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.

8
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
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

9
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.

10
DRILL SAFETY WARNINGS
1) Safety instructions for all operations
a) Wear ear protectors when impact drilling. Exposure
to noise can cause hearing loss.
b) Hold the power tool by insulated gripping surfaces,
when performing an operation where the cutting
accessory or fasteners may contact hidden wiring.
Cutting accessoryor fastenerscontacting a “live” wire
may make exposed metal parts of the power tool “live”
and couldgive the operator an electric shock.
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 cells.
b) Do not short-circuit charging terminal. Do not store
power tool haphazardly in a box or drawer where
charging terminal may short-circuit each other or
be short-circuited by conductive materials. 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 charging terminal to another.Shorting the battery
terminals together may cause burns or a fire.
c) Do not expose power tool to heat or fire. Avoid
storage in direct sunlight.
d) Do not subject power tool to mechanical shock.
e) In the event of battery leaking, do not allow the
liquid to come into contact with the skin or eyes.
If contact has been made, wash the affected area
with copious amounts of water and seek medical
advice.
f) Keep power tool clean and dry.
g) Wipe the charging terminals with a clean dry cloth
if they become dirty.
h) Battery pack needs to be charged before use.

The declared vibration total value and the declared noise
emission value have been measured in accordance with a
standard test method and may be used for comparing one
tool with another.
The declared vibration total valueand the declared
noise emission valuemay also be used in a preliminary
assessment of exposure.
WARNING: The vibration and noise emissions
during actual use of the power tool can differ from
the declared value depending on the ways in which the
tool is used especially what kind of workpiece is
processeddependant on the following examples and other
variationson how the tool is used:

16
How the tool is used and the materials being cut or drilled.
The tool being in good condition and well maintained.
The use ofthe 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 and noise 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 minimise your vibration and noise 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 and noise accessories.
Plan your work schedule to spread any high vibration tool
use across a number of days.

OPERATING THE ON/OFF SWITCH
WARNING Do not operate
for long periods at low speed
because excess heat will be produced
internally.
See Fig. G
LED LIGHT INDICATOR (See Fig. G)
To turn on the light, press the on/off switch and make sure
the forward/reverse rotation control is on right/left position.
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.
The tool and battery pack are equipped with a protection
system. When the LED Light is quickly flashing 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 pack 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 Pack are overheated. In this
situation, let the Tool and Battery Pack 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 Pack.
6.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.Check that the battery is charged and
properly connected to the tool.

18
(2)THE DRILL STOPS BEFORE THE SCREW IS
COMPLETELY TIGHTENED. WHY?
Verify the torque position of the torque adjusting ring.
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 is for drill operation. Regulate the torque
adjusting ring to a higher position to reach the best result.
(3)I CAN NOT FIT THE BATTERY PACK INTO THE
BATTERY CHARGER. WHY?
The battery pack can be inserted into the charger only in
one direction. Turn the battery pack around until it can be
inserted into the slot. The charger LED indicator should
turn on when the battery pack 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 45oC as this will
affect performance.
7.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 tool and battery use
and storage is 0℃-45℃.
The recommended ambient temperature range for the
charging system during charging is 0℃-40℃.
8.ENVIRONMENTAL PROTEC
TION
Waste electrical products must not be disposed
of with household waste. Please recycle where
facilities exist. Check with your local authorities or
retailer for recycling advice.
