(0.35 bar, 35 kPa) when triggered. Check spray pat-
tern, then slowly increase air pressure until tails are
completely atomized and pulled into spray pattern.
Do not exceed 100 psi (0.7 MPa, 7 bar) air pressure
to gun.

sparking and injury from splashing, always flush at
lowest possible pressure.

stroke to keep fluid from drying on the exposed dis-
placement rod and damaging throat packings.
