1.5 - Balancing
Correct balancing is essential if the boom gate is going to work prop-
erly.
Rectify balancing only when the bar is mounted and with all the ac-
cessories installed (if any).
Manually release the boom (fig. 9 - 10) and adjust the spring tie-rod
(fig. 11). The boom is properly balanced when it stays at an angle of
45° without falling or rising. If you are using a very short bar without
any accessories, the power of the spring will be far too strong: in this
case connect the spring to the 2nd hole of the gearmotor output
lever, fig. 12.

Slowing down is electronically carried out on the control unit (see
instructions enclosed).
The point at which the bar starts slowing down can be adjusted sep-
arately in opening and closing via the two eccentrics (fig. 13).

For optimal slowing down, adjust the two stop shock absorbers with
a 19 mm wrench (fig. 14).
