set screws in pulley or bevel gear.

NEEDLE THREAD TENSION

TAKE-UP SPRING STROKE

CHECK:

The take-up spring, Fig. 19, should complete its action and be at rest against take-up spring stop as point of needle enters material.

SETTING:

To adjust the take-up spring stroke, loosen set screw, Fig. 19. Move slack thread regulator to the right to complete take-up spring action earlier (shorter stroke) or to the left to complete take-up spring action later (longer stroke). Then securely tighten set screw.

 

TAKE-UP SPRING TENSION

CHECK:

Tension on the take-up spring should be just sufficient to take up the slack of needle thread until point of needle enters material.

SETTING:

Turn tension dial to zero, remove face plate and loosen stud set screw, Fig. 20. Remove entire tension assembly from machine. Slide end of take-up spring, Fig. 20, out from groove in tension stud. Turn end of spring toward right (CLOCKWISE) to increase tension or toward left (COUNTERCLOCKWISE) to decrease tension and place it in nearest groove. Replace tension assembly, drawing take-up spring up so it rests on take-up spring stop, Fig. 19, and securely tighten set screw.
