The conductive ring (33) 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.
