SERVICE

WARNING

Installing and servicing this equipment requires access to parts which may cause electrostatic shock or other serious bodily injury if the work is not performed properly. Do not install or service this equipment unless you are trained and qualified.

NOTE: Check all possible remedies in the Troubleshooting Charts before disassembling the gun.

Flush the Gun and Relieve Pressure

WARNING

To reduce the risk of fire, explosion, or electrostatic shock, BE SURE the turbine air (electrostatics) is off before flushing the gun.

CAUTION

Methylene chloride is not recommended as a flushing or cleaning solvent with this gun as it will damage nylon components.

Before removing the gun for service, flush it by alternat- ing solvent and air. Then follow the Pressure Relief Pro- cedure, at right.

Service Notes:

S If the plastic parts of the gun must be held in a vise, ONLY use padded vise jaws to avoid damaging parts.

S ALWAYS remove the gun from the worksite for service or repair. The service or repair area must be clean.

WARNING

Pressure Relief Procedure

To reduce the risk of serious bodily injury, including splashing in the eyes or on the skin, injury from moving parts or electrostatic shock, always follow this procedure when shutting off the system, when checking or servicing any part of the spray system, when installing, cleaning or changing fluid nozzles, and whenever you stop spraying.

1.Turn off the air to the control module, except for the manifold air. If the air pilot fluid regulator is used, air pressure is needed at the regulator air inlet to relieve pressure in the fluid line.

2.Turn off the fluid supply to the gun.

3.Trigger the gun into a grounded metal waste container to relieve fluid pressure.

4.Open the pump drain valve, having a waste container ready to catch the drainage.

5.Leave the pump drain valve open until you are ready to spray again.

Remove the Gun from the Manifold and the Mounting Bracket (See Fig 14 )

1.Remove the air cap/air cap nut assembly and the gun shroud.

2.Loosen the three socket head cap screws and the button head screw, using the ball end wrench (46) supplied.

3.Remove the gun from the manifold.
