NEEDLE HEAD ALIGNMENT
Insert a new set of needles, type and size as
specif ied in the description of the machine.
Needles must be inserted with the spot or
scarf to the left. Turn the handwheel in oper-
ating direction to bring needles (A,Fig. 2)
down to ensure that they are aligned in the
needle slots of the throat plate as shown.
Adjustment can be made by loosening clamp
screw (B,Fig. 2 Inset) slightly, allowing needle
bar (A) to be turned as required. Tighten
clamp screw (B).
SETTING THE NEEDLE BAR HEIGHT
The height of the needle bar is correct when the needle points are from
1/21' to 17/32" (12.7mm to 13.5mm) above the top surface of the throat
plate and the needle bar is at the top of its stroke. If adjustment is
necessary loosen needle bar clamp screw (A, Fig. 3) and move needle
bar (B) up or down. Torque screw (A) to 20 in. lbs. (2.3Nm).
CAUTION: Care should be taken not to disturb the alignment of
the needles in the throat plate when moving the
needle bar up or down.
SETTING THE LOOPER HOLDER REST
The looper holder rest must be set so it prevents the loopers, looper
holder and/or the needle guards from striking the looper thread
eyelet when the looper throw-out pin is disengaged.
Turn the handwheel in operating direction until the needles are at
their highest position. Loosen screw (A, Fig. 4) and adjust looper
holder rest (B) front to back so looper holder (C) will stop against rest (B) when the looper throw-out pin is
disengaged. Check the position of the loopers and needle guards to make sure they do not contact looper
thread eyelet (D).
NOTE:
To return the looper holder to a sewing position pull out on the looper throw-out plunger knob
and push against the looper holder frame. Release knob.
