Willcox & Gibbs W562 User Manual

SYNCHRONIZING NEEDLE BAR AND LOOPER
The looper should be at the right dead point
when the needle bar is in the lowest position.
The looper should begin to move as the needle
bar begins to rise. The looper should pass
behind, and then return in front of the needles
at exactly the same level.
To adjust:
1. Remove the arm cover.
2. Loosen 4 Screws ®, turn Handwheel ® and
shift the position of Upper Belt Gear
• To advance the looper timing against the
needle, shift the position in the (+) direction.
• To retard the looper timing against the
needle, shift the position in the (—) direction.
- Note:
The looper holder is at the right dead point
when the needle bar is in its lowest position.
Synchronization between the needle bar and
the looper may change when the looper
avoiding motion is adjusted.
In this case, adjust as above.

needles to the right. Adjust the looper avoiding
motion according to the needle size.
