8-3. How to Use Guard

(1) Groove cutting in guard

There is a plastic guard mounted in holder (A) (Fig. 28).
To allow accurate grooving of the guard with the saw blade that is
actually going to be used on the machine, the groove is not
precut at the factory. Please follow the procedures below to make
a groove in the guard. In order to cut a groove in the guard at a
constant speed, press a workpiece of 35 mm (1-3/8") square
against the fence and clamp it in position with the vise ass'y.
Loosen the 6 mm knob bolt and press the guard against the
workpiece then secure it in position. Slide the motor head up to
the full retract position. Turn on the switch, and after the saw
blade has reached sufficient rotation speed, press the handle
down slowly and slide it as far as it will go to cut a groove in both
the guard and the workpiece.
* For USA/CAN, the Models C 12LSH and C 12RSH are equipped with a fixed guard.
CAUTION: As the guard may be damaged or broken if the groove is cut too quickly, the customer
should be advised to perform this operation slowly and smoothly.

(2) Positioning of cutting lines (Adjustment of guard)

Instruct the customers as follows:
Right angle cutting or bevel cutting
1
Loosen the 6 mm knob bolt, press the guard lightly against
the workpiece, and secure it in position.
Align the ink line on the workpiece with the groove of the
guard, and cut the workpiece.
Miter cutting or compound (Miter + Bevel) cutting
2
Loosen the 6 mm knob bolt and move the guard back in the
arrow direction in Fig. 30 so that it does not protrude beyond
the fence surface. Pressing the handle downward causes
the protective cover to move upward, exposing the saw
blade so that it can be easily aligned with the ink line for
accurate cutting of workpiece.
CAUTION: The guard may protrude beyond the fence surface
when the turn table is turned. In such case, loosen
the 6 mm knob bolt, move the guard so that it does
not protrude beyond the fence surface, and secure it
in position.
WARNING: To avoid possible serious injury, the customer should be cautioned never to raise the
protective cover by hand while the saw blade is rotating.
