WARNING
Absolutely do not vacuum up sparks; flammable, explosive, of
combustible dust; or dust containing or mixed with explosive,
flammable, or combustible substances.
Absolutely do not vacuum up explosive, flammable, or
combustible liquids or dust wet with such liquids, or dust mixed
with or containing such liquids.
To prevent an accident or malfunction, absolutely do not vacuum
up damp dust or any moisture such as water or oil.
Damp dust could clog the filter and make recovery impossible.
Further, the product is not moisture or oil resistant, so an
unforeseen malfunction or accident could occur due to corrosion,
leaking, and dust accumulating in the internal duct.
Use in the same unit of substances that change into a hazardous
substance when mixed is prohibited.
Even if the individually handled dusts are safe, they may change
into a hazardous substance when mixed together. Caution is
especially required for substances the change when mixed, so we
ask that the customer be responsible for checking this. If the
safety of mixed dust cannot be determined, absolutely do not use
the same machine for both kinds of materials.
