such as eye guard, finger guard, pulley cover, etc.

2. Never bring your hands under the needle while running the

machine.

3.A clutch motor keeps on running for a while after the power is

turned off. Therefore, be careful even after the power is turned

off as the machine could start running by pressing the machine

treadle.

4. To prevent accidents, never bring any part of your fingers,

hair and clothes near the machine pulley, V belt, motor pulley,

thread take-up and needle bar. Also never leave scissors,

tweezers, tools, etc. around these areas.

⑦Maintenance, Check, Repair

1.Well trained people should perform maintenance, check and

repair of the machine after studying these precautions and the

instruction manual carefully.

2. If it is necessary to lay the machine backward for

maintenance, check and repair, always turn off the power, unplug

the machine and press the treadle to make sure that the machine

dose not operate before beginning any of the procedures.

3. Before installing/removing the V belt, always turn off the

power, unplug the machine and press the treadle to make sure

the machine does not operate.

4.Carry out daily maintenance work and periodical inspections

properly by following these precautions and the instruction

manual.

6.Protectors for safety

This chapter describes each protector for safety. Therefore, read

and study the following carefully.

UTION

Protectors for safety

(1) Eye guard

Never leave the eye guard open.

For the safety of eyes, do not operate the machine with the eye

guard open. The eye guard will prevent any pieces of the broken

needle from getting into your eyes if the needle should break during

sewing.

(2) Finger guard

Never insert any of your fingers.

To prevent the needle that moves up and down from contacting any

of your body, the finger guard is installed close to the needle.

However, there is clearance above the finger guard for easy

threading. Be careful that the needle may penetrate any of your

fingers if you insert it into this clearance.

(3) Pulley cover

Never remove.

The machine pulley and V belt are covered with the pulley cover.

The machine pulley and the V belt rotate at high speed during

sewing. To prevent accidents, operate the machine with the pulley

cover installed in place.

(4) Pulley

Check the direction in which the machine pulley rotates.

It should rotate clockwise as seen from the pulley.

(5) Presser foot

Never insert any of your fingers.

There is a clearance of more than 5mm between the top

surface of the needle plate and the presser foot.

Be careful that none of your fingers are caught in this clearance.

Never insert any of your fingers under the presser foot when raising

the presser foot with the knee switch or automatically raising it with

the treadle.

(6)Front cover

Never leave the front cover open.

The looper travels left to right while drawing an arc as seen from the

front of the machine. To prevent the looper from contacting any

part of your body, be sure to operate the machine with the front

cover closed securely.

(7) Side cover

Never leave the side cover open.

The looper travels left to right while drawing an arc as seen from the

front of the machine. To prevent the looper from contacting any of

your body, be sure to operate the machine with the side cover

closed securely.

(8) Sliding plate

Never leave the sliding plate open.

The looper thread take-up rotates in order to supply the required

amount of looper thread during sewing. To prevent the looper

thread take-up from contacting any of your body, be sure to operate

the machine with the sliding plate closed securely.

Assembling the machine rest board

Assemble the components comprising the machine rest board by

referring to the illustration below. Be sure to secure all rods, nuts

and bolts firmly with no shake.

Sewing machine installation

UTION

Always turn off the power, unplug the machine and then well-

qualified technicians should install the machine.

deflection can be obtained by pressing the center of the belt

(see the illustration).

Installing the belt cover

UTION

Always turn off the power, unplug the machine and then well-

qualified technicians should install the belt cover.

Install belt cover 1 on the machine with screws 2.

machine table with wood screws 4.

Operating direction of the machine pulley

The machine pulley rotates clockwise as seen from the end of the

machine pulley.
