Troubleshooting Guide
MC800 Controller Possible cause and correction
Contaminated air supply. Remove the controller cover to access
the regulator. Remove the brass hex plug, spring and poppet
from the regulator. Clean poppet and reinstall the poppet, spring
and plug.
Tank pressure may be too low. Minimum operating tank air
pressure is 12 psi (0.83 bar).
Hose connector may not be pushed fully into the fluid outlet fit-
ting on the rear panel of the controller. Ensure connector is firm-
ly seated.
Check fluid hose for kinks.
Supply pressure to controller must be at 4.1 bar (60 psi).
Air cap may be clogged. Be sure oil tank filter is clean. Remove
air cap and clean the inside of the air cap and the outside of the
nozzle. Refer to Spray Valve Maintenance on page 22.
Nozzle air pressure regulator may be set too low. Increase pres-
sure as needed. Normal working range is within 8 to 15 psi
(0.55 to 1.03 bar).
Dripping can be caused by improper seating of the needle in the
nozzle. Clean the needle and nozzle, and replace any worn or
damaged parts.
Ensure nozzle is tight to seat the needle properly.
