Adjusting Gear Lash:
The lash, spacing between two adjacent gears teeth, is adjustable. To adjust the lash, slightly
loosen but do not remove the four lash adjustment screws in figure 13.4. The screws should be
snug but loose enough to allow the whole aluminum hook housing to move if lightly tapped with
a rubber mallet.
Figure 13.4 Gear drive assembly – lash adjustment screws
Tap the housing up to increase lash or tap the housing down to reduce lash. Too much lash will
cause the hook to wiggle excessively and timing will be sloppy. Not enough lash will cause the
gears to whine and will make the machine difficult to turn.
Make sure the needle is centered in the needle plate hole before re-tightening the lash adjustment
screws. When proper lash is achieved, install the guard plate into the machine base.
