IMPORTANT: 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-

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

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 dis-

charge 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.
