PROBLEM CAUSE SOLUTION
Narrow Fan
Wide Fan Material too cold, nozzle too large
or air pressure low. Heat Material, use smaller
nozzle, or as a last resort
increase pump pressure.
Resin filter clogged. Disassemble and clean the resin
filter.
Air pressure too high. Lower pressure then increase
pressure to the desired fan.
Nozzle too small or too wide. Change nozzle.
Round fan Orifice in nozzle worn, clogged,
or damaged. Push fine wire through orifice
from back side. Use fingernail to
clean material form “V” shaped
notch in front. Soak hardened
material in solvent. If notch is
rough or worn, replace nozzle.
Air-assist pressure too high. Decrease air-assist pressure.
Excessive Misting
