VIBRATION INFORMATION
Vibration total values (triax vector sum) determined according to EN 60745:
Impact drilling into concrete
Drilling into metal
Vibration emission value ah,ID = 11.0m/s²
Uncertainty K = 1.5m/s²
Vibration emission value ah,D = 2,8m/s²
Uncertainty K = 1.5m/s²
The declared vibration total value may be used for comparing one tool with another, and may
also be used in a preliminary assessment of exposure.
6
WARNING: The vibration emission value during actual use of the power tool can differ
from the declared value depending on the ways in which the tool is used 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 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 accessories are used.
And the tool is being used as intended by its design and these instructions.
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 minimize your vibration 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 accessories.
Avoid using tools in temperatures of 100C or less.
Plan your work schedule to spread any high vibration tool use across a number of days.

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.
8
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, 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.
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.
DRILL SAFETY WARNINGS
1.Wear ear protectors when impact
drilling. Exposure to noise can cause
hearing loss.
2.Use auxiliary handles, If supplied
with the tool. Loss of control can cause
personal injury.
3.Hold power tool by insulated
gripping surfaces, when performing
an operation where the cutting
accessory may contact hidden
wiring. Cutting accessory contacting a
“live” wire may make exposed metal parts
of the power tool “live” and could give the
operator an electric shock.

LED LIGHT INDICATOR (See Fig. G)
Before operation, the LED light will be activated when the On/Off switch is slightly depressed
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.
WARNING: To turn on the light, press the On/Off switch and make sure the Forward/Reverse
Rotation Control is on right/left position.
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.C1 C2 C3).
2. THE DRILL STOPS BEFORE THE
SCREW IS COMPLETELY TIGHTENED.
WHY?
Verify the torque position of the Torque
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 30oC 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
