SETTINGS
1. Clutch
A properly set clutch enables optimal traction force. The clutch was factory set during the
testing of the winch, but due to friction surface wore, it eventually must be set anew.
The re-setting is not permitted within the warranty period!
Install a dynamometer on the black string. In case you do not own a dynamometer, you
can also use a spring balance with an appropriate weighing range. Once you have
installed the dynamometer (spring balance), pull the string with a force of 350 N (35 kg)
and check the position of the lever (pos. 1, figure 11). This lever can be seen in figure 11a.
Use the nut on the main shaft (pos. 8, figure 11) to regulate the position of the lever (pos.
1), until the lever is not touching the backrest. In case you tightened the nut too hard
(pos. 8, figure 11) and the lever moved away from the backrest, the necessary axial force
on the friction surface of the clutch has been reduced too much. The winch will not be
able to reach to necessary traction force and the friction surface of the clutch will be
damaged due to sliding.
2. Safety brake
Use a screw (pos. 6) and a lock nut (pos. 7, figure 11) to set the safety brake. First loosen
the lock nut and regulate the screw (pos. 6). By turning the screw clockwise, you increase
the brake force and by turning the screw anti-clockwise, you decrease the brake force.
Then tighten the lock nut which prevents the screw from becoming loose. A proper setting
means that the wire rope will not unreel from the drum automatically or too easily. This
can lead to wire rope damage when you release the brake and start unreeling the wire
rope. The safety brake is set properly when the wire rope can be unreeld without too
much effort. In case you are pulling the rope up a slope, it is possible to additionally
relieve the brake so that the pulling of the rope is easier. But after you finish the work, the
safety brake must be returned to its original position (as describe above).
