⅜ 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. 16 and Fig. 18).
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. 17, Fig. 19)

⅜ To maximize cutting efficiency for the materials

you are using and working conditions, adjust
the speed of the saw blade and the switching to
swing cutting.

1. Cutting metallic materials

CAUTION:

⅜ Press the base firmly against the workpiece.

⅜ Never apply any unreasonable force to the

saw blade when cutting. Doing so can easily
break the blade.

(1) Fasten a workpiece firmly before operation.

(Fig. 20)

(2) When cutting metallic materials, use proper

machine oil (turbine oil, etc.). When not
using liquid machine oil, apply grease over
the workpiece.

CAUTION: The service life of the saw blade

will be drastically shortened if
you don’t use machine oil.

(3) Use the dial to adjust the speed of the saw

blade to suit your working conditions and
materials.

(4) You can cut smoothly if you set the change

lever position to straight cutting (Fig. 14).
