Triggering The Fluid Alone; Shutdown; Maintenance; Daily Care And Cleaning - Graco PRO AA5500SC Instruction Manual

Triggering the Fluid Alone

1. Shut off and relieve the air pressure to the atom-
ization air (A2) line, using the bleed-type air shut-
off valve.
2. Apply 50 psi (3.5 bar, 0.35 MPa) air pressure to
the cylinder air fitting (CYL) to trigger the fluid.

Daily Care and Cleaning

D Clean all parts with a non-conductive solvent, com-
patible with the fluid being sprayed. Conductive sol-
vents can cause the gun to malfunction.
D Methylene chloride is not recommended as a
flushing or cleaning solvent with this gun as it will
damage nylon components.
D Fluid in the air passages could cause the gun to
malfunction and could draw current and reduce
the electrostatic effect. Fluid in the power supply
cavity can reduce the alternator life. Whenever
possible, point the gun down while cleaning it. Do
not use any cleaning method which could allow
fluid into the gun air passages.
Do not point the gun up while cleaning it.
