English
(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. 10).
3. Cutting lumber
(1) When cutting lumber, make sure that the workpiece is
fastened fi rmly before beginning. (Fig. 18)
(2) You can cut effi ciently if the speed of the saw blade is
set to dial scale "6".
(3) You can cut effi ciently if the change lever position
is set to orbital cutting (Fig. 11). Alternatively, you
can cut cleanly if the change lever position is set to
straight cutting (Fig. 10).
CAUTION
Never apply any unreasonable force to the saw
blade when cutting. Also remember to press the
base against the lumber fi rmly.
4. Sawing curved lines
We recommend that you use the BIMETAL blade
mentioned in Page 16 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.
5. Plunge cutting
With this tool, you can perform plunge cutting on
plywood panels and thin board materials. You can
carry out plunge cutting quite easily with the saw
blade installed in reverse as illustrated in Fig. 20, Fig.
22, and Fig. 24. 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 16. 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. 19, Fig. 20)
(2) Raise the handle slowly and cut in with the saw blade
little by little. (Fig. 21, Fig. 22)
