Check and Restore Oil Level in the Hydraulic
Manual Handpump
During the actuator operation, the oil tank has to be closed (not in connection with the
atmosphere). Then avoid cavitation it is necessary to proceed as follows for the check of
oil level into the tank:
1.
Unscrew the dipstick (1).
2.
Move the actuator into open position.
3.
Check that the oil level into the tank (4) is in correspondence of the “MAX LEVEL”
notch of the dipstick.
4.
By leaving the dipstick unscrewed move the actuator, by the pneumatic control or
by the handpump, to closed position.
5.
Screw and tighten the dipstick.
If necessary substitute or added the oil, proceeding as follow:
•
Remove the dipstick (1) from the tank cover (22).
•
Unscrew the plug (27) and the washer (9) to drain all the oil.
•
If some dirt or/and sludge is found in the oil drained from the tank, before filling
with new oil in the tank, disassemble the oil tank tube, by unscrewing the two cap
nuts (2), and clean the internal surfaces of the tank. If necessary substitute the
gaskets (21) of the tank.
•
Replace the plug (27) and the washer (9) into the plate (11) and tighten.
•
Pour the new oil into the tank through the dipstick hole (1) on the cover (22).
•
Replace the dipstick (1).
•
Add oil (Table 5) if in the tank the level is BELOW MINIMUM (Figure 19).
