the protection on the motor controller or belt will take over and the spool will again take too long
to stop.
*Note: A visual check may be required to confirm whether it is the clutch that is slipping or whether it
is the motor controller or belt that is automatically adjusting in an overload situation. *
•
Check that the clutch is adjusted properly with the following procedure:

Physical Check

•
With no power being applied to the reel, grip the edge of the spool plate and apply full upward force,
making sure that you are lifting with your legs and not your back.
•
You should be able to cause the clutch to just slip with full lifting force.
•
If the clutch does not slip or slips too easily, refer to the "torque adjust procedure", below.

Torque Adjust Procedure

•
Insure that the adjusting nut is in a finger tight position.
•
If the adjustment nut is tighter than finger tight, loosen and complete previous step.
•
Match mark the adjusting nut with the hub. Using a torque wrench tighten the adjusting nut to
90ft*lb.
After the break-away torque is set, bend the tabs of the lock washer over the hex flats of the adjusting
nut.
*Note: The torque limiter clutch nut requires a reasonable amount of force to adjust. Use a torque
wrench that provides you with at least 18" of leverage. *

Run-in Procedure

•
If the torque has been taken apart and reassembled or friction disks have been changed, it is
recommended that the clutch be "run in" by "slipping" the center member (sprocket).
•
Insure that the adjusting nut is in a finger tight position.
•
Match mark the adjusting nut and hub. Advance the adjusting nut ¼ turn from finger tight.
•
Slip the torque limiter sprocket for 8 minutes at full RPM.
•
Refer back to the "Torque adjust procedure" for final
readjustment.
