4.8.1.2 Instructions for adjusting descent of the hexagonal shaft
On models with pneumatic movement of the hexagonal arm, in order to adjust the descent speed, please follow the
instructions listed below (see fig.N):
a) Regulators A and D are pre-calibrated at the warehouse.
b) To modify the descent speed of the tool shaft, please follow the instructions listed below:
• Unscrew nut C
• Press and release the pushbutton placed on the handle repeatedly in order to move the hexagonal shaft
downward and upward and set the speed through nut D so that the descent of the hexagon is slower than
the rising or equal.
To slow the descent, rotate nut D anticlockwise.
To speed the descent, rotate nut D clockwise.
c) When regulation is done, lock the arm in an intermediate position acting the button, then unlock the arm to the
rest position. Start the arm descent pressing the button and check if the speed descent is the same as previously
scheduled.
d) Screw nut C
e) To vary the tool arm rising speed, please follow the instructions listed below:
• Unscrew nut B
• Press and release the pushbutton placed on the handle repeatedly in order to move the hexagonal shaft
downward and upward and set the speed through nut A.
To slow the rising, rotate nut A anticlockwise.
