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

5
EN
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.
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) 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.

6EN
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 battery pack.
b) Do not expose battery pack to heat or fire. Avoid
storage in direct sunlight.
c) 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 other metal objects. 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 fire.
d) Do not remove battery pack from its original
packaging until required for use.
e) Do not subject battery pack to mechanical shock.
f) In the event of battery leaking, do not allow the
liquid to come in contact with the skin or eyes. If

sufficient force until it clicks into position.
OPERATION
1. ON / OFF SWITCH (SEE FIG. C)
Depress the On/Off switch to start and release it to stop
your drill.

10 EN
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. When overload occurs, release
the on/off switch immediately to avoid the motor
overheating.
2. SWITCH LOCK (SEE FIG. C)
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.
3. REVERSIBLE (SEE FIG. D1, D2)
For drilling and screw driving use forward rotation
marked “ ” (lever is moved to the left of the drill)
(D1). Only use reverse rotation marked “ ” (lever is
moved to the right of the drill) (D2) 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. CHUCK ADJUSTMENT (SEE FIG. E)
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.
5. TORQUE ADJUSTMENT (SEE FIG. F)
(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 - 14 for driving screws into soft and hard material
15 - 19 for driving screws into hard wood
20 - 21 for driving larger screws
for heavy drilling
6. AUTOMATIC SPINDLE LOCK
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.
7. USING THE LED LIGHT
To turn on the LED 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.
8. 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.
WARNING: 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
when using short screwdriver bits. When screw-
driving, apply a small quantity of liquid soap or
similar to the screw threads to ease insertion.
9. DISPOSAL OF AN EXHAUSTED BATTERY PACK
To preserve natural resources, please recycle or
dispose of the battery pack properly. This battery
pack contains Lithium batteries. Consult your
local waste authority for information regarding available
recycling and/or disposal options. Discharge your
battery pack by operating your drill, then remove the
battery pack from the drill housing and cover the battery
pack connections with heavy-duty adhesive tape to
prevent short circuit and energy discharge. Do not
attempt to open or remove any of the components.
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

11
EN
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
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 21 is the highest
torque (screw driving force). Position 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
Remove the battery pack from the tool before
carrying out any adjustment, servicing or
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.
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.
