5.6.5 Hydraulic pumps and motors
Before all use, visually check that there are no leaks in the fittings, flanges and piping.
The hydraulic pumps and motors do not require further maintenance. If there are
leaks, contact the After-sales Centre.
5.6.6 Hydraulic oil
Before use, visually check the hydraulic oil level through the indicator on the tank. The
level must be at the centre of the indicator. Top-up if necessary through the filling cap.
(
fig. 6.5.9
) .
ATTENTION:
the following operations must be performed with the platform in the
rest position
(outriggers completely retracted and booms closed).
Replace the hydraulic oil at least once a year or every 2000 hours. On this occasion
the hydraulic oil filters must also be replaced.
For replacement, use a suitable tank or tanks with sufficient capacity and drain out the
waste oil, loosening the drain cap under the tank. Close the drain cap and fill the tank.
Tank
capacity:
28 litres

Flow point =-30°C
ATTENTION:
do not disperse hydraulic oil in the environment during replacement.
Dispose of the oil in compliance with the Law.
5.6.7 Hydraulic oil filter
There is a filter near to the tank. At every use, check the blockage indicator on the
filter. This control must be carried out during the operational phase. If the indicator is
in the red area, the filter must be replaced.
After the first 100 hours and, successively, every 3 months or 500 hours, replace the
filter. Comply with the controls and the replacement frequencies indicated as blockage
of the filter decreases the efficiency of the machine and causes damage to the
hydraulic components.
ATTENTION:
whenever some components of the hydraulic circuit are replaced due to
serious faults such as seizure of pumps, hydraulic motors or cylinders with
the consequent introduction of large amounts of impurities, it is necessary
to repeat the filter replacement procedure from the start, as described
above.
