WEN 3912 10 inch band saw - Manual (Page 16)

Assembly and adjustments (continued)
If a blade is being replaced with a new one of a different size, the adjustment described above
may fall out of range and further adjustment may be required as follows:
Loosen the hex cap screw (G, not visible) with a 10mm wrench and adjust the entire assembly
backwards or forwards to clear the back of the saw blade. Tighten screw (G), and then fine-tune
the adjustment by repeating the first part of this step.
6. Secure the roller guide (A) by tightening the thumbscrew (B, upper guide) or setscrew (B,
lower guide).
