Figure 13. Underside of table.
Figure 14. Understanding sprocket movement.
To adjust the table more than .016":
1. Remove the front cabinet cover.
2. On the underside of the table there is a
chain drive and five sprockets as shown in
Figure 13. The four sprockets in the corners
control the movement of the table columns.
The fifth sprocket is the idler sprocket that
controls the chain tension. Loosen the two
bolts on the idler sprocket bracket (as
shown in Figure 13) to loosen the chain so
that each sprocket can be rotated on its
own. Make sure to hold the chain away from
the sprocket while you adjust it.
3. Moving the sprockets clockwise lowers the
table and moving them counter-clockwise
raises the table. Each tooth on the corner
sprockets equals .016" of vertical movement
when the cogs are turned (see illustration in
Figure 14). Make sure, as you adjust each
sprocket, that you count the number of
teeth that pass a fixed point.
Knowing how far you turned one sprocket
will help you keep the other side consistent
if you are adjusting two columns together.
4. After you have the table adjusted to within
.016" from front-to-back and from side-to-
side, tighten the chain so all of the slack is
removed.
5. Now follow the previous instructions for
adjusting the table when it is less than .016"
from its proper position.
Do not connect power to
the machine while
performing adjustments.
Failure to follow this
warning may result in
serious personal injury.
