NOTICE
The table has been adjusted at the factory and
should require no further attention. However, we
recommend verifying its parallelism with the sanding
roller.
Table Parallelism
Thecornersof thetablecan beindependentlyadjusted
up or down. By disconnecting the chain and turning the
pertinent table elevation screw sprocket (Figure 44),
table parallelism can be achieved.
Adjustingthetableparallelismcanbeaverytedioustask
thattakesagreatamountofpatience.DONOTadjustthe
table unless you are having trouble sanding your work-
piece to a uniform thickness.
Ifatableadjustmentisneeded,takeprecisenotesonthe
positioning of the table elevation screws. This will allow
theoriginalsettingtobere-established.
To adjust the table parallelism, do these steps:
1. Pass a 37" wide board through the sander until the
entire surface of the board is making contact with
the sanding belt.
2. Measure the thickness of the board at various points
around the edge.
3. If there is a variation of thickness, the table can be
adjustedaccordingly.
4. Disconnect the sander from the power source!
—For minor adjustment, loosen the table mounting
bolts shown in Figure 45 and rotate the elevation
screw flange.
—Formajoradjustment, mark the chain location on all
sprockets, remove the chain from only the sprocket
tobeadjusted, andturnthesprocket counterclock-
wise to raise the table. One quarter of a turn raises
or lowers an elevation screw approximately 0.020".
5. Reinstall the chain, tighten the bolts, and test the
machine.

NOTICE
When adjusting the left front eleva-
tion screw, make the same adjustment
to the left rear elevation screw. This
ensures the height from the front to the
back of the table remains unchanged.
Do the same when adjusting the right
elevation screws.
