Safety instructions
GENERAL POWER TOOL SAFETY WARNING
WARNING Read all safety warnings and all
instructions. Failure to follow the warnings and
instructions may result in electric shock, 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 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.
Unmodied plugs and matching outlets will reduce risk
of electric shock.

7
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 in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 nger on the
switch or energising power tools that have the switch
on invites accidents.

8
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.

9
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.
5) SERVICE
a) Have your power tool serviced by a qualied repair
person using only identical replacement parts.
This will ensure that the safety of the power tool is
maintained.
ADDITIONAL SAFETY WARNINGS FOR BREAKER
HAMMER SAFETY WARNINGS
a) Wear ear protectors. Exposure to noise can cause
hearing loss.
b) Use auxiliary handle(s), if supplied with the tool.
Loss of control can cause personal injury.
c) Hold power tool by insulated gripping surfaces
only, 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.
d) ALWAYS ensure that the auxiliary handle is rmly
afxed and secure.

10
e) ALWAYS use this product when standing on a rm
and secure platform or the ground. (DO NOT USE ON
LADDERS OR STEPS)
f) The power tool shall not be wet or applied in wet
environment.
g) The voltage of the power source must agree with the
voltage specied on the rating label of the machine.
h) Check the product, its power cord and plug as well as
accessories for damage before each use. Do not use
the product if it is damaged or shows wear.
i) Double check that the accessories and attachments
are properly xed. A short-time test running in no-load
condition will be helpful to identify any problems.
j) Use suitable detectors to determine if utility lines are
hidden in the work area or call the local utility company
for assistance. Contact with electric lines can lead to
re and electric shock. Damaging a gas line can lead
to explosion. Penetrating a water line causes property
damage or may cause an electric shock.
k) Keep the handles dry to ensure safe control. Grip the
product securely with two hands so you have full control
at all times.
l) The chisel, chuck and the work piece can become very
hot while working. Do not touch them before they have
cooled down.
m)Ensure that the air vents are always unobstructed
and clear. Clean them if necessary with a soft brush.
Blocked air vents may lead to overheating and damage
the product.
n) Switch off the power tool immediately when the bit
jams. The chisel jams when: the power tool is subject
to overload or it becomes wedged in the workpiece.
Switch the power tool off and then loosen the bit.
o) Switch the product off immediately if you are disturbed
while working by other people entering the working
area. Always let the product come to complete stop
before putting it down.

11
p) Do not overwork yourself. Take regular breaks to
ensure you can concentrate on the work and have full
control over the product.
q) Always keep the power cord behind the power tool.
The following information applies to professional users only
but is good practice for all users:
ADDITIONAL SAFETY WARNINGS FOR
CONSTRUCTION DUST
The updated Control of Substances Hazardous to Health
Regulations 1st October 2012 now also targets to reduce the
risks associated with silica, wood and gypsum dusts.
Construction workers are one of the at-risk groups within this
because of the dust that they breathe: silica dust is not just a
nuisance; it is a real risk to your lungs!
Silica is a natural mineral present in large amounts in things
like sand, sandstone and granite. It is also commonly found in
many construction materials such as concrete and mortar. The
silica is broken into very ne dust (also known as Respirable
Crystalline Silica or RCS) during many common tasks such as
cutting, drilling and grinding. Breathing in very ne particles of
crystalline silica can lead to the development of:
• lung cancer
• Silicosis
• Chronic obstructive pulmonary disease (COPD).
And breathing in ne particles of wood dust can lead to the
development of Asthma. The risk of lung disease is linked to
people who regularly breathe construction dust over a period of
time, not on the odd occasion.
To protect the lung, the COSHH Regulations sets a limit on the
amount of these dusts that you can breathe (called a Workplace
Exposure Limit or WEL) when averaged over a normal working
day. These limits are not a large amount of dust: when compared
to a penny it is tiny – like a small pinch of salt:

12
This limit is the legal maximum; the most you can breathe
after the right controls have been used.
How to reduce the amount of dust?
1. Reduce the amount of cutting by using the best sizes of
building products.
2. Use a less powerful tool e.g. a block cutter instead of
angle grinder.
3. Using a different method of work altogether – e.g. using
a nail gun to direct fasten cable trays instead of drilling
holes rst.
Please always work with approved safety equipment, such as
those dust masks that specially designed to lter out microscopic
particles and use the dust extraction facility at all time.
For more information please see the HSE website:
http://www.hse.gov.uk/construction or http://www.hse.gov.uk/
pubns/cis69.pdf
WARNING! Some dust particles created by
power sanding, sawing, grinding, drill and other
construction jobs contain chemicals known to
cause cancer, birth defects or other reproductive
harm. Some examples of these chemicals are:
• Lead from lead-based paints.
• Crystalline silica from bricks and cement and
other masonry products.
• Arsenic and chromium from chemically treated
timber.
Your risk from these exposures varies, depending
upon how often you do this type of work. To reduce
your exposure to these dusts:
• Work in a well-ventilated.
• Work with approved protective equipment, such
as those dust masks that are specially designed
to lter microscopic particles.

VIBRATION
The European Physical Agents (Vibration) Directive has
been brought in to help reduce hand arm vibration syndrome
injuries to power tool users. The directive requires power tool
manufacturers and suppliers to provide indicative vibration
test results to enable users to make informed decisions as to
the period of time a power tool can be used safely on a daily
basis and the choice of tool.
SEE TECHNICAL SPECIFICATIONS IN THE INSTRUCTION
MANUAL FOR THE VIBRATION LEVELS OF YOUR TOOL.
The declared vibration emission value should be used as a
minimum level and should be used with the current guidance
on vibration.
Calculating the actual period of use can be difcult and the
HSE website has further information.
The declared vibration total value has been measured in
accordance with EN 60745-1 and EN 60745-2-6 and may be
used for compare one tool with another.
The declared vibration total value may also be used in a
preliminary assessment of exposure.
WARNING! The vibration emission during actual use
of the power tool can differ from the declared total
value depending on the ways in which the tool is used:
• How the materials are grinded, cut or drilled.
• If the tool is in good condition and well maintained.
• Use correct accessory for the tool and ensure it is
sharp and in good condition.
• The tightness of the grip on the handles.
• And the tool is being used as intended by its
design and these instructions.
While working with this power tool, hand/arm
vibrations occur. Adopt the correct working
practices in order to reduce the exposure to
vibration. This tool may cause hand-arm vibration
syndrome if its use is not adequately managed.

14
WARNING! Identify safety measures to protect the
operator that are based on an estimation of exposure
in the actual conditions of use (taking account of all
parts of the operating cycle such as the times when
the tool is switched off and when it is running idle in
addition to the trigger time).
Note:
• The use of other tools will reduce the users’ total
working period on this tool.
• Helping to minimise your vibration exposure risk.
ALWAYS use sharp chisels, drills and blades.
• Maintain this tool in accordance with these
instructions and keep well lubricated (where
appropriate).
• Avoid using tools in temperatures of 10 °C or
less. Plan your work schedule to spread any high
vibration tool use across a number of days.
HEALTH SURVEILLANCE
All employees should be part of an employer’s health
surveillance scheme to help identity any vibration related
diseases at an early stage, prevent disease progression and
help employees stay in work.
VIBRATION AND NOISE REDUCTION
To reduce the impact of noise and vibration emission, limit
the time of operation, use low-vibration and low-noise
