Centre of pattern is
too narrow
1. Paint is too thin or not sufficient.
2. Atomization air pressure is too high.
1. Regulate paint viscosity.
2. Reduce air pressure.
Width of spray
pattern is too narrow
1. Paint is too thick.
2. Atomization air pressure is too low.
1. Regulate paint viscosity.
2. Increase air pressure.
Air leakage from air
cap when trigger is
not pressed
1. Air inlet valve or seat is contaminated.
2. Inlet valve stem is stuck.
3. Air inlet valve or seat is worn or
damaged.
