3. PREPARATION AND LUBRICATION
1) Cleaning the machine
Before leaving the factory, the machine parts are coated with rust-preventive grease, which may be
hardened and contaminated by dust during storage and shipment. This grease must be removed with gasoline.
2) Examination
Though every machine is confirmed by strict inspection and test before leaving the factory, the machine
parts may be loose or deformed after long distance transportation with jolt. A thorough examination must be
performed after cleaning the machine. Turn the balance wheel to see if there is running obstruction, parts
collision, uneven resistance or abnormal noise. If these exist, adjustment must be made accordingly before run-in
operation.
3) Oiling
(1) Required amount of oil. 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 (B), oil cannot be
distributed to each part of the machine, thus causing the
parts a seizure.
(2) Replenishing
Always use only No.18 special machine oil for high
speed sewing. Be sure to replenish oil to Line (A) before
starting operation.
(3) Replacing oil
To 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.
4) Run-in operation
Run-in operation is required for a new sewing machine, or a sewing machine left out operation for a
considerable length of time.
(1) Remove Red Rubber Plugs (A) on the top of the arm
and replenish sufficient amount of oil.
(2) Lift Presser Foot (B).
(3) Run the machine at a low speed (1000-1500spm) to
check oil distributing condition through Oil Check Window
(C).
(4) Perform run-in operation at 1000-1500spm for
30minutes. After a lapse of one month of service during
which the working speed is increased gradually and the machine runs sufficiently well, the high speed 2000spm
