Overhaul

NOTE: Refer to Figure 2-A and 2-B 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.
