COMPLIANCE WITH PROTECTIVE MEASURES AND DANGER SIGNALS
Danger: Do not use the machine unless it is properly assembled; not doing so could cause personal injury
and/or damage to property. Ensure that all locking parts are firmly in place. Ensure that machine is set up in
accordance with the specifications.
Danger: Any use of the sander without guards and housings fitted and locked in place could cause personal
injury and/or damage to property. Always ensure that all guards and housings are in place and properly
secure.
Danger: Sanding wood floors can create an explosive environment. Cigarettes, cigars, pipes, lighters, pilot
lights and any other source of fire could cause an explosion, if lit during sanding work. Sources of ignition
should be kept well away from the work area.
Danger: Poorly ventilated work areas could cause an explosive environment if there are combustible
materials in the atmosphere, such as solvents, thinners, alcohol, fuels, some paints, wood dust or any other
combustible material. Floor sanders can cause combustible materials and vapours to ignite. Read the
manufacturer's instructions for any chemicals used, in order to determine whether or not they are
combustible. Ensure that the work area is always well ventilated.
Danger: Nails encountered during sanding can cause sparks. Always remove all nails before sanding
surfaces.
Danger: If the breaker on the power circuit trips several times or if it is under-rated, there is a risk of death
from electrocution. Have fuses, the protection circuit or the mains checked by a qualified electrician or by
Romus after-sales.
Danger: Any maintenance and/or repairs made to a machine that is not properly disconnected from the
mains could cause death by electrocution. Disconnect from the mains before carrying out any maintenance
and/or repair operation.
Danger: Use of this machine on an unearthed circuit cold cause death by electrocution. Never disconnect or
render the earth cable ineffective. If there is no earth wire or if you have doubts about the correct earthing
