HAZARD
Poorly ventilated work areas may create an explosive environment when some
combustible materials are present in the atmosphere, such as solvents, thinners,
alcohol, fuel, some paints, wood dust or other combustible materials. Floor sanding
machines may cause various materials and fumes to ignite. Read the manufacturer's
instructions for each chemical product used and establish its combustibility. Always
keep the work area well-ventilated.
HAZARD
Striking nails when sanding may generate an explosion or fire. Always ensure all nails
are sunk before sanding surfaces.
HAZARD
Serious damage may occur if the power supply circuit trips repeatedly or is undersized.
Have the fuses, safety circuit and power supply line checked by an authorised
electrician.
HAZARD
Performing maintenance and/or repairing the machine when it is not fully disconnected
from the power supply may cause death due to electrocution. Disconnect the power
supply before carrying out any maintenance and/or repair work.
HAZARD
The use of this machine on a circuit which is not earthed may cause death due to
electrocution. Never disconnect or disable the earthing conductor. Consult an
electrician if the earth conductor is missing or it is suspected that the circuit is not
suitably earthed.
