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.
