Overhaul
NOTE
Refer to fig. IPB 1 and IPB 2, pages 17
and 18 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
solvents such as methylene chloride or
1,1,1-trichlorethane in this pump.
An explosion can result within an
enclosed device capable of containing
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 air supply line from pump
motor.
• Operate control valve to discharge
remaining pressure within system
into an appropriate container.
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.
