4.7.13.c CHANGING THE HYDRAULIC SYSTEM OIL
AND CLEANING THE SUCTION FILTER
CAUTION
•
On machines containing synthetic biodegradable hydraulic
oil type HEES, carry out the change after the first 500 hours
of operation and successively every 2000 hours, and in any
case at least once a year.
DANGER
•
Retract the bucket and arm cylinder completely, extend the
cylinders of the two-piece boom completely, lower the
bucket teeth to the ground and, after stopping the engine,
release the residual pressures from the work equipment
circuits (by operating the controls more than once) and
from the tank (by slowly loosening the filling cap).
•
Let the oil cool down until it reaches 40-45°C before carry-
ing out any maintenance operation.
•
Immediately clean any area dirty with oil.
•
Oils, filters, coolants and batteries are considered special
waste and must be collected and disposed of according to
the anti-pollution regulations in force.
1 - Rotate the upper structure by 90°, in such a way as to leave
the lower part of the hydraulic oil tank free from the tracks.
2 - Retract the bucket and arm cylinder completely, extend the cyl-
inders of the two-piece boom completely, lower the boom until
the bucket teeth touch the ground.
3 - Lower the blade to the ground.
4 - Stop the engine and release the residual pressures from the
equipment circuits by shifting the controls more than once.
5 - Open the right side cover (see “3.5.2 SIDE COVER”) and
slowly loosen the filling cap (1) to release the residual pres-
sure.
