Workshop Technical Tip: The most critical step when installing a new swing motor is strictly priming the housing with clean hydraulic oil before the initial startup. Running "dry" for even a few seconds can lead to irreversible piston seizure. Additionally, always check the permeability of the return line – high pressure in the housing (caused, for example, by a kinked hose) will immediately blow out the shaft seal.
