Why is the oil in my BUSCH R 5 RA 1600 B black?

If the oil in your BUSCH Water Pump is black, it could be due to several reasons. The oil change intervals might be too long, in that case you should contact Busch to flush the machine. The inlet filter might be defective and need replacement. Also, the machine might be running too hot; refer to the troubleshooting steps for that specific problem.
