HOW TO RE-SET THE SAFETY CLUTCH MECHANISM
The sewing hook and it's mechanism are protected by a safety clutch. In case the hook
gets jammed with thread or other foreign matter, the safety device disengages the driving
belt, stops sewing, and thus prevents the machine from getting damaged. If it should
become necessary to re-engage the safety clutch, depress the button (E, Fig. 2) in the bed
plate, at the same time, turn the handwheel away from you until the locking mechanism re-
engages the drive shaft beneath the bed of the machine, open the slide plate above the hook
and rock handwheel back and forth to remove any foreign matter which may have lodged in
the hook.
Do not use any sharp-edged tools, etc. lest the hook be damaged.

REPLACEMENT OF THE TIMING BELT

1. INSERTING THE BELT
Turn the balance wheel toward you until the take-up lever reaches to its highest point.
Turn the lower shaft (1) until the arrow mark on the lower shaft bearing collar (2) meets
with another arrow mark on the timing plate (3). Insert a new tilling belt into the belt pulley
at this position.
2. REMOVING THE TIMING BELT
Remove the arm top cover (F, Fig. 2) and remove the timming belt from the belt pulley,
loosen the collar set screw (1, Fig. 15).
Loosen the two set screws (G, Fig. 2) for the hand pulley and remove the hand wheel
adjusting screw (1, Fig. 14), draw Out the hand wheel from the arm shaft.
Loosen the arm shaft rear bushing set screw (2, Fig. 15), pull out the rear bushing (3,
Fig. 15) from the arm hole.
In case of the machine with reverse stitch mechanism, draw out the reverse lever (4, Fig.
15) with its shaft.
Removing or inserting the timing belt is made through the hole drawn out the rear
busing.
