W1756/W1757 43" Wide-Belt Sander
SERVICE
Pressure Rollers
To adjust the pressure rollers, do these steps:
1. DISCONNECT THE SANDER FROM THE POWER SOURCE!
2. Plane a 6' long 2x4 to a uniform thickness and cut
it in half. Place one board along the length of the
feed belt on the right-hand side and place the other
board on the left-hand side.
3. With the sanding belt tensioned (Figure 41), move
the sanding rollers by hand and
manually raise the
table until you hear the sandpaper just contact the
surface of the wood. DO NOT continue to raise the
table beyond that point.
4. Connect the sander to the power source and make
note of the reading on the digital display. Then
manually lower the table 0.020" to 0.030". This is
how much lower the W1756 infeed pressure roller
and W1757 front sanding drum pressure rollers
should be set when compared to the sanding surface
of the sanding roller.
5. DISCONNECT THE SANDER FROM THE POWER SOURCE!
6. Model W1756: Loosen the roller lock nuts (Figure
42) on both ends of the infeed pressure roller.
Turn the adjustment bolts (
Figure 42) to lower
the infeed pressure roller until it just touches the
board. Tighten the roller lock nuts and recheck your
setting.
Note: DO NOT continue to lower the roller beyond
that point.
NOTICE
The pressure rollers has been adjusted
at the factory and should require
no further attention. However, we
recommend verifying that they are
parallel with each other, the sanding
drum, and the feed belt table surface.
