Resumen del manual
• Be careful not to add too much solvent, over thinning paint makes the coating hard to control and reduces its coverage . HRO-ST3131 Page 6 Mar 8, 2004 WARNING OPERATION Follow the “Pressure Relief Procedure” before operating. If there are leaks, shut off the pump immediately and release system pressure. Follow the “Pressure Relief Procedure” then tighten connections, start the pump again and check to be sure leaking has stopped. Always use the lowest pressure necessary to get the desired results, Higher pressures waste fluid and cause premature wear of the pump packings and spray tips. Never allow 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 is running too fast, shut off pump immediately and check the fluid supply. KEY POINTS BEFORE STARTING TO SPRAY 1 Check the hydraulic fluid level in the tank 2 Check the engine oil level. 3 Check the grounding of the system to prevent static sparking. 4 Flush the system and test for leaks. 5 Lubricate the pump with Hero piston lubricant part # 4-02-40-3PL1 in the wet cup. 6 Remove and check gun filter, if used, to see that it is clean. 7 Closed the prime / drain valve. 8 Check the level of paint in the supply container and see that the paint has been thoroughly mixed, and if necessary, thinned. 9 Keep the pump, hose and gun clean inside and outside. FLUSHING TO CLEAN SYSTEM Flush the pump, hose and gun with the solvent as Recommended by your material supplier. FLUSH THE PUMP BEFORE STARTING 1 Make sure that engine is shut off. WARNING : DO NOT INSTALL THE SPRAY TIP . 2 Connect a suction hose to the pump’s fluid inlet or put in a metal pail containing a gallon of compatible solvents. 3 Close the drain valve. 4 Hold a metal part of the spray gun firmly against the side of a grounded metal pail and hold the trigger open. 5 Turn the switch to the on position and start. 6 Very slowly turn the pressure regulator clockwise until the pump starts about 100 P.S.I. 7 Cycle the pump slowly until all air is pushed out, and fluid is flowing in a steady stream. 8 Release the spray gun trigger and engage the safety latch in the “Lock” position and carefully check all connections in the system for leaks. 9 Follow the “Pressure Relief Procedure” and then install the spray tip in the gun.

Never allow 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 is running too fast, shut off pump immediately and check the fluid supply. NOTE: The pump will stall out (stop) against the pressure without any damage to the pump. SETTING UP TO SPRAY 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 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...
