
the unit.
IMPORTANT
q
If the filtering element is excessively clogged or damaged,
change it with a new one.
