Don’t operate in direct sun light, outdoors area and the room temperature is 40°C above or 5°C under.
Don’t operate near the heater, dew area and the humidity is 20 % less or 80% more.
Don’t operate in dusty, evaporate, combustible gas area, and stay away from corrosive material.
Avoid power cord being applied by heavy objects or excessive force, or over bend.
Power cord must keep 3 cm or above distance to the V-belt and the pulley.
In order to prevent the static interference and current leakage, all grounding works must be done properly.
Turning on the machine in the first time, use low speed to operate and check the correct rotation direction.
During machine operation, don’t touch any moving parts.
All moving parts must use the protective device to avoid the body contact and objects insertion.
Maintenance and repairs must be done by the specially trained personnel.
All spare parts for repair must be approved or supplied by the manufacturer.
Don’t use any objects or force to hit or ram the product.
Danger and caution signs:
Risks that may cause personal injury or risk to the machine are marked with

a) Synchronizer Installation:
Mounting the Synchronizer onto the flange of machine
pulley,and match the stopper with a stop groove of the
synchronizer.
With then tighten and secure 2 screws of the synchronizer.

b) Synchronizer Adjustment :
Adjust this position with the synchronizer installed onto
the sewing machine and while stopping at the UP
position.
Adjustment of UP Position
Loosen the two screws on the synchronizer joint, and set
thestop position by turning the synchronizer joint.
After adjustment, please fix it by tightening the screws.
