I bought one and it was delivered this morning. Not impressed.
It is supposed to be capable of cutting pieces 127x127 but I cannot for the life of me get the saw to open up enough to get anything more than 75mm thick under the blade if I am to use the supplied vice. Yes, the throat and exposed blade are over 127mm each, so one can cut 127mm pieces freehand but neither the listing nor the manual state this. It states "Cutting Width at 90" is 127x127 and "Cutting Width at 45" is 127x40. No idea how to achieve this.
The second nail in the coffin is the fact that the "Transport Locking Pin" locks in position any time the blade is lowered. And it needs to be released to raise the blade. And it locks in the upper position any time the blade is raised. And it needs to be released to lower the blade. And it locks in position any time the blade is lowered. And it needs to be released the raise the blade. And oh my God I think I'm going to send it back. The manual implies that the locking pin can be released permanently when not transporting it but, as per the first paragraph, I cannot for the life of me achieve this.
It may be user error but the buttocks end of the saw meets the base when it the blade is fully raised and I still cannot get more than 75mm in, so I don't know what else to try.
