ADJUSTMENT OF THE UPWARD AND DOWNWARD DECELERATION
For a correct and safe adjustment of the upward and
downward deceleration time please refer to the following
procedure:
1. Loose the counter-nut of the screw (3).
2. Tighten the screw (3 CW) to increase the deceleration
time (C-D upward, G-H downward). Loose (CCW) the
screw to reduce it.
3. Adjusted the time, tighten the counter-nut of the screw
(3).
4. The up- and downward deceleration time adjustment is
done.
NOTE
The maximum deceleration is obtained when the
deceleration adjustment screw (3) is completely
open.

ADJUSTMENT OF THE PRESSURE ON THE RAM ON VSMA
NOTE
Applicable only if 2:1 system
To adjust the pressure on the ram on VSMA:
1. Open the pressure gauge tap (6)
2. Close the shut-off valve (R/S). [the lever must be at 90 °
with respect to the pipe directed to the piston]
3. Press the manual lowering push button (ML) until the
pressure decrease stops.
4. Verify on the pressure gauge (MAN) that the pressure is
about 5 bar.
If the pressure is 5 bar go to point 6, if it is lower than 5
bar or the ram do not move down, go to point 5.
5. Adjustment
-
Open the shut-off valve (R/S).
-
Loose and remove the protection cap of the adjusting ram pressure screw (7)
-
Loose the locknut of the screw (7). Screw by 1 turn the screw (7). Tighten the locknut of the screw (7).
-
Close the shut-off valve (R/S).
-
Press the manual lowering push button (ML) until the pressure decrease stops.
-
Repeat this procedure until pressure obtained on the pressure gauge (MAN) is about 5 bar.
-
Mount and tighten the protection cap of the adjusting ram pressure screw (7) and go to point 6.
6. Reduce the pressure on the pressure gauge (MAN) by pressing the VMD or the push-button (ML).
7. Close the pressure gauge tap (6).
8. Open the shut-off valve (R/S).
