GENERAL DESCRIPTION
The W500/UT machine is driven by an electromagnetic clutch type needle positioning motor. The micro processor based precision controller controls needle positioning, thread trimming, thread wiping and foot lifting.
Pressing the pedal backward at the end of sewing causes the looper thread to be cut off under the needle plate. Then, the wiper takes out the needle threads from the presser foot, and the presser foot lifts. The presser foot can be moved up or down by pedal action at the start of sewing.
COMPONENTS AND MOTOR
The W500/UT machine consists of a foot lifter, motor and W500/UT machine equipped with the thread trimming mechanism. The standard motor is
MITSUBISHI LIMI-STOPZ. Various motors suitable
for the voltage and phase are provided for use as
listed in Table 1.
IDENTIFICATION
The machine is shown by the machine type, gauge and the UT device type number. Between them is a slash /.
Example: W500-01CA x 232/UT103

CAUTION (Figs. 12.13)
1. Keep the belt tension correct. Adjust it so that a 1 kg force on the center of the belt allows a
deflection of about 15 mm.
• Excessive belt tension may overload the machine
and motor.
• Insufficient belt tension may cause the belt to slip, and the needle may not stop correctly.
2.. To adjust pedal pressing force:
Pedal pressing weight can be adjusted by changing the position of hooking Tension Lever Q on Lever o
• Insufficient spring tension may cause the lever stopping position unstable and lead to malfunction.
3. To adjust pedal pressing forward force:
Loosen Nut and turn Bolt O to adjust the spring pressure.
Then, tighten Nut 0 to fix.
• Read well the guide book enclosed in the controller
and motor.
ADJUSTING POSITION OF OPERATION
DETECTOR (Fig. 14)
Press the pedal backward under the energized state, and the presser foot lifts up.
Loosen Screw 0> and slide slowly ' righfward
Operation Detector 0, and the presser foot will
drop. Turn 0 back leftward to the position for the presser foot to lift up, and tighten Screw 0.(Adjust from the rear side of the machine.)

PEDAL ACTION (Fig. 15)
Press the pedal forward and themachine runs.
• Machine speed can be freely adjusted by thepedal
pressing amount.
• After the thread has been trimmed, the presser foot can be lifted up or down by pedal action.
• Whde the machine is stopped, the handwheel can be turned freely by hand.
PRESSER FOOT LIFT SWITCH
To lift the pressr foot without trimming the thread while the machine is stopped, press Presser Foot Lift Switch (Refer to page 23, Fig. 10)
• This switch is available as option.
SELECTING NEEDLE STOP POSITION (Fig. 16)
The needle stop position can be selected by the
switch e on the controller panel.
(u.) side is Position 1, and (.—) side is Position 2.
(Refer to Table 3)
TOP SPEED OF MOTOR (Fig. 16)
The top speed of the motor is adjustable by the knob
Oon the controller panel.
• The motor speed is so set as not to rotate beyond 6,000 r.p.m. however large the motor pulley
diameter is made.

SOLENOID (UNIT) SETTING (Figs. 17,18)
1. Refer to Fig. 17 and set O and O in sequence so that the upper face of Crank O should level with the upper face of the bed horizontally. (*)
2. Solenoid stroke adjustment:
Remove Rubber Cover loosen Nut and set the
stroke to 17.9mm with Stopper 0 ,
• When loosening Nut 0, insert a round stopper bar (about 3 mm in diameter) into Stopper 0.
3. Crank position adjustment:
Set the distance between the right end face of Bracket 0 and the face ® of Crank 0 to 117.5
mm.
• Make sure that Crank 0 lightly moves when Compression Spring 0 is not fixed.

Check the dimensions of respective parts so that the upper dead point of the needle bar agrees with P
mark on the handwheel.
1. Gap A should be 1 mm under the set condition.
2. To adjust the return spring pressure, set CollarO so as to make Gap B 2 mm.
3. Set the projection of Lower Knife 0 to Size C at the left dead point of the lower knife. (Refer to Fig. 24)
4. Set the positions of advance and return of Lower Knife 0 so that the tip of the lower knife is approximately at the middle of the thickness of Looper 0 .
Adjustment should be made with Screw 0.
5. The clearance D at the cross of the blade of the
lower knife with the blade of Upper Knife 0 should be 0.5 mm, and the clearance E between the tip of the hook of the lower knife and the upper knife should be about 1 mm.
6. The clearance F between the rear end face of Plate
Spring 0 and the lower face of the second hook
of the lower knife should be zero.
• When the above parts are not exactly set at the sizes as specified, re-check the setting dimensions given on pages 33 and 34

THREAD RELEASER ADJUSTMEIMT (Figs. 29, 30) 1. Set ThreacJ Releaser Crank O so that the gap
between the side of the bed and the side of the crank should be 33 mm.
2. With Screw 0 of Crank 0 loosened, connect Lever O and Cranks O and with Screw 0 3. Adjust Lever Shaft 0 so that the gap between the
thread tension disk and the. claw of the thread releaser should be 0 ~ 0.5 mm. Then, tighten Screw 0 on Crank
4. Shaft 0 should be stopped with Screw 0 so that
the size A should be 37 mm.
• The thread releasing for each thread depends on the positional relation between Thread Guide 0
and Thread Releaser For cotton thread:
B = 6 mm, C = 7 mm, D = 8.5 mm, E = 6.5 mm, F = 9 mm
For elastic thread such as woollie threads, reduce the clearances slightly.
- NOTE;
Thread Releaser 0 (for upper spreader thread) should be set to such a position that should not be affected even when the needle thread and the looper thread are loosened.
OPERATION DETECTOR ADJUSTMENT (Fig. 31) Loosen Screw 0 and set the gap between Operation Detector 0 and Magnet 0 to 0.5 mm.
