The conductive ring (9) is a conductive metal
contact ring, not a sealing o-ring. To reduce
the risk of fire, explosion, or electric shock:
• Do not remove the conductive ring except
to replace it.
• Never operate the gun without the conductive
ring in place.
• Do not replace the conductive ring with
anything but a genuine Graco part.
5. Trigger the gun and remove the fluid seat housing
(24), using the multi-tool (61).
