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 has been exposed to excessive heat. Change the fluid and
correct the problem immediately if these conditions occur.
•
Inspect vehicle for leaks daily. Change the fluid and filter per the vehicle/machine manufacturer's
recommendations or at intervals shown in the table. We recommend first fluid change at 500 hours.
Fluid and filter change interval
Reservoir type
Max oil change interval
Sealed
2000 hours
Breather
500 hours
High temperatures and pressures will result in accelerated 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 with the fluid or when the filter indicator shows it's necessary.
•
Replace all fluid lost during filter change.
