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 con-
trolled with the switch is dangerous and must be re-
paired�
• Disconnect the plug from the power source and /
or the battery pack from the power tool before mak-
ing any adjustments, changing accessories, or
storing power tools� Such preventive safety meas-
ures reduce the risk of starting the power tool acciden-
tally�
• 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 guidelines during
power tool operation
• When the cutting operation is in process, please
wait for the motor entering into the normal
operation, then the work shall be continued. If the
motor is operated before entering into the normal
operation, the cut surface of the workpiece shall be
uneven�
• The overlarge load shall not be applied to the
products. The incorrect operating ways shall result in
the breakage of the grinding wheel, and the motor shall
be damaged�
• The surface bounce of the grinding wheel shall
be confirmed. If the bounce of the new grinding wheel
is overlarge, then the grinding wheel shall be broken�
If surface runout of grinding wheel is too large, please
replace it with a new one�
• The eyes protector shall be worn.
• The broken grinding wheel shall not be used.
• The proximate matter without shield at the right
position shall not be used.
• The grinding wheel recommended by the
manufacture shall only be used, and the indicated
speed shall equal or exceeds the indicated speed
of the tools� The grinding wheel with linear speed no
less than 4800 min
• The operating instructions provided by the
grinding wheel manufacture shall be read care-
fully.
• Do not impact the grinding wheel. If the grinding
wheel under rotation is impacted, then the grinding
wheel shall be broken, and the serious injury shall be
caused to the human body�
• Do not use the surface of the grinding wheel to
grind the work. If the surface of the grinding wheel is
used to grind the work, then the grinding wheel shall
be broken, and the serious injury shall be caused to
the human body�
• Unconcerned personnel shall not be allowed
to get close. During the operation, the spark
produced shall make injury to the human body.
• When the parts (clips, gaskets, screws, etc.)
have any breakage, please stop using them. When
it is not fixed and stable while using, the grinding wheel
shall be broken, and the injury to the human body shall
be caused�
• The direction of the spark produced in the
cutting shall against to the place which is not
dangerous. If any inflammable matters exist around
the spark, the safety accidents may be caused�
• The operation shall be executed after the
workpiece is reliably clamped to the working
chassis. No fixed clamped workpiece shall be burst
out to cause the injury to the human body�
Before commencing operation
• Use this power tool only for dry cutting�
• Use the power tool only for cutting material
recommended by the manufacturer�
• Before use, place the power tool on a steady
horizontal base�
• Do not use cutting discs with dimensions (outside
and mounting diameter) different from recommended�
• Never use other types of cutting disc (circular saw
blades, diamond cutting blades etc�) for this power
tool�
• Ensure that all devices preventing accidental
touching of the cutting disc are properly mounted,
functional and in perfect order�
• Never work with protection devices dismounted�
Damaged protection devices must be replaced
immediately�
• During operation never fix (bind, wedge, etc.) the
sliding guard covers open�
• Never cut wooden workpieces or pieces made of
other materials that are not mentioned herein� The
cutting disc is designed for cutting metal only� If the disc
is used for wood (or other materials), it may change its
shape due to overheating� Such deformation may lead
to serious injury of an operator or other persons in the
immediate vicinity of the power tool�
