Assembly and Setup

1.Attach the handle (A, Fig. 1) to the handwheel (B, Fig. 1).

2.Turn blade tension hand wheel (C, Fig. 1) counter-clockwise to tension blade and clockwise to loosen the tension. A gauge on the upper wheel slide bracket (D, Fig. 1) indicates the approximate tension according to the width of the blade. The JWBS-20 comes with a 1” blade so the tension should be set at 1”.

Note: It is easier to adjust the bearing guides before mounting the table.
