GENERAL SAFETY RULES
WARNING!
Read all instructions
Failure to follow all instructions listed below may result in
electric shock, fi re and/or serious injury.
The term “power tool” in all of the warnings listed below
refers to your mains operated (corded) power tool or battery
operated (cordless) power tool.
SAVE THESE INSTRUCTIONS
1) Work area
a) Keep work area clean and well lit.
Cluttered and 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
of 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.
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 safety equipment. Always wear eye
protection.
Safety equipment such as dust mask, non-skid
safety shoes, hard hat, or hearing protection used
for appropriate conditions will reduce personal
injuries.
c) Avoid accidental starting. Ensure the switch is
in the off position before plugging in.
Carrying power tools with your fi nger on the
switch or plugging in 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 these devices 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
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 toolsʼ 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 and
in the manner intended for the particular type
of power tool, taking into account the working
conditions
and the work to be performed.
Use of the power tool for operations diff erent from
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.
PRECAUTION
Keep children and infi rm persons away.
When not in use, tools should be stored out of reach
of children and infi rm
persons.

2. Power switch
Ensure that the power switch is in the OFF position. If
the plug is connected to a receptacle while the power
switch is in the ON position, the power tool will start
operating immediately, which could cause a serious
accident.
3. Extension cord
When the work area is removed from the power source,
use an extension cord of suffi cient thickness and rated
capacity. The extension cord should be kept as short as
practicable.
4. Installing tools
CAUTION
Be sure to switch power OFF and disconnect the plug
from the receptacle to avoid serious trouble.
NOTE
Concerning the tools such as bull points and cutters,
be sure to use separately sold genuine parts that are
designated by HITACHI.
(1) Wipe off and clean up the shank section of the tool, and
apply grease or machine oil onto it.
(2) Insert the shank section of the tool completely into the
hexagonal hole of the front cover at a state where the
slide grip is fully pulled in the direction of Ⓐ as shown in
Fig. 1
(3) Return the slide grip to its home position and make sure
that the tool is pulled and locked securely.
(4) Removal is carried out at a state where the slide grip is
fully pulled in the direction of Ⓐ in a manner similar to
the case of installing the tool.
CAUTION
Be sure to grip the handle and cylinder case cover
portion during work. Do not hold by the slide grip during
work: lf you pull it by mistake, the bull point could jump
out.
HOW TO USE THE DEMOLITION HAMMER (Fig. 2)
1. After placing the tip of the tool in the base hole, switch
ON.
2. By utilizing the weight of the machine and by fi rmly
holding the demolition hammer with both hands, one
can eff ectively control the subsequent recoil motion.
Proceed at a moderate work-rate, the use of too much
force will impair effi ciency.
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
Inspect the grase amount according to the timing
replacement period of the carbon brush. (See the
section MAINTENANCE AND INSPECTION.)
Ask for grease replacement at the nearest authorized
Hitachi 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. 3)
(2) Supply 30 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.
NOTE
The Hitachi Electric Hammer Grease A is of the low
viscosity type. When the grease is consumed, purchase
from an authorized Hitachi Service Center.
MAINTENANCE AND INSPECTION
CAUTION
Be sure to switch power OFF and disconnect the plug
from the receptacle to avoid serious trouble.
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. 4)
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 Numbers shown in the fi gure. 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
securely and to install the tail cover.
