Important Safety •Read all safety inform n before
opera the equipment. Save these
To reduce the risks of fire or explosion, electrical shock and the injury to persons, read and understand all inst included in this manual. Be
familiar with the controls and proper usage of the equipment.
Indicates a hazardous situa on which, if not avoided,
could result in death or serious injury.
HAZARD: EXPLOSION OR FIRE
Solvent and paint fumes can explode or ignite.
Severe injury or property damage can occur.
PREVENTION:
•Provide extensive exhaust and fresh air introduc n to keep the air
within the spray area free from n of
flammable vapors.
•Avoid all igni on sources such as sta c electric
sparks, open flames, pilot lights, electrical
appliances, and hot objects. Con or
power cords or working light
switches can make sparks.
•Do not smoke in spray area.
•Fire sher must be present and in good working order.
•Use only outdoors in a well-ve ed area. Flammable vapors are
heavier than air. The turbine contains arcing parts that emit sparks and can
ignite vapors.
•Follow the material and solvent manufacturer’s warnings and
•Do not use materials with a flashpoint below 70°F
(21°C). Flashpoint is the temperature that a fluid can produce enough
vapors to ignite (see coa g supplier).
•Plas c can cause sta c sparks. Never hang plas c to enclose the spray
area. Do not use drop cloths when spraying flammable materials.
HAZARD: EXPLOSION HAZARD DUE TO
INCOMPATIBLE MATERIALS.
Will cause property damage or severe injury.
PREVENTION:
•Do not use materials containing bleach or
chlorine.
•Do not use halogenated hydrocarbon solvents such as bleach,
mildewcide, methylene chloride and 1,1,1--trichloroethane. They are not
compa e with aluminum.
•Contact your coa g supplier about the compa lity of
material with aluminum.
HAZARD: HAZARDOUS VAPORS
Paints, solvents, insec cides, and other
materials can be harmful if inhaled or come in
contact with the body. Vapors can cause
severe nausea, fa g, or poisoning.
PREVENTION:
•Use a respirator or mask if vapors can be
inhaled. Read all instruc ons supplied with
the mask to be sure it will provide the
necessary prote .
•Wear eyewear.
•Wear clothing as required by coa g manufacturer.
HAZARD: GENERAL
Can cause severe injury or property damage.
PREVENTION:
•Read all instruc ons and safety before
equipment.
•Follow all appropriate local, state, and codes
governing ven a , fire preven on, and
•Use only manufacturer authorized parts. User assumes all
risks and liabili es when using parts that do not meet the
minimum specifica s and safety devices of the turbine
manufacturer.
•Do not spray outdoors on windy days.
