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, fluid leakage
will occur. Make sure the nut (L) is tight and that
nothing will pull or catch on the hose during opera-
tion.

on page 18.
9. Connect the other end of the hose as instructed in
the voltage isolation system manual. See Fig. 15.
WARNING
ELECTRIC SHOCK HAZARD
To reduce the risk of an electric shock,
the areas of the waterborne fluid hose
that are accessible to personnel during
normal operation must be covered by the outer
hose jacket (H). See Fig. 15.
CAUTION
The Graco warranty is void if the spray gun is con-
nected to a non-Graco voltage isolation system or if
the gun is operated above 60 kV.
