3. Hold power tools by insulated gripping surfaces
when performing an operation where the cutting
tool may contact hidden wiring or its own cord.
Contact with a “live” wire will make exposed metal
parts of the tool “live” and shock the operator.
4. ALWAYS wear ear protectors when using the tool
for extended periods.
Prolonged exposure to high intensity
noise can cause hearing loss.
5. Use only a depressed center wheel with a rated
capacity which is GREATER than 6,600/min. Using
any wheel a rated capacity LESS than 6,600/min
and/or an incorrect sized wheel (see
SPECIFICATIONS at page 10) may result in wheel
breakage, flying wheel fragments, and resulting
in death or serious injury.
6. NEVER touch moving parts.
NEVER place your hands, fingers or
other body parts near the tool’s moving
parts.
7. NEVER operate without all guards in place.
NEVER operate this tool without all guards or safety
features in place and in proper working order. If
maintenance or servicing requires the removal of a
guard or safety feature, be sure to replace the guard
or safety feature before resuming operation of the tool.
8. Use right tool.
Don’t force small tool or attachment to do the job
of a heavy-duty tool.
Don’t use tool for purpose not intended —for
example— don’t use circular saw for cutting tree
limbs or logs.
9. NEVER use a power tool for applications other
than those specified.

NEVER allow the tool to be operated by children,
individuals unfamiliar with its operation or
unauthorized personnel.
11. Keep all screws, bolts and covers tightly in place.
Keep all screws, bolts, and plates tightly mounted.
Check their condition periodically.
12. Do not use power tools if the plastic housing or
handle is cracked.
Cracks in the tool’s housing or handle can lead to
electric shock. Such tools should not be used until
repaired.
13. Blades and accessories must be securely mounted
to the tool.
Prevent potential injuries to yourself or others. Blades,
cutting implements and accessories which have been
mounted to the tool should be secure and tight.
14. Keep motor air vent clean.
The tool’s motor air vent must be kept clean so
that air can freely flow at all times. Check for dust
build-up frequently.
15. Operate power tools at the rated voltage.
Operate the power tool at voltages specified on its
nameplate.
If using the power tool at a higher voltage than
the rated voltage, it will result in abnormally fast
motor revolution and may damage the unit and
the motor may burn out.
16. NEVER use a tool which is defective or operating
abnormally.
If the tool appears to be operating unusually,
making strange noises, or otherwise appears
defective, stop using it immediately and arrange
for repairs by a Hitachi authorized service center.
17. NEVER leave tool running unattended. Turn power
off.
Don’t leave tool until it comes to a complete stop.
18. Carefully handle power tools.
Should a power tool be dropped or struck against
hard materials inadvertently, it may be deformed,
cracked, or damaged.
19. Do not wipe plastic parts with solvent.
Solvents such as gasoline, thinner benzine, carbon
tetrachloride, and alcohol may damage and crack
plastic parts. Do not wipe them with such solvents.
Wipe plastic parts with a soft cloth lightly
dampened with soapy water and dry thoroughly.
20. NEVER use a depressed center wheel which is cracked
or deformed or worn away (see the MAINTENANCE
AND INSPECTION section on page 13).
