Check and Restore Oil Level in the Hydraulic Control Unit

Operate the distributor lever to “closing manual operation”.

Figure 27 

 

Move the actuator into his “fail to close” position.

Unscrew the dipstick (1).

Check that the oil level into the tank (4) is in correspondence of the “MAX LEVEL” notch of 
the dipstick.

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 (refer to Table 12) if in the tank the oil level is BELOW  THE MINIMUM  
(Figure 26) until to reach the optimal (MAXIMUM) oil level.

• 

Operate the distributor lever to “Remote” position.
