IMPORTANT: Prior to performing any main-
tenance procedure, the following safety pre-
cautions must be observed. Personal injury
may occur.
WARNING
Do not use halogenated hydrocarbon solvents
such as methylene chloride or 1,1,1-trichloroethane 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 perform-
ing any overhaul procedure.
•
Disconnect the hydraulic supply line from the pump
motor.
•
Into an appropriate contai n er, 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.
