Ground the Gun
Check your local electrical code and pump
manual for detailed grounding instructions.
Ground the spray gun through connection to a
Graco-approved grounded fluid or 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
10 .
At least one hose must provide a static
ground to the gun.
• Recommended 5/16 in. (7.9 mm) ID
hose, optional 3/8 in. (9.5 mm) ID hose.
• Check that your shop air provides ade-
quate air flow. See Technical Data,
page
23 , for minimum cfm
requirements.
• Set shop air pressure regulator (not
supplied) according to fluid manufac-
turer’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.
