[. . . ] If the pump fails to prime properly, open the bleeder valve plug (AB) slightly. Use the bleed hole as a priming valve until the fluid appears at the hole. Stop the pump at the bottom of its stroke to prevent fluid from drying on the exposed displacement rod and damaging the throat packings. When changing fluid containers with the hose and gun already primed, open the bleeder valve plug (AB), to assist in priming the pump and venting air before it enters the hose. With the pump and lines primed, and with adequate air or hydraulic pressure and volume supplied, the pump will start and stop as the gun is opened and closed. In a circulating system, the pump will speed up or slow down on demand, until the air or hydraulic supply is shut off. Always use the lowest air or hydraulic pressure necessary to get the desired results. For air-powered pumps, use the air regulator (F) to control the pump speed and fluid pressure. For hydraulic-powered pumps, use the fluid pressure gauge (F) and flow control valve (G) to control the pump speed and the fluid pressure. 1 Bleed hole must face down. AC AA 1 AB 9. A dry pump will quickly accelerate to a high speed, possibly damaging itself. TI8364a FIG. Bleeder Valve and Wet-Cup 14 311826C Maintenance Maintenance 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. Follow Pressure Relief Procedure, page 13, and remove fluid filter and soak in solvent. Keep the wet-cup 1/3 filled with Graco Throat Seal Liquid (TSL) or compatible solvent. Using the supplied wrench (108), adjust the packing nut weekly so it is just snug; do not overtighten. Torque to 135-169 N·m (100-125 ft-lb). Corrosion Protection Always flush the pump before the fluid dries on the displacement rod. First, flush with water or a compatible solvent, then with mineral spirits. Relieve the pressure, but leave the mineral spirits in the pump to protect the parts from corrosion. Flushing Hydraulic Systems CAUTION Keep the hydraulic supply system absolutely clean at all times. Blow out hydraulic lines with air and flush thoroughly with solvent before connecting to the hydraulic motor, to avoid introducing harmful contaminants into the motor. Carefully follow the manufacturer's recommendations on reservoir and filter cleaning, and periodic changes of hydraulic fluid. Do not substitute a lower grade oil or one with a lower flash point. · Flush before changing colors, before fluid can dry in the equipment, at the end of the day, before storing, and before repairing equipment. Flush with a fluid that is compatible with the fluid being dispensed and the equipment wetted parts. · · 1. Place siphon tube in grounded metal pail containing cleaning fluid. 311826C 15 Troubleshooting Troubleshooting 1.
