1. Remove the gun air inlet fitting (35). See FIG. 3..
Fig. 3. Connect the Fluid Hose
In a shielded hose system, if a hose failure occurs
where high voltage arcs through the inner tube, voltage
will be discharged to ground through the conductive
hose layer. When properly installed, the conductive hose
layer is grounded through its connection to the grounded
enclosure.
2. For the fluid hose to fit properly, it must be stripped
and assembled to the dimensions in F
IG. 4.. Push
the inner tube (T) into the fitting (F) until the tube
bottoms. A new Graco waterborne fluid hose comes
fully assembled to these dimensions.

3. Generously apply dielectric grease (40) to the o-ring
(107) and the threads of the fitting (106). Pull the fit-
ting back 1-1/2 in. (38 mm) and apply grease to the
exposed PTFE hose to fill the area between the
hose and the fitting. Make sure the barrel inlet is
clean and dry, then screw the fitting into the fluid
inlet of the gun barrel (16). See F
IG. 3..
4. Loosen the strain relief nut (102) so the bracket can
move freely on the hose.
5. Align the bracket (104) holes with the air inlet and
exhaust outlet. Secure with the air inlet fitting (35).
Tighten the strain relief nut (102) to secure the hose.
6. Check that the nut (105) is tightened securely to the
ferrule housing (103).
7. Press the exhaust tube (38) onto the barbed
adapter (A). Secure with the clamp (39).
8. Connect the other end of the hose to the isolated
fluid supply as follows:
CAUTION
Be careful not to cut into the inner tube (T) of the
hose when stripping the hose. Nicks or cuts in the
PTFE tube will cause premature hose failure.
