Crown CT18024 BMC [18/132] Safety guidelines during power tool operation

English

Notice the supply power voltage: in power connec-

tion, be sure to note whether the power supply volt-

age is the same as that labeled on the tool nameplate�

When the power supple voltage is higher than the volt-

age applicable to the tool, an accident will happens

to the user and meanwhile the tool itself will be de-

stroyed. Therefore, in case of the failure to conrm 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, re

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 conrm 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 efciency.

• 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 xed with xing device or pincer pliers, which

shall be fastness than holding the piece in hand�

• Before powered on, the switch must be conrmed

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 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, oors 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 nd 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 re

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

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 at 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

power tool and the wall or column so as to prevent

the power tool from ying off when the drill bits gets

blocked�

• In case using extended power wire, please use dou-

ble insulation power wire with the same specication

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 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 chisel seizing and motor over-

loading�

• Avoid the chisel seizing in the material worked in�

If this happens, do not try to release them with your

power tool motor� It may damage the motor�

• Never force out the 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

contained in dust generated in sanding,

cutting, sawing, grinding, drilling and

other construction industry activities may

result in cancer, congenital deciency or be

harmful to the fertility. The ion of some chemical

substances shall be:
