Caution
High temperatures and pressures result in accelerated fluid aging. Change fluid more frequently if
operating under extreme conditions.
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 indicates a filter change. Replace
all fluid lost during filter change.
For detailed filtration information, see Danfoss publication 520L0463 Fluids and Filtration. For
information on biodegradable fluids see Danfoss publication 520L0465 Biodegradable Hydraulic Fluids.
