Warnings
The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclama-
tion point symbol alerts you to a general warning and the hazard symbols refer to procedure-specific risks. When
these symbols appear in the body of this manual or on warning labels, refer back to these Warnings. Product-specific
hazard symbols and warnings not covered in this section may appear throughout the body of this manual where
applicable.
FIRE AND EXPLOSION HAZARD
Flammable fumes, such as solvent and paint fumes, in work area can ignite or explode. Paint or solvent
flowing through the equipment can cause static sparking. To help prevent fire, explosion, and electric
shock:
• Ground all equipment in the work area. See Grounding instructions.
• Only use grounded Graco conductive air supply hoses.
• Do not use pail liners unless they are conductive and grounded.
•Stop operation immediately if static sparking occurs or you feel a shock.Do not use equipment
until you identify and correct the problem.
• Use and clean equipment only in well ventilated area.
• Control flush pressures to less than 300 psi (2 MPa, 21 bar) to reduce material flow velocity and
reduce the static buildup that can occur with certain material chemistries.
• Eliminate all ignition sources; such as pilot lights, cigarettes, portable electric lamps, and plastic drop
cloths (potential static sparking).
• Do not plug or unplug power cords or turn lights on or off when flammable fumes are present.
• Keep work area free of debris, including solvent, rags and gasoline.
• Keep a working fire extinguisher in the work area.
Electrostatic Gun Precautions
• Electrostatic equipment must be used only by trained, qualified personnel who understand the
requirements of this manual.
• Check gun resistance, hose resistance, and electrical grounding daily.
• Always turn the electrostatics off when flushing, cleaning or servicing equipment.
• Do not flush the system with the gun electrostatics turned on.
• Interlock the gun turbine air supply to prevent operation of the power supply during flushing.
• Do not turn on the gun electrostatics until all solvent is purged from the system.
• Use cleaning solvents with highest possible flash point when flushing or cleaning equipment.
• Never spray or flush solvent at high pressure.
• To clean the exterior of the equipment, cleaning solvents must have a flash point at least 15°C
above ambient temperature. Non-ignitable fluids are preferred.
