Replacing the operating fluid of the sewage pump
WARNING
Risk of injury from pressurised operating fluid!
There can be a high pressure in the motor! This pressure is released when the screw plugs are removed. If the screw plugs are removed carelessly, the screw plugs can be thrown out at high speed. Because of the high pressure, hot operating fluid can also splash out. Follow these points:
- Wear protective equipment.
- Cool down the motor to ambient temperature.
- Follow the order of work steps.
- Remove the screw plugs slowly. If pressure is released during removal of the screw plugs (hissing or whistling sound), stop work!
- When the pressure is released, remove the plugs fully.
Make sure to replace specified operating fluid depending on the motor type.
