both adjustment knobs so that the indicator nee-
dles move to the desired setting at the plus (+) end
of the scale. The depth of cut of the rear drum
should be rechecked each time a different grit
combination is used.

Fine-tuning the rear drum settings can help

improve performance. Here is a quick way: Raise
the rear drum so it is higher than the front drum,
with the indicators showing a

-3 setting. Place the

stock to be sanded under the front drum. Then
raise the conveyor table so the front drum
contacts the wood, but still can be rotated by
hand. Sand the piece with the front drum and stop
the machine. Then insert the stock in from the
back so it is under the rear drum only. Lower the
rear drum using the adjustment knobs on each
side. Lower the rear drum until it contacts the
stock but still can be rotated by hand. Use this
setting, and note the readings on the depth
indicators for future reference.

ISENGAGING

RUMS

On dual drum models, either the primary (front) or
rear drum may be disengaged so that the other
drum can be used alone. To use the front

drum as a single-drum sander, disengage the rear
drum by raising it to the -2 setting on the indicators
on both sides. To use the rear drum alone, lower it
to the +4 setting on both sides. In this mode, the
table height adjustment handle is used to
determine the depth of cut, which will be limited
to about 1/32 of an inch before the front drum
starts contacting the work piece.

Selecting the proper feed rate is essential to proper
finish sanding. The variable feed rate control of the
conveyor belt adjusts the load on the machine; it
can be infinitely adjusted for maximum operating
performance. A faster feed rate allows faster sanding
but fewer revolutions of the drums per inch of
sanding. A slower feed rate provides more revolu-
tions of the drum per inch of sanding to allow a
greater depth of cut and smoother sanding.

The Intellisand control (See Fig. 13) continuously

monitors the load on the drum motor and automat-
ically regulates the speed of the conveyor motor to
maintain the highest feed rate without overload. If
the load on the drum motor increases, the
Intellisand control will decrease the conveyor feed
rate and will stop the conveyor under extreme con-
ditions. If the load on the drum decreases, the
Intellisand control will increase the feed rate but
WILL NOT increase it faster than the manual set-
ting on the switch dial.

For abrasive planing and thicknessing, the feed

rate can be set at any speed after adjusting for the
proper depth of cut. If the load on the drum motor
approaches its limit, due to inconsistent stock, the
feed rate will automatically slow down. As the load
on the drum motor decreases, the feed rate will
automatically increase to its original setting.

When finish sanding with grits finer than 80, the

best finish will be achieved if the conveyor does not
change speeds during operation. While the
Intellisand control will slow the feed rate when the
main motor reaches its limit, it is advisable to
operate below the regulation point. When the red
indicator light comes on, the Intellisand control has
detected too great a depth of cut and/or too fast a
feed rate. This change in conveyor speed may leave
a detectable mark on finish surfaces. If a mark is vis-
ible, make adjustments by slowing conveyor and/or
lessening the depth of cut and run the stock
through again.
