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.
