• 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
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�

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 chis-
el 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 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

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�
• 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�
Warning: the chemical substances con-
