SAFETY
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 tires 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.
(3) Avoid accidental starting. Be sure switch is off before plugging in. Carrying tools
with your finger on the switch or plugging in tools that have the switch on invites
4
accidents.
eliminates the need for the three wire grounded power cord and
(4) Remove adjusting keys or wrenches before turning the tool on. A wrench or a key
that is left attached to a rotating part of the tool may result in personal injury.
(5) Do not overreach. Keep proper footing and balance at all times. Proper footing and
balance enables better control of the tool in unexpected situations.

shoes, hard hat, or hearing protection must be used for appropriate conditions.
4. Tool Use and Care (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 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.
5. Service (1) Tool service must be performed only by qualified repair personnel. Service or
maintenance performed by unqualified personnel could result in a risk of injury.
(2) When servicing a tool, use only identical replacement parts. Follow instructions in
the Maintenance section of this manual. Use of unauthorized parts or failure to
follow Maintenance Instruction may create a risk of electric shock or injury.

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: Only Hitachi Authorized Service Center should disassemble or assemble this power
tool, and only genuine HITACHI replacement parts should be installed.
Clean the exterior of the power tool only with a soft cloth moistened with soapy water,
and dry thoroughly. Never use solvents, gasoline or thinners on plastic components; otherwise the plastic may dissolve.

Pulling the trigger and pushing the stopper, it keeps the switched-on condition which is
convenient for continuous running. When switching off, the stopper can be disconnected by pulling the trigger again.
NOTE:
If the L-side of push button is pressed for reverse bit rotation, the stopper cannot be used.
2. Drilling
When drilling, start the drill slowly, and gradually increasing speed as you drill.Always apply pressure in a straight line with the bit. Use enough pressure to keep
drilling, but do not push hard enough to stall the motor or deflect the bit.
To minimize stalling or breaking through the material, reduce pressure on drill and
ease the bit through the last part of the hole.
If the drill stalls, release the trigger immediately, remove the bit from the work and
start again. Do not click the trigger on and off in an attempt to start a stalled drill. This can damage the drill.
WARNING: The larger the drill bit diameter, the larger the reactive force on your arm.
Be careful not to lose control of the drill because of this reactive force. To maintain firm control, establish a good foothold, use side handle, hold the drill tightly with both hand, and ensure that the drill is vertical to the material being drilled.
MAINTENANCE AND INSPECTION
WARNING: Be sure to switch power OFF and disconnect the plug from the
receptacle during maintenance and inspection.
1. Inspecting the drill bits
Since use of a dull tool will cause motor malfunctioning and degraded efficiency, replace the drill bit with a new one or resharpening without delay when abrasion is noted.
2. Inspecting the screws
Regularly inspect all screws and ensure that they are fully tightened. Should any of the screws be loosened, retighten them immediately.
WARNING: Using this hammer drill with loosened screws is extremely dangerous.
3. Keeping after use
