PRODUCT SAFETY
GENERAL POWER TOOL
SAFETY WARNINGS
WARNING: Read all safety warnings,
instructions, illustrations and specifications
provided with this power tool. Failure to follow all
instructions listed below 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 and clothing 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.
h) Do not let familiarity gained from frequent use
of tools allow you to become complacent and
ignore tool safety principles. A careless action
can cause severe injury within a fraction of a
second.
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 remove the battery pack, if detachable, 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 and accessories. 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.

7
Cordless Impact Driver WX291 WX291.X
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.
h) Keep handles and grasping surfaces dry, clean
and free from oil and grease. Slippery handles
and grasping surfaces do not allow for safe
handling and control of the tool in unexpected
situations.
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.
e) Do not use a battery pack or tool that is damaged
or modified. Damaged or modified batteries may
exhibit unpredictable behaviour resulting in fire,
explosion or risk of injury.
f) Do not expose a battery pack or tool to fire or
excessive temperature. Exposure to fire or
temperature above 130 °C may cause explosion.
g) Follow all charging instructions and do not
charge the battery pack or tool outside the
temperature range specified in the instructions.
Charging improperly or at temperatures outside
the specified range may damage the battery and
increase the risk of fire.
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.
b) Never service damaged battery packs. Service of
battery packs should only be performed by the
manufacturer or authorized service providers.

emission value have been measured in accordance with a
standard test method and may be used for comparing one
tool with another.
The declared vibration total value and the declared
noise emission value may also be used in a preliminary
assessment of exposure.
WARNING: The vibration and noise emissions
during actual use of the power tool can differ
from the declared value depending on the ways in which
the tool is used especially what kind of workpiece is
processed 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.
The use of 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 and noise 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 significantly reduce the exposure level over the total
working period.
Helping to minimise your vibration and noise 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 and noise accessories.
Plan your work schedule to spread any high vibration tool
use across a number of days.

TROUBLE SHOOTING
1. I CAN NOT FIT THE BATTERY INTO THE BATTERY
CHARGER. WHY?
The battery can be inserted into the charger only in one
direction. Turn the battery around until it can be inserted
into the slot.
2. REASONS FOR DIFFERENT BATTERY PACK WORKING
TIMES
Charging time problems, as above, and having not used a
battery pack for a prolonged time will reduce the battery
pack working time. This can be corrected after several
charge and discharge operations by charging & working
with your drill. Heavy working conditions such as large
screws into hard wood will use up the battery pack energy
faster than lighter working conditions. Do not re-charge
your battery pack below 0oC and above 40oC as this will
affect performance.
MAINTENANCE
Remove the battery pack from the tool before
carrying out any adjustment, servicing or
maintenance.
Your power tool requires no additional lubrication or
maintenance.
There are no user serviceable parts in your power tool.
Never use water or chemical cleaners to clean your power
tool. Wipe clean with a dry cloth. Always store your power
tool in a dry place. Keep the motor ventilation slots clean.
Keep all working controls free of dust. Occasionally you
may see sparks through the ventilation slots. This is
normal and will not damage your power tool.
FOR BATTERY TOOLS
The ambient temperature range for the use and storage
of tool and battery is 0oC-45oC.
The recommended ambient temperature range for the
charging system during charging is 0oC-40oC.
