SERVICE

Pressure Relief Procedure
To reduce the risk of serious bodily injury, including
splashing in the eyes or on the skin, injury from
this
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.
