ORIGINAL INSTRUCTIONS
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. 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
8
EN
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) Battery tool use and care
a) Recharge only with the charger specified
by the manufacturer. A charger that is suitable
for one type of battery pack may create a risk of
fire when used with another battery pack.
b) Use power tools only with specifically
designated battery packs. Use of any other
battery packs may create a risk of injury and fire.
c) When battery pack is not in use, keep it
away from other metal objects, like paper
clips, coins, keys, nails, screws or other
small metal objects, that can make a
connection from one terminal to another.
Shorting the battery terminals together may cause
burns or a fire.
d) Under abusive conditions, liquid may be
ejected from the battery; avoid contact.
If contact accidentally occurs, flush with
water. If liquid contacts eyes, additionally
seek medical help. Liquid ejected from the
battery may cause irritation or burns.
6) Service
a) Have your power tool serviced by a
qualified repair person using only identical
replacement parts. This will ensure that the
safety of the power tool is maintained.
HAMMER SAFETY
WARNINGS
1. Wear ear protectors. Exposure to noise can
cause hearing loss.
2. Use auxiliary handles, If supplied with the
tool. Loss of control can cause personal injury.
3. Hold power tools by insulated gripping
surfaces, when performing an operation
where the cutting accessory may contact
hidden wiring. Cutting accessory contacting a
‘live’ wire may make exposed metal parts of the
power tool ‘live’ and could give the operator an
electric shock.
SAFETY WARNINGS FOR
BATTERY PACK
a) Do not dismantle, open or shred cells or
battery pack.
b) Do not short-circuit a battery pack. Do
not store battery packs haphazardly in
a box or drawer where they may short-
circuit each other or be short-circuited by
conductive materials. When battery pack is
not in use, keep it away from other metal objects,
like paper clips, coins, keys, nails, screws or other
small metal objects, that can make a connection
from one terminal to another. Shorting the battery
terminals together may cause burns or a fire.
c) Do not expose battery pack to heat or fire.
Avoid storage in direct sunlight.
d) Do not subject battery pack to mechanical
shock.
e) In the event of battery leaking, do not
allow the liquid to come into contact

The declared vibration total value may be used for
comparing one tool with another, and may also be used
in a preliminary assessment of exposure.
WARNING: The vibration emission value during
actual use of the power tool can differ from the
declared value depending on the ways in which the tool
is used dependant on the following examples and other
variations on how the tool is used:
How the tool is used and the materials being cut or
drilled.
The tool being in good condition and well maintained
Using the correct accessory for the tool and ensuring it
is sharp and in good condition.
The tightness of the grip on the handles and if any anti
vibration accessories are used.
And the tool is being used as intended by its design
and these instructions.
This tool may cause hand-arm vibration
syndrome if its use is not adequately managed
WARNING: To be accurate, an estimation of
exposure level in the actual conditions of use
should also take account of all parts of the operating
cycle such as the times when the tool is switched off
and when it is running idle but not actually doing the
job. This may signicantly reduce the exposure level
over the total working period.
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)
If the tool is to be used regularly then invest in anti
vibration accessories.
