This symbol alerts you to the possibility of damage to or destruction of equipment if you do not follow the instructions. WARNING EQUIPMENT MISUSE HAZARD Equipment misuse can cause the equipment to rupture or malfunction and result in serious injury. INSTRUCTIONS D This equipment is for professional use only.
WARNING SKIN INJECTION HAZARD Spray from the gun, hose leaks, or ruptured components can inject fluid into your body and cause extremely serious injury, including the need for amputation. Fluid splashed in the eyes or on the skin can also cause serious injury. D Fluid injected into the skin might look like just a cut, but it is a serious injury. Get immediate surgical treatment. D Do not point the gun at anyone or at any part of the body. D Do not put your hand or fingers over the spray tip.
WARNING 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. D Ground the equipment and the object being sprayed. Refer to Grounding on page 7. D 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.
Installation/Operation CAUTION The Premier air motor is designed for intermittent duty cycle applications, such as spraying of corrosion control materials, or adhesive and sealant applications. It is not recommended for continuous duty circulating systems. Contact your Graco distributor for further application information. NOTE: Reference numbers and letters in parentheses in the text refer to the callouts in the figures and the parts drawings.
Installation/Operation Grounding 2. Air and fluid hoses: use only electrically conductive hoses. WARNING FIRE AND EXPLOSION HAZARD Before operating the pump, ground the system as explained below. Also read the section FIRE AND EXPLOSION HAZARD on page 5. 1. Pump: use a ground wire and clamp (supplied). See Fig. 1. Loosen the grounding lug locknut (W) and washer (X). Insert one end of a 1.5 mm@ (12 ga) minimum ground wire (Y) into the slot in lug (Z) and tighten the locknut securely.
Troubleshooting the Air Motor Preventive Maintenance Schedule The operating conditions of your particular system determine how often maintenance is required. Establish a preventive maintenance schedule by recording when and what kind of maintenance is needed, and then determine a regular schedule for checking your system. Air Motor Cylinder Premier motors require lubrication and continuous maintenance including the replacement of the air motor cylinder casting at least every 15,000,000 cycles of use.
