Before Cutting - Hitachi C 10FSH Safety Instructions And Instruction Manual

If the brake fails to engage frequently, depress and release the trigger switch to turn the tool on and off 4 or 5
times. If the brake still does not engage, have the tool serviced at a Hitachi authorized service center.
Always confi rm that the saw blade has completely stopped before raising it from the workpiece.
The brake is not a substitute for a properly functioning lower guard. Check the function of the lower guard
before each use. Serious personal injury may occur if the lower guard does not move smoothly and cover the
blade properly.
WARNING:
Please be aware of the reaction of the Motor Head (Fig.1) when the brake is activated.
Braking causes the Motor Head to jerk downward and the user should be prepared
for this reaction, especially when the trigger switch is released before the blade
is completely down. Failure to be familiar with, and prepared for, the operational
characteristics of the tool may cause serious injury.
AFTER CONNECTING THE POWER PLUG TO AN APPROPRIATE AC POWER SOURCE,
CHECK THE OPERATION OF THE TOOL AS FOLLOWS:
12. 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.
13. 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. Positioning the table insert

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
Loosen the three 6mm machine screws, then secure the left side table insert and temporarily tighten
the 6mm machine screws of both ends. Then fi x a workpiece (about 7-7/8" (200mm) wide) with the vise
assembly and cut it off . After aligning the cutting surface with the edge of the table insert, securely tighten
the 6mm machine screws of both ends. Remove the workpiece and securely tighten the 6mm center
machine screw. Adjust the right hand table insert in the same way.
(2) Left and right bevel angle cutting
Adjust the table insert in the manner shown in Fig. 8-b and Fig. 8-c following the same procedure for right
angle cutting.
CAUTION:
After adjusting the table insert for right angle cutting, the table insert will be cut to
some extent if it is used for bevel angle cutting.
When bevel cutting operation is required, adjust the table insert for bevel angle
cutting.
2. Checking the saw blade lower limit position
Check that the saw blade can be lowered 13/32" to 7/16" (10mm to 11mm) below the table insert as shown in
Fig. 9.
When you replace a saw blade with a new one, adjust the lower limit position so that the saw blade will not cut
the turntable or complete cutting cannot be done.
To adjust the lower limit position of the saw blade, follow the procedures (1) to (4) indicated below. (Fig. 10)
