Adjusting the unwinding speed
The 55Hpro winch is equipped with a valve for adjusting the unwinding speed. With the
45Hpro winch, this is available as optional equipment.
The unwinding speed of the wire rope is adjusted according to the following procedure:

Adjusting the limit switch
The limit switch is adjusted for operation after the assembly and test. In the event of
incorrect operation, a subsequent adjustment may be required.
Before adjusting the limit switch, turn of the tractor's engine and disconnect the power
supply to the winch.
Remove the protection of the switch (6, Figure 12c). Unscrew the safety nut (7) on the limit
switch (8). Press on the sleeve (9) until it rests in its final position. Screw on the sensor (8)
until it reaches the surface of the sleeve (9). Unscrew the sensor (8) by one turn, so that
the distance between the sensor and the sleeve (9) is 1 mm.
Check the operation of the limit switch:
When the sleeve (9) is released, the sensor (8) is not active (the sensor lamp is off). Move
the sleeve (9) by 5 mm (the sensor lamp flashes). Press on the sleeve (9) until it reaches its
final position (the lamp is on).
If the sensor operates properly, fasten the cover of the sensor (6) back onto the rope
guide.
-
To increase the unwinding speed, rotate the valve
(5, Figure 12b) in the counter-clockwise direction.
-
To decrease the unwinding speed, rotate the valve
(5) in the clockwise direction.
-
If the valve (5) is turned all the way, the wire rope
stops unwinding.
