Selecting the proper feed rate is essential to proper
nish sanding. For nish sanding the best nish is
usually achieved with a slow to moderate feed rate,
after the proper depth of cut has been determined.
is allows for the most revolutions of the drum per
inch of sanding. When abrasive planning, faster feed
rates can be used as long as the machine is not over
stressed. Note, angling stock (Fig. 13) as it is sanded
will allow the most eective stock removal and
least loading of the abrasives. Feeding stock straight
through yields the widest sanding capacity and least
noticeable scratch pattern.
Please note; INTELLISAND will automatically adjust
the conveyor feed rate if an excess load is detected. is
prevents excessive gouging, reduces the risk of burning
and it protects the machine from overload or stalling.
e red light by the adjustment knob will come on when
INTELLISAND is operating. (Fig. 11 a) When the
load is decreased, INTELLISAND will automatically
increase the feed rate to the pre-selected speed.
When nish sanding with grits ner than 80, the best
nish can usually be obtained if INTELLISAND does
not engage. If INTELLISAND does slow the conveyor
when nish sanding, it is usually best to make another
sanding pass without changing the thickness setting and
sanding again.

Determining the depth of cut is the most
IMPORTANT set-up procedure before operating
a drum sander. It may take some experimentation to
determine the proper depth of cut, given the variables
of abrasive grit, type of wood, and conveyor feed rate.
Practicing on scrap before sanding a project can be
benecial.
A good rule-of-thumb when sanding is to place the
workpiece under the drum and lower the sanding head
until the workpiece contacts the drum but the drum can
still be rotated by hand. When making successive passes,
lower the sanding head no more than the thickness of
the grit abrasive, I.e. 1/8-1/16 of a turn for 80 grit and
less for ner grits. Note: one revolution of the height
adjustment handle moves the sanding head 1/16”.

e depth gauge (see Fig. 5) measures the distance
between the conveyor table and the bottom of the
sanding drum. e sanding head must be parallel
to the conveyor bed surface. To calibrate the depth
gauge, loosen the two screws holding the scale. Lower
the brush (with abrasive installed) until the head
touches the conveyor belt. Slide the scale to align
with the pointer at the “0” mark. Tighten the two
screws holding the scale. An optional DRO (digital
read out) for depth is available. Fig. 12. is oers the
most precise reading of sanded thickness and allows
for accurate repeatability of a thickness. Great when
making parts that must be an exact thickness or when
matching a thickness.
To operate, turn ON and select standard inch “in” or
metric millimeter “mm”. Lower drum, with abrasive
installed, until it touches the conveyor belt. Press
