W D All solvent pails used when flushing or relieving pressure, always hold a metal part of the gun firmly to the side of a grounded metal pail, then trigger the gun. Z Y D To maintain grounding continuity when flushing or relieving pressure, always hold a metal part of the spray gun firmly to the side of a grounded metal pail, then trigger the spray gun. X Fig. 1 TI1052 Operation Pressure Relief Procedure 1. Close the bleed-type master air valve (required in your system). Hold a metal part of the gun to the side of a grounded metal pail and trigger the gun to relieve pressure. Open the fluid drain valve (required in your system), having a container ready to catch the drainage. Leave the drain valve open until you are ready to spray/dispense again. If you suspect that the spray tip/nozzle or hose is clogged or that fluid pressure is not fully relieved after following the steps above, very slowly loosen the tip guard retaining nut or hose end coupling and relieve pressure gradually. 307456 5 WARNING INJECTION HAZARD The system pressure must be manually relieved to prevent the system from starting or spraying accidentally.

Troubleshooting WARNING To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure on page 5. Relieve the Pressure before you check or service any system equipment. NOTE: Check all other possible problems and solutions before disassembling the pump. Solution Turn off and relieve air pressure to the motor. If the motor does not start, service the air piston (11) or springs (5 and 20). See Cleaning the Muffler on page 7. Problem Air motor stalls Air leaks down along the piston shaft (23) Air leaks from the piston shaft relief holes (23a) Slow operation 6 307456 Service NOTE: Repair Kit 214584 is available. For best results, use all the new parts in the kit, even if the old parts look good. Parts included in the kit are marked with a dagger, for example (6), in the text and illustrations. A decrease in performance accompanied by a slower than normal cycle rate is commonly caused by icing. It is recommended that the pump is shut down, and the ice is allowed to thaw. Reassemble the air piston (11), using new parts as needed. Apply a good grade of thread sealant to the threads of the screws (12).
