WARNING

Fire, Explosion, and Electric Shock Hazard

The nozzle contact ring (7a) is a conductive contact ring, not a sealing o-ring. To reduce the risk of sparking or electric shock, do not remove the nozzle contact ring (7a) except to replace it and never operate the gun with- out the contact ring in place. Do not replace the contact ring with anything but a genuine Graco part.

Use non-silicone grease, Part No. 111265, on the small o-ring (7b). Do not over-lubricate. Do not lubricate the contact ring (7a).

4.Lightly lubricate the o-ring (7b). . Install it and the contact ring (7a) on the nozzle (7).

Make sure the electrode needle (29) is finger-tight (page 26).

5.Trigger gun while installing the fluid nozzle (7) with the multi-tool (37). Tighten until the fluid nozzle seats in the gun barrel (1/8 to 1/4 turn past hand-tight).

6.Install the air cap (9) and retaining ring (27). Make sure the u-cup (27a*) is in place with the lips facing forward.

7.Test gun resistance, page 17.
