22/131 Bosch Rexroth AG | Electric Drivesand ControlsRexroth MKE Synchronous Motors | Project Planning ManualSafety Instructions for Electric Drives and ControlsWARNINGRisk of injury by improper handling of pressurized lines!●●●●●Do not attempt to disconnect, open or cut pressurized lines (risk of explosion).Observe the respective manufacturer's operating instructions.Before dismounting lines, relieve pressure and empty medium.Use suitable protective equipment (safety goggles, safety shoes, safetygloves, for example).Immediately clean up any spilled liquids from the floor due to the risk ofslipping.Environmental protection and disposal! The agents (e.g., fluids)used to operate the product might not be environmentally friendly.Dispose of agents harmful to the environment separately from otherwaste. Observe the national regulations of your country.
