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.
