I have been loaned an MK-101 wet saw while a contractor friend is off vacationing for 6 weeks. It is obvious that maintenance has not been one of the important line items on the task list. After cutting a few 12" tiles I found that the saw is out of true by 1/8" over 12".
So I'll spend some time cleaning it up and truing it. I believe in returning tools in better condition than I borrowed them, so I don't mind. Besides, I want my job to look good even if he doesn't care about his.
How does one know if the blade needs to be dressed or replaced. MK's manual says that a wandering cut indicates the blade needs to be dressed. Fair enough. But what are the signs that the blade needs replacement?
