tions, and F 5 shows the manifold connections.
IGURE
Connect the air and fluid lines as instructed.
WARNING
Electric Shock Hazard
To reduce the risk of electric shock or other
serious injury, the turbine air supply hose
must be electrically connected to a true
earth ground. Use only Graco Grounded
Air Supply Hose.
1. Connect the Graco Grounded Air Supply Hose (B)
to the gun's turbine air inlet (TA) and connect the
hose ground wire (A) to a true earth ground (N). The
gun turbine air inlet fitting has left-hand threads to
prevent connecting another type of air hose to the
turbine air inlet. See Accessories on page 52 for
further information about the hose.
2. Check the electrical grounding of the gun as
instructed on page 14.
3. Before connecting the fluid line (P1), blow it out with
air and flush it with solvent. Use solvent which is
compatible with the fluid to be sprayed.
