CAUTION: Always lock the switch when
carrying or storing the tool eliminate
unintentional starting.
(2) Trigger switch
This tool is equipped with a variable speed
controlled trigger switch. The tool can be turned
"ON" or "OFF" by squeezing or releasing the trigger.
The blade plunger stroke rate can be adjusted from
the minimum to maximum nameplate stroke rate
by the pressure you apply to the trigger. Apply more
pressure to increase the speed and release pressure
to decrease speed.
2. Cutting metallic materials
CAUTION:
Press the base firmly against the workpiece.
Never apply any unreasonable force to the saw
blade when cutting. Doing so can easily break
the blade.
The motor can be locked sometimes, depending
on the combination of the material to be cut
and the blade. Whenever the motor gets locked,
switch it off immediately.
(1) Fasten a workpiece firmly before operation.
(Fig. 20)
(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. 21)
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 26 for the saw blade
since it is tough and hardly breaks.
