power tool, if they are not supervised or instructed
about use of the power tool by a person responsible
for their safety�
• 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 the battery pack from the power tool be-
fore making any adjustments, changing accesso-
ries, 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 chil-
dren 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. Check for misalignment or
binding of moving parts, breakage of parts and any
other condition that may affect the power tool's op-
eration. 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 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 hazard-
ous 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�
• Note that when you operate a power tool, please
hold the auxiliary handle correctly, which is helpful
when controlling the power tool� Therefore, proper
holding can reduce the risk of accidents or injuries�
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�
• Follow instruction for lubricating and changing ac-
cessories�
safety warnings
•
Use auxiliary handle(s), if supplied with the tool.
Loss of control can cause personal injury�
• Hold power tool by insulated gripping sur-
faces, when performing an operation where the
cutting accessory may contact hidden wiring or
its own cord. Cutting accessory contacting a "live"
wire may make exposed metal parts of the power
tool "live" and could give the operator an electric
shock�
Special
Safety guidelines during
power tool operation
•
The workpiece shall be fastened� Fixed devices or
vice shall be used to fasten the workpiece, which will
be more secure than holding the workpiece with your
hands�
• Considering that asbestos may cause cancer, as-
bestos-containing materials shall not be processed�
• The power tool could be put down only after the
parts of power tool is completely static� Accessory on
the power tool might be clamped during work, which
may make it difficult for you to control the power tool.
• Power tool with damaged electric wires shall not be
used� If electric wires of the power supply are dam-
aged during the work, you shall not touch the damaged
electric wires and shall pull out the plug immediately�
Damaged electric wires will raise the risk of electric
shock�
• When using power tools outdoor, you must install
fault current (FI) protection switch on the power tool�
• Appropriate detector shall be used to find the loca-
tion of hidden power wires� Or you should obtain rel-
evant information from local power supply unit� Drilling
electric wires will cause fire and electric shock. Dam-
aged gas pipe will cause exploration� If water pipes are
punctured, damage will be caused to property�
• In case a accessory installed on the power tool is
clamped, you shall shut down the power tool and stay
calm� At that time, the power tool will produce extreme-
ly high reactive torque thus resulting in return stroke�
The accessory installed on the power tool are likely to
be clamped, for example: hypercharge of power tool or
skewing of accessory installed on the power tool dur-
ing work�
• If hidden electric wires or power lines of the power
tool itself might be cut off during work, you must hold
the insulated handle to operate the power tool� When
the power tool is in touch with a charged line, the metal
parts on the power tool will conduct electricity and may
cause the operator to get an electric shock�
• During work, you must tightly hold the power tool
and ensure you stand firmly. You should hold the pow-
er tool with your hands�
• When operating and using the power tool, you can
only hold switch position of the main handle rather than
other parts�
• Avoid stopping an power tool motor when loaded�
• Never remove any chips or fragments with your
power tool's motor running�
• When working, follow the position of the power
supply cable� Avoid winding it around your legs or
arms�
• Use only sharp drill bits without defects - it will make
working with the power tool easier�
• The modification of the drill bits design and the use
of removable orifices and accessories not envisaged
for this power tool is strictly forbidden�
• Do not apply excessive pressure when operating the
power tool - it can jam the drill bit and overload the
engine�
• Do not allow drill bits to jam in the material pro-
cessed� If this occurs, do not try to release them by
means of the power tool engine� This can put the pow-
er tool out of order�
• Striking out drill bits jammed in the material pro-
cessed with a hammer or other objects is strictly for-
