Refer to the separate lubricator instruction manual. Release the spray valve trigger and let the pump run. NOTE: Protect surfaces that might be damaged by the cleaning solution and rinse off before the solution dries. For removing stubborn dirt, use a strong, heated solution. Useful Hints WARNING To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure on page 8. Hold the spray nozzle about 2 feet (0.6 m) from the surface you are cleaning and mist-wet it completely. Let it soak briefly, then use the spray to “chisel” the dirt off. Keep the nozzle at an angle, about 6 in. (150 mm) from the surface. If some dirt remains, wet the surface again. Let the object soak a little longer, then hold the nozzle as close as possible and spray to blast the dirt off. After the dirt is removed, through rinse off the remaining solution with clear, cold water. When you are done cleaning, close the pump air bleed valve and relieve the pressure. Shutdown and Care of Unit CAUTION To reduce the risk of damaging your pump. never allow the pump to run dry of fluid. Keep liquid in the container to prevent the pump from running away. WARNING To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure on page 8. When shutting down for the day or weekend, shut off both the bleed–type air valve and pump air bleed valve. Relieve the pressure. Rinse off any solution remaining on equipment with clear, cold water. Shut off the water supply valve and relieve the water pressure. After shutdown, check the air line lubricator (G) often and keep it filled with oil. Also check the pump packing nut regularly and keep it just tight enough to stop leakage, but no tighter. Use a 1/4 in. diameter rod to tighten. . . Troubleshooting WARNING To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure on page 8. Before servicing this equipment always make sure to relieve the pressure. Note: Check all possible problems and solutions before disassembling.

Service General WARNING To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure on page 8. See Parts illustration for referenced items. Shut off the air supply to the pump and relieve the pressure. Check the air line lubricator often and keep it filled with oil. Also check the pump packing nut regularly to keep it just tight enough to stop leakage, but no tighter. Use a 1/4 in. (6.3 mm) diameter rod to tighten. To manually lubricate the motor, disconnect the air line at the motor and place 10 to 15 drops of oil in the inlet. Reconnect the air line and turn on the air to blow oil into the motor. Shut off the air supply to the pump and relieve the pressure. Proper packing nut take-up will stop leakage. However, all the packings should be replaced after 1000 hours of operation or delivery of 120,000 gallons of solution at 2 gpm. Refer to separate pump manual. Clean the air line filter regularly. Remove the inlet filter (2) daily and clean it. Check it for damage that may allow contaminants to en...
