Barrel Installation

See F 36
IGURE
1. Verify the gasket (9) and grounding spring (6) are in
place and the gasket air holes are aligned properly.
Replace the gasket if damaged.
2. Make sure the spring is in place on the tip of the
power supply (7). Liberally apply dielectric grease to
the tip of the power supply. Place the barrel (1) over
the power supply and onto the gun body (10).
3. Tighten the two barrel screws (19) oppositely and
evenly (about a half turn past snug or 20 in-lbs). Do
not over-tighten.
NOTICE
To avoid damaging the gun barrel, do not over-tighten
the screws (19).
4. Install and adjust the actuator arm (15), jam nut
(16a), and adjustment nut (16b). See page 42.
5. Test gun resistance, page 29.
6. Install the gun shroud (26) and air cap, page 39.
7. Install the gun onto the manifold. See page 38.

Power Supply Removal and
Replacement
• Inspect the gun body power supply cavity for dirt or
moisture. Clean with a clean, dry rag.
• Do not expose gasket (9) to solvents.

2. See Barrel Removal, page 42.
NOTICE
Be careful when handling the power supply (7) to
avoid damaging it.
3. Grasp the power supply (7) with your hand. With a
gentle side to side motion, free the power sup-
ply/turbine assembly from the gun body (10), then
carefully pull it straight out.
Smart models only: disconnect the flexible circuit
(30) from the socket at the top of the gun body.
4. Inspect the power supply and turbine for damage.
5. To separate the power supply (7) from the turbine
(8), disconnect the 3-wire ribbon connector (PC)
from the power supply. See F
Smart models only: disconnect the 6–pin flexible
circuit (30) from the power supply.
Slide the turbine up and off the power supply.
6. See Test Power Supply Resistance, page 29.
Replace the power supply if necessary. To repair
the turbine, see Turbine Removal and Replace-
ment, page 44.
NOTICE
To prevent damage to the cable and possible inter-
ruption of the ground continuity, bend the turbine's
3–wire ribbon cable (PC) upward and back, so the
bend faces the power supply and the connector is at
the top.
7. Connect the 3-wire ribbon connector (PC) to the
power supply.
Smart models only: connect the 6–pin flexible cir-
cuit (30) to the power supply.
