5.3 SERVICING THE MOTOR
• Motor
Under normal conditions the motor is practically service-
free. Every 2
1
/
years the bearings are to be inspected,
2
cleaned and repacked with grease. We recommend K 3 N,
KL 3 N, DIN 51825/DIN 51502.
• Disc brake
Service to the disc brake is reduced to checking and
adjusting the brake air gap.
• The disc brake air gap δ should be between 0,2 and
0,4 mm. To reduce the air gap the brake ventilator must be
moved axially along the shaft towards the motor. Place a
suitable bush over the shaft and, using a screw, press the
ventilator onto the shaft until the required measurement is
achieved. Compensate the space between ventilator hub
and the circlip on the motor shaft with spacer washers.
Achtung: Do not allow the brake friction pads to come into
contact with lubricant or similar.

5.4 ADJUSTING THE SLIP CLUTCH
The factory setting of the slip clutch is 110% +/- 10% of the
rated capacity.The adjustment can be verified by lifting a
load of this value. If the clutch slips with a rated capacity
load it can be adjusted as follows (see Fig. 13):
• Remove the cover.
• Increase the clutch friction by tightening the nut (35) in a
clockwise direction.
• Verify the adjustment by lifting a test load.
5.5 ADJUSTMENT OF LIMIT SWITCH (optional equipment)
To adjust the limit switch remove the limit switch protective
cover. Operate the electric winch until it reaches the desired
position.Loosen the adjustment locking screw in the centre
of the cam block (see Fig. 11). Rotate the adjustment screw
1 or 2 until the cam operates the microswitch. Tighten the
adjustment locking screw.Operate the electric winch to the
second end position. Loosen the adjustment locking screw
once again and rotate the other adjustment screw until the
cam operates the microswitch. When the adjustment has
been completed refit the limit switch protective cover.
