*Included in Repair Kit 218–967.

**Extra warning tags and labels are supplied at no charge.

Included in Repair Kit 220–391. Read and follow the Old/New

Style Resistor Stud and Electrode Warning, at left.

See HOW TO ORDER REPLACEMENT PARTS on page 29.

Old/New Style Resistor Stud and Electrode
To reduce the risk of sparking, which could cause fire
or explosion, BE SURE the electrode and stud you
install are black. The old style electrode and stud in
the Series A Guns were white. DO NOT mix old style
parts with new style parts.

WARNING

When servicing use only genuine Graco replace-
ment parts. Use of other parts or any alteration or
modification of this equipment could cause it to
malfunction, which could result in serious injury,
fire, explosion, or property damage.
