Hey just want to see if I am headed in for a service request. I own the TS75 for about 10 months and the TS55 for 5 months. Both saws have an oil leak coming from the vents next to the handle. About 4-5 drops of oil comes out. I wipe it down and 30 minutes later the vents have oil on them. Both saws are almost unused with less than 20 cuts on them. The TS75 is mounted in a CMS. Any ideas if this is normal?
