Expert "Life-Saving Detail": Case Drain Connection
For a motor as powerful as the 50M255A, the Case Drain is not optional—it is a "life-saving" necessity for your hydraulic system.
Risk Reminder: Never plug the case drain port on a 50M series motor. An external drain line must be connected directly to the reservoir. Failure to do so will cause instantaneous internal pressure buildup, blowing out the shaft seal and causing permanent internal damage within minutes of startup.
