The equipment will shut itself off when overheating. The safety button does not allow the trigger to be pulled on. Without it, it is impossible to press the trigger.

The versatility of the tool during operation at various angles depends on the base plate. The tilt of the cut is set by the position of the platform.

A mandatory part, which should be in all circulars, is a spring-loaded casing. when the device is idle, it completely covers the disk. The disc is released only when there is emphasis on the workpiece. Pay attention to the location of the handle, as well as its shape.
