4. Cutting metallic materials

(1) Adjust the speed Dial between scales “3” and “4”.

(2) Set the orbital position to “0” or “I”.

(3) Always use an appropriate cutting fl uid (spindle

oil, soapy water, etc.). When a liquid cutting fl uid

is not avaiable, apply grease to the back surface

of the material to be cut.

5. Pocket cutting

(1) In lumber

Aligning the blade direction with the grain of the

wood, cut step by step until a window hole is cut

in the center of the lumber. (Fig. 12)

(2) In other materials

When cutting a window hole in materials other

than lumber, initially bore a hole with a drill or

similar tool from which to start cutting.

6. Angular cutting

The base can be swiveled to both sides by up to

45° for angular cutting. (Fig. 13)

(1) Loosen the base bolt by allen wrench attached

on base and move the base fully forward.

(Fig. 8, 9)

(2) Align the scale (from 0 degrees to 45 degrees by

15-degree increments) of the semi-circular part

of the base with the [ ] mark on the gear cover.

(Fig. 14)

(3) Tighten the M5 bolt again. (Fig. 9)

(4) Set the orbital position to “0”.
NOTE: Angular cutting can not be done when

adopting chip cover or dust collector.

CONCERNING CUTTING OF STAINLESS STEEL PLATES

When used with the No. 97 blade, can cut stainless steel plates.

Note the following to adjus the unit.

CAUTION

● In order to prevent blade dislodging, damage or excessive wear on the Plunger,

please make sure to have surface of the base plate attached to the work piece while

sawing.

When cutting stainless steel plates, adjust the unit as described below:
1. Adjust the speed

Blade

Thickness of material

Dial Scale

No. 97

1/16" – 5/32" (1.5 mm – 2.5 mm)

Middle groove position

between scales “2” and “3”

NOTE: Dial scale reading is for reference only. The higher the speed is, the quicker the material

is cut. But the service life of the blade will be reduced in this case. When the speed is too

low, cutting will take longer, although the service life will be prolonged. Make adjustments

as desired.
