Drum Sander Assembly
Note: For initial stand assembly secure all bolts nger tight. This will allow
for easier levelling after the sanding unit is installed on the stand. The
holes in the legs are spaced so that the short and long top braces will only
line up from one face of each leg.
1. Secure two legs to the outside of each of the two short top cross braces
using the supplied carriage bolts and ange nuts.
2. Secure the two long top rails inside of the legs and on top of the short
rails.
3. Note: Long rail on top of short rail and both rails inside of legs.

4. Connect the second leg sub-assembly to the top long rails.
5. Attach the lower cross braces to the legs. The longer cross braces
should sit on top of the short ones.
6. Attach a levelling foot to the bottom of each leg (not required if installing
optional caster set).
Note: After nal assembly and sander installation, adjust the nuts on the
threads as needed to level the stand.
IInstalling Drum Sander
1. There will be a small container of hardware included with your sander.
This container will include everything you need to set up your sander.
2. Open box 1 that contains the main sanding unit. Remove the cardboard
liner. Open the plastic bag enclosing the sanding unit.
3. Cut each corner of BOX 1 to fold sides at, providing access to sanding
unit.
4. With one or two helpers, place the sanding unit on stand or bench (lift
points marked).
5. Remove the two wooden packing plates from bottom of the sanding unit
using the enclosed wrench and keep wrench for future adjustments.
NOTE: These bolts that you just removed from the packing plates will
work as your bolts for attaching the sander or as extra bolts for future
replacement.

-6-www.igmtools.com
NOTE: Leave the silver plate, which is near the fast lever and
under the motor, in place when removing bolts.
10. Open box 2 and remove conveyor from packaging and place on
sanding unit. The conveyor motor should be nearest to the main motor
and depth gauge.
NOTE: The fast lever should be in the upright position for installation of
the sanding unit. The fast lever raises the inboard (right) side of conveyor
up. Do not ever tighten the bolts all the way down. The fast lever should
always be able to be moved back and forth between and up/down
position. The bolts should be tightened, but not so tight that the fast lever
doesn’t move. The lever should be able to move from the down to up
position easily.
11. Install lock washer and at washer onto two socket heads (or hex
head bolts) and install into ange of conveyor bed on inboard (right)
(motor side). Keep support plate in place on inboard (right) side and make
sure the fast lever is positioned up.
12. Install two lock washers and two at washers on the studs on outboard
(left) side of the conveyor belt, then tighten all nuts and bolts with wrench.
NOTE: Do not completely tighten bolts with fast lever. See note above.
6. Install knob to height adjustment handle. First, nger tighten nut to
knob. Thread stud from knob into hand wheel and tighten nut against hand
wheel.
7.Turn the handle and raise sanding head to higher position to remove
packing block from under carriage arm.
8. To prepare the unit for the installation of the conveyor belt, rst remove
the 2 bolts on the outboard (left) side of the conveyor belt.
9. Next remove the 2 bolts on the inboard (right) side of the conveyor belt.

-7-www.igmtools.com
13. Plug the short power cord that is attached to the motor into the outlet
on the control box. This cord will provide switched power for the motor
when the machine is plugged into the power source.
14. Check your power supply to make sure that it is adequate (230 V, 1Ph
required) but do not plug the machine into the power supply until it is fully
set-up.
6. Setting and Adjustment
Your sander should now be in place and ready for the nal set-up. The
sander was adjusted and aligned at the factory. However simple alignment
checks will ensure that everything is in perfect order.
Problems can be avoided if these essential checks and set-up procedures
are performed prior to operation.
6.1 Setting the Drum Sander
Checking Drum Alignment
UNPLUG THE MACHINE FROM THE POWER SOURCE!
During initial setup only. Checking the alignment is necessary to make
sure that the drum is parallel.
Before checking the drum alignment make sure that the fast lever between
the conveyor motor and the machine is in the up position
The conveyor table bolts on the inboard side should not be so tight that
the fast lever does not rotate.
1. Remove the abrasive on the drum. Removing the abrasive is necessary
to make sure that the adjustment is as accurate as possible and the
texture on the abrasive will make the adjustment imprecise.
2. Locate the height adjustment handle for raising and lowering the
sanding head.
NOTE: The height adjustment handle controls the drum height. Turning
the handle raises or lowers the sanding head. One revolution of the
handle raises or lowers the head by 1.4 mm.
3. Use a at, uniform piece of wood as a thickness gauge. Insert it
between the conveyor belt and the drum on the inboard (right) side of the
machine.
The tension rollers are set just below the drum enough so that items
cannot pass easily underneath. Use the height adjustment handle as
necessary to ensure that the piece of wood makes contact with the drum.
4. After you place the piece of wood between the conveyor belt and the
drum, rotate the height adjustment handle up one full turn. After the height
has been adjusted the wood piece may be removed.
NOTE: You have to repeat these steps on the outboard (left) side of the
machine using the same procedure. As you check look to make sure that the
drum is parallel. A simple visual check that the drum is parallel is su󰀩cient.

-8-www.igmtools.com
If the drum is not parallel, loosen the 4 socket head screws A (these screws
are along the outboard (left) side of the conveyor belt) and raise or lower the
conveyor with the adjustment nut B to achieve parallel alignment. Then
tighten the four socket head screws.
To achieve parallel alignment on the inboard (right) side of the machine,
repeat steps 3 and 4, then adjust the alignment if needed by loosening the 4
socket head screws located along the outboard (left) side of the conveyor and
turning the height adjustment nut of the conveyor.
Connecting Dust Collection
Dust collection is necessary for the drum sander. The sander comes
equipped with a 100 mm (4”) diameter dust exhaust port at the top of
the cover. Make sure that the minimum dust requirements are su󰀩cient.
To attach to your collection system, install 100 mm (4”) hose from your
collector. The minimum recommended dust collector capacities is 1000
m³/h. For best results, follow the recommendations of the manufacturer
of your dust collector. When connecting dust collector straight pipe is
preferred because it is the least restrictive for airow. If straight pipe is not
possible Y’s and elbows are preferred because they are less restrictive to
airow than T’s.
Note: Some applications will require more dust collection than the
recommended minimum.
Power and Electrical Safety
11. Make sure that your power supply is adequate (230 V, circuit breaker
16 A, rating C (16/1/C))). After the dust collection system is in place and
the drum alignment is checked your machine is ready to be powered up
and operated.

6.2 Installing and Wrapping Abrasives
Accurate attachment of the abrasive to the drum is critical to achieving
the machine top performance. Abrasive strips do not have to be pre-
measured. The end of the roll is rst tapered and attached to the outboard
(left) side of the drum. Then the strip is wrapped around the drum. The
second taper is made for attachment to the inboard (right) side of the
drum.
Note: Pre-cut abrasives have been factory tapered to the specic width of
your drum. If you are cutting your own abrasive, use the wrap that came
on the drum as a template (abrasive side up).
Installing and Wrapping Abrasives (continued)
UNPLUG THE MACHINE FROM THE POWER SOURCE!
1. Mark and cut a taper at one end of the roll as shown below. Because
the tapered end should use most of the left (outboard) slot width, its end
must be trimmed. Start on the left (outboard) side of the drum. Pinch or
squeeze the clip lever on the left (outboard) side of the drum. 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 wrap end
in the fastener.
2. Wind the abrasive around the drum, being careful not to overlap the
windings. The tapered cut of the wrap 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 abrasive with your right hand. Successive
windings of the wrap should be ush with previous windings without any
overlap.
3. Squeeze the clip lever to open the clip and pull the take-up lever to the
top. Insert the tapered end through the slot in the inboard (right) end of
the drum.
4. The take-up fastener is designed to automatically take up any slack
caused by stretching of the abrasive wrap. The abrasive wrap 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 wrap.
If this occurs, it will be necessary to reset the take-up lever by raising it,
pushing the wrap end into the slot, and then releasing the clip lever.
Note: The drum was removed to show the inboard (right) take-up
fastener.
Drum width: 482,5 mm (19“)

NOTE: Take notice that for detail only the drum was removed to show the
inboard (right) take-up fastener.
7. Machine Operation
Proper Abrasive Position
Position the abrasive in the slot with su󰀩cient room between the inside
of the slot and the tapered end of the wrap to allow it to be pulled into the
drum as needed. If enough space is not left between the wrap and the
inside of the slot the take-up fastener will not operate properly.
Abrasive Tension Adjustment
The abrasive wrap may stretch enough to allow the take-up lever to reach
its lowest position. If this occurs, then the abrasive is no longer tensioned.
To x this reset the take-up lever by raising it. Push the abrasive into the
slot and then release the clip lever.
Maximizing Abrasive Longevity
We recommend a sandpaper cleaning stick to remove deposits and help
extend the life of the abrasive.
1. To use the cleaning stick, operate the sanding drum with the dust cover
open and dust collection on.
2. Hold the cleaning stick against the rotating drum and move it along the
drum surface.
3. Use a brush to remove any cleaning stick remnants before resuming
operation.
ALWAYS WEAR EYE PROTECTION WHILE PERFORMING ABRASIVE
CLEANING. TAKE ALL PRECAUTIONS TO AVOID ANY CONTACT WITH
HANDS OR CLOTHING.
OPERATING THE SANDER
Your sander will be able to perform an innite variety of sanding projects
all designed to your specications. With some time and experimentation
the proper setting and technique for each job will become apparent.
DRUM DEPTH OF CUT
Determining the depth of cut is the most important operating procedure
decision. It may take some experimentation to determine the proper depth
of cut. The crucial variables to keep in mind are abrasive grit, type of
wood, project type, and conveyor feed rate. We recommend practicing on
a scrap of wood prior to sanding a project.
Depth Scale Operation
The depth scale (see opposite picture) measures the distance between
the conveyor table and the bottom of the sanding drum. The sanding head
must be parallel to the conveyor bed surface.
1. To calibrate the depth scale, loosen the two screws holding the scale.
Lower the drum (with abrasive installed) until the drum touches the
conveyor belt.
2. 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 (see opposite
picture). This o󰀨ers 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.
1. To operate, turn ON and select standard inch “in” or metric millimeter
“mm”.
2. Lower drum, with abrasive installed, until it touches the conveyor belt.
Press “zero” button to calibrate.
Using Thickness Gauge
Another method to set depth of cut is to use the thickness gauge attached
to the inboard (right) side of the sander (see opposite picture). The gauge
must be adjusted to the same height as the abrasive in use.
1. Place a at piece of scrap stock under the drum with the abrasive in
place. Lower the durm until the abrasive lightly touches the scrap piece of
stock.
2. Without changing the height, place the scrap stock under the thickness
gauge. Adjust the bottom of the gauge by loosening the large nut and
rotating the gauge up or down until it lightly touches the scrap piece of
stock.
3. Tighten the large nut. Now the stock can be placed under the thickness
gauge and the drum lowered until the gauge lightly touches the stock to be
sanded. By using this method the stock does not need to be carried under
the drum to set depth of cut.
A good rule of thumb when sanding is to place the stock under the drum
and lower the sanding head until the stock is in contact with the drum but
the drum can still be rotated by hand. Normally as the depth of cut is
adjusted the handle will be rotated no more than a third of a turn at any
time. INTELLISAND will help with this process.

Button Reference and Use
It is helpful to familiarize these buttons and their purpose with the Wixey
DRO
Calibration
There are three typical variations of calibration. The rst variation (Type 1)
is for the DRO to show the sanded thickness of
the material. The second variation (Type 2) is to show how much stock is
being removed with each pass of the sander.
Another method (Type 3) to show the amount of material being removed
per pass without recalibrating the Type 1 setting.
Type 1 Calibration ABS:
Calibration for the DRO to show sanded thickness (Type 1). Calibration is
quick and easy and requires no extra measuring
device. Make sure the machine is turned OFF and power is disconnected!
1. Wrap the sanding drum with the desired grit abrasive.
2. Lower the sanding drum until it lightly touches the conveyor belt.
3. Turn “ON” the DRO.
4. Hold the “CAL” button 3 seconds until “0.00” appears.
Type 2 Calibration ABS:
Calibration for the DRO to show stock removed per sanding pass (Type
2). Calibration is quick and easy and requires no
extra measuring device. Make sure the machine is turned OFF and power
is disconnected after the rst step!
1. Sand a test piece of stock until it is at and uniform on both sides.
2. Turn the Sander OFF and disconnect power to sander.
3. Position the sanding drum (with abrasive still wrapped on drum) on the
test piece until the drum is lightly touching the test
piece.
4. Press and hold the “CAL” button for 3 seconds until “0.00” appears.
Type 3 Calibration INC:
This method allows saving the original calibration from Type 1 and
conrming the amount of material being removed per
pass.
1. Make one pass sanding your stock. Without changing the drum height
press the “ABS/INC” button to read “0.00”. This

-11-www.igmtools.com
changes the readout from “ABS” to “INC” and zero’s the readout on top of
the just sanded piece. Now the readout will show
the amount of stock removed per sanded pass in “INC” mode.
2. To change back to the original (Type 1) calibration press the “ABS/INC”
button to change back to “ABS” mode.
NOTE: When changing the abrasive wrap to a di󰀨erent grit the DRO must
be recalibrated for the change of drum
diameter with the new grit abrasive!
NOTE: When setting the depth of cut, never exceed the thickness of the
grit for stock removal.
CONVEYOR AND SPEED RATE
After the depth of cut has been determined, selecting the proper feed rate
is essential. For nish sanding the best nish is usually achieved with a
slow to moderate feed rate. Faster feed rates can be used as long as the
machine is not over-stressed.
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 best to make another sanding pass
without changing the thickness setting and sand again
Note: INTELLISAND will automatically adjust the conveyor feed rate if
an excess load is detected. This prevents excessive gouging, reduces
the risk of burning and protects the machine from overload or stalling.
The red light by the adjustment knob will come on when INTELLISAND is
operating. When the load is decreased, INTELLISAND will automatically
increase the feed rate to the pre-selected speed.
Stock Feeding Operation
Rest and hold the stock to be sanded on the conveyor table. Allow the
conveyor to carry the stock into the drum. Once the stock is halfway
through, reposition yourself to the outfeed side of the machine to control
the stock as it exits the unit.
Stock Feeding Maximum Performance
The versatility of this drum sander allows it to be used for a wide range of
tasks. Learning to use the multiple controls to make adjustments will allow
you to ne tune the machine for maximum results.
• Sanding stock wider than the drum
When sanding stock wider than the drum the fast lever will be very useful
(see picture). Wide stock requires extra space between the drum and the
conveyor on the outboard (left) edge. The extra space prevents ridge lines
from developing along the part that extends beyond the drum.
Adjusting the fast lever approximately half-way between the full upright
and full downright position allows for easy alteration of the drum position
in relationship to the conveyor without changing the initial drum alignment.
It is a good idea to test a scrap piece of stock prior to sanding. If a line or
ridge is still visible after adjusting the fast lever additional adjustments can
be made to the drum alignment. After sanding stock wider than the drum
the fast lever should be adjusted back to the original position. The fast
lever should be put into the up position.
Note: The fast lever raises the inboard (right) side of the table .003. Never
tighten the bolts all the way down. The fast lever should always be able to
be moved back and forth between and up/down position. The bolts
should be tightened, but not so tight that the fast lever doesn’t move.
• Sanding multiple pieces simultaneously
When sanding multiple pieces at once, make sure to stagger the pieces
across the width of the conveyor belt. This position provides better contact
with the tension rollers. It is best to only process pieces that are all of a
similar thickness. If there is a thickness di󰀨erence, the thinner pieces may
not come in contact with the tension rollers and may slip on the conveyor
belt.
• Sanding Imperfect or Tall Stock
To avoid bodily injury, take special care when sanding stock that is twisted,
bowed or otherwise varied 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 stand, assistance from another person, or hand pressure
on the stock to minimize potentially hazardous situations. Special
attention is needed as the stock exits the machine. Special attention is
needed as the stock exits the machine.
• Stock Feeding Position and Angle
Positioning the stock at an angle will allow the most e󰀨ective stock
removal and least loading on the abrasives. Feeding stock straight
through yields the widest sanding capacity and least noticeable scratch
pattern. Some pieces because of their dimensions will need to be fed into
the sander at a 90-degree angle (perpendicular to the drum). However,
even a slight o󰀨set angle of the stock can provide for more e󰀨ective
sanding. Final pass sanding should be done while following the grain
pattern.
TENSION ROLLER PRESSURE
The tension roller pressure is factory set and should be adequate.
However, the pressure of each roller can be adjusted as needed.
To increase the tension, turn the tension adjusting screw clockwise 1/4
revolution at a time. To decrease tension, turn the adjusting screw counter
clockwise 1/4 revolution at a time.
Note: Too little pressure can result in slippage of stock on conveyor belt or
kick-back Too much tension can cause snipe when drum sanding.
TENSION ROLLER CONTACT ADJUSTMENT
The tension rollers are factory set for the most versatile use.
1. If necessary, to adjust tension roller contact, loosen the four socket
head screws holding the tension roller brackets (two per side; front and
back – shown in picture).
2. Have abrasive wrapped on drum.
3. With machine unplugged, lower sanding drum until it rests on conveyor
belt.
4. Raise drum 2 to 3 revolutions.
5. Tighten the four socket head screws (two per side; front and back).
6. Raise drum up, o󰀨 of the conveyor belt.
7. Set drum for proper sanding height and process stock.
CONVEYOR BELT TENSION
Insu󰀩cient belt tension will cause slippage of conveyor belt on the drive
roller. The conveyor belt is too loose if it can be stopped by placing your
hand directly on the conveyor belt.
Excessive belt tension can result in bent rollers, premature wearing of the
bronze bushings or conveyor belt.
To adjust the conveyor belt, rst adjust the take-up screw nut on both
sides of the conveyor to obtain approximately equal tension on both sides.

4. Remove the two nuts and washers from outboard (left) side. Lift the
conveyor and remove it from the sander. Set conveyor on motor side.
Avoid tearing the belt on any edges underneath the conveyor bed during
removal. Reverse the procedure for re-installation.
Cleaning the Sander
The sander may need to be cleaned more frequently depending upon
frequency of use. The drum and the conveyor belt need to be clean.
Allowing excess build-up of dust and debris can adversely a󰀨ect
performance and increase the likelihood of slippage on the conveyor belt.
Sweep the conveyor belt clean after all operations. When cleaning dust
from the drum leave the dust collection system on.

CONVEYOR BELT TRACKING
Belt tracking adjustments are made while the conveyor belt is
running.
After the proper belt tension is obtained, turn the conveyor 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 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 does not a󰀨ect the belt tension.
Note: Adjust the take-up screw nuts only 1/4 turn at a time. Allow
the belt to react to the adjustments before proceeding further. Avoid
over-adjustments.
8. Maintenance
Monthly Maintenance
• Lubricate conveyor bushings and check for wear.
• Lubricate with a dry lubricant spray all of the moving parts.
• Clean dust from conveyor belt.
• Check all set screws for tightness.
• Clean drum and abrasives if necessary.
Replacing Conveyor Belt
To replace the conveyor belt, the conveyor assembly must be
removed from the machine.
Unplug the machine from the power source!
1. Raise the drum carriage to its highest position. Unplug main drive
motor from receptacle on the machine.
2. Loosen the conveyor take-up screws to relieve belt tension and
slide the drive roller fully inward.
3. Remove the two hex bolts on the inboard (right) side that attach
the conveyor assembly to the base.
