RECIRCULATION SYSTEM
5.1 Overview
The oil recirculation circuit is a cooling and filtration system that provides properly conditioned
oil to the main hydraulic system. Hydraulic oil is maintained at the proper operating temperature
and condition by continuous recirculation.
System components include the water modulating valve, recirculation pump, heat exchanger, oil
filter assembly and the hydraulic oil reservoir.
5.2 Operation
Cooling water is introduced through the 1/2-inch NPT connection on the bulkhead of the machine
where the water modulating valve regulates the cooling flow to the heat exchanger. The valve is
factory set, but may require adjustment to maintain the operating oil temperature at 115° F (46°
C). Oil temperature can be visually monitored from a dual scale level/temperature sight gauge on
the side of the hydraulic oil reservoir.
