High Pressure Lubricant Pump

IMPORTANT: Prior to performing any maintenance procedure, the

following safety precautions must be observed. Personal in}ury

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 con-

taining 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 anoth-

er person. Accidental discharge of pressure and/or material can

result in injury.

Read each step of the instructions carefully. Make sure a prop-

er understanding is achieved before proceeding.
