ADJUSTING THE ROLLER CHAIN

TIGHTNESS

Roller chains tightness adjustment is carried out by
moving the chain tightener. See fig. 17.
1. Loosen the two bolts holding the chain tightener
(11/16" or 17 mm wrench).
2. Adjust the chain tightness by moving the chain
tightener towards or away from center.
3. Tighten the nuts.
4. Check that the chain tightener runs on the rollers.
NOTE! Do not over tighten the chain.

ADJUSTING THE DRUM BRAKE

Adjust the drum brake so that it slows down the drum
slightly while pulling out the rope. This will reduce risk
of tangling and backlash.
• To increase the braking effect tighten the adjust-
ment bolt. See fig 18. To decrease the braking ef-
fect loosen the adjustment bolt.
