9.  TROUBLESHOOTING

A faulty spray is usually caused by improper cleaning or dried material around the fluid nozzle tip or in the air cup - use a brush and solvent to 

remove.  Never use metal instruments to clean the air cup or paint nozzle.  These parts are carefully machined and any damage to them will cause 

a faulty spray.  If either the air cup or paint nozzle is damaged, the part must be replaced before a perfect spay can be obtained.

Dried material in a dirty side port restricts 

passage of air. Greater flow of air from the 

cleaner side port forces the fan pattern in the 

direction of the clogged side.

Dried material around the outside of the fluid 

nozzle tip restricts the passage of atomizing air at 

one point through the centre opening of the air 

cup and results in the pattern shown.  

This pattern can also be caused by a loose air 

cup.

A split spray or one that is heavy at each end of 

the fan pattern and weak in the middle is usually 

caused by too high an atomization air pressure or 

by attempting to get too wide a spray with thin 

paint.

1.  Worn needle packing permits air to get  

    into the fluid passageway. This results in    

     spitting.

2.  Dirt between the paint nozzle seat and body  

  or a loose paint nozzle will cause the gun to  

 spit.

3.  A loose or defective joint between the pot  

  and gun can cause spitting.

Dissolve material in the side ports with solvent, then 

blow the gun clean.  

DO NOT

 poke the orifice with a metal instrument.

Remove the air cup and wipe off fluid tip using a rag 

dampened with solvent.  

Tighten the air cup.

Check supply pressure and reduce if over 50psi. 

Adjust the air atomisation valve to reduce pressure and 

adjust paint needle if required. 

Check spray pattern on a test panel.

1.  Tighten the packing screw or, in severe cases,   

  replace the packing.

2.  Remove the fluid nozzle, clean the back of the   

  nozzle and the nozzle seat in the gun body using a  

  rag dampened with solvent. 

3.  Tighten or replace.
