(2) If the machine

lubricated by a drop oiler, never operate the machine before lubricating.

(3) When a new sewing machine is first turned·on, verify the rotational direction

the balance wheel with

the power on. (The balance wheel should rotate counter-clockwise when viewed from the balance wheel)

(4)

Verify

the voltage and (single

three) phase with those given on the machine nameplate.

Precautions for Operating Conditions:

Before leaving the factory, the machine

parts are coated with rust-preventive grease,

which may

hardened and contaminated by

dust during storage and shipment. This grease

must

removed with gasoline.

2) Examination

Though every machine is confirmed by

strict inspection and test before leaving the

factory, the machine parts may

loose or

deformed after long distance transportation with

jolt. A thorough examination must be performed

after cleaning the machine. Turn the balance

wheel

see

there is running obstruction,

parts collision, uneven resistance or abnormal

noise. If these exist, adjustment must

made

accordingly before run-in operation.

3) Oiling (Fig.I)

Line (A) on the oil reservoir: Max. Oil level

Line (B) on the oil reservoir: Min. Oil level

If oil level goes down under line

(2) Replenishing

Always use only No.

special machine oil

for high speed sewing. Be sure to replenish oil to

line A before starting operation.

(3) Replacing oil

replace oil, remove screw (C) to drain oil.

After completely draining off oil, clean the oil

reservoir and securely tighten screw (C), then fill

the reservoir with fresh oil.

talcing

the graduation which meets the top surface

the feed lever as

reference:

Turn the dial

direction to reduce the reverse feed

stitch length. "+2"means "normal feed stitch length is 2mm" and "-2"

means "reverse feed stitch length is 2mm".

Advert: The graduations on the dial are mere reference. So adjust

the denser stitching while actually observing the finished seam.
