re 27
) keeps the
machine from being overloaded during sanding
operati
ons.

As a general rule, always start with a shallow
sanding depth and carefully increase the sand-
ing depth.
Keep the amp load in the green range
during operation. Generally, the normal depth
of cut is no more than
1
⁄
64
" or 0.016" for a 36
1
/
2
"
wide board using coarse sandpaper.
DO NOT
work your machine in the red zone as shown on
the Amperage Load Chart. If operated in the red
zone, the motor will lose RPM, the start capacitor
will energize, and capacitor or motor damage will
occur.
Amp load is directly affected by many factors such
as feed rate, depth of cut, wood type, sandpaper
grit, and workpiece width.

Sanding
To sand a workpiece:
1. Adjust the table height according to the
instructions in
Depth of Cut on Page 26.
2. Start the dust collector, the drum motor, and
the feed motor.
3. Feed the workpiece through the sander while
standing to the side and monitor the amp
meter; if it approaches the maximum amp
load, lower the conveyor table.
4. Run wide stock through two or three times
without adjusting the table height. Turn the
stock 180° between passes to ensure an even
cut. Do not sand more than one workpiece at
a time side-by-side.
Close all covers and panels before start-
ing the drum sander. Failure to do so could
result in severe personal injury.
DO NOT sand more than one board at a time
side-by-side. Minor variations in thickness
can cause one board to be propelled by the
rapidly spinning sanding drum and ejected
from the machine. NEVER stand directly in
front of the machine. Failure to do so could
result in severe personal injury.
