stream of the air regulator to shut off gun
air.

fitting.
Ground the Gun
Check your local electrical code for detailed
grounding instructions.
Ground the gun through connection to a
Graco-approved conductive air supply hose.
Flush Before Using Equipment
The equipment was tested with lightweight oil,
which is left in the fluid passages to protect
parts. To avoid contaminating your fluid with
oil, flush the equipment with a compatible sol-
vent before using the equipment. See Flush,
page 9.
Check that your shop air provides
adequate air flow. See Technical
Data, page 20, for minimum cfm
requirements.
Recommended 5/16 in. (7.9 mm) ID
hose, optional 3/8 in. (10 mm) ID air
hose.
Set shop air pressure regulator (not
supplied) according to paint manu-
facturer’s recommendation. See
maximum compliant air pressure on
air cap.
Make sure no air restrictions, such as
low-volume cheater-valves, obstruct
the air flow. If an air adjusting valve is
desired, use a Graco adjustable air
valve (234784).
