GENERAL POWER TOOL
SAFETY WARNINGS
WARNING: Read all safety warnings
and 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 grounded power tools.
Unmodified plugs and matching outlets
will reduce risk of electric shock.
b) Avoid body contact with 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 Ground Fault Circuit Interupter
(GFCI) protected supply. Use of a
GFCI 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 energizing 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 jewelry. Keep your hair,
clothing and gloves away from
moving parts. Loose clothes, jewelry or
long hair can be caught in moving parts.
g) If devices are provided for the

3
Lithium-Ion
cordless drill/driver WX125 WX125.1
WX125.4
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 tools 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 and in the
manner intended for the particular
type of power tool, 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) 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.
ADDITIONAL SAFETY
RULES FOR YOUR
CORDLESS DRILL
1. Wear ear protectors with cordless
drills. Exposure to noise can cause
hearing loss.
2. Always hold the tool with both
hands. Loss of control can cause
personal injury.

4
Lithium-Ion
cordless drill/driver WX125 WX125.1
WX125.4
3. Hold tool by insulated gripping
surfaces when performing an
operation where the cutting tools
may contact hidden wiring. Contact
with a “live” wire make exposed metal
parts of the tool “live” and shock the
operator.
4. Always wear safety goggles or eye
protection when using this tool.
Use a dust mask or respirator for
applications which generate dust.
5. Secure the material being drilled. Never
hold it in your hand or across legs.
Unstable support can cause the drill bit to
bind causing loss of control and injury.
6. Disconnect battery pack from tool
or place the switch in the locked
or off position before making any
assembly, adjustments or changing
accessories. Such preventive safety
measures reduce the risk of starting the
tool accidentally.
7. Position yourself to avoid being
caught between the tool or side
handle and walls or post. Should the
bit become bound or jammed in the work,
the reaction torque of the tool could crush
your hand or leg.
8. If the bit becomes bound in the
workpiece, release the trigger
immediately, reverse the direction
of rotation and slowly squeeze the
trigger to back out the bit. Be ready
for a strong reaction torque.The drill body
will tend to twist in the opposite direction
as the drill bit is rotating.
9. Do not grasp the tool or place your
hands too close to the spinning
chuck or drill bit. Your hand may be
lacerated.
10. When installing a drill bit, insert the
shank of the bit well within the jaws
of the chuck. If the bit is not inserted
deep enough, the grip of the jaws over
the bit is reduced and the loss of control
is increased.
11. Do not use dull or damaged bits
and accessories. Dull or damaged bits
have a greater tendency to bind in the
workpiece.
12. When removing the bit from the
tool avoid contact with skin and
use proper protective gloves when
grasping the bit or accessory.
Accessories may be hot after prolonged use.
13. Check to see that keys and adjusting
wrenches are removed from the drill
before switching the tool “ON”. Keys
or wrenches can fly away at high velocity
striking you or bystander.
14. Do not run the dill while carrying it
at your side. A spinning drill bit could
become entangled with clothing and
injury may result.
15. Avoid bouncing and snagging the
wheels, discs or brushes especially
when working corners, sharp edges,
etc. This can cause loss of control and
kickback.
16. Position the tether clear of rotating
bit. Do not wrap the tether around
your arm or wrist. If you lose control
and have the tether wrapped around your
arm or wrist, it may entrap you and cause
injury.
WARNING: If a small amount
of electrolyte should leak from
the battery pack under extremes of
temperature or after heavy use, then
wash off immediately from your skin and
hands using clean water. For eye contact,
rinse thoroughly with clean water and seek
medical treatment immediately.

OPERATING INSTRUCTIONS
NOTE: Before using the tool, read the instruction
book carefully.
INTENDED USE
The machine is intended for driving in and loosening
screws as well as for drilling in wood, metal and plastic.
BEFORE PUTTING INTO OPERATION
A) CHARGING THE BATTERY
The battery charger supplied is matched to the Li-ion
battery installed in the machine. Do not use another
battery charger.
The Li-ion battery is protected against deep discharging.
When the battery is empty, the machine is switched
off by means of a protective circuit:The tool holder no
longer rotates.
In a warm environment or after heavy use, the battery
pack may become too hot to permit charging. Allow
time for the battery to cool down before recharging.
When the battery pack is charged for the first time and
after prolonged storage, the battery pack will accept a
100% charge after several charge and discharge cycles.
B) TO REMOVE OR INSTALL BATTERY PACK
(See Fig.A)
Depress the battery pack release button to release and
slide the battery pack out from your tool. After recharge,
slide it back into your tool. A simple push and slight
pressure will be sufficient.
OPERATION
1. ON / OFF SWITCH (See Fig.B)
Depress the On/Off switch to start and release it to stop
your drill.The on/off switch is fitted with a brake function
which stops your chuck immediately when you quickly
release the switch.
It is also a variable speed switch that delivers higher
speed and torque with increased trigger pressure.
Speed is controlled by the amount of switch trigger
depression.
WARNING: Do not operate for long periods
at low speed because excess heat will be
produced internally.
2. SWITCH LOCK
The switch trigger can be locked in the OFF position.
This helps to reduce the possibility of accidental starting
when not in use.To lock the switch trigger, place the
rotation control in the center position.

WX125.4
3. REVERSIBLE (See Fig.B)
For drilling and screw driving use forward rotation
marked “ ” (lever is moved to the left). Only use
reverse rotation marke“ ” (lever is moved to the
right) to remove screws or release a jammed drill bit.
WARNING: Never change the direction of
rotation when the chuck is rotating, wait
until it has stopped!
4. TWO-SPEED GEAR CONTROL (See Fig.C)
The drill has a two-speed gear control designed for
drilling or driving at LO (mark is 1) or HI (mark is 2)
speeds. A slide switch is located on top of the drill to
select either LO or HI speed. When using the drill in the
LO speed range, the speed will decrease and the drill
will have greater power and torque. When using the drill
in the HI speed range, the speed will increase and the
drill will have less power and torque.
Gear I
Low speed range: for screwdriving or working with
large drilling diameter
Gear II
High speed range: for working with small drilling diameter
WARNING: To prevent gear damage, always
allow the chuck to come to a complete stop
before changing the direction of rotation or the
two-speed gear control.
5. CHUCK ADJUSTMENT (See Fig.D)
To open the chuck jaws rotate the front section of the
chuck. Insert the drill bit between the chuck jaws and
rotate the front section in the opposite direction. Ensure
the drill bit is in the center of the chuck jaws. Finally,
firmly rotate the front chuck section in the opposite
directions.Your drill bit is now clamped in the chuck.
6. TORQUE ADJUSTMENT (See Fig.E)
(Screw driving force of your drill driver)
The torque is adjusted by rotating the torque adjustment
ring.The torque is greater when the torque adjustment
ring is set on a higher setting.The torque is less when
the torque adjustment ring is set on a lower setting.
Make the setting as follows:
1 - 4 for driving small screws
5 - 9 for driving screws into soft
material
10 - 15 for driving screws into soft and hard material
for heavy drilling

7. AUTOMATIC SPINDLE LOCK (See Fig.F)
The automatic spindle lock allows you to use it as a
regular screwdriver.You can give an extra twist to firmly
tighten a screw, loosen a very tight screw or continue
working when the battery energy has expired. For
manual screwdriver purposes, the chuck is automatically
locked when the tool is off.
8. USING THE LED LIGHT
To turn on the light simply press the on/off switch. When
you release the on/off switch, the light will be off.
LED lighting increases visibility-great for dark or
enclosed area. LED is also a battery capacity indicator. It
will flash when power gets low.
9. DRILLING
When drilling into a hard smooth surface, use a center
punch to mark the desired hole location.This will
prevent the drill bit from slipping off center as the hole
is started. Hold the tool firmly and place the tip of the
bit at the point to be drilled. Depress the switch trigger
to start the tool. Move the drill bit into the workpiece,
applying only enough pressure to keep the bit cutting.
Do not force or apply side pressure to elongate a hole.
Tungsten carbide drill bits should always
be used for concrete and masonry. When
drilling in metal, only use HSS drill bits in good
condition. Always use a magnetic bit holder (not
included) when using short screwdriver bits.
When screw-driving, apply a small quantity of
liquid soap or similar to the screw threads to
ease insertion.
10. OVERLOAD PROTECTION
When overloaded, the motor comes to a stop. Relieve
the load on the machine immediately and allow cooling
for approx. 30 seconds at the highest no-load speed.
11. TEMPERATURE DEPENDENT OVERLOAD
PROTECTION
When using as intended for the power tool cannot be
subject to overload. When the load is too high or the
allowable battery temperature of 75°C is exceeded, the
electronic control switches off the power tool until the
temperature is in the optimum temperature range again.
12. PROTECTION AGAINST DEEP DISCHARGING
The Li-ion battery is protected against deep discharging
by the “Discharging Protection System”. When the
battery is empty, the machine is switched off by means

11
Lithium-Ion
cordless drill/driver WX125 WX125.1
WX125.4
of a protective circuit:The inserted tool no
longer rotates.
PROBLEM SOLUTION
1. WHY DOES THE DRILL NOT TURN ON
WHEN YOU PRESS THE SWITCH?
The forward/reverse rotation control, which is
on top of the trigger, is positioned in the lock
function. Unlock the forward/reverse rotation
control by putting it into the required rotation
position. Push the trigger and the drill will
start to rotate.
2. THE DRILL STOPS BEFORE THE
SCREW IS COMPLETELY TIGHTENED.
WHY?
Verify the torque position of the torque
adjusting ring, you can find the torque-
adjusting ring between the chuck and the drill
body. Position 1 is the lowest torque (screw
driving force) and position 15 is the highest
torque (screw driving force). Position “16”
is for drill operation. Regulate the torque
adjusting ring to a higher position to reach the
best result.
3. 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 45oC as this will affect
performance.
MAINTENANCE
Your 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.
