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

cator spray head is not in
place or there is an ex-
tremely tight fit between the
