Before Cutting - Hitachi C 12LSH Handling Instructions Manual

English
AFTER CONNECTING THE POWER PLUG TO AN APPROPRIATE AC POWER SOURCE,
CHECK THE OPERATION OF THE TOOL AS FOLLOWS:
10. Trial Run
After confi rming that no one is standing behind, the power tool start and confi rm that no
operating abnormalities exist before attempting a cutting operation.
11. Inspect the rotating stability of the saw blade.
For precise cutting, rotate the saw blade and check for defl ection to confi rm that the blade
is not noticeably unstable; otherwise vibrations might occur and cause an accident.

BEFORE CUTTING

1. Cutting a groove on the guard
Holder (A) has a guard (see Fig. 7) into
which a groove must be cut.
Loosen the 6 mm knob bolt to retract the
guard slightly. After placing a suitable
wooden piece to sit on the fence and
the table surfaces, fi x it with the vise
assembly.
After the switch has been turned on and
the saw blade has reached maximum
speed, slowly lower the handle to cut a
groove on the guard.
CAUTION
Do not cut the groove too quickly; otherwise the guard might become damaged.
2. Positioning the table insert
Table inserts are installed on the turntable. When shipping the tool from the factory, the
table inserts are so fi xed that the saw blade does not contact them. The burr of the bottom
surface of the workpiece is remarkably reduced, if the table insert is fi xed so that the gap
between the side surface of the table insert and the saw blade will be minimum. Before
using the tool, eliminate this gap in accordance with the following procedure.
(1) Right angle cutting (Fig. 8-a)
Loosen the three 5 mm machine screws,
then secure the left side table insert and
temporarily tighten the 5 mm machine
screws of both ends. Then fi x a workpiece
(about 200 mm wide) with the vise assembly
and cut it off . After aligning the cutting
surface with the edge of the table insert,
securely tighten the 5 mm machine screws
of both ends. Remove the workpiece and
securely tighten the 5 mm center machine
screw. Adjust the right hand table insert in the same way.
