SAFETY SWITCH AND ITS FUNCTION
1. Pneumatic
a. Solenoid valve (left side)1: is used to control
the presser foot lift and lower movement.
b. Solenoid valve (middle)2: is used to control the
operation ofthe lower trimmer. (Including
needle thread and lower looperthread.)
c. Solenoid valve (right side)3: is used to control
the operation of the spreader's thread trimmer
or to drive the air blower. (Please refer to the
parts list for above information.)
2. Electric
a. Electromagnet (UT534K): is to control the
operation ofthreads (upper and lower) and the
mechanism ofthread trimming (as shown
in the
parts Iist).
b. Electromagnet (UT218J): is used to control the
operation ofthe top cover thread pulling
system (as shown in the parts list).
c. Electromagnet (Ut776): is used to control the
operation oftop cover thread trimmer (as
shown
in the parts list).
3. The majorfunction ofthe safety switch is to check
and confirm the thread trimmer of needle's and
lower looper's returning to the origin. If the
trimmer is not located
on the origin, the motorwill
not function at all. (Fig.?)
Note:
(1) Please be sure to turn offthe power switch
before connecting the wires
on the
solenoid valve. If the power switch is not
turned off, please notice that the red and
blackwires do not contact. Otherwise, the
contact will cause short circuit and damage
the internal circuit (as shown
in the parts
list).
(2) The plug connecting with the motor
controlling box should be plugged fully so
that it contacts
well. This will prevent the
malfunction resulting form the loose plug.

INSTALLATION AND ADJUSTMENT
OF SYNCHRONIZER
- - -- -- - --- --
1. Press the hidden synchronizer into the long
groove of the machine head, and then tighten
the screw (3). (Fig.8)
2. Before connecting each wire or plug, please
checkthat all the electric switches are turned
off.
3. The mark (1) should be aligned with the
shorter marking line
(3) on the hand pulley (2)
when the needle bar is at its
top dead point.

OPERATION PROCESS
1. Thread on the pedal to start the machine
and sewing. (Fig.10-1)
2. When the pedal stop horizontally (Fig.
10-2), the machine stops running and the
needle bar will stop at the lower dead
point.
3. When threading the pedal backward and
holding (Fig.10-4), the needle bar moves
up and stops at the upper dead point, and
all trimming system start working.
(1) When the mechanism of the thread and
lower thread trimmer pull the thread
and the lower thread to top trimmer to
trim, the trimmed thread will be held by
the clamping mechanism.
(2) When under UTP-K and UTR-K, top cover
thread trimming mechanism trims and
clamps the top cover thread.
(3) When under UTQ-J, needle's thread will
be blown to the upside of the presser
foot by air pressure.
(4) When under UTS-K, needle's thread will be
pulled and clamped by needle's thread
pulling mechanism.
(5) Presser foot lifter.
4. Remove the material away for the next
sewing.
5. Keep the pedal in horizontal position as
shown as (Fig. 10-2), the presser foot will
put down.
6. Thread the pedal at the backward position
of (Fig. 10-3) or (Fig. 10-4) so that the
presser foot may lift.
Note:
(1) Do not put the lower trimmer to the
left thread trimming location when
there is no air pressure source
in
order to prevent damaging the lower
trimmer from turning the power
switch on.

(2) Do not put the lower trimmer to the left
thread trimming location when the
electromagnet types (UTR-K, UTS-K) are
disconnected lest the power switch
should be turned on and the lower
trimmer should be damaged.
(3) When there is no fabric under the
presser foot, do not operate the auto
trimming system.
