TROUBLESHOOTING GUIDE
Note: A test station to bench test the applicator off-line will speed the Troubleshooting process.
General Problem
Possible Causes
Corrective Action
Fluid Does Not
Turn On
No Fan or Atomi-
zation Air Pressure
At the Air Cap
Excessive Current
or Loss of High
Voltage
1. Trigger pilot regulator has
not been set to a minimum
of 70 psig
2. The green air tube possibly
left disconnected during re-
assembly
3. Green tube leading from
the source to the applicator
mounting plate is pinched or
broken
4. Piston seal within the appli-
cator spray head is not in
place or there is an ex-
tremely tight fit between the
seal and the cylinder wall
5. PT is not actuated
6. Paint trigger (BA/PT) not
actuated
1. Low trigger pilot air pres-
sure (70 psi min. required)
2. Air tubes 79134-00 are not
installed properly.
3. Blue or gray 3/8" OD
tube is cut or pinched
1. Metallic particle alignment
in coiled tube
2. Fluid leaks inside
3. Fluid coil pin-holed
4. Exterior of applicator
contaminated
1. Increase to 70 psig minimum.
2. Reconnect tubing.
3. Check the tubing for kinks or damage.
Replace if worn or damaged.
4a. Make sure that the seal is in the proper posi-
tion and/or lubricate with a small amount of
petroleum jelly.
4b. O-rings left out of small Ø tie rods.
4c. O-ring missing between mounting block and
upper manifold.
4d. O-ring missing between mounting block and
replaceable head.
5. Make sure PT is activated. Both PT and BA/
PT (paint trigger) must be activated to trigger
the applicator on.
6. Make sure paint trigger (BA/PT) is actuated.
Both PT and BA/PT must be actuated to trigger
the applicator on.
1. Increase pressure.
2. Reinstall and tighten as required.
3. Examine, repair as required.
1. Start fluid flow before turning voltage on.
2. Repair/replace fittings and/or coiled fluid tube
as required.
3. Replace coil as required.
4. Clean with non-polar solvent.
