for
component identification on the major com-
ponents of the valve assembly.
Prior to performing any maintenance procedure, the
following safety precautions must be observed. Personal
injury may occur.
WARNING
Do not use halogenated hydrocarbon sol-
vents such as methylene chloride or 1,1,1 trichlo-
roethane in this valve assembly. An explosion can
result within an enclosed device capable of con-
taining pressure when aluminum and/or zinc-
plated parts come in contact with halogenated
hydrocarbon solvents.
Release all pressure within the system prior to
performing any overhaul procedure.
• Disconnect the air supply line from the pump
motor.
• Into an appropriate container, operate the
control valve to discharge remaining pressure
within the system.
Never point a control valve at any portion of your
body or another person. Accidental discharge of
pressure and/or material can result in personal
injury.
Read each step of the instructions carefully. Make
sure a proper understanding is achieved before
proceeding.
