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.
WORK AREA SAFETY
1
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.
ELECTRICAL SAFETY
2
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.
PERSONAL SAFETY
3
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.
3
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
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.

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
• CHARGING THE BATTERY
The battery charger supplied is matched to the Li-ion battery
installed in the machine. Do not use another batter y 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.
• TO REMOVE OR INSTALL BATTERY PACK (See 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 B)
Depress the On/Off switch to start and release it to stop your drill.
10
The on/off switch is fitted with a brake function which stops your
A B
C D
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.
3
REVERSIBLE ( See B)
For drilling and screw driving use forward rotation marked “ ”
(lever is moved to the left). Only use reverse rotation marked
“ ” (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 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.
11
Gear I

E F
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 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 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
12
AUTOMATIC SPINDLE LOCK (See F)
F
7
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.
USING THE LED LIGHT
8
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 batter y capacity indicator. It will flash when power gets low.
DRILLING
9
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 screwdriving, apply a small quantity of liquid soap or similar to the
screw threads to ease insertion.

10
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.
11
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.
12
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.
13
PROTECTION AGAINST DEEP DISCHARGING
The Li-ion battery is protected against deep discharging by the
“Discharging Protection System”. When the batter y is empty, the
machine is switched off by means of a protective circuit: The inserted
tool no longer rotates.
Problem solution
WHY DOES THE DRILL NOT TURN ON WHEN YOU PRESS THE
1
SWITCH?
The forward/reverse rotation control, which is on top of the trigger, is
positioned in the lock function. Unlock the for ward/reverse rotation
control by putting it into the required rotation position. Push the
trigger and the drill will start to rotate.
THE DRILL STOPS BEFORE THE SCREW IS COMPLETELY
2
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 is for drill operation.
Regulate the torque adjusting ring to a higher position to reach the
best result.
REASONS FOR DIFFERENT BATTERY PACK WORKING TIMES
3
Charging time problems, as above, and having not used a battery
pack for a prolonged time will reduce the batter y 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.
