02 How to Use
Press the ∨ end to turn in or tighten screws.
Press the ∧ end to loosen or remove screws.
Forward/Reverse rotation buon
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.
Aer 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 aached by the magnetic force.
How to Use the Screwdriver
When the bit magnetism is insufficient, 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 baery level is below 20% when the screwdriver is in
use, the indicator will blink red quickly for 5 seconds, and it
will turn off when the buon is released. Please charge the
baery in time.
When charging, the indicator will slowly blink red.
When the baery is fully charged, the indicator will stay white.

04 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 baery-operated (cordless) power tool.
Keep work area clean and well lit. Cluered or dark areas invite accidents.
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.
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. Unmodified
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
6
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
influence of drugs, alcohol or medication. A moment of inaention 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 off-position before
connecting to power source and/or baery 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.
Remove any adjusting key or wrench before turning the power tool on. A
wrench or a key le aached 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
beer control of the power tool in unexpected situations.
Personal Safety
7
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 beer 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 off. 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 baery 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
8
Recharge only with the charger specified by the manufacturer. A charger that
is suitable for one type of baery pack may create a risk of fire when used with
another baery pack.
Use power tools only with specifically designated baery packs. Use of any
other baery packs may create a risk of injury and fire.
When baery 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 baery
terminals together may cause burns or a fire.
Under abusive conditions, liquid may be ejected from the baery; avoid
contact. If contact accidentally occurs, flush with water. If liquid contacts
eyes, additionally seek medical help. Liquid ejected from the baery may
cause irritation or burns.
Baery 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 affect 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 different 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.
9
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.
Never service damaged baery packs. Service of baery packs should only be
performed by the manufacturer or authorized service providers.
Service
Do not use a baery pack or tool that is damaged or modified. Damaged or
modified baeries may exhibit unpredictable behavior resulting in fire,
explosion or risk of injury.
Do not expose a baery pack or tool to fire or excessive temperature.
Exposure to fire or temperature above 130°C may cause explosion.
Follow all charging instructions and do not charge the baery pack or tool
outside the temperature range specified in the instructions.
Charging
improperly or at temperatures outside the specified range may damage the
baery and increase the risk of fire.
Hold the power tool by insulated gripping surfaces, when performing an
operation where the cuing accessory or fasteners may contact hidden
wiring. Cuing 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
10
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 off 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
fire and electrical shock. Damaging gas lines can lead to explosion. Breaking water
pipes causes property damage.
Additional safety information
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 baery, vapours may be emied.
The baery can set alight or explode. Ensure the area is well ventilated and seek
medical aention should you experience any adverse effects. The vapours may
irritate the respiratory system.
Do not open the baery. There is a risk of short-circuiting.
The baery can be damaged by pointed objects such as nails or screwdrivers
or by force applied externally. An internal short circuit may occur, causing the
baery to burn, smoke, explode or overheat.
Only use the baery with products from the manufacturer. This is the only way
in which you can protect the baery against dangerous overload.
Protect the baery against heat, e.g. against continuous intense sunlight, fire,
dirt, water and moisture. There is a risk of explosion and short-circuiting.
