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
mainsoperated (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.
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.
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.

GREASE REPLACEMENT
This Demolition Hammer is of full air-tight construction to
protect against dust and to prevent lubricant leakage.
Therefore, this Demolition Hammer can be used without
lubrication for long periods. Replace the grease as described
below.
Grease Replacement Period
After purchase, replace grease after every 6 months of
usage. Ask for grease replacement at the nearest authorized
Service Center.
MAINTENANCE AND INSPECTION
CAUTION
Be sure to switch OFF and disconnect the attachment
plug from the receptacle to avoid a serious accident.
1. Inspecting accessories
Since use of a dull accessory, such as a bull point, a
cutter, etc. will degrade effi ciency and cause possible
motor malfunction, sharpen or replace with a new one 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. Inspecting the retainer
The retainer may become loose due to excessive use.
Always, pay attention to its proper functioning to securely
hold the accessory shank portion. If any wear and tear is
found, bring this Demolition Hammer to an authorized
service center for maintenance service.
4. 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.
5. Inspecting the carbon brushes (Fig. 6)
The Motor employs carbon brushes which are
consumable parts. When they become worn to or near
the “wear limit” ⓐ, it results 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 Fig. 6. In addition,
always keep carbon brushes clean and ensure that they
slide freely within the brush holders.
CAUTION
In the operation and maintenance of power tools, the
safety regulations and standards prescribed in each
country must be observed.
