1) Ensure motor case is fi lled with oil prior to start-up.
2) For installation and maintenance details, please see instruction
manual 15215-B.
3) For any other fl uid type contact the Engineering Department at
Bosch Rexroth, Glenrothes. For more information on hydraulic fl u-
ids, see datasheets 90220 and 90223.
4) Extension of the allowable temperature range may be possible de-
pending on specifi cation. Please consult Bosch Rexroth Engineer-
ing Department in Glenrothes for further details.
5) Maximum values should only be applied for a small portion of the
duty cycle. Please consult Bosch Rexroth Engineering
Department in Glenrothes for motor life calculations based on par-
ticular operating cases.
6) When operating motors in series, please consult Bosch Rexroth
Engineering Department in Glenrothes.
7) For continuous operation at speeds <5 rpm please consult Bosch
Rexroth Engineering Department in Glenrothes.
8) Based on nominal no-load Δp of 20 bar in full-displacement mode.
9) Warning! During the running in period of the motor (min. 20 hrs) it
should not be run unloaded at >100 rpm.
Notice
▶ Motor performance values are based on theoretical
calculations.
▶Effi ciencies are not taken into consideration for theo-
retical calculations.
▶ Brake torque accounts for tolerances. Values are based
when used with standard mineral oil (HLP)
