(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.
(4) You can cut smoothly if you set the
change lever position to straight
cutting (Fig. 16).
2. Cutting lumber
(1) When cutting lumber, make sure that
the workpiece is fastened firmly
before beginning. (Fig. 23)
Fig. 23
(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. 17). Alternatively, you can cut
cleanly if the change lever position is
set to straight cutting (Fig. 16).
CAUTION:
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
BIMETAL blade mentioned in Page 18
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.
4. Plunge cutting
With this tool, you can perform pocket
cutting on plywood panels and thin
board materials. You can carry out
pocket cutting quite easily with the saw
blade installed in reverse as illustrated
in Fig. 25, Fig. 27, and Fig. 29. Use the
saw blade that is as short and thick as
possible. We recommend for this
purpose that you use BI-METAL Blade
No. 132 mentioned in Page 18. Be sure
to use caution during the cutting
operation and observe the following
procedures.
(1) Press the lower part (or the upper
part) of the base against the
material. Pull the switch trigger
while keeping the tip of the saw
blade apart from the material. (Fig.
24, Fig. 25)
