(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. Cutting lumber
When cutting lumber, make sure that the workpiece
is fastened fi rmly before beginning. (Fig. 18)
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 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.
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 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. 19, Fig. 20)
(2) Raise the handle slowly and cut in with the saw blade
little by little. (Fig. 21, Fig. 22)
(3) Hold the body fi rmly until the saw blade completely
cuts into the material. (Fig. 23, Fig. 24)

CAUTION
Avoid plunge cutting for metallic materials. This
can easily damage the blade.
Never pull the switch trigger while the tip of the
saw blade is pressed against the material. If you
do so, the blade can easily be damaged when it
collides with the material.
Make absolutely sure that you cut slowly
while holding the body fi rmly. If you apply any
unreasonable force to the saw blade during
the cutting operation, the blade can easily be
damaged.
