YDRAULIC IL
Factory filled oil is tested for cleanliness. Hydraulic oil is the
lifeblood of the system. Particles in the oil will devastate any
hydraulic system overtime, therefore regular oil changes will
most likely extend the life of components and equipment.
Oil should be replaced when it becomes oxidized, when it has a
significant change in color and/or becomes milky or cloudy.
Laboratory analysis is an effective method of obtaining accurate
information on the cleanliness of hydraulic oil.
The renewal interval of hydraulic oil may be determined by
operational duty cycle, operating conditions and local
maintenance schedule.
It is recommended to replace the hydraulic oil at least once a
year or when contaminated.

Supply oil from the tank enters the hydraulic pump through the
suction line. Pressurized oil exits the hydraulic pump through
the pressure line directly to the directional control valves. A
return line exits the hydraulic pump and runs excess oil back to
the oil tank. Refer to the pump OEM for more information.
