WARNING
MOVING PARTS HAZARD
Moving parts can pinch, cut or amputate fingers and other body parts.
• Keep clear of moving parts.
• Do not operate equipment with protective guards or covers removed.
• Pressurized equipment can start without warning. Before checking, moving, or servicing equipment, follow the
Pressure Relief Procedure and disconnect all power sources.
EQUIPMENT MISUSE HAZARD
Misuse can cause death or serious injury.
• Always wear appropriate gloves, eye protection, and a respirator or mask when dispensing.
• Do not operate or dispense near children. Keep children away from equipment at all times.
• Do not overreach or stand on an unstable support. Keep effective footing and balance at all times.
• Stay alert and watch what you are doing.
• 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.
• Do not operate the unit when fatigued or under the influence of drugs or alcohol.
• Do not kink or over-bend the hose.
• Do not expose the hose to temperatures or to pressures in excess of those specified by Graco.
• Do not use the hose as a strength member to pull or lift the equipment.
PRESSURIZED ALUMINUM PARTS HAZARD
Use of fluids that are incompatible with aluminum in pressurized equipment can cause serious chemical reaction and
equipment rupture. Failure to follow this warning can result in death, serious injury, or property damage.
• Do not use 1,1,1-trichloroethane, methylene chloride, other halogenated hydrocarbon solvents or fluids containing such
solvents.
• Many other fluids may contain chemicals that can react with aluminum. Contact your material supplier for compatibility.
