Overhaul

NOTE

: Refer to 

Figure 2 

for component

identification on all overhaul procedures.

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 pump. An explosion can result
within an enclosed device capable of containing
pressure when aluminum and/or zinc-plated parts
in the pump 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 injury.
Read each step of the instructions carefully. Make
sure a proper understanding is achieved before
proceeding.
