HYDROSTATIC AND HYDRAULIC SYSTEM MAINTENANCE
1) Intake and return filter cartridge replace-
ment
This cartridge must be replaced:
a) every 800 hours,
b) or every two years,
c) at each emptying.
2) Circuit filling -- emptying
Drain the circuit every 800 hours and at least every
two campaigns.
Comply with the following precautions:
a) fill the tank completely with the recommended
oil at the end of the campaign, to avoid any con-
densate build--up during the intermediate sea-
son. The filling must be made by a pump
through the return fast fitting that filters oil dur-
ing filling itself or through a suitable fitting.
b) Before the following campaign and, compulsor-
ily, before starting the thermal engine, empty
the tank partially to ensure a perfect oil settling.
c) Check the oil level in the reservoir.
WARNING:
when topping oil up, use
the same type used for the initial filling.
When draining oil, work with great care and cleanli-
ness. Clean the drain and filling holes, before disas-
sembling them, by a jet of compressed air or a clean
brush and oil, so that no foreign impurities or matters
enter the circuit.
Remove the drain nut under the reservoir. Only the
reservoir must be emptied.
During this operation, replace the intake and return
filter cartridge, too.
DANGER:
bleed the shaking pump
(see corresponding diagram in section 35).
