WARNING
FIRE AND EXPLOSION HAZARD
Flammable fumes, such as solvent and paint fumes, in work area can ignite or explode. To help prevent
fire and explosion:
• Do not spray flammable or combustible materials near an open flame or sources of ignition such as
cigarettes, motors, and electrical equipment. Only use water-based or mineral spirit-type materials
with a flash point greater than 70° F (21° C).
• Paint or solvent flowing through the equipment is able to result in static electricity. Static electricity
creates a risk of fire or explosion in the presence of paint or solvent fumes. All parts of the spray system, including the pump, hose assembly, spray gun, and objects in and around the spray area shall
be properly grounded to protect against static discharge and sparks. Use conductive or grounded
high-pressure airless paint sprayer hoses.
• Verify that all containers and collection systems are grounded to prevent static discharge.
• Connect to a grounded outlet and use grounded extensions cords. Do not use a 3-to-2 adapter.
• Do not use a paint or a solvent containing halogenated hydrocarbons.
• Keep spray area well-ventilated. Keep a good supply of fresh air moving through the area. Keep
pump assembly in a well ventilated area. Do not spray pump assembly.
• Do not smoke in the spray area.
• Do not operate light switches, engines, or similar spark producing products in the spray area.
• Keep area clean and free of paint or solvent containers, rags, and other flammable materials.
• Know the contents of the paints and solvents being sprayed. Read all Material Safety Data Sheets
(MSDS) and container labels provided with the paints and solvents. Follow the paint and solvents
manufacturer’s safety instructions.
• Fire extinguisher equipment shall be present and working.
• Sprayer generates sparks. When flammable liquid is used in or near the sprayer or for flushing or
cleaning, keep sprayer at least 20 feet (6 m) away from explosive vapors.
SKIN INJECTION HAZARD
• Do not aim the gun at, or spray any person or animal.
• Keep hands and other body parts away from the discharge. For example, do not try to stop leaks with
any part of the body.
• Always use the nozzle tip guard. Do not spray without nozzle tip guard in place.
• Use nozzle tips.
• Use caution when cleaning and changing nozzle tips. In the case where the nozzle tip clogs while
spraying, follow the Pressure Relief Procedure for turning off the unit and relieving the pressure
before removing the nozzle tip to clean.
• Do not leave the unit energized or under pressure while unattended. When the unit is not in use, turn
off the unit and follow the Pressure Relief Procedure for turning off the unit.
