injury, or may cause machine damage.
NOTE emphasizes essential information.
SAFETY
GENERAL POWER TOOL SAFETY WARNINGS
WARNING:
Read all safety warnings and all instructions.
Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.
Save all warnings and instructions for future reference.
The term “power tool” in the warnings refers to your mains-operated (corded) power tool or battery-operated
(cordless) power tool.
1) Work area safety
a) Keep work area clean and well lit.
Cluttered or dark areas invite accidents.
b) 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 or fumes.
c) Keep children and bystanders away while
operating a power tool.
Distractions can cause you to lose control.
2) Electrical safety
a) Power tool plugs must match the outlet.
Never modify the plug in any way.
Do not use any adapter plugs with earthed
(grounded) power tools.
Unmodified plugs and matching outlets will
reduce risk of electric shock.
b) Avoid body contact with earthed or grounded
surfaces such as pipes, radiators, ranges and
refrigerators.
There is an increased risk of electric shock if
your body is earthed or grounded.
c) Do not expose power tools to rain or wet
conditions.
Water entering a power tool will increase the
risk of electric shock.
d) Do not abuse the cord. Never use the cord for
carrying, pulling or unplugging the power tool.
Keep cord away from heat, oil, sharp edges
or moving parts.
Damaged or entangled cords increase the risk
of electric shock.
e) When operating a power tool outdoors, use
an extension cord suitable for outdoor use.
Use of a cord suitable for outdoor use reduces
the risk of electric shock.
f) If operating a power tool in a damp location
is unavoidable, use a residual current device
(RCD) protected supply.
Use of an RCD reduces the risk of electric shock.
3) Personal safety
a) Stay alert, watch what you are doing and use
common sense when operating a power tool.
Do not use a power tool while you are tired
or under the influence of drugs, alcohol or
medication.

English
A moment of inattention while operating power
tools may result in serious personal injury.
b) Use personal protective equipment. Always
wear eye protection.
Protective equipment such as dust mask, non-
skid safety shoes, hard hat, or hearing
protection used for appropriate conditions
will reduce personal injuries.
c) Prevent unintentional starting. Ensure the
switch is in the off-position before connecting
to power source and/or battery pack, picking
up or carrying the tool.
Carrying power tools with your finger on the
switch or energising power tools that have
the switch on invites accidents.
d) Remove any adjusting key or wrench before
turning the power tool on.
A wrench or a key left attached to a rotating part
of the power tool may result in personal injury.
e) Do not overreach. Keep proper footing and
balance at all times.
This enables better control of the power tool
in unexpected situations.
f) Dress properly. Do not wear loose clothing
or jewellery. Keep your hair, clothing and
gloves away from moving parts.
Loose clothes, jewellery or long hair can be
caught in moving parts.
g) If devices are provided for the connection of
dust extraction and collection facilities, ensure
these are connected and properly used.
Use of dust collection can reduce dust-related
hazards.
4) Power tool use and care
a) Do not force the power tool. Use the correct
power tool for your application.
The correct power tool will do the job better
and safer at the rate for which it was designed.
b) Do not use the power tool if the switch does
not turn it on and off.
Any power tool that cannot be controlled with
the switch is dangerous and must be repaired.
c) Disconnect the plug from the power source
and/or the battery pack from the power tool
before making any adjustments, changing
accessories, or storing power tools.
Such preventive safety measures reduce the
risk of starting the power tool accidentally.
d) Store idle power tools out of the reach of
children and do not allow persons unfamiliar
with the power tool or these instructions to
operate the power tool.
Power tools are dangerous in the hands of
untrained users.
e) Maintain power tools. Check for
misalignment or binding of moving parts,
breakage of parts and any other condition
that may affect the power tool’s operation.
If damaged, have the power tool repaired
before use.
Many accidents are caused by poorly
maintained power tools.
f) Keep cutting tools sharp and clean.
Properly maintained cutting tools with sharp
cutting edges are less likely to bind and are
easier to control.
g) Use the power tool, accessories and tool bits
etc. in accordance with these instructions,
taking into account the working conditions
and the work to be performed.
Use of the power tool for operations different
from those intended could result in a
hazardous situation.

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 “ ” or the 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.

not be fully transferred to the screw.
Do not attempt to use the rotary hammer in the rotation and striking function
with chuck adaptor (D) and bit attached.
5. When driving wood screws (Fig. 11)
(1) Selecting a suitable driver bit
Employ phillips screws, if possible, since the driver bit easily slips off the heads
of slotted-head screws.
(2) Driving in wood screws
Prior to driving in wood screws, make pilot holes suitable for them in the wooden
board. Apply the bit to the screw head grooves and gently drive the screws into
the holes.
After rotating the rotary hammer at low speed for a while until a wood screw in
partly driven into the wood, squeeze the trigger more strongly to obtain the
optimum driving force.
CAUTION:
Exercise care in preparing a pilot hole suitable for the wood screw taking the
hardness of the wood into consideration. Should the hole be excessively small
or shallow, requiring much power to drive the screw into it, the thread of the
wood screw may sometimes be damaged.

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 properly tightened. Should
any of the screws be loosened, retighten them immediately.
WARNING: Using this rotary hammer with loosen screws is extremely
dangerous.
3. Maintenance of the motor
The motor unit winding is the very “heart” of the power tool. Exercise due care
to ensure the winding does not become damaged and/or wet with oil or water.
4. Inspecting the carbon brushes
For your continued safety and electrical shock protection, carbon brush inspection
and replacement on this tool should ONLY be performed by a HITACHI
AUTHORIZED SERVICE CENTER.
5. How to replace grease
Low viscosity grease is applied to this rotary hammer so that it can be used for
a long period without replacing the grease. Please contact the nearest service
center for grease replacement when any grease is leaking from loosened screw.
Further use of the rotary hammer despite the grease shortage causes seizure to
reduce the service life.
CAUTION: A specific grease is used with this machine, therefore, the normal
performance of the machine may be badly affected by use of other
grease. Please be sure to let one of our service agents undertake
replacement of the grease.
6. Service and repairs
All quality power tools will eventually require servicing or replacement of parts
because of wear from normal use. To assure that only authorized replacement
parts will be used, all service and repairs must be performed by a HITACHI
AUTHORIZED SERVICE CENTER, ONLY.
