OIL AND HYDRAULIC SYSTEM
Periodically check that there are no oil leaks
from the piping connections.
Also check the integrity of the hoses, that there
are no cuts or wear that can affect the opera-
tion of the machine.
For any replacement of the hoses, consult the
authorized and adequately equipped wor-
kshops.
WARNING
During maintenance operations, strictly avoid
environmental pollution. Dispose of waste in
accordance with local re-gulations.
5.4.1
REPLACING THE HYDRAULIC OIL
- Every 8 hours of work, check the oil level in the
tank, through the control light (5 Fig. 14). This
check must be carried out under cold condition
and the correct level must be on the center of the
indicator.
- After the first 100 hours, replace the filter cartri-
dge (4 fig. 14). The cartridge is then replaced e-
very 1000 hours or when the pressure gauge (1
fig. 14) indicates clogging of the filter.
- After 1000 hours complete replacement of the
hydraulic oil, using HYDRAULIC OIL ISO 46, or
other type with equal or superior characteristics.
Drain the oil inside the tank and drain it out of the
drain plug (6 Fig. 14) under the tank.
During this operation, put under the drain plug a
tray for the collection of the oil that will flow. Dispo-
se of waste oil in accordance with the regulations
in force.
For the introduction of the new oil:
- tighten the drain plug (6 Fig. 14);
- remove the 3 screws that secure the cover (2 Fig.
14) and remove the cover;
- unscrew the cap (3 Fig. 14) located on the top of
the filter, replace the filter cartridge (4 Fig. 14). In-
troduce the new oil from the filter through the just
replaced cartridge.
- Only use original grade filter cartridges filtration
of 25 micon and oil already filtered at least 10 mi-
cron.
5.5 CINGOLI
WARNING
• When performing maintenance with the tracked
trolley raised, it is absolutely necessary that the ma-
chine and the tracked trolley are supported and lo-
cked securely.
• If you are working on the hydraulic system, be
very careful because the oil is very hot after work.
• Ensure that the high pressure is present in the
system, not only during work but also when the
work was completed.
• The periodic maintenance intervals are for normal
working conditions. If you work in harsh conditions,
maintenance should be intensified.
