Adjusting Backlash between Hook Drive Gear and Lower Shaft Gear
• The rotary play should be 0.8 mm or less when the hook point is within the span of the feed
dog, and the gears should turn smoothly.
<To adjust>
Remove the base cover (see page 5).
Loosen the setscrews.
If the backlash is too big, turn the lower shaft bushing in the direction (B).
If the gear engagement is too tight, turn the lower shaft bushing in the direction (A).
Tighten the setscrews and attach the base cover.
NOTE:
Be sure to check and adjust the needle to hook timing and feed dog height if necessary, after
performing this adjustment.
