level to slightly lower on the outboard end. This will
prevent any ridges from developing in the stock.
Always check this on a piece of scrap wood, as follows,
before sanding the work piece.
1. Run a piece of scrap wood approximately 150mm
wide by 700mm to 1000mm long through the
sander sideways so that end of board extends
past outboard side of drum.
2. Without changing drum height, rotate board 180°
and sand the same side.
3. If a ridge is visible where the drum overlaps, lower
table at outboard end slightly by turning knob (C,
Figure 8-3).
4. Repeat this process until the ridge is eliminated
and entire board is sanded.
Note: When sanding narrow stock (less than 406mm),
return conveyor table to parallel position. Turn knob
opposite direction until lock nut (D, Figure 8-3) is
contacted. The lock nut provides a positive stop for
table parallelism.

8.5 Tension roller adjustment

The infeed and outfeed rollers are tensioned to
provide downward pressure on the workpiece to
prevent slippage on the feed conveyor. Tension rollers
have been set by the manufacturer, but should be
inspected and may require adjustment as the sander
receives use.
Improperly adjusted
rollers (i.e. those set too high, rendering them non-
functional) could allow kickback of pieces being
sanded.
You can increase or decrease tension roller pressure
by turning the screws on the tension roller brackets
(Figure 8-4).
Figure 8-4: tension adjustment screws
Too much tension roller pressure can result in a
"snipe" mark, which is a visible line running across the
width of the board and located approximately 60mm
from end of board.
If snipe occurs on the leading end of board, adjust
outfeed tension roller. If the snipe occurs on trailing
end of board, adjust infeed tension roller.

9.0 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.

9.1 Basic Operating Procedure

1. Establish depth of cut.
2. Start dust collection system.
3. Turn on the power switch
4. Start sanding drum.
5. Start conveyor and select feed rate.
6. 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.
conveyor table as it begins feeding, causing pinching
hazard. Keep fingers away.
comes to a complete stop.
9.2 Drum & belt motor operation
1. Connect power supply to machine.
2. Turn on main power switch by firmly pressing
tension
switch (A, Figure 9-1)
3. Turn on the rocker switch (B, Figure 9-1) to start
drum motor.
4. Rotate conveyor speed dial (C, Figure 9-1)
clockwise to start and increase speed of conveyor.

9.3 Setting depth of cut

Adjusting the drum sander for proper contact between
abrasive and stock determines the depth of cut. The
depth of cut is controlled by the height adjustment
handle.
