. Make sure drain valve is open. • Start the engine. • Open the hydraulic ball valve to allow hydraulic fluid to flow to hydraulic motor. • Paint pump should start to pump material and you should notice material flowing out to prime valve. • Let the pump run until the material is flowing evenly out of prime valve. • Close the prime valve and unit should now build up with pressure. • Run the pump until paint flows smoothly from the gun, without spitting, release the trigger. • Adjust the pump to the minimum pressure required to obtain the desired spray pattern of paint. If atomization is not possible on thick paints, thin with the compatible solvent. • Use the lowest pressure setting possible. • If the pump accelerates quickly or is running too fast, stop the pump immediately and check the material supply. • Don’t leave a pump shut off for a long period of time, if the material supply has been exhausted and air has been pumped into the lines. This can cause the material possibly to dry in the lines. • Prime the pump and lines with material or flush and leave filled with solvent, with the pressure relieved. MAINTENANCE DAILY SHUTDOWN PROCEDURE” • Close the on-off air valve to the pump. • Always be sure to stop the pump at the bottom of the stroke to prevent paint from drying on the displacement rod and damaging the throat packings. • Always bleed off the paint pressure in the system by triggering the gun and opening the drain valve, making sure to have a container ready to catch the paint draining from the drain valve. • Remove the tip from the gun and clean and leave it in solvent until ready to use again. • Do not disconnect the gun or hoses, keep the unit filled with solvent to reduce the need for flushing. NOTE: .When using fast drying paints, immerse the suction tube in a container of solvent during shutdown. .Clean the pump’s intake screen. SHUTDOWN FOR STORAGE Always follow the “Pressure Clearance Procedure” and when storing the unit proceed as follows: • Flush the unit clean, as instructed . It may take repeated flushing with solvent or water, to clean the system thoroughly. • Fill the pump, hoses, and gun full of solvent. If the flushing solvent used as water or a keytone type solvent, fill the system with mineral spirits or light oil for storage over a long period. Wipe all external wetted parts of the pump with oil. Make sure that water or keytone solvent is removed from the wet cup/ packing nut. - Page 8 Mar 8, 2004 TROUBLE SHOOTING TROUBLE POSSIBLE CAUSE REMEDY Pump will not stroke. 1. Ball valve on the hydraulic shut off valve not opened to the on position. 2. Low or no hydraulic fluid 3. Pressure regulator not turned up to high enough pressure. 4. Poor or damaged hydraulic pump 5. Damaged hydraulic motor 6. Paint pump at full pressure. 7. Paint pump seized. 1. Turn ball valve to the on position. 2. Fill with correct fluid. 3. Slowly increase the pressure by turning the regulator knob clockwise. 4. Call technical service department. 5. Call technical service department. 6. Follow “pressure relief instructions” 7. Follow pressure relief procedures and check the following; hardened paint in pump. Pump stokes, but poor performance. 1. Fault in pump section. 2. Worn spray tip. 3. Improper tip size. 4. Material too viscous ( thick ). 5. Gun filter and / or pump filter plugged. 6. Engine may not be running correctly. 7. Fluid section seized by dry paint. 1. Pump may need repair. 2. Replace tip. 3. Replace tip. 4. Thin material with appropriate thinners, per product manufacturer’s instructions. 5. Clean or replace filter(s). 6. Check and choke and throttle positions. 7. Clean & rebuild fluid section. See 15-17 Low or Erratic Output / Pressure 1. Air leaks or blockages. 2. Worn Upper Packings, Intake or Outgo balls and / or seats. 3. Cylinder sleeve leakage. 4. Worn spray tip. . 1. Check the following; . Intake tube fitting. . Plugged intake screen. . Intake Teflon O-ring. 2. Re-pack pump. 3. Replace cylinder sleeve seal ( ref# 15). 4. Change tip. HRO-ST3131 Page 9 Mar 8, 2004 WARNING If there are leaks, shut off the pump immediately and release system pressure follow the “Pressure Clearance Procedure” then tighten connections, start the pump again and check to be sure leaking has stopped. Always use the lowest air pressure necessary to get the desired results, higher pressure waste fluid and cause premature wear of the pump packing and spray tip. Never operate the pump to run dry of the fluid being pumped because a dry pump will quickly accelerate to a high speed, possibly damage itself. If the pump accelerates quickly or running too fast, shut off immediately and check the fluid supply. NOTE: The pump will stall out (stop) against pressure without damage to the pump. SPRAY STARTING AND ADJUSTING Always follow the “Pressure Relief Procedure” before cleaning, , or, removing the equipment or servicing any part of system equipment. • Immerse the pump intake or suction tube in paint. • Make sure drain valv...
