8.0 Operations
Before using your drum sander, review the previous
sections on initial set-up and adjustment. Before
operating, make sure an abrasive strip is mounted
and a proper dust collection system is connected.
8.1 Basic Operating Procedure
1. Establish depth of cut.
2. Start dust collection system.
3. Start sanding drum.
4. Start conveyor and select feed rate.
5. Feed stock through machine.
To feed stock through the sander, rest and hold
board to be sanded on conveyor belt, allowing
conveyor belt to carry board into drum. Once stock
is halfway through, reposition yourself to outfeed
side of machine to receive and control board as it
exits.

8.3 Drum motor operation
1. Connect power supply to machine. – Display
remains dark.
2. Turn on main power switch (A). – Display will
illuminate. Racetrack (G) may flash
continuously, indicating that emergency stop is
still engaged.
3. Rotate emergency stop (D) clockwise to

Note: If drum motor does not start, make sure
conveyor speed dial (C) is set to OFF.
5. Load indicator (H) may illuminate. – When
motor is running without load, one bar may
illuminate. More bars are illuminated as load
increases.
6. Turn off drum motor switch (B). – “ON” will go
dark. Circle (J) will continue running for 5
seconds while drum slows to a stop. Then circle
(J) will stop running.
Do not open drum hood
until drum comes to a complete stop.
8.4 Feed Logic activation
If load on the sanding drum becomes excessive and
motor is overloaded or exceeds specified current,
“FEED LOGIC” (I) flashes and “ON” (I) lights up.
Conveyor will be automatically slowed to highest
efficient speed.
8.5 Conveyor motor operation
Rotate conveyor speed dial (C, Figure 15) clockwise
to start and increase speed of conveyor. –
Racetrack (G) will illuminate and run. Conveyor
speed will show inside racetrack.
IMPORTANT: If sander is shut off or E-stop is
engaged, conveyor speed dial must be returned to
OFF position in order to restart sander.
8.6 Unit conversion
Toggle unit selector button (E) to select imperial or
metric units. Units for drum height and conveyor
speed will change accordingly on the display. When
power is turned off, units default to imperial.
8.7 Drum height setting
Lower drum until it just contacts workpiece, then
push zero depth reset button (F, Figure 16) to zero
the setting of drum height from workpiece. The
handwheel is then used to lower the drum in exact
increments for each pass, by viewing the depth on
the control display (K).
