In the work, parts to determine is fixed up, profile positioning to meet the direction of eating, avoid abnormal cut, do not false lateral pressure or curve cutting, into the smooth, avoid blade impact contact parts, resulting in saw blade damage, or the workpiece flying out, accident.

In the work, if found abnormal sound and vibration, rough cutting surface, or smell, must immediately terminate the operation, timely inspection, troubleshooting to avoid accidents.
