CAUTION

BE SURE to hold the front end of the gun up while removing the nozzle and resistor stud. This helps drain the gun and prevent any paint or solvent left in the gun from entering the air passages.

1. Point the front end of the gun up while removing the

fluid nozzle (14) and resistor stud (2) assembly with

the nozzle wrench (48). This helps drain the gun and

The resistor stud contact ring (D) is a conductive con- tact ring, NOT a sealing o-ring. To reduce the risk of sparking, which could cause fire, explosion, or elec- trostatic shock and result in serious injury, DO NOT remove the contact ring from the resistor stud or op- erate the gun without the contact ring in place. DO NOT replace the resistor stud with anything but a genuine Graco part.

To install the resistor stud:

3.Lightly lubricate the o-ring (31) with petroleum jelly and install it on the resistor stud (2).

4.Using an 8 mm hex key (A), install the resistor stud

(2) in the fluid nozzle (14). T

Make sure the electrode (28) is tightened properly , as shown in Fig 17 , page 20.

5.Install the fluid nozzle (14) and resistor stud (2) assembly with the nozzle wrench (48). Tighten until the fluid nozzle seats in the gun barrel (1/8 to 1/4 turn past hand-tight).

6.Install the air cap assembly (6, 16, 43), o-ring (12),

and retaining ring (9). T est gun resistance as instructed on page 16.
