LUBRICATION OF CAB DOOR HINGES 4
(Cab specification)
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 "FUEL,
COOLANT AND LUBRICANTS (4-12)".
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.
WINDSCREEN WIPER CHECK 4
Check only after the windscreen wiper mechanism has been activated. Checking consists in detecting the faulty
cleaning of the wiper carried out with the washer in function. If after cleaning, there are scratches, it means that the
scrapping blade is deteriorated and it is necessary to replace the wiper.
NOTICE
For best functioning of the windscreen wiper mechanism, it is advisable to replace the wiper at least once
a year. Replace it more often if you work in fairly critical environmental conditions. It is also advisable to
clean the windscreen regularly to remove any dirt, grease or residue of any kind since they can hamper
the wiper regular working.
LUBRICATION 4
1. Position the machine as shown in the figure, lower the
work equipment to the ground and stop the engine.
2. Clean the grease nipple and inject the grease indicated in
the table of lubricants using the grease gun, (see "FUEL,
COOLANT AND LUBRICANTS (4-12)").
3. After greasing, remove any trace of grease.
