Never service or disassemble the unit or
unit components without relieving hydraulic system
pressure rst. The high pressures involved could
cause serious injury.
NOTE: If this pump was purchased separately (not part
of a system), consult your sales representative for com-
patible dispensing accessories which will best match the
application. All accessories must be able to withstand the
maximum pressure developed by the pump.
A replacement warning label is available upon request,

GENERAL DESCRIPTION
The 4.125 square inch hydraulic motor is a general purpose
power unit and is used on many ARO industrial 2-ball, 4-ball
and chop-check pumps. It utilizes tie rod type construction
for serviceability and connects to the various lower pump
ends by tie rods.
Due to frictional losses in the system, a greater horsepower
is required to run the motor. Power supplies generating less
than shown as required in the Performance Specifications
above will work with the motor but at a reduced pressure or
cycle rate.

OPERATING AND SAFETY PRECAUTIONS
WARNING
READ THE GENERAL INFORMATION MAN-
UAL INCLUDED FOR ADDITIONAL OPERATING AND
SAFETY PRECAUTIONS AND OTHER IMPORTANT IN-
FORMATION.
WARNING
EXCESSIVE MATERIAL PRESSURE. Can cause
equipment failure resulting in severe injury or prop-
erty damage. Do not exceed the maximum material
pressure of any component in the system.
WARNING
A pressure relief valve must be used to pre-
vent over-pressurization of the system and possible
component rupture.
WARNING
Excessive hydraulic oil temperature can
cause re. The unit is rated for operation up to 130° F
(54° C). Be sure return lines are sized larger than sup-
ply lines and similarly pressure rated.
