Extension Rollers

N. EXTENSION ROLLERS

If you elected to wait to install the extension rollers during the assembly process, install the extension rollers now. Refer to the Assembly Section.

To adjust the extension rollers:

1.Lower the table and position a flat board, so it lays on the table and suspends over one of the extension rollers. See Figure 32.

2.Adjust the tightness of the mounting bolts and the depth of the setscrews on the exten- sion roller body. Various combinations of loosening and/or tightening the setscrews and bolts will level the extension rollers with the table. When the outermost extension roller touches the bottom of the board, stop adjusting and secure the extension roller to the body.

3.Repeat steps 1-3 for the other extension roller assembly.
