Operation; Grounding; Air Hose Connection; Safety Lock - Graco GX-7A Instructions Manual

Operation

To prevent accidental gun operation, always
disconnect air supply before servicing gun or anytime
gun is not in use.

Grounding

The equipment must be grounded to reduce the risk
of static sparking. Static sparking can cause fumes to
ignite or explode. Grounding provides an escape wire
for the electric current.
Follow local codes, regulations, and your proportioner
manual for detailed grounding instructions.
Spray gun: ground the spray gun through connection to
a properly grounded fluid hose and pump.

Air Hose Connection

To connect air hoses: pull back the sleeve of the
female fitting, insert the male fitting and slide the sleeve
forward to secure connection.
To disconnect air hoses: pull back the sleeve of the
