Inlet pressure

Minimum pressure, continuous = 0.8 bar absolute [6.7 inch Hg vac] (at reduced maximum pump speed)
Minimum pressure, cold start = 0.5 bar absolute [15.1 inch Hg vac]

Pressure compensator valve setting

Setting 100 and 130 cc
Minimum 100 bar [1450 psi]
Maximum 310 bar [4495 psi]

Case pressure

Maximum continuous: 0.5 bar [7 psi] Above inlet
Intermittent: 2 bar [29 psi] Cold start

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
on page 20 for recommended fluid and filter change intervals.
