How To Use The Guard - Hitachi C 12FSA Technical Data And Service Manual

8-4. How to Use the Guard

(1) There is a plastic guard mounted in holder (A).
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.
Press a workpiece against the fence, and clamp it in
position with the vise. Then loosen the knob bolt M8,
press the guard against the workpiece, and secure it in
position. Next, turn the switch ON, and, after the saw
blade has reached sufficient rotation speed, pull it out to a
position where it will not contact the workpiece, slide it in as far as it will go, and press the handle down slowly
to cut a groove in both the guard and the workpiece.
[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 (guard adjustment)
Right angle cutting or bevel cutting
1
Loosen the knob bolt M8, press the guard lightly
against the workpiece, and secure it in position.
Align the cutting line on the workpiece with the saw
blade cut groove in the guard, and cut the
workpiece.
Miter cutting or compound (Miter + Bevel) cutting
2
Loosen the knob bolt M8, and move the guard back
(in the direction indicated by the arrow mark in Fig.
34) so that it does not protrude beyond the surface
of the fence. Pressing the handle downward
causes the safety cover to move upward, exposing
the saw blade so that it can be easily aligned with
the cutting line for accurate cutting of workpiece.
[CAUTION] The guard may protrude beyond the
front surface of the fence when the turn table is
turned. In such case, loosen the knob bolt M8,
move the guard so that it does not protrude
beyond the surface of the fence, and secure it in
position.
[WARNING] To avoid possible serious injury, the
customer should be cautioned never to raise the safety cover by hand while the saw blade is
rotating.
