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�
Special 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�
Notice the supply power voltage: in power
connection, be sure to note whether the power
supply voltage is the same as that labeled on the tool
nameplate� 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 confirm the power supply voltage, never plug in
arbitrarily� 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
operation 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
surrounding 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
working, then the damaged wire must not be touched,
and the plug must be pulled out immediately� The
damaged 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 appropriate
detector shall be used so as to find out the location
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
immediately 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
tool is easy to be clamped, like: the power tool is in
hypercharge, or the accessory installed on the power
tool inclines in the workpiece�
• The concealed electric wire or the power wire of the
power tool may be cut off in operation, and then the
insulated handle must be held to operate the power
tool� If the power tool contacts the charged circuit,
then the metal parts on the power tool shall conduct
electricity, and the operator may have electric shock�
• Two handles of the productor must be held with
both hands tightly in operation, and the base must be
stable� Both hands can hold the power tool stably; one
hand operation must be avoided�
• The flat chisel must not be used in the rotational state
(such as rotary drill and hammer drill), or the chisel will
be blocked and the power tool will lose control�
• Only when you wear gloves then you can touch the
accessories, the drill bits and accessories will be hot in
operation, and it is easy to get burn� Never immediately
touch the drill bit or parts around it upon the end of
work, for those parts will be scalding and scald your
skin� Wear gloves and middle rest can reduce the
vibration and the injury to the hands and arms�
• Hands and body must not be placed between the
power tool and the wall or column so as to prevent
the power tool from flying off when the drill bits gets
blocked�
• In case using extended power wire, please
use double insulation power wire with the same
specification as the power tool.
• Avoid stopping an power tool motor when loaded�
• Never remove any chips or fragments with your
power tool's motor running�
• Never change the borer and chisel design or
use attachments and appliances, which are not
recommended for your power tool�
• When working, never press the power tool too hard,
as this might lead to the borer or chisel seizing and
motor overloading�
• Avoid the drill, borer and chisel seizing in the
material worked in� If this happens, do not try to
release them with your perforator's motor� It may
damage the motor�
• Never force out the drills, borers or chisels stuck
in the material you are working on with a hammer or
other objects the chipped off metal particles may harm
both the operator and the persons who are nearby�
