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.

4
20V Cordless Impact Drill WX352 WX352.X
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.
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.
DRILL SAFETY WARNINGS
1) Safety instructions for all operations
a) Wear ear protectors when impact drilling.
Exposure to noise can cause hearing loss.
b) Hold the power tool by insulated gripping
surfaces, when performing an operation
where the cutting accessory or fasteners
may contact hidden wiring.
Cutting
accessory or fasteners contacting a “live” wire
may make exposed metal parts of the power
tool “live” and could give the operator an
electric shock.

5
20V Cordless Impact Drill WX352 WX352.X
2) Safety instructions when using long drill
bits
a) Never operate at higher speed than
the maximum speed rating of the drill
bit. At higher speeds, the bit is likely to
bend if allowed to rotate freely without
contacting the workpiece, resulting in
personal injury.
b) Always start drilling at low speed and
with the bit tip in contact with the
workpiece. At higher speeds, the bit is
likely to bend if allowed to rotate freely
without contacting the workpiece,
resulting in personal injury.
c) Apply pressure only in direct line with the
bit and do not apply excessive pressure.
Bits can bend causing breakage or loss of
control, resulting in personal injury.
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 with
the skin or eyes. If contact has been made,
wash the affected area with copious
amounts of water and seek medical
advice.
f) Keep battery pack clean and dry.
g) Wipe the battery pack terminals with a
clean dry cloth if they become dirty.
h) Battery pack needs to be charged before

ah,D = 2.151 m/s
Uncertainty K = 1.5 m/s
Impact drilling into
concrete
Vibration emission value ah,ID =
10.712 m/s
Uncertainty K = 1.5 m/s
The declared vibration total value and the declared noise
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.

20V Cordless Impact Drill WX352 WX352.X
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.

LED light indicator (See Fig. G)
Before operation, the LED light will be activated
when the On/Off switch is slightly depressed, and
will automatically turn off 20 seconds after the On/
Off switch is released.
WARNING: To turn on the light, press the On/
Off switch and make sure the Forward/
Reverse Rotation Control is on right/left position.
The tool and battery are equipped with a protection
system. When the LED Light is quickly flashing 60
seconds and turn off, the system will automatically
cut off power to the tool to extend battery life. The
tool will automatically stop during operation if the
tool and/or battery are placed under one of the
following conditions:
• Overloaded: The tool is operated in a manner
that causes it to draw an abnormally high current.
In this situation, release the Trigger Switch on the
tool and stop the application that caused the tool
to become overloaded. Then pull the Trigger Switch
again to restart.
• Overheated: Under the condition above, if
the tool does not start, the Tool and Battery are
overheated. In this situation, let the Tool and Battery
cool before pulling the Trigger Switch again.
• Low battery voltage: The remaining Battery
capacity is too low and the tool will not operate. In
this situation, remove and recharge the Battery.
PROBLEM SOLUTION
1. WHY DOES THE DRILL NOT TURN ON WHEN
YOU PRESS THE SWITCH?
The Forward and Reverse Switch, which is on top
of the trigger, is positioned in the lock function.
Unlock the Forward and Reverse Switch putting
it into the required rotation position. Push the
trigger and the drill will start to rotate (See Fig.
B).
2. THE DRILL STOPS BEFORE THE SCREW IS
COMPLETELY TIGHTENED. WHY?
Verify the torque position of the Torque

14
20V Cordless Impact Drill WX352 WX352.X
Adjustment Ring, you can find the Torque
Adjustment Ring between the Chuck and the
drill body. Position 1 is the lowest torque (screw
driving force) and position 22 is the highest
torque (screw driving force). Position is for
drill operation. Position is for hammer drill
operation. Regulate the Torque Adjustment Ring
to a higher position to reach the best result (See
Fig. E).
3. 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, the red LED Light
should turn on when the battery is charging.
4. 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.
ENVIRONMENTAL
PROTECTION
Waste electrical products must not be
disposed of with household waste. Please
recycle where facilities exist. Check with
your local authorities or retailer for recycling
advice.
