1. After starting the machine, place the saw blade on the workpiece. Otherwise, when the saw blade is stuck in the workpiece, there is a risk of rebound.

2. Keep the handle dry, clean and free of grease. A greasy handle is very slippery and may lead to inability to control the machine.

3. Be sure to fix the workpiece to be processed. Do not process workpieces that are too small to be fixed, because the distance between the hand and the rotating saw blade will be too close.

4. Do not use a saw blade that is blunt, cracked, bent or damaged. If the saw blade is blunt or the saw teeth are deformed, the friction during sawing will increase due to the too small saw kerf. The saw blade is easily clamped and causes rebound.
