䡬 Select a saw blade of the most appropriate length.
Ideally, the length protruding from the base of the
saw blade after subtracting the stroke quantity should
be larger than the material (see Fig. 17 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. 19,
Fig. 20)

䡬 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
䡬 Press the base firmly against the workpiece.
䡬 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. 21)
Fig. 21
(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. 15).
2. Cutting lumber
(1) When cutting lumber, make sure that the workpiece
is fastened firmly before beginning. (Fig. 22)
Fig. 22
(2) You can cut efficiently if the speed of the saw blade is
set to dial scale “5”.
(3) You can cut efficiently if the change lever position is
set to swing cutting (Fig. 16). Alternatively, you can
cut cleanly if the change lever position is set to straight
cutting (Fig. 15).
CAUTION
䡬 Never apply any unreasonable force to the saw blade
when cutting. Also remember to press the base
against the lumber firmly.
3. Sawing curved lines
We recommend that you use the BI-METAL blade
mentioned in Table 2 for the saw blade since it is tough
and hardly breaks.
CAUTION
Delay the feed speed when cutting the material into
small circular arcs. An unreasonably fast feed may
break the blade.
