Safety guidelines during power tool op -
eration
Orbital sander machines are designed
only for dry grinding of various materi -
als; never use any liquids - it will result
in short circuit inside the power tool and
cancellation of warranty.
• Avoid stopping an electric tool motor when loaded�
• When grinding small workpieces too light for reliable
fixation, always use clamping appliances.
•
Do not work materials containing asbestos� Asbes-
tos is considered carcinogenic�
• Should power supply fail during work, immediately
turn the tool's switch "Off" in order to avoid accidental
turning of the machine on�
• Do not use damaged or used sanding sheets or
sanding sheets incompliant with the sanding plate di-
ameter - it may lead to damage of the machined sur-
face and cause the power tool to bounce (uncontrolled
bounce in an accidental direction)�
• During the work (particularly when working above
the head level) use protective eyewear and dust mask
at all times� The dust created during the work irritates
the eyes and the respiratory system mucous mem-
branes whereas the dust inhalation may pose a severe
threat to one's health�
• The dust created during the work may be hazard-
ous to one's health, inflammable or explosive, hence
one should clean the work place at relevant times
and use personal protection means� Always use dust
removal / collection appliances (special vacuum clean-
er, dust bag)�
•
When emptying the dust collection device, one
should maintain particular caution� Never dispose of
the dust in an open fire.
• When polishing some materials (paints with lead-
based pigments, wood impregnated with arsenic or
chromium compounds, etc�) carcinogenic or toxic
dusts may be produced� In such case, one should take
following precautions:
• all persons present on site should wear protective
clothes made of thick fabric and special anti-dust
masks (designed for protection against the hazard-
ous impact of a specific substance);
• the workplace should be well ventilated and dust
containers as well as dust removal devices (special
vacuum cleaners) must be used;
• cleaning of the workplace after work should be
performed by persons equipped with the aforesaid
personal protection means�
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�
