Ok....you power wash your saw? And use lemon scrubbing bubbles? Are there no spots where water shouldn't get on a saw? Right into those air slots? I was always taught to keep machinery out of water??
Saws ride in the back of log trucks on skidders atvs etc. here In the elements usually Most are not babied To even work on a loggers saw I have to pressure wash them first To even see damage or to repair them Saws are tough Just blow them out with an air compressor after washing.
