2.Preparation
-1-
Align machine balance wheel belt groove (A)
with motor pulley belt groove (B) by moving the
motor(C) leftward or rightward. Be sure the belt is
not touch with table.
(1)Cleaning machine
Clean off the grease and dusts on the Surface of ma-
chine with gasoline and soft cloth.
(2)Inspection
Before use a thorough inspection should be done upon
the machine. Turn balance wheel slowly to see if there is
any obstacle , collision and uneven resistance between
parts. If there is , adjustment should be done before
operation.
a. The optimum tilt angle of pedal with floor is
approx 15 degree.
b. Adjust the clutch of the motor so that clutch
lever (C) and draw bar (B) run in line as Fig. 6, the
machine would have stable motion and long using.
c. The machine balance wheel should rotate
conter clockwise for normal sewing when view
from opposite side of the balance wheel. The motor
rotates in the same direction. The rotation can be
reversed by reversing (turn over 180 deg.) the plug of
the motor.
d. Adjust the tension of V-belt F by moving
the motor vertically. The proper tension of V-belt
is a slack of 10~12mm when the belt is depressed
(at the belt pan) by finger.
