Installation; Grounding; Assemble The Spray Gun - Graco Fusion A Series Instructions Manual

Installation

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.
Spray gun: Ground through connection to a properly
grounded fluid hose and pump.
Proportioner: Follow the instructions in your
proportioner manual.
