Operation
Dust conditions
Observe the following conditions for the dust that is handled.
●This unit is for use with regular dust. It can be used to blow off dry fine dust with compressed air.
Absolutely do not vacuum up wet dust, liquids like water, oil or spray mist.
Also absolutely do not vacuum up dust containing explosive, flammable, or combustible substances.
●Do not vacuum up adhesive or corrosive substances.
●To prevent fires, absolutely do not vacuum up flames, explosive dust, or liquid mist containing dust
such as the following.
- Items that are on fire: Cigarette butts, matches, and other sources of fire.
- Things containing sparks: A large amount of sparks from grinding, dust that includes cinders, etc.
- Flammable substances: Gasoline, thinner, benzene, kerosene, etc. Materials adhered with or
containing oils, cleaning fluids, or flammable substances.
- Explosive substances: Explosive dust, such as aluminum, magnesium, titanium, and epoxy resin;
explosive materials and dust or explosive liquids that can make dust explode depending on the
conditions such as particle diameter and concentration; liquid mists or substances adhered with or
containing explosive substances.
- Combustible substances: Combustible dust, combustible liquid mist, or materials adhered with or
containing combustible materials, etc.
●Do not vacuum up flammable dust or dust containing flammable substances.
Caution must be taken in particular with non-combustible substances that change into combustible
substances when worked on, etc.
It is very difficult to determine if such substances are changing into combustible dust, so we ask the
customer to be responsible for making this determination. In addition, if a substance is determined to
be combustible dust, immediately stop using this unit.
●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.
Since an unexpected problem could occur in the disposal of mixed collected dust, we ask that the
customer be responsible for making this determination.
●Absolutely do not vacuum up damp dust or any moisture such as water or oil.
Collecting dust wet with a liquid or dusting containing a liquid could clog the filter and make operation
recovery impossible and, since 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.
