(1) Fasten a workpiece firmly before operation.
(Fig. 27)
(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 firmly before beginning. (Fig. 28)
CAUTION: Never apply any unreasonable force
to the saw blade when cutting. Also
remember to press the base against
the lumber firmly.
4. Sawing curved lines
We recommend that you use the BIMETAL
blade mentioned in Page 31 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 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. 30, Fig. 32, and
Fig. 34. 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 31.
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. 29, Fig. 30)
(2) Raise the handle slowly and cut in with the saw
blade little by little. (Fig. 31, Fig. 32)
(3) Hold the body firmly until the saw blade
completely cuts into the material. (Fig. 33, Fig. 34)
