DWT AWS-20-115 D Notice Originale page 25

• Do not use worn down wheels from larger power
tools. Wheel intended for larger power tool is not suit-
able for the higher speed of a smaller tool and may
burst�
• When using cymbal-shaped grinding wheel, you
should ensure glass fiber reinforced plastic grind-
ing wheel is used only.
• Principal axis, flange (especially the mounting
surface) or lock nut shall not be damaged to avoid
fracture of grinding wheel.
• Before the switch is turned on, you should en-
sure the grinding wheel is not in touch with the
workpiece.
• Before the tool comes into use, you should let
the tool run for a while. Please note that vibration
or swing may indicate poor installation or imbal-
ance of the grinding wheel.
• Grinding shall be carried out on designated sur-
face of the grinding wheel.
• Attention should be paid to the flying sparks.
When holding the tool, you should avoid sparks' flying
to you or other people or combustible�
• The tool shall not be left alone during operation.
You should operate the tool only when you hold it�
• You shall not touch the workpiece immediately
after operation considering that it might be very
hot and cause skin burns.
• Before the tool is used for any operation, you
should switch off the tool, pull out the power plug
or take out the battery box.
• Please follow instructions of the manufacturer
for proper installation and use of the grinding
wheel. Please be careful to handle and store the grind-
ing wheel�
• Do not use separate release casings or adapters
to fit the large hole grinding wheel.
• Please use the flange specified for the tool.
• With respect to the tool used for installing
threaded hole grinding wheel, please ensure
thread in the grinding wheel is long enough and
could match the length of principal axis.
• Check and ensure that the workpiece is properly
supported.
• Please note that, after cutting off power supply
of the tool, the grinding wheel will continue to ro-
tate.
• Please use short circuit breaker (30mA) to en-
sure safety of the operator when it is very hot and
moist in the workplace or you are seriously pol-
luted by conductive dust.
• Do not use the tool on any material containing
asbestos.
• Do not use water or grinding fluid.
• Please ensure that the ventilation opening is
clean when working in dusty environment. If the
dirt must be removed, please cut off the power of the
tool (with non-metal article) to avoid damage to internal
parts�
Additional safety instructions for cutting-off op-
erations
• Do not position your body in line with and be-
hind the rotating wheel. When the wheel, at the point
of operation, is moving away from your body, the pos-
sible kickback may propel the spinning wheel and the
power tool directly at you�
• When wheel is binding or when interrupting a cut
for any reason, switch off the power tool and hold
the power tool motionless until the wheel comes
to a complete stop. Never attempt to remove the
cut-off wheel from the cut while the wheel is in mo-
tion otherwise kickback may occur. Investigate and
take corrective action to eliminate the cause of wheel
binding�
• If the power supply suddenly cuts during operation,
immediately move on / off switch into off in order to
prevent accidental starting of the power tool�
• Slow the rotation of the accessories caused by iner-
tia down with the help of spindle lock or applying force
to the side surface of discs is strictly forbidden� Using
spindle lock for this purpose will put the power tool out
of operation and void the warranty�
Warning: the chemical substances con-
tained in dust generated in sanding,
cutting, 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 sub-
stances 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 masonry
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 sub-
stances, 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�
Following symbols are used in the operation manual,
