Check of Oil Level Into the Oil Tank
(See the attached sectional drawings).
During the actuator operation the oil tank has to be closed (not in connection with the
atmosphere). Then to avoid cavitation it is necessary to proceed as follows for the check of
oil level into the tank:
•
Unscrew the dipstick (item 1).
•
Move the actuator to open position.
•
Check that the oil level into the tank (item 4) is in correspondence of the
“MAX LEVEL” notch of the dipstick.
•
By leaving the dipstick unscrewed move the actuator, by the pneumatic control or
by the handpump, to the closed position.
•
Screw and tighten the dipstick.
NOTICE
For refill use oil of the same brand as the one in the Hydraulic manual override tank.
