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
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 in-
sulated 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 sta-
ble� 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 con-
trol�
• 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 imme-
diately 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 dou-
ble 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 recom-
mended 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 mate-
rial 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�
• Avoid overheating your power tool, when using it for
a long time�
• During operation, especially on slippery or uneven
surfaces as well as when working near cliffs, slopes,
or at elevated conditions, it is necessary to exclude
the possibility of falling of both the operator and the
power tool (fencing structures or preventers must be
used)�
• In the course of the operations related to the de-
struction of building structures, it is necessary to per-
form the correct assessment of the impact of such
operations and to take necessary safety measures�
For example, choose the correct place for work and
consider escape routes depending on the debris fall-
ing direction�
• While performing the road work, it is necessary to
comply with the special safety rules (install the re-
quired road signs, wear appropriate clothing, etc�)�
Warning: the chemical substances con-
tained in dust generated in sanding, cut-
ting, sawing, grinding, drilling and other
construction industry activities may
result in cancer, congenital deficiency or be harm-
ful to the fertility. The ion of some chemical substanc-
es shall be:
• before any repair and replacement work to the
machine, the power plug must be pulled out firstly;
• the transparent two silicon oxide and other ma-
sonry products in the wall bricks and cement; the
chromium arsenic (CCA) in wood with chemical
treatment� The harm degree of these substances
shall depend on the frequent degree of you carrying
out these works� If you want to reduce the contact
with these chemical substances, please work in the
place with ventilation and you shall use the appli-
ances with safety certificates (such as the dust mask
designed with tiny dust filter).
