6.3 Emergency manoeuvre with hand pump
The following procedure enables the air inside the
hand pump to be eliminated.
If there are difficulties in priming the hand pump,
shut off the main stopcock, use an Allen key (hex
key) CH5 to loosen the screw in Figure 8 and
actuate the lever of the hand pump until oil leaves
the seat of the screw.
Now tighten the screw.

6.4 Leaks inside the valves unit
Follow this procedure to check valves seal:
 Wait for the oil to cool down to ambient
temperature
 Shut off the ball valve, start up the motor by
simulating an ascent and check pressure on the
gauge
 If there are no leaks in the valve, after the motor
is switched off the pressure remains constant or
falls slowly by a few bar over several minutes,
and tends to stabilize.
 If there are pressure losses it descends rapidly
and continues to descend
 The following valve elements are subject to
possible leaks:
EM: Emergency valve
EVD: Descent solenoid valve
VBP: Guided stop valve
PM: Hand pump
6.5 Replacing VBP valve seal
To check valves seal, proceed as follows:
• To access the VBP valve piston, remove the
hand pump, if present (Figure 9)
• Remove the VBP valve spring and remove the
VBP valve completely
• Loosen the screw that keeps the two parts of
the piston together, replace the seal of the VBP
• Refit the piston by tightening the screw that
holds together the two parts of the piston
