[. . . ] Test Total Gun Resistance 312900D 23 Electrical Tests Test Power Supply Resistance 1. Remove the turbine alternator (19) from the power supply, page 32. Measure resistance from the power supply's ground strips (EE) to the conductive contact in the center of the power supply seal (FF). If outside this range, replace the power supply. If in range, proceed to the next test. Test Barrel Resistance 1. Insert a conductive rod (GG) into the gun barrel (removed for the power supply test) and against the metal contact (HH) in the front of the barrel. Measure the resistance between the conductive rod (GG) and the charging probe socket (CC). If the resistance is outside the range, replace barrel. If resistance is in range, reassemble the gun and test the gun resistance. If you still have problems, refer to Gun Repair on page 27 for other possible causes of poor performance, or contact your Graco distributor.

Do not install or repair this equipment unless you are trained and qualified. Pressurized Equipment Hazard To reduce the risk of an injury, follow the Pressure Relief procedure on page 19 whenever you are instructed to relieve the pressure. NOTE: Check all possible remedies in the Troubleshooting Chart before disassembling the gun. NOTE: Some spray pattern problems are caused by the improper balance between air and fluid. Problem Cause Solution Fluttering or spitting spray. No fluid. Loose, dirty, damaged nozzle/seat. Refill supply. Clean or replace nozzle, page 28. Air in fluid supply. Damaged nozzle or air cap. Check fluid source. Replace, page 28. Fluid buildup on air cap or nozzle. Fan air pressure too low. See Maintenance on page 20. Dirty or damaged air cap. Reduce viscosity.
