Operation
Before using your drum sander, review the
previous pages in this manual on initial set-up and
adjustment. In this section, you will learn how to
operate the machine. Note that connecting the
machine to an adequate dust collection system is
necessary before operating the unit.
Do not start drum while it is in contact with
workpiece!
Do not place fingers beneath workpiece where
it contacts the conveyor belt!
Basic operating procedure
1. Set depth of cut for front drum.
2. Set depth of cut for rear drum (slightly lower
than front drum if using finer grit).
3. Start dust collection system.
4. Start drums.
5. Start conveyor and select feed rate.
6. Feed stock through machine.
To feed stock through the sander, rest and hold

drums. Once the stock is halfway through,
reposition yourself to the outfeed side of the
machine to receive and control the board as it
exits.
