7. To ensure the o-rings (C) on the barbed-fitting are
seated in the gun, loosen the nut (D) and push the
fluid hose into the gun until the barbed-fitting
bottoms out. See Fig. 40.
WARNING
ELECTRIC SHOCK HAZARD
To maintain grounding continuity, the
conductive hose layer (E) must be
engaged in the fitting (P1) when the nut
(D) is tightened. See Fig. 40. Failure to properly
install the hose into the fitting could result in an
electric shock.
8. Tighten the nut (D) firmly with a wrench to about
55 in-lb (6.2 NSm). Pull back on the hose to make
sure it is secure.
CAUTION
If the hose comes loose from the fitting (P1), fluid
leakage will occur. Make sure the nut (D) is tight and
that nothing will pull or catch on the hose during
operation.
