GENERAL SAFETY RULES
WARNING: Read and understand all instructions.
Failure to follow all instructions listed below, may result in electric shock,
fire and/or serious personal injury.
SAVE THESE INSTRUCTIONS
1. Work Area
(1) Keep your work area clean and well lit. Cluttered benches and dark areas invite
accidents.
(2) Do not operate power tools in explosive atmospheres, such as in the presence of
flammable liquids, gases, or dust. Power tools create sparks which may ignite the
dust of fumes.
(3) Keep bystanders children, and visitors away while operating a power tool.
Distractions can cause you to lose control.
2. Electrical Safety
(1) Double Insulated tools are equipped with a polarized plug (one blade is wider than
the other). This plug will fit in a polarized outlet only one way. If the plug does not
fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified
electrician to install a polarized outlet. Do not change the plug in any way. Double
Insulation
grounded power supply system.
(2) Avoid body contact with grounded surfaces such as pipes, radiators, ranges and
refrigerators. There is an increased risk of electric shock if your body is grounded.
(3) Do not expose power tools to rain or wet conditions. Water entering a power tool
will increase the risk of electric shock.
(4) Do not abuse the cord. Never use the cord to carry the tools or pull the plug from
a receptacle. Keep cord away from heat, oil, sharp edges or moving parts. Replace
damaged cords immediately. Damaged cords increase the risk of electric shock.
(5) When operating a power tool outside, use an outdoor extension cord marked “W-
A” or “W”. These cords are rated for outdoor use and reduce the risk of electric
shock.
3. Personal Safety
(1) Stay alert, watch what you are doing and use common sense when operating a
power tool. Do not use tool while tired or under the influence of drugs, alcohol, or
medication. A moment of inattention while operating power tools may result in
serious personal injury.
(2) Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep
your hair, clothing and gloves away from moving parts. Loose clothes, jewelry, or
long hair can be caught in moving parts.

(1) Use clamps or other practical way to secure and support the workpiece to a stable
platform. Holding the work by hand or against your body is unstable and may lead
to loss of control.
(2) Do not force tool. Use the correct tool for your application. The correct tool will do
the job better and safer at the rate for which it is designed.
(3) Do not use tool if switch does not turn it on or off. Any tool that cannot be controlled
with the switch is dangerous and must be repaired.
(4) Disconnect the plug form the power source before making any adjustments,
changing accessories, or storing the tool. Such preventive safety measures reduce
the risk of starting the tool accidentally.
(5) Store idle tools out of reach of children and other untrained persons. Tools are
dangerous in the hands of untrained users.
(6) Maintain tools with care. Keep cutting tools sharp and clean. Properly maintained
tools, with sharp cutting edges are less likely to bind and are easier to control.
(7) Check for misalignment or binding of moving parts, breakage of parts, and any
other condition that may affect the tool's operation. If damaged, have the tool
serviced by a HITACHI authorized service center before using. Many accidents are
caused by poorly maintained tools.
(8) Use only accessories that are recommended by the manufacturer for your model.
Accessories that may be suitable for one tool, may become hazardous when used
with another tool.

DOUBLE INSULATION FOR SAFER OPERATION
To ensure safer operation of this power tool, HITACHI has adopted a double insulation
design. “Double insulation” means that two physically separated insulation systems have
been used to insulate the electrically conductive materials connected to the power supply
from the outer frame handled by the operator. Therefore, either the symbol “
words “Double insulation” appear on the power tool or on the nameplate.
Although this system has no external grounding, you must still follow the normal electrical
safety precautions given in this Instruction Manual, including not using the power tool in
wet environments.
To keep the double insulation system effective, follow these precautions:
䡬 Only HITACHI AUTHORIZED SERVICE CENTER should disassemble or assemble this
power tool, and only genuine HITACHI replacement parts should be installed.
䡬 Clean the exterior of the power tool only with a soft cloth moistened with soapy water,
