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.

The blade plunger stroke rate can be adjusted from
the minimum to maximum nameplate stroke rate
by the pressure you apply to the trigger. Apply more
pressure to increase the speed and release pressure
to decrease speed.
2. Cutting metallic materials
CAUTION:
Press the base firmly against the workpiece.
Never apply any unreasonable force to the saw
blade when cutting. Doing so can easily break
the blade.
The motor can be locked sometimes, depending
on the combination of the material to be cut
and the blade. Whenever the motor gets locked,
switch it off immediately.
