Do not use 1,1,1-trichloroethane, methylene chloride, other halogenated hydrocarbon solvents, or
fluids containing such solvents in the turbine spray system, which contains aluminum and/or
galvanized-coated parts. Such use could result in a serious chemical reaction, with the possibility
of explosion, which could cause death, serious injury, and/or substantial property damage.
FIRE AND EXPLOSION HAZARD
Improper grounding, poor ventilation, open flames or sparks can cause a hazardous condition and
result in a fire or explosion and serious injury.
Use fluids compatible with the equipment wetted parts. Refer to the Technical Data section of all
equipment manuals. Read the fluid and solvent manufacturer’s warnings.
Ground all equipment, containers, and objects being sprayed. Page 6.
If there is any static sparking or you feel an electric shock while using this equipment, stop
spraying immediately. Do not use the equipment until you identify and correct the problem.
Use only in extremely well ventilated areas. Provide fresh air ventilation to avoid the buildup of
flammable fumes from solvents or the fluid being sprayed.
Keep the work area free of debris, including solvent, rags, and gasoline.
Locate the sprayer at least 20 ft (6.1 m) away from any explosive vapors, due to arcing parts.
Comply with all applicable local, state, and national fire, electrical, and safety regulations.
Avoid all ignition sources.
– Extinguish all open flames or pilot lights in the spray area.
– Do not smoke in the spray area.
– Do not turn any light switch in the spray area on or off while operating equipment or if fumes are
present.
– Do not operate a gasoline engine in the spray area.
Pressure can cause a rusted tank to explode. Drain tank after each use by opening air tank drain
valve located under the sprayer.
CLEANING SOLVENT HAZARD WITH PLASTIC PARTS
Use only compatible solvents to clean plastic structural or pressure-containing parts. Many solvents
can degrade plastic parts to the point where they could fail. Such failure could cause serious injury or
property damage. See the Technical Data section on page 15 in this instruction manual and in all
other equipment manuals. Read the fluid and solvent manufacturer’s warnings.
