1. 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

(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 machine nameplate.
