W1756/W1757 43" Wide-Belt Sander
SERVICE
Model W1757: Loosen the roller lock nuts on the
front sanding drum infeed and outfeed pressure
rollers (
Figure 43). Turn the adjustment bolts and
studs on both sides of the sander to lower the infeed
and outfeed pressure rollers until they just touch the
board.
Note: DO NOT continue to lower the roller beyond
that point.
7. Tighten the roller lock nuts and recheck your
settings.
8. Connect the sander to the power source and make
note of the reading on the digital display. Then
manually lower the table an additional 0.020" to
0.030". This is how much lower the Model W1756
outfeed pressure roller or Model W1757 rear sanding
drum outfeed pressure roller should be set when
compared to the height of the Model W1756 infeed
roller or Model W1757 front sanding drum pressure
rollers.
9. DISCONNECT THE SANDER FROM THE POWER SOURCE!
10. Loosen the roller lock nuts on the Model W1756
outfeed pressure roller (
Figure 44) or Model W1757
rear sanding drum outfeed pressure roller (
Figure
45). Turn the adjustment bolts to lower the pressure
roller until it just touches the board.
Note: DO NOT continue to lower the roller beyond
that point.
11. Tighten the roller lock nuts and recheck your
settings.
Note: Variables such as feed rate, depth of the
cut, and the type of sanding belt can play a
big part in determining the proper amount of
downward pressure exerted by the rollers. Some
experimentation may be necessary to achieve the
desired results. However, under no circumstances
should the pressure rollers be set even, or higher
than, the sanding roller, because this can invite
kickback.
