Repair
If the regulator fails to operate, operates roughly,
vibrates, etc., follow the above Warning. Remove the
regulator and service as follows:
Disassemble the regulator. See the Repair Kit
Drawings on page 7.
Wash the parts with household soap and water or
denatured alcohol. Wipe the parts dry with a clean, soft,
dry rag. Use compressed air to blow any dirt and
contaminants out of the regulator body.
Inspect parts for damage or wear. Replace any
damaged parts.
Lubricate the bearing area, adjusting screw threads. and
spring ends with No. 2 lithium-base grease. Reassemble
the regulator.
When installing the diaphragm, be sure that the disc is
firmly in place. Install the disc stem into the center hole of
the diaphragm. Torque the spring housing to 45 in-lb
(51N•m).
Relieve air and fluid pressure before servicing the
regulator.
To help prevent serious injury from pressurized fluid,
such as skin injection, splashing fluid, and moving
parts, relieve pressure on both the inlet and outlet
sides of the regulator before servicing.
Inlet: Turn off the air supply and depressurize the air
line connected to the inlet.
Outlet: Open the bleed-type master air valve
(required on the outlet side) to relieve system air
pressure, and trigger the gun or dispense valve and
open any fluid drain valves to relieve fluid pressure.
NOTICE
Do not use trichloroethylene, acetone or similar
solvents to clean the regulator. These solvents could
damage the regulator parts.
