Dos and Don'ts

1. Always be aware of the needle's up-and-down movement, and do not turn your attention from
the machine while it is running.
2. When changing the needle, the presser foot or any other parts, always disconnect the machine
by turning the power switch to OFF.
3. Do not place anything on the foot control, or the machine will start inadvertently and the foot
control or motor can burn out.
4. When using your serger for the first time, place a fabric scrap under the presser foot and run the
machine without thread for a few minutes. Wipe away any oil that appears.
5. Do not pull fabric from the rear of the machine. Such action can damage the machine.
6. To prevent possible injury, always avoid body contact with any moving parts and the machine
mechanism.
7. NEVER sew over pins.
Special Caution: Unplug the power cord from the electrical outlet when the machine is not in use.
