CHANGING FEED SPEED
The conveyor speed ranges from 3 to 20 FPM (Feet Per
minute).
The feed speed adjustment knob,
, is located on the
control box, on the right hand side of the machine.
-
Turn the knob clockwise,
, to increase the feed
rate.
-
Turn the knob counter-clockwise,
, to decrease
the feed rate.
As a general guideline, more aggressive sanding using lower grits or sanding wider boards should be done at slo-
wer speeds and sanding using higher grits or sanding narrow boards can be done at higher speeds.
Given that sanding in successive grits is done in a single pass, results can vary widely depending on a variety of fac-
tors. Experiment with feed speeds based on the workpiece material, board width, depth of sanding, grit selection as
well as required finish results.

For optimal results, the rear drum,
, should be set fra-
ctionally lower than the front drum,
, by the depth of
the grit of the paper on the front drum,
.
-
The front drum his factory set parallel with the con-
veyor table and needs no further adjustments.
-
The rear drum is micro-ajustable. It can be slightly
raised or lowered at each end and must be kept
parallel to the table.
ADJUSTING THE HEIGHT OF THE REAR DRUM
To set the rear drum to the correct height proceed as follows:
1.
Place two gauge blocks (not included) on the
conveyor belt, positioned one under each end of
the front drum (with the sanding belt installed on).
(Fig. 4)
Note: To achieve parallelism with the front drum, any
gauge blocks that are used (whether purchased or
shop made) must be a matching set and must both
be at the same height.
2.
Raise the table until the gauge blocks barely
touch the drum.
