02 How to Use
Press the ∨end to turn in or tighten screws.
Press the ∧end to loosen or remove screws.
Forward/Reverse rotation button
Bits are stored in the base magnetically. The
screwdriver bit is removed from a storage box, and
the bit is inserted into the bit holder.
After the bit is inserted into the bit holder, it is
magnetized in the middle magnetizing area.
Magnetic force can be generated, and most screws
can be attached by the magnetic force.
How to Use the Screwdriver
When the bit magnetism is insucient, the bit can be
magnetized in time by placing the bit top at the
magnet of the receiving tank for 5S. The magnetic
force of the bit will decrease when stored for a long
time, so the bit should be regularly magnetized.
Magnetizing
If the battery level is below 20% when the screwdriver is in use,
the indicator will blink red quickly for 5 seconds, and it will turn o
when the button is released. Please charge the battery in time.
When charging, the indicator will slowly blink red.
When the battery is fully charged, the indicator will stay white.

04 General Power Tool Safety Warnings
19
WARNING! Read all safety warnings, instructions, illustrations and specications provided
with this power tool. Failure to follow all instructions listed below may result in electric
shock, re 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.
Keep work area clean and well lit. Cluttered or dark areas invite accidents.
Do not operate power tools in explosive atmospheres, such as in the presence of
ammable liquids, gases or dust. Power tools create sparks which may ignite the dust
or fumes.
Keep children and bystanders away while operating a powertool. Distractions can
cause you to lose control.
Work Area Safety
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. Unmodied plugs and
matching outlets will reduce risk of electric shock.
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.
Do not expose power tools to rain or wet conditions. Water entering a power tool will
increase the risk of electric shock.
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.
Electrical safety

20
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.
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.
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 inuence of
drugs, alcohol or medication. A moment of inattention while operating power tools
may result in serious personal injury.
Use personal protective equipment. Always wear eye protection. Protective
equipment such as a dust mask, non-skid safety shoes, hard hat or hearing protection
used for appropriate conditions will reduce personal injuries.
Prevent unintentional starting. Ensure the switch is in the o-position before
connecting to power source and/or battery pack, picking up or carrying the tool.
Carrying power tools with your nger on the switch or energising power tools that
have the switch on invites accidents.
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.
Do not overreach. Keep proper footing and balance at all times. This enables better
control of the power tool in unexpected situations.
Personal Safety

21
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.
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.
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.
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.
Do not use the power tool if the switch does not turn it on and o. Any power tool
that cannot be controlled with the switch is dangerous and must be repaired.
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.
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.
Power Tool Use And Care

22
Recharge only with the charger specied by the manufacturer. A charger that is
suitable for one type of battery pack may create a risk of re when used with another
battery pack.
Use power tools only with specically designated battery packs. Use of any other
battery packs may create a risk of injury and re.
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 re.
Under abusive conditions, liquid may be ejected from the battery; avoid contact. If
contact accidentally occurs, ush with water. If liquid contacts eyes, additionally seek
medical help. Liquid ejected from the battery may cause irritation or burns.
Battery tool use and care
Maintain power tools and accessories. Check for misalignment or binding of moving
parts, breakage of parts and any other condition that may aect the power tool's
operation. If damaged, have the power tool repaired before use. Many accidents are
caused by poorly maintained power tools.
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 dierent from those intended could
result in a hazardous situation.
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.

23
Have your power tool serviced by a qualied repair person using only identical
replacement parts. This will ensure that the safety of the power tool is maintained.
Never service damaged battery packs. Service of battery packs should only be
performed by the manufacturer or authorized service providers.
Service
Do not use a battery pack or tool that is damaged or modied. Damaged or modied
batteries may exhibit unpredictable behavior resulting in re, explosion or risk of
injury.
Do not expose a battery pack or tool to re or excessive temperature.
Exposure to re or temperature above 130°C may cause explosion.
Follow all charging instructions and do not charge the battery pack or tool outside
the temperature range specied in the instructions.
Charging improperly or at
temperatures outside the specied range may damage the battery and increase the
risk of re.
Hold the power tool by insulated gripping surfaces, when performing an operation
where the cutting accessory or fasteners 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.
Safety instructions for all operations

24
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.
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.
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 instructions when using long drill bits
Secure the workpiece. A workpiece clamped with clamping devices
or in a vice is held more secure than by hand.
Always wait until the power tool has come to a complete stop before placing it down.
The application tool can jam and cause you to lose control of the power tool.
Switch the power tool o immediately if the application tool becomes blocked. Be
prepared for high torque reactions which cause kickback. The application tool
becomes blocked when it becomes jammed in the workpiece or when the power
tool becomes overloaded.
Use suitable detectors to determine if there are hidden supply lines or contact the
local utility company for assistance. Contact with electric cables can cause re and
electrical shock. Damaging gas lines can lead to explosion. Breaking water pipes causes
property damage.
Additional safety information

25
Hold the power tool securely. When tightening and loosening screws be prepared for
temporarily high torque reactions.
In case of damage and improper use of the battery, vapours may be emitted. The
battery can set alight or explode. Ensure the area is well ventilated and seek medical
attention should you experience any adverse eects. The vapours may irritate the
respiratory system.
Do not open the battery. There is a risk of short-circuiting.
The battery can be damaged by pointed objects such as nails or screwdrivers or by
force applied externally. An internal short circuit may occur, causing the battery to
burn, smoke, explode or overheat.
Only use the battery with products from the manufacturer. This is the only way in
which you can protect the battery against dangerous overload.
Protect the battery against heat, e.g. against continuous intense sunlight, re, dirt,
water and moisture. There is a risk of explosion and short-circuiting.
