IMPORTANT: Prior to performing any
maintenance procedure, the following
safety precautions must be observed. Per-
sonal injury may occur.
WARNING
Do not use halogenated hydrocarbon
solvents such as methylene chloride or 1,1,1
trichloroethane in this motor. 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
motor.
• Into an appropriate container, operate the
control valve to discharge remaining pres-
sure 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.
