WARNING
PRESSURIZED EQUIPMENT HAZARD
To reduce the risk of an injury, follow the Pressure Relief Procedure on page 16 before checking or servicing any part of the system and whenever you are instructed to relieve the pressure.
Damaged hoses or hoses that have a
1.Discharge the voltage as instructed on page 16.
2.Relieve the system pressure as instructed on page 16.
3.Disconnect the fluid hose from the gun and voltage isolation system.
4.Cut off the damaged end of the hose. If the hose has a
5.Carefully cut through the outer hose jacket (H) and peel it back about 12 inches (105 mm). Do not cut into the conductive layer (J) of the hose.
6.Cut through the first 1/2 inch (12.7 mm) of the conductive hose layer (J) to create an edge to hold onto. Peel back the conductive hose layer by unwrapping it in a spiral pattern. Cut it off at the dimension shown in Fig. 29.
7.Cut off the inner hose layer (K) to the dimension shown in Fig. 29.
8.Inspect the hose for any nicks or cuts. Any nicks or cuts into the inner hose layer (K) will weaken the dielectric strength of the hose and shorten the service life. Repeat the above procedure if any damage is found.
9.Install a new barbed fitting by applying red dielec- tric grease to the outside of the barbs, and press- ing the fitting into the gun end of the hose. Refer to the drawing of the Waterborne Fluid Hose Assem- bly on page 48.
