TroubleshootingSpray Pattern TroubleshootingWARNINGPRESSURIZED EQUIPMENT HAZARDTo reduce the risk of a serious injury, follow the PressureRelief Procedure on page 13 before checkingor repairing any part of the gun or system.PROBLEM CAUSE SOLUTIONFluid flow is fluttering while spraying Fluid nozzle not tight enough Tighten fluid nozzle to 125–135 in-lb(14–15 Nm).Fluid flow fades while spraying highviscosity fluidsPattern becomes off-set or heavy onendsGun fluid pressure is too high withgun triggeredUsing a low fluid pressure setting,the fluid flow is too high, making itnecessary to restrict needle travel toreduce fluid flowFluid system will not operate at lowenough fluid pressure [below 10 psi(70 kPa, 0.7 bar)]Fluid filter cloggedAir hose size is too restricted forhigher air flow being usedFluid pressure too low, causing fluidflow to reduce when gun is elevatedAir cap horn holes plugged or damagedUsing needle/nozzle kit with toosmall orificeUsing needle/nozzle kit with toolarge orificeThere is no fluid regulator, or airregulator on pressure pot is not sensitiveenough at low pressuresCheck fluid filter.Use 5/16 in. (7.9 mm) I.D. air hose ifthe hose is 25 ft. (7.625 m) long. Iflonger hose is needed, use a 3/8 in.(9.5 mm) I.D. hose.Raise fluid pressure at source or usea smaller fluid nozzle.Clean air cap horn holes with nonmetallicitem such as a toothpick, orreplace air cap.Use needle/nozzle kit with largerorificeUse needle/nozzle kit with smallerorificeAdd low pressure fluid regulator, oradd more sensitive low pressure airregulator on pressure pot.309029 19
