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, fi re 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 fl ammable 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.
Unmodifi ed 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 infl uence of drugs,
alcohol or medication.
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 fi nger 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.
English
15
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 aff ect the power toolʼs
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 diff erent from those intended could result in a
hazardous situation.
5) Service
a) Have your power tool serviced by a qualifi ed repair person using only identical
replacement parts.
This will ensure that the safety of the power tool is maintained.
CAUTION
Keep children and infi rm persons away.
When not in use, tools should be stored out of reach of children and infi rm persons.
DEMOLITION HAMMER SAFETY WARNINGS
1. Wear ear protectors
Exposure to noise can cause hearing loss.
2. Use auxiliary handles supplied with the tool.
Loss of control can cause personal injury.
3. Hold power tool by insulated gripping surfaces, when performing an operation
where the cutting accessory may contact hidden wiring or its own cord. Cutting
accessory contacting a "live" wire may make exposed metal parts of the power tool
"live" and could give the operator an electric shock.
4. Do not touch the bit during or immediately after operation. The bit becomes very
hot during operation and could cause serious burns.
5. Before starting to break, chip or drill into a wall, fl oor or ceiling, thoroughly confi rm
that such items as electric cables or conduits are not buried inside.

GREASE REPLACEMENT
This machine is of full air-tight construction to protect against dust and to prevent lubricant
leakage. This machine can be used without grease supplement for an extended period of time.
However, perform the grease replacement to maintain the service life. Replace the grease as
described below.
1. Grease Replacement Period
You should look at the grease when you change the carbon brush (See item 4 in the
section MAINTENANCE AND INSPECTION).
Ask for grease replacement at the nearest Hitachi Authorized Service Center.
In the case that you are forced to change the grease by yourself, please follow the following
points.
2. How to replace grease
CAUTION
Before replacing the grease, turn the power off and pull out the plug from the
receptacle.
(1) Remove the crank cover and wipe off the
old grease inside. (Fig. 6)
(2) Supply 76 g (the standard volume to cover
the connecting rod) of Hitachi Electric
Hammer Grease A to the crank case.
(3) After replacing the grease, install the
crank cover securely. At this time, do not
damage or lose the oil seal.
NOTE
The Hitachi Electric Hammer Grease A is of the low viscosity type. When the grease is

1. Inspecting the tool
Since use of a dull tool will degrade effi ciency and cause possible motor malfunction,
sharpen or replace the tool as soon as abrasion is noted.
2. Inspecting the mounting screws
Regularly inspect all mounting screws and ensure that they are properly tightened. Should
any of the screws be loose, retighten them immediately. Failure to do so could result in
serious hazard.
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 (Fig. 7)
The Motor employs carbon brushes which are
consumable parts. When they become worn to
or near the “wear limit”, it could result in motor
trouble. When an auto-stop carbon brush is
equipped, the motor will stop automatically. At
that time, replace both carbon brushes with new
ones which have the same carbon brush Number
shown in the figure. In addition, always keep
carbon brushes clean and ensure that they slide
freely within the brush holders.
5. Replacing carbon brushes
Loosen the set screw and remove the tail cover.
Remove the brush caps and carbon brushes. After replacing the carbon brushes, do not
forget to tighten the brush caps properly and install the tail cover.
6. Replacing supply cord
If the replacement of the supply cord is necessary, this has to be done by Hitachi
Authorized Service Center in order to avoid a safety hazard.
If the supply cord of this power tool is damaged, it must be replaced by a specially prepared
cord available through the service organization.
7. Service parts list
CAUTION
Repair, modifi cation and inspection of Hitachi Power Tools must be carried out by
a Hitachi Authorized Service Center.
This Parts List will be helpful if presented with the tool to the Hitachi Authorized
Service Center when requesting repair or other maintenance.
In the operation and maintenance of power tools, the safety regulations and
standards prescribed in each country must be observed.
