Hitachi CR 18DMR instruction manual Switch operation, Cutting metallic materials

English

Vibration can damage the saw blade if the base is not pressed firmly against the workpiece. Furthermore, a tip of the saw blade can sometimes contact the inner wall of the pipe, damaging the saw blade.

Select a saw blade of the most appropriate length. Ideally, the length protruding from the base of the saw blade after subtracting the stroke should be larger than the material (see Fig. 21 and Fig. 23).

If you cut a large pipe, large block of wood, etc., that exceeds the cutting capacity of a blade; there is a risk that the blade may contact with the inner wall of the pipe, wood, etc., resulting in damage. (Fig. 22, Fig. 24)
