Overhaul
NOTE: Refer to Figures 2-A and 2-B 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
when aluminum and/or zinc-plated parts in the
pump come in contact with halogenated hydrocar-
bon 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.
