3) Personal safety
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.
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 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.
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.
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.
4) Power tool use and care
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 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 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 accidentall
y.
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.
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.
Keep cutting tools sharp and clean. Properly maintained
Danger!
When using the equipment, a few safety precautions must be
observed to avoid injuries and damage. Please read the
complete operating instructions and safety regulations with
due care. Keep this manual in a safe place, so that the
information is available at all times. If you give the equipment
to any other person, hand over these operating instructions
and safety regulations as well. We cannot accept any liability
for damage or accidents which arise due to a failure to follow
these instructions and the safety instructions.
1. GENERAL POWER TOOL SAFETY
WARNING
WARNING!
Read and understand 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.
1) Work area safety
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 flammable liquids, gases or
dust. Power tools create sparks which may ignite the dust
or fumes.
Keep children and bystanders away while operating a
power tool. Distractions can cause you to lose control.
2) Electrical 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.
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.
3

cutting tools with sharp cutting edges are less likely to bind
and are easier to control.
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.
5) Service
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.
6) Battery tool use and care
a. Ensure the switch is in the off position before inserting
battery pack. Inserting the battery pack into power tools
that have the switch on invites accidents.
b. 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.
c. Use power tools only with specifically designated battery
packs. Use of any other battery packs may create a risk of
injury and fire.
d. 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.
e.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.
ADDITIONAL SAFETY INSTRUCTIONS FOR BATTERY
CHARGING
Before charging, read the instructions.
Recharge only with USB power supply-5V DC.
Do not charge a leaking battery.
Do not use chargers for works other than those for which
they are specified.
The charging device must be protected from moisture.

ADDITIONAL POWER TOOL SAFETY WARNINGS
Warning! Additional safety warnings for screwdrivers:
Hold power tool by insulated gripping surfaces, when
performing an operation where the fastener may contact
hidden wiring. Fasteners contacting a "live" wire may
make exposed metal parts of the power tool "live" and
could give the operator an electric shock.
Use clamps or another practical way to secure and support
the workpiece to a stable platform. Holding the work by
hand or against your body leaves it unstable and may lead
to loss of control.
