PRECAUTIONS BEFORE STARTING OPERATION
1.
Safety precautions
1) When turning the power on, keep your hands and fingers away from the area around/under the
needle and the area around the pulley.
2) Power must be turned off when the machine is not used, or when the operator leaves his/her seat.
3) The power must be turned off before tilting the machine head, installing or removing the “V” belt,
adjusting the machine, or when replacing.
4) Avoid placing fingers, hairs, bars etc. near the pulley, “V” belt, bobbin winder pulley, or motor
when the machine is operation. Injury could result.
5) Do not insert fingers into the thread take-up cover, under/round the needle, or pulley when the
machine is in operation.
6) If a belt cover, finger guard, and/or eye guard are installed, do not operate the machine without
these safety devices.
Precaution before Starting Operation
1) If the machine’s oil pan has an oil sump, never operate the machine before filling it.
2) If the machine is 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 of the pulley with
the power on. (the pulley should rotate counterclockwise when viewed from the pulley.)
4) Verify the voltage and (single or three) phase with those given on the motor nameplate.
Precaution for Operating Conditions |
1) Avoid using the machine at abnormally high temperature (35°C or higher) or low temperature (5
‘Cor lower). Otherwise, machine failure may result.
2) Avoid using the machine in dusty conditions.
3) Avoid using the machine in areas where too much electrical noise, resulted from the
high-frequency welder and others, is generated.

1) Connection to Power Supply
When connecting the power supply connector to the control box, the connector should be completely
plugged in the proper receptacle after confirmi
ng the connector type and matching direction.
A. Incase of three-phase electrical power system, the “U” phase should be connected to the red lead,
the “V” phase to the white lead, and the “W” phase to the black lead. The motor rotary direction
depends, however, upon the setting of the internal switch in the control box as described in
Paragraph 1-(3)
CAUTION: The green wire must be connected to the ground terminal in arder to ground
the motor properly.
В. The appropriate power fuse capacity is as follows. Power supply 200V-240V: 10A
100V-120V: 15A
2) Lamp Leads
A. When installing the illuminating lamp(6V,
15-20W), The connecting wire is attached on the
back of the Control box. It should be
removed and connected by
removing the insulating tube
from the wire and stripping
properly. The wire connections
should be, then, insulated by

CAUTION: The power switch must be Turned off before connecting the lamp.
When the illuminating lamp is not used, the end of the lamp leads must be insulated as (a) or (b) as
shown in the figure on right side. If a short circuit occurs failing to insulate, the transformer in the
control box will be possibly burned out.
CAUTION: The illuminating lamp must not be connected with any heater, such as a foot
warmer and others, in parallel. Otherwise, the load capacity will be exceeded.
It may cause transformer winding burned out.
Rotary direction
It is possible to change the rotary direction of the motor by removing the rubber cap from the
bottom left side of the front cover on the control box, and push the internal direction selector
switch. The built-in lamp in the internal switch is off when the motor is rotating counterclockwise as
facing to the motor pulley, and on when rotating clockwise. The rotary direction has been set to
counterclockwise as facing to the motor pulley, matching with the machine prior to shipping
