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
• Wear ear protectors. Exposure to noise can cause
hearing loss�
• Use auxiliary handle(s), if supplied with the tool.
Loss of control can cause personal injury�
• Hold power tool by insulated gripping surfaces,
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
Notice the supply power voltage: in power con-
nection, be sure to note whether the power supply
voltage is the same as that labeled on the tool name-
plate� When the power supple voltage is higher than
the voltage applicable to the tool, an accident will
happens to the user and meanwhile the tool itself will
be destroyed� Therefore, in case of the failure to con-
firm the power supply voltage, never plug in arbitrar-
ily� On the contrary, when the power supply voltage
is lower than that needed for the tool, the motor will
be damaged�
Safety guidelines during
power tool operation
All instructions have to be read� In case of
using the machine not in accordance with
the following provisions, electric shock, fire
or serious injury may occur�
• Check that the drill bit has been clamped in proper
position or not prior to operation�
• Power tool working will generate vibration and you
should carefully confirm that screws in different places
still are tightened or not prior to operation�
• Wear blinder in operation to protect eyes�
• Maintain the keenness of the drill bit so as to achieve
the optimum and safest efficiency.
• When replace or assemble the accessories, the op-
eration must follow the instructions of the accessory
strictly�
• If the productor has any problems, you must not try
to repair personally, please take it to the local assigned
maintenance center for inspection�
• Fix the workpiece as far as possible� The workpiece
shall be fixed with fixing device or pincer pliers, which
shall be fastness than holding the piece in hand�
• Before powered on, the switch must be confirmed
in "off" position; before you put down the power tool, it
must be turned off and the power plug must be pulled
out�
• When the accessory is totally static, then the power
tool can be put down�
• Never let the power wire touch the drill bit or sur-
rounding parts in operation, or the power wire may be
damaged� The power tool with broken wires must not
be used� If the power wire is damaged in the work-
ing, then the damaged wire must not be touched, and
the plug must be pulled out immediately� The dam-
aged wire shall increase the danger of user's electric
shock�
• Chiseling walls, floors or on similar occasions, pay
attention to keep away from gas, tap water pipeline
and electric wire and operating tools in those places
shall keep away from touching metal parts� The appro-
priate detector shall be used so as to find out the loca-
tion of the concealed power wire� Or you can require
the relevant data from the local power supply entity�
The wires that are drilled through shall result in the fire
and electric shock� The damaged gas pipe will resulted
in the explosion� If the water pipe is drilled through, the
property loss will be caused�
• If the accessory installed on the power tool gets
clamped, the power tool must be turned off immedi-
ately and stay calm� At the time, the power tool will
generate ultra-high reaction torque, and result in the
return stroke� The accessory installed on the power
