Hydraulic fluid
Refer to Danfoss publication
Fluids and Filtration BLN-9887 or 520L0463. For information on
biodegradable fluids refer to Biodegradable Hydraulic Fluids 520L0465. See Fluid and Filter Maintenance
on page 20 for recommended fluid and filter change intervals.
Temperature range

Intermittent (cold start): - 40° C [- 40° F]
Continuous: 82° C [180° F]
Maximum
(2)
: 104° C [220° F]
(1) Hydraulic fluid viscosity must be maintained within the prescribed limits.
(2) As measured at the hottest point in the system, e.g. drain line.
