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.
4.9.1.m WINDSCREEN WIPER CHECK
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.
IMPORTANT
q
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 advis-
able to clean the windscreen regularly to remove any dirt, grease or residue of any kind since they can
hamper the wiper regular working.
4.9.1.n
BLEEDING THE HYDRAULIC SYSTEM
1.
Start the engine and let it idle for approximately 10 minutes (see "3.3.1.5 STARTING THE ENGINE").
2.
Extend all cylinders 4-5 times, stopping them at approx. 100 mm from the end of stroke.
IMPORTANT
q
If the engine runs at maximum rpm or if the cylinders are brought to the end of stroke soon after starting,
the air sucked in by the cylinders may damage the piston gaskets.
3.
Slowly make all the cylinders reach the end of stroke for 3-4 times.
