– Measure the slip torque in both directions of rotation and, if necessary, adjust it
via the slotted nut.
•
If you adjust the slip torque using a spanner wrench, you can only roughly set the
slip torque. In this case, determine the value "Z" that must be set to achieve the re-
quired slip torque based on the following table (see
The value "Z" is:
– For AR 71 – 115 drives, the number of cams of the lock washer starting from
the mark.
– For AR 132 – 195 drives, the number of slots of the slotted nut starting from the
mark.
11. Secure the slotted nut either with a lock washer or a clamping screw, depending
on the adapter type.
12. Reassemble the drive in opposite order.
