Fluid and filter maintenance
To ensure optimum life of Series 45 products, 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. Water in the fluid may be noted by a cloudy or milky appearance or free water
in the bottom of the reservoir. Rancid odor indicates the fluid has been exposed to
excessive heat. Change the fluid immediately if these conditions occur. Correct the
problem immediately.
Change the fluid and filter per the
vehicle / machine manufacturer's
recommendations or at these intervals:
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 the fluid is changed or when the filter indicator shows that it is
necessary to change the filter. Replace all fluid lost during filter change.
