TO SET NEEDLE

Turn machine until Needle Bar is at its lowest position. Adjust needle
until it projects slightly below bottom of whirl. The Needle should be set
so that the Whirl lays the thread in the barb groove of the Needle as it
revolves around the Needle, much on the order of the Looper on the
Curved Needle Stitcher. (See figure No. 2).

NEEDLE BAR FRICTION

For more friction, turn Adjusting Screw (in top of Main Head) to the right; for less friction, turn screw left.
This Friction Screw is adjusted at the factory and requires little attention. It is used to hold Needle Bar in
place when Latch is released. A few drops of oil should be placed in Oil Hole each day.
CAST-OFF FRICTION
The Cast-Off Friction is adjusted at the factory so the Cast-Off Block can be moved up and down with the
fingers without moving the Cast-Off Rod. For more friction, turn Adjusting Screw in Cast-Off Friction
Holder to right; for less friction, turn Screw to left. A few drops of oil should be placed in Oil Hole each
day.
