Checking/Adjusting
Table Parallelism
Table parallelism has been adjusted at the fac-
tory and should not require adjustment when the
machine is new.
We only recommend adjusting table parallelism
if absolutely necessary due to factors that may
cause the factory setting to change. Adjusting
the table parallelism can take a fair amount of
patience.
IMPORTANT: DO NOT adjust the table unless
you are having trouble sanding your workpiece
to a uniform thickness and have eliminated all
other possible causes. For instance, a sanding
or conveyor belt that is unevenly worn should be
replaced before adjusting table parallelism.
The four corners of the table can be independent-
ly adjusted up or down to achieve parallelism with
the frame by adjusting the elevation leadscrew
flanges (see Figure 94) or repositioning the table
elevation sprockets (see Figure 95).
Figure 94. Table elevation leadscrew flanges
located on underside of table.

If a table adjustment is needed, take precise
notes on the positioning of the table elevation
flanges, sprockets, and leadscrews by marking
them. This will allow the original setting to be
restored if needed.
