Connect the Fluid Hose

NOTE:

DA Graco waterborne fluid hose must be used between the voltage isolation system fluid outlet and the spray gun fluid inlet. See page 48 to order the Graco waterborne fluid hoses and the hose replacement parts.

DBefore connecting the fluid supply line to the gun, blow it out with air, and flush it with water to remove contaminants. Flush the gun before using it.

WARNING

ELECTRIC SHOCK HAZARD

To reduce the risk of an electric shock, install only one continuous Graco water- borne fluid hose between the isolated

fluid supply and the spray gun. Do not splice hoses together.

1. For the fluid hose to seal properly and be held

securely, the hose must be stripped and as-

sembled to the dimensions shown in Fig. 4. Refer

also to Fig. 29, page 42. A new Graco waterborne

fluid hose comes fully assembled to the proper

CAUTION

Be careful not to cut into the inner hose layer (K) when stripping the hose. Nicks or cuts in the tube will cause premature hose failure.

2.Inspect the condition of the o-rings (G) on the hose barbed-fitting. Replace the o-rings if they are worn or damaged.

3.Unscrew the hose ferrule housing (79) from the gun fluid inlet fitting, and slide the nut onto the barbed-end of the hose. Refer to Fig. 5.

4.Apply a light coat of dielectric grease (supplied with the gun) to the o-rings (G) and to the entire length of the inner hose layer (K). See Fig. 4.
