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.

• 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 Graco 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.

ELECTRIC SHOCK HAZARD

This equipment must be grounded

.

 Improper grounding, setup, or usage of the system can cause electric 

shock.

• Turn off and disconnect power cord before servicing equipment.

• Use only grounded electrical outlets.

• Use only 3-wire extension cords.

• Ensure ground prongs are intact on power and extension cords.

• Do not expose to rain. Store indoors.
