See FIG. 2. � If the fluid control valve is turned clock- wise all the way, the gun will emit only air. � If you cannot achieve the correct fluid flow with the fluid control valve, a differ- ent sized nozzle may be necessary. For smaller fluid flow, use the next size smaller nozzle. For a larger fluid flow, use the next size larger nozzle. ti

Operation Operation See Troubleshooting, page 12, if you experience an irregular pattern. Pressure Relief Procedure When using the HVLP spray gun, instead of a conventional airspray gun, you may need to use a slightly slower hand movement and make fewer passes with the gun to coat a part. Trapped air can cause the pump to cycle This is due to the reduced spray velocity pro- unexpectedly, which could result in serious duced by lower HVLP air pressures, along with injury from splashing or mo
