SETTING THE LOOPER TRAVEL
To adjust the looper travel remove the top front cover and the end
cover. Loosen left-handed locknut (A, Fig. 7) and turn screw (B)
clockwise to decrease the looper travel or counterclockwise to
increase the looper travel. Tighten locknut (A) and recheck setting.
NOTE: After setting the looper travel the machine must be checked
for synchronization.
TIMING THE NEEDLES TO THE LOOPER
To visually check the timing of the needles to the looper, turn the handwheel in operating direction until the
needle bar has reached its lowest position and has risen 5/32" (4.0mm). At this time the looper point should
appear at the same relative position to the needles whether rotation of handwheel is clockwise or
counterclockwise.
INSTRUCTIONS FOR USING
SYNCHRONIZING GAUGE 21227CG
Turn the handwheel until the needle bar is at its lowest point. Loosen
presser bar regulating screw (A, Fig. 8) and insert needle bar setting
block (B) under the head of the screw (A) with stop screw (C) above
needle bar (D). Tighten screw (A).
The long portion of the looper clamp and height gauge (E, Fig. 8) laid
on its side is the 5/32" (4.0mm) gauge used to set the distance
between stop screw (C) and the top of the needle bar (D) at its lowest
position. Tighten nut (F) to clamp stop screw (C) into place.
NOTE: If needle height has already been set attach gauge 21227FD
(G, Fig. 8A) to the top of the needle bar to obtain the 5/32" (4.0 mm)
setting.
