Your 19-38 Drum sander was adjusted and aligned at the
factory, and it has been carefully packed for shipment.
However, because of possible stress during transit, the
unit should be thoroughly checked before being put
to use. is section covers the preoperational checks
you should make after unpacking and nal assembly.
Unnecessary problems can be avoided if these essential
checks are performed before operating. Likewise,
performing the recommended monthly maintenance
procedures (page 12) will help assure trouble-free service.

Dust collection is necessary for all models. e 19-38 is
equipped with one 4” diameter dust exhaust port at the
top of the cover.
To attach to your collection system, install 4” hose from
your collector. (See Tips For Maximum Performance,
page 10 of this manual.) e minimum recommended
dust collector capacities is 600 cfm. For best results,
follow the recommendations of the manufacturer of your
dust collection equipment. NOTE: Some applications
will require more dust collection than the recommended
minimum CFM.

e drum height is controlled by the height adjustment
handle (Fig.5). Turning the handle raises or lowers the
sanding head. One revolution of the handle raises or
lowers the table 1/16 of an inch.
Before operating height adjustment, be sure the
packing-block is removed. It is located under the
outboard end of the carriage arm (Fig. 4). Raise drum
to remove.
D A
Check alignment when using sanding drum. After
installing sanding drum, remove abrasive from drum.
Using a at piece of wood or aluminum as a thickness
gauge, insert it between the conveyor belt and the
drum on the right (inboard) side of the machine (Fig.
5). Lower the sanding head so the drum just contacts
the thickness gauge. en, holding up the front
tension roller, check both sides of the drum using the
thickness gauge. If the drum is not parallel, loosen
the four socket head cap screws (along the outboard
edge of the conveyor) (Fig. 7) and raise or lower the
conveyor with the 7/16” adjustment nut to achieve
parallel alignment. Tighten the four socket head cap
screws.
C C B T
Conveyor belt tracking adjustments may occasionally
be necessary during break-in and normal operation
to compensate for belt stretching. If adjustments
are necessary, follow the instructions below: Belt
tracking adjustments are made while the conveyor
belt is running. With the conveyor unit on and set at
the fastest speed setting, watch for a tendency of the
conveyor belt to drift to one side of the conveyor. To
adjust the belt tracking, tighten the take-up screw nut
(Fig. 8 & 9) on the side the belt is drifting toward,
and loosen the take-up screw nut on the opposite
side. Adjusting the take-up screw nuts on both sides
of the conveyor allows belt tracking adjustments to
be made without aecting belt tension. Adjust the
takeup screw nuts only 1/4 turn at a time. en allow
time for the belt to react to the adjustments before
proceeding further. Try to avoid over-adjustments.
NOTE: Make sure wrench is below surface when
brushing or sanding.

Before using your Sander, review the previous pages in
this manual on initial set-up and adjustment. In this
section, you will learn how to operate the machine.
Note that connecting the machine to an adequate
dust collection system is necessary before operating
the unit.
e SM oers considerable control and
versatility through variable feed rates and abrasive
selections. Experiment with both to nd the proper
sander performance for a given application.
B O P
After you have connected the machine to a dust
collection system, you are ready to begin to use the
SM. e basic operating procedure for the
SM models is as follows (Fig. 10):
1. Set depth of cut (page 10).
2. Start sanding drum and select slow brush
speed (page 8).
3. Start conveyor and select feed rate (page 10)
4. Start dust collector system.
5. Feed stock through unit.
To feed stock through the SM, rest and
hold the stock to be sanded on the conveyor table,
allowing the conveyor belt to carry the stock into the
drum. Once the stock is halfway through, reposition
yourself to the outfeed side of the machine to receive
and control the stock as it exits the unit.
T R A
Spring loaded infeed and outfeed Tension Rollers (Fig.
11 & page 22) are provided to maintain downward
pressure on stock being sanded and to prevent slippage
of the stock on the conveyor. When properly set, the
Tension Rollers should engage or raise up about 1/8”
to accommodate the stock being brushed.
T R P
e tension roller pressure is factory set for most
applications. However, the pressure of each roller can
be adjusted. Caution, too little pressure can result in
slippage of stock on conveyor belt or kick-back. Too
much tension can cause snipe when drum sanding.
To increase tension turn the tension adjusting
screw clockwise ¼ revolution at a time. To decrease
tension turn the adjusting screw counter-clockwise ¼

T R P
e tension rollers are factory set for the most versatile use.
Flat Surfaced Stock: If necessary to adjust tension
roller contact, loosen the four socket head screws
holding the tension roller brackets (Fig. 11 & 11A).
Have abrasive wrapped on drum. With machine
unplugged, lower sanding drum until it rests on
conveyor belt. Raise drum 2 to 3 revolutions. Tighten
the four socket head screws. Raise drum up, o of

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.
S D D C
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”.
D G O
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

For best results, perform the following recommended
maintenance procedures on a monthly basis:
• Lubricate conveyor bushings and check for
wear.
• Lubricate all moving parts, such as threaded
rods and washers
• Clean dust from the conveyor belt.
• Blow dust from the motors.
• Check all set screws for tightness.
• Clean drum and abrasives, if applicable.
T F M P
e versatility designed into the 19-38 Drum Sander
allows it to be used for a wide-ranging variety of
tasks that will boost the return on your investment.
Learning to use its multiple adjustments and controls
will allow you to ne-tune the machine for maximum
results, regardless of the job to be done. e best
results come from experimenting with dierent
machine adjustments to t the job at hand. Following
is a listing of useful tips which can help you improve
performance of your brush sander.
Dust Collection. When connecting dust collectors,
remember that straight pipe will not restrict airow
as much as exible tubing. Also, Ys and elbows will
restrict airow less than Ts.
Brushing Multiple Pieces At Once. When sanding
multiple pieces simultaneously, make sure to stagger
(step) the pieces across the width of the conveyor belt.
is provides better contact with the tension rollers.
Try to only process multiple pieces of similar thickness.
If there is a thickness dierence, the thinner pieces
can slip on the conveyor belt if they do not contact
the tension rollers. When sanding high or tall stock,
special care is needed to prevent tipping and slilppage.
Sanding Imperfect Stock. To avoid personal injury,
take special care when sanding stock that is twisted,
bowed, or otherwise varies in thickness from end
to end. If possible, support such stock as it is being
sanded to keep it from slipping or tipping. Use
extra roller stands, help from another person, or
hand pressure on the stock, to minimize potentially
hazardous situations.
Stock Feeding Angle. Some pieces, because of their
dimensions, will need to be fed into the machine at a
90° angle (perpendicular to the drum). However, even
a slight oset angle of the stock can provide for more
eective sanding on most stock (Fig. 13).
Keeping the Machine Clean. For best results, make
Fig. 11 Tension rollers adjustment
Fig. 11A Tension roller height and depth gauge adjustment
cleaning the machine a regular shop procedure.
Allowing excess build-up of dust and debris can
adversely aect performance, slippage on the conveyor
belt, and/or the accumulation of material on the brush
which can throw o the center of balance. Leave the
dust collector on when cleaning dust from the drum.
Sweep the conveyor belt after cleaning operations. If
not cleaned, the conveyor belt could allow stock to
slip during operation.
Sanding Stock wider than drum: e “Fast Lever” is
very useful when sanding stock wider than the drum.
Sanding stock wider than the drum may require extra
space between the drum and the conveyor along the
outboard edge. e extra space helps prevent an
overlap line or ridge from developing along the sanded
part when it extends beyond the sanding drum.
e 19-38 sander is equipped with a “Fast Lever”
adjuster mechanism that allows easy changing of
the drum alignment in relationship to the conveyor
without changing the initial drum alignment.
To operate, loosen the two bolts through the ange
of the conveyor on the inboard side (motor side)
of the conveyor bed. Flip “Fast Lever” down (Fig
4B). Tighten the two bolts through the ange of
the conveyor bed. It is a good idea to test a scrap
piece before sanding good stock. If a line or ridge
is still visible after adjusting “Fast Lever” additional
adjustments can be made to the initial drum alignment
(Page 7).
To sand stock narrower than the drum, reverse the
previous steps making sure the “Fast Lever” is in the
UP position (Fig. 4B) and bolts are tight in ange of
conveyor bed on inboard side.

Note: When using Pre-Marked™ or Pre-Cut™
abrasives, not all of the steps below are necessary.
Proper attachment of the abrasive strip to the drum
is critical to achieving top performance from your
SM Tools drum sander. Abrasive strips do not
have to be pre-measured. e end of the roll is rst
tapered and attached to the left (outboard) side of the
drum. en the strip is wrapped around the drum,
and the second taper is made for attachment to the
right (inboard) side of the drum. To attach a strip to
the drum, follow the procedure below.
1. Mark and cut a taper at one end of the roll as
shown in Fig. 16a. Because the tapered end should
use most of the left (outboard) slot width, its end
must be trimmed (Fig. 16B and 16C). Raise the
clip lever on the left (outboard) side of the drum
(Fig. 16D). Insert the tapered end through the slot
and into the fastener so that it uses most of the
width of the slot. Release the clip lever to securely
hold the strip end in the fastener.
2. Wrap the strip around the drum, being careful
not to overlap the windings. e tapered cut of
the strip end should follow the edge of the drum.
Continue to wrap the abrasive in a spiral fashion by
rotating the drum with your left hand and guiding
the strip with your right hand (Fig 16E). Successive
windings of the strip should be ush with previous
windings without any overlap.
3. Mark the trailing end of the strip where it crosses the
right (inboard) end of the drum (Fig. 16F). From
this point, cut a taper as was done with the starting
edge of the strip. (e taper on the remaining roll
can be used as the taper for the starting edge of the
next strip to be cut.)
4. With the trailing edge of the strip properly cut,
rewrap the drum and insert the tapered end
through the slot in the right (inboard) end of the
drum. Insert the tapered end into the inboard take-
up fastener. Pull up on the clip lever to open the
clip, and pull the take-up lever to the top as shown
(Fig. 16G). After inserting the strip end, release the
clip lever by moving your index nger toward the
drum slot. is allows the clip to retain the abrasive
while holding the take-up lever in an “up”position.
5. e take-up fastener is designed to automatically
take up any slack caused by stretching of the
abrasive strip. Important: Position the abrasive
strip in the slot with sufficient room between the
inside of the slot and the tapered end of the strip to
allow it to be pulled into the drum as needed (Fig.
16H). Note that not leaving enough space between
the strip and the inside of the slot will prevent the
take-up fastener from operating properly.
6. e abrasive strip may stretch enough in use to allow
the take-up lever to reach its lowest position so it no
longer is able to maintain tension on the strip (Fig.
16I). If this occurs, it will be necessary to reset the
take-up lever by raising it, pushing the strip end into
the slot, and then releasing the clip lever.
Note: A sandpaper cleaning stick may be used to
remove deposits and help extend sandpaper life. To
use, operate the sanding drum with the dust cover
open. (Caution: For your own safety, always wear eye
protection while performing sandpaper cleaning, and
take all precautions to avoid any contact of hands or
clothing with uncovered drums.) Hold the cleaning
stick against the rotating drum and move it along the
drum surface. It is good procedure to use a shop brush
to remove any cleaning stick crumbs from the drums
before resuming sanding operations.

To replace the conveyor belt, the conveyor assembly
must be removed from the machine. Raise the
drum carriage to its highest position using the
height adjustment handle. Turn o power source to
machine. Unplug main drive motor from receptacle
(in gear motor assembly). Loosen the conveyor take-
up screws (Fig. 9) to relieve belt tension and slide
the driven roller fully inward. Remove the two bolts
(inboard side) that attach the conveyor assembly to
the base (see Fig. 11A & 17). Remove the two nuts
and washers (outboard side) (Fig. 7 & 18). Lift the
conveyor and remove it from the sander. Stand
conveyor on motor side. Avoid tearing the belt on any
edges underneath the conveyor bed during removal.
Reverse the procedure for re-installation. Re-install
the conveyor bed to sander.
Conveyor Belt Tension: To adjust the tension of
the conveyor belt, rst adjust the take-up screw nut
(Fig. 9) on both sides of the conveyor to obtain
approximately equal tension on both sides of the belt
when taut. Insucient belt tension will cause slippage
of conveyor belt on the drive roller during sanding
operation. e conveyor belt is too loose if it can
be stopped by hand pressure applied directly to the
top of the conveyor belt. Excessive belt tension can
result in bent rollers, premature wearing of the bronze
bushings or conveyor belt
Conveyor Belt Tracking: Belt tracking adjustments
are made while the conveyor belt is running. After
the proper belt tension is obtained (see above), turn
the conveyor unit on and set it at the fastest speed
setting. Watch for a tendency of the conveyor belt to
drift to one side of the conveyor. To adjust the belt
tracking, tighten the take-up screw nut (Fig. 9) on the
side the belt is drifting toward, and loosen the take-up
screw nut on the opposite side. Adjusting the take-up
screw nuts on either side of the conveyor allows belt
tracking adjustments to be made without aecting
belt tension. Note: Adjust the take-up screw nuts
only 1/4 turn at a time. en allow time for the belt
to react to the adjustments before proceeding further.
Avoid over-adjustments.
