TROUBLESHOOTING GUIDE
Possible Cause
On-Off lever in wrong position
Low pressure
No ground connection
Cascade not functioning
Failed motor function
Too conductive paint
Fluid remnants in the air passage
Wrong solvent used for final cleaning
process.
Add sufficient air pressure at handle
No pressure
Fluid tube may be plugged
Fluid nozzle may be plugged
Electrode not properly assembled
Material too viscous
No adjustment of fan pattern
Poor atomization
Fluid in air passages
Spits
Ensure the On/Off lever is in the On position.
Ensure 2.8 bar (40 psig) at the applicator
handle with applicator triggered.
Ensure the air hose is properly grounded to
the earth ground.
Ensure cascade is functioning properly, swap
parts as required.
Ensure motor is properly functioning.
Ensure paint resistance > .1 Meg Ohm
a. Clean air passage with non-polar solvent.
b. Ensure fluid nozzle is properly tightened.
Use non-polar solvent for the final cleaning
process.
Ensure 2.8 bar (40 psig) at the handle with
applicator triggered.
Ensure pressure at the fluid line at the applicator.
Replace or clean.
Replace or clean.
Reassemble tightened to stop.
Thin the material to a viscosity that is sprayable
a. Restrictor missing. Insure restrictor is
in place.
b. Fluid nozzle tightened too tight. Tighten
nozzle till it seats on the barrel o-ring then
an additional 1/8 turn
Ensure atomization air passages are clear of
all foreign particles.
Ensure fluid nozzle is properly tightened.
Ensure air before fluid is properly adjusted.
