DISTORTED SPRAY 

Slightly unscrew the aircap retaining ring and rotate the aircap by 
one half turn. If the defect is reversed, one of the lateral air holes 
is plugged up or deformed. Clean the gun aircap with solvent and 
unclog the air holes with a compressed air. If the defect is not 
reversed, it means that the fluid nozzle is damaged.  

 

 
 

„

 

DISPLACED SPRAY 

This comes from a defect in the central fan. Clean the aircap and 
the fluid nozzle. Make sure that : 
-  the aircap is correctly centered on the nozzle, 
- the nozzle is not too big for the needle, 
-  when work is done with a large needle opening and the needle 

almost closed, the spray pattern is not even in all directions. 

 

 
 

„

 

FRAGMENTED PATTERN 

The fan air pressure is too big at the holes in the air cap horns : 
-  turn the fan air control clockwise to reduce the fan air pressure. 
-  increase the paint output.  

 

 

 
 

„

 

FAN TOO THICK IN THE CENTER 

This is the reverse of the above defect : 
- the paint output is too high for the selected air pressure : 

increase the spraying air pressure and reduce the paint output. 

-  if the paint is too thick, dilute it. 

 

„

 

INTERMITTANT SPRAY PATTERN 

An air inlet in the paint circuit creates an intermittant pattern when : 

- the paint cup is nearly empty, 
- when the nozzle is not tightened on its seat : clamp it. 
If the problem persists, remove the nozzle and clean it. Check that the seat and the cone are not 
damaged, remount the nozzle and clamp it. 

When using a cup, air can get into the paint circuit :  
through the passage seal of the needle into the gun body 

 tighten it. 

through various fittings between the gun and the cup if these are not correctly tightened. 

Check that : the cup cover air hole is not blocked and the paint is homogeneous and fluid enough (use 
the viscosity cup).
