Hook Gear Backlash
1. Hold the hook race with your hand and
wiggle it left and right. The hook race should
have about .8mm of backlash, or ‘play’. Check
it in three different spots by turning the hand
wheel so the hook race turns 1/3 of the way
each time.
2. If an adjustment is needed, locate and
loosen (with a 2mm hex tool) the hex set screw
that holds the lower shaft eccentric bushing in
place.
3. Using a small flathead screwdriver, move
the bushing either up or down. Moving the
bushing up will give the hook more backlash,
or play, and down will give it less backlash.
Lightly tighten the hex screw and recheck hook
backlash. If the proper adjustment is made,
tighten the screw.
* Do not move the bushing or shaft to the
left or right.
