Optimum operatingviscosity must be reached within approx. 15 minutes.Sizes 250 to 1000:νmin 60 SUS (10 mm2/s)short-term (t 3 min)at max. perm. temperature of tmax 195 F ( 90 C)νmax 4600 SUS (1000 mm2/s)short-term (t 3 min)at cold start (p 435 psi / 30 bar, n 1000 rpm, tmin -13 F / -25 C)Only for starting up without load. Optimum operatingviscosity must be reached within approx. 15 minutes.Note that the maximum hydraulic fluid temperature of 240 F(115 C) ( 195 F / 90 C for size 250 to 1000) must not be exceeded locally either (e.g. in the bearing area). The temperaturein the bearing area is - depending on pressure and speed - up to22 F (12 K) higher than the average case drain temperature.Special measures are necessary in the temperature range from 40 F and -13 F (-40 C and -25 C). Please contact us.For detailed information about use at low temperatures, seeRE 90300-03-B.The correct choice of hydraulic fluid requires knowledge of theoperating temperature in relation to the ambient temperature:in a closed circuit the circuit temperature, in an open circuit thetank temperature.The hydraulic fluid should be chosen so that the operating viscosity in the operating temperature range is within the optimumrange (νopt.) - the shaded area of the selection diagram. Werecommended that the higher viscosity class be selected ineach case.Example: At an ambient temperature of X C an operatingtemperature of 140 F (60 C) is set. In the optimum operatingviscosity range (νopt; shaded area) this corresponds to theviscosity classes VG 46 or VG 68; to be selected: VG 68.Please note:The case drain temperature, which is affected by pressure andspeed, is always higher than the circuit temperature or tanktemperature. At no point in the system may the temperature behigher than 240 F (115 C) for sizes 28 to 200 or 195 F (90 C)for sizes 250 to 1000.If the above conditions cannot be maintained due to extremeoperating parameters, we recommend flushing the case at portU or using a flush and boost pressure valve (see pages 66-67).
