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. 18 and Fig. 19).

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. 20, Fig. 21)

1. Cutting metallic materials
Fig. 21
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.
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.
(1) Fasten a workpiece firmly before
operation. (Fig.22)
Fig. 22
(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.
