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 and 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.
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 safety 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 offposition 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
2
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, 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 these devices 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.

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, ceramic 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 chuck 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 is charged for the first time and after prolonged
storage, the battery will only accept approximately 60% charge.
However, after several charge and discharge cycles the battery will
accept a 100% charge.
B) TO REMOVE OR INSTALL BATTERY PACK (See Fig.A)
Press the battery pack latch and remove the battery pack from the
drill. After recharge slide the battery pack into drill’s battery port. A
simple push and slight pressure will be sufficient.

Slide the handle onto the drill and rotate it to the desired working
position. To clamp the auxiliary handle, rotates the handgrip
clockwise. To loosen it, rotate the handgrip anti-clockwise. Always
use the handle during operation.
ON/OFF SWITCH (See Fig.C)
2
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.
SWITCH LOCK (See Fig.C)
3
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.
REVERSIBLE ( See Fig.C)
4
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!

TWO-SPEED GEAR CONTROL (See Fig.D)
5
The drill has a two- speed gear control designed for drilling or driving
at LOW (mark is 1) or HIGH ( mark is 2) speeds. A slide switch is
located on top of the drill to select either LOW or HIGH speed. When
using the drill in the LOW speed range, the speed will decrease and
the drill will have greater power and torque. When using the drill in
the HIGH 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.
CHUCK ADJUSTMENT (See Fig.E)
6
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.
TORQUE ADJUSTMENT AND HAMMER OR DRILLING

circumstances. To turn on the light simply press the on/off switch.
When you release the on/ off switch, the light will be off.
AUTOMATIC SPINDLE LOCK (See Fig.G)
9
The automatic spindle lock allows you to use the drill 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.

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 screwdriving, apply a small quantity of liquid soap or similar to the
screw threads to ease insertion.
Problem solution
WHY DOES THE HAMMER DRILL NOT TURN ON WHEN YOU
1
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 hammer 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 20 is the
highest torque ( screw driving force). Position 21 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, 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.
13
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.
