(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:

䡬 Press the base firmly against the workpiece.

䡬 Never apply any unreasonable force to the saw

blade when cutting. Doing so can easily break

the blade.

䡬 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. 23)

(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. 24)

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.
