We put 4 new Imperial 525 machines in about a year ago. All 4 machines have oil leaks from their bearings. This can be a safety issue because the oil leaks on the brake drum. If not monitored and cleaned regularly the oil can really build up on the drum. Apparently, Imperial is fully aware of this issue and has crews traveling all over the world fixing this problem. If you installed Imperial machines within the past 2 years you should really look into this and have it repaired.
