CAUTION:
Avoid plunge cutting for metallic materials. This
can easily damage the blade.
Never pull the switch trigger while the tip of
the saw blade is pressed against the material.
If you do so, the blade can easily be damaged
when it collides with the material.
Make absolutely sure that you cut slowly while
holding the body firmly. If you apply any
unreasonable force to the saw blade during the
Fig. 34
cutting operation, the blade can easily be
damaged.
