Fluid and filter recommendations
To ensure optimum life, perform regular maintenance of the fluid and filter. Contaminated fluid is the
main cause of unit failure. Take care to maintain fluid cleanliness when servicing.
Check the reservoir daily for proper fluid level, the presence of water, and rancid fluid odor. Fluid
contaminated by water may appear cloudy or milky, or free water may settle in the bottom of the
reservoir. Rancid odor indicates the fluid was exposed to excessive heat. Change the fluid immediately if
these conditions occur. Correct the problem immediately. Inspect vehicle for leaks daily.
Change the fluid and filter per the vehicle/machine manufacturer’s recommendations or at these
intervals:
We recommend first fluid change at 500 hours.
Caution
High temperatures and pressures accelerate fluid aging. More frequent fluid changes may be required.
Change the fluid more frequently if it becomes contaminated with foreign matter (dirt, water, grease,
etc.) or if the fluid is subjected to temperature levels greater than the recommended maximum.
Dispose of used hydraulic fluid properly. Never reuse hydraulic fluid.
Change filters whenever you change the fluid or when the filter indicator shows that it is necessary to
change the filter. Replace all fluid lost during filter change.
