an undamaged disc. After inspecting and install-
ing the disc, position yourself and bystanders
away from the plane of the rotating disc and run
the power tool at maximum no load speed for one
minute. Damaged disc will normally break apart dur-
ing this test time�
• Wear personal protective equipment. Depend-
ing on application, use face shield, safety goggles
safety glasses. As appropriate, wear dust mask,
hearing protectors, gloves and shop apron capable
of stopping small abrasive or workpiece fragments.
The eye protection must be capable of stopping flying
debris generated by various operations� The dust mask
or respirator must be capable of filtrating particles gen-
erated by your operation� Prolonged exposure to high
intensity noise may cause hearing loss�
• Keep bystanders a safe distance away from
work area. Anyone entering the work area must
wear personal protective equipment. Fragments of
workpiece or of a broken disc may fly away and cause
injury beyond immediate area of operation�
• Hold the power tool by insulated gripping surfac-
es only, when performing an operation where the
diamond cutting disc may contact hidden wiring or
its own cord. Diamond cutting disc contacting a "live"
wire may make exposed metal parts of the power tool
"live" and could give the operator electric shock�
• Position the cord clear of the spinning diamond
cutting disc. If you lose control, the cord may be cut
or snagged and your hand or arm may be pulled into
the spinning disc�
• Never lay the power tool down until the diamond
cutting disc has come to a complete stop. The spin-
ning disc may grab the surface and pull the power tool
out of your control�
• Do not run the power tool while carrying it at
your side. Accidental contact with the spinning dia-
mond cutting disc could snag your clothing, pulling the
disc into your body�
• Regularly clean the power tool's air vents. The
motor's fan will draw the dust inside housing and ex-
cessive accumulation of powdered metal may cause
electrical hazards�
• Do not operate the power tool near flammable
materials. Sparks could ignite these materials�
• Always process only one blank - this is the only way
to fix it properly.
• Avoid stopping the power tool motor when under load�
• Avoid overheating your power tool, when using it for
a long time�
• Never operate the power tool over your head level�
• Never try to slow down the inertial rotation of the
diamond cutting disc by applying effort to the cutting
disc lateral surface�
• The diamond cutting disc can get very hot during
operation - do not touch them until they have cooled
down�
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 harmful to
the fertility. The ion of some chemical substances
shall be:
• Before any repair and replacement work to the ma-
chine, 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 treat-
ment� 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 appliances with
safety certificates (such as the dust mask designed
with tiny dust filter).
Notice the power voltage: in power connection, you
must confirm that if the power voltage is the same to
the voltage marked in the tool's data plate� If the power
voltage is higher than the appropriate voltage, the acci-
dents will be resulted to the operators, and at the same
time, the tool will be destroyed� Therefore, if the power
voltage has not been confirmed, then you shall never
plug in arbitrarily� On the contrary, when the power
voltage is lower than the required voltage, the motor
will be damaged�
