Serious injury or death can occur from getting hands trapped between workpiece and conveyor table
and being pulled into machine, or becoming entangled in rotating parts inside machine. Workpieces

thrown by sander can strike nearby operator or bystanders with signi cant force. Long-term

respiratory damage can occur from using sander without proper use of a respirator. To reduce the risk
of these hazards, operator and bystanders MUST completely heed the hazards and warnings below.

SAFETY

Additional Drum Sander Safety

For Machines Mfd. Since 01/24

Placing fingers between
workpiece and conveyor can result in
pinching injuries, or possibly getting
trapped and pulled into sanding area of
machine. DO NOT place fingers under
bottom of workpiece while feeding it into
sander.

Sanding creates large amounts of
fine airborne dust that can lead to eye injury
or serious respiratory illness. Reduce your
risk by always wearing approved eye and
respiratory protection when sanding. Never
operate without adequate dust collection
system in place and running. However, dust
collection is not a substitute for using a
respirator.

An accidental startup while
changing sanding belts or performing
adjustments or maintenance can result
in serious entanglement or abrasion
injuries. Make sure machine is turned OFF,
disconnected from power and air, and all
moving parts are completely stopped before
changing belts, doing adjustments, or
performing maintenance.

Rotating sandpaper can
remove a large amount of flesh quickly.
Keep hands away from rotating sanding
drum(s) during operation. Never touch
moving sandpaper.

Avoiding Entanglement: Tie back long hair,

remove jewelry, and do not wear loose
clothing or gloves. These can easily get
caught in moving parts. Never reach
inside machine or try to clear jammed
workpiece while machine is operating.
Keep all guards in place and secure.

Workpiece Material: This sander is designed to

sand only natural wood products or man­made products made from natural wood
fiber. DO NOT sand any metal products.

Workpiece Inspection: Nails, staples, knots,

or other imperfections in workpiece can
be dislodged and thrown from sander
at high rate of speed into operator or
bystanders, or cause damage to sandpaper
or sander. Never try to sand stock that has
embedded foreign objects or questionable
imperfections.

Kickback: Occurs when a workpiece is ejected

out the front of sander at a high rate of
speed toward operator or bystanders. To
reduce risk of kickback-related injuries,
always stay out of workpiece path, only
feed one board at a time, and always
make sure pressure rollers are properly
adjusted below sanding roller. Never sand
workpieces below minimum specifications
listed in Machine Data Sheet.

No list of safety guidelines can be complete. Every shop environment is different. Always consider
safety first, as it applies to your individual working conditions. Use this and other machinery with
caution and respect. Failure to do so may result in serious personal injury or property damage.

Before installing the machine, consider the
availability and proximity of the required power
supply circuit. If an existing circuit does not meet
the requirements for this machine, a new circuit
must be installed.

To minimize the risk of electrocution, fire,
or equipment damage, installation work and
electrical wiring must be done by a
or qualified service personnel
applicable electrical codes and safety standards.

The full-load current rating is the amperage
a machine draws at 100% of the rated output
power. On machines with multiple motors, this is
the amperage drawn by the largest motor or sum
of all motors and electrical devices that might
operate at one time during normal operations.

The full-load current is not the maximum
amount of amps that the machine will draw. If
the machine is overloaded, it will draw additional
amps beyond the full-load rating.

If the machine is overloaded for a sufficient
length of time, damage, overheating, or fire may
result—especially if connected to an undersized
circuit. To reduce the risk of these hazards,
avoid overloading the machine during operation
and make sure it is connected to a power supply
circuit that meets the requirements in the
following section.

This machine is prewired to operate on a power
supply circuit that has a verified ground and
meets the following requirements:

Note: The circuit requirements in this manual
are for
machine will be running at a time. If this
machine will be connected to a shared circuit
where multiple machines will be running at
the same time, consult a qualified electrician to
ensure the circuit is properly sized.

A power supply circuit includes all electrical
equipment between the main breaker box or fuse
panel in your building and the incoming power
connections inside the machine. This circuit
must be safely sized to handle the full-load
current that may be drawn from the machine for
an extended period of time. (If this machine is
connected to a circuit protected by fuses, use a
time delay fuse marked D.)

This machine must be grounded! In the event
of
grounding provides a path of least resistance
for electric current
electric shock.

Improper connection of the equipment-grounding
wire can result in a risk of electric shock. The
wire with green insulation (with or without
yellow stripes) is the equipment-grounding wire.
If repair or replacement of the power cord or
plug is necessary, do not connect the equipment­grounding wire to a live (current carrying)
terminal.

Check with an electrician or qualified service
personnel if you do not understand these
grounding requirements, or if you are in doubt
about whether the tool is properly grounded.

If you ever notice that a cord or plug is
damaged or worn, disconnect it from power, and
immediately replace it with a new one.

We do not recommend using an extension cord
with this machine. If you must use one, only
use it if absolutely necessary and only on a
temporary basis.

Extension cords cause voltage drop, which may
damage electrical components and shorten motor
life. Voltage drop increases as the extension cord
size gets longer and the gauge size gets smaller
(higher gauge numbers indicate smaller sizes).

Any extension cord used with this machine
must contain a ground wire, match the required
plug and receptacle listed in the

Requirements

OPERATION

Operation Overview

Due to the generic nature of this overview,

To reduce the risk of
serious injury when using
this machine, read and
understand this entire
manual before beginning
any operations.

To complete a typical sanding operation, the
operator does the following:

1. Examines workpiece to verify it is suitable

for sanding and determines which sandpaper
grit size to use.

2. Verifies workpiece has necessary outfeed

clearance and support. If workpiece is overly
long and difficult to handle, operator uses a
roller support stand or an assistant to assist
with feeding.

3. Adjusts table height to approximate

workpiece thickness.

Note: During initial pass with a new

workpiece, operator adjusts table height as
necessary so workpiece only makes light
contact with sanding drums and does not
overload sander.

4. Puts on safety glasses, respirator, and any

other required protective equipment.

5. Starts dust collection system and then drum

sander. Waits for sanding drums to reach
full speed and then sets conveyor speed for
the specific type and finish of workpiece.

Loose hair, clothing, or
jewelry could get caught
in machinery and cause
serious personal injury.
Keep these items away
from moving parts at all
times to reduce this risk.

To reduce risk of eye injury
from flying chips or lung
damage from breathing dust,
always wear safety glasses
and a respirator when
operating this machine.

6. Feeds workpiece into sander by placing front

end on infeed side of conveyor table and
supporting back end until workpiece engages
with pressure rollers. Adjusts conveyor
speed as needed to maintain safe amperage
level.

7. Receives workpiece from outfeed side of

conveyor table.

8. Raises height of conveyor table a small

amount (typically
then repeats the feeding process of workpiece
through sander.

OPERATION

Stock Inspection & Requirements

Some workpieces are not safe to sand, or they
may require further preparation before they can
be safely sanded without increasing risk of injury
to the operator or damaging the sanding belt or
the sander.

Before sanding, inspect all workpieces for the
following:

• Material Type: This machine is intended

for sanding natural and man-made wood
products, and laminate-covered wood
products. This machine is NOT designed
to sand glass, stone, tile, plastics, drywall,
cementious backer board, metal, etc.

Sanding metal objects can increase the

risk of fire. Sanding improper materials
increases the risk of respiratory harm to the
operator and bystanders due to the especially
fine dust inherently created by all types of
sanding operations—even if a dust collector
is used. Additionally, the life of the machine
and sanding belts may be greatly reduced
(or immediately damaged) from sanding
improper materials.

• Foreign Objects: Tramp metal, nails, staples,

dirt, rocks and other foreign objects are
often embedded in wood. While sanding,
these objects can become dislodged and tear
the sanding belt. Always visually inspect
your workpiece for these items. If they can't
be removed, DO NOT sand the workpiece.

• Wet or "Green" Stock: Sanding wood

with a moisture content over 20% causes
unnecessary clogging and wear on the
sanding belt, increases the risk of kickback,
and yields poor results.

• Excessive Warping: Workpieces with

excessive cupping, bowing, or twisting
are dangerous to sand because they are
unstable and often unpredictable when being
sanded. DO NOT use workpieces with these
characteristics!

• Excessive Glue or Finish: Sanding

workpieces with excess glue or finish will
load up the abrasive, reducing its usefulness
and lifespan.

• Minimum Stock Dimensions: DO NOT sand

boards less than 9" long, 2" wide, and
thick to prevent damage to the workpiece
and to reduce the risk of your hands
contacting the abrasive belt (see Figure 14).

OPERATION

For Machines Mfd. Since 01/24

The Model SB1102 allows you to place a different
grit sandpaper on each drum. The front drum
should have a coarser grit than the rear. Usually
this translates into combinations of successive
group types. A common selection for stock that is
planed before being sanded is a 80-100/120-150
grit combination.

The general rule of thumb is to sand a workpiece
with progressively higher grit numbers, with no
one grit increase of more than 50 from one drum
to another. Avoid skipping grits; the larger the
grit increase, the harder it will be to remove the
scratches from the previous grit.

Ultimately, the type of wood you use and your
stage of finish will determine the best grit types
to install on your sander.

Take light passes. Overloading the motor or
pushing the sander to failure weakens the
electrical system. Repeatedly doing so is abuse
to the machine that will cause motor, capacitor,
or circuit breaker damage, which is not covered
under warranty.

• Extend sandpaper life by regularly using a
PRO-STICK® sanding pad (see Page26).

• When sanding workpieces with irregular
surfaces, such as cabinet doors, take very
light sanding passes to prevent gouges. When
the drum moves from sanding a wide surface
to sanding a narrow surface, the load on the
motor will be reduced, and the drum will
speed up, causing a gouge.

• DO NOT edge sand boards. This can cause
boards to kickback, causing serious personal
injury. Edge sanding boards also can cause
damage to the conveyor belt and sandpaper.

• When sanding workpieces with a bow or
crown, place the high point up (prevents the
workpiece from rocking) and take very light
passes.

• Feed the workpiece at an angle to maximize
stock removal and sandpaper effectiveness,
but feed the workpiece straight to reduce
sandpaper grit scratches for the finish
passes.

Sanding Tips

• Replace the sandpaper with a higher grit to
achieve a finer finish.

1

• Raise the table with a maximum of
the height handwheel after each pass until
the workpiece is the desired thickness.

• Reduce snipe when sanding more than one
board of the same thickness by feeding them
into the sander with the front end of the
second board touching the back end of the
first board.

• Feed boards into the sander at different
points on the conveyor to maximize
sandpaper life and prevent uneven conveyor
belt wear.

• DO NOT sand boards less than 9" long, 2"
wide, and
workpiece and the drum sander.

• When removing glue, always use a coarse grit
sand paper and take light passes. This will
reduce the risk of overheating which can plug
the sandpaper and potentially damage the
machine.

Untrained users have an increased risk of seri­ously injuring themselves with this machine.
Do not operate this machine until you have
understood this entire manual and received
proper training.

OPERATION

Sanding

DO NOT sand more than one board at a
time. Minor variations in thickness can
cause one board to be propelled by the rap­idly spinning sanding drum and ejected from

he machine. NEVER stand directly in front

t
of the outfeed area of the machine. Failure
to do so could result in severe personal
injury.

To sand a workpiece:

1. Adjust table height (refer to Setting Depth

of Cut).

2. Make sure dust-collection hoses and

collection system are secured and turned ON
before starting sander.

3. Turn machine ON and feed workpiece

through sander. To reduce likelihood of
injury, retrieve workpiece by standing to
side of machine—not directly behind outfeed
end.

Setting Depth of Cut

The optimum depth of cut will vary based on
the type of wood, feed rate, and sandpaper
grit. Under most sanding conditions, the
depth should not exceed
of the handwheel). Each full turn of the table
height handwheel raises the conveyor table
approximately 0.020". Attempts to remove
too much material can cause jamming, wood
burning, rapid paper wear or tearing, poor
finish, and belt slippage.

To set depth of cut:

1. Using table height handwheel (see

Figure 15), adjust conveyor table until there
is a small gap between workpiece and sanding
drum.

Note: When adjusting the table to sand a

workpiece, lower and then raise the table
to remove backlash from the adjustment
mechanism.

⁄64" (approx. 3⁄4 turn

4. Run wide stock through two or three times

without adjusting table height. Turn stock
180° between passes to ensure an evenly
sanded surface.

Tip: For best sanding results, always sand

with the grain during finish passes.

5. Turn machine OFF.

is the correct height to begin sanding the
workpiece.

OPERATION

For Machines Mfd. Since 01/24

Setting Conveyor Speed

The Conveyor Speed Control dial (see Figure 16)
allows you to set the conveyor speed from 0–10
(0–20 FPM). The correct speed to use depends
on the type of stock you are using (hardwood vs.
softwood) and the stage of finish you are at with
that workpiece.

As a general rule, a slower speed will sand the
surface smoother, but runs the risk of burning
the wood; a faster speed will remove material
faster, but runs the risk of overloading the
motor. Use trial-and-error to determine the best
settings for your specific applications.

To set conveyor speed:

1. Turn Conveyor Speed Control dial (see

Figure 16) to "0," and then turn conveyor
motor ON.

2. Turn Conveyor Speed Control dial

clockwise to increase conveyor speed.

Monitoring Sanding Load

The sanding load meter, shown in Figure 17,
displays the amperage draw of the sanding
drum motor. The number shown increases
when you increase the load on the sanding
drums and decreases when you decrease the
load. Use this meter to avoid overloading your
machine with too heavy of a cut.

IMPORTANT: NEVER exceed 25 amps—this
is the maximum that your machine can safely
handle!

Since various types of stock will react
differently with various loads, use trial-and­error to determine the best settings for your
applications. Always start with a small load
and work your way up. We recommend that
you do not push your machine to its maximum
load; instead, make multiple passes or install a
coarser grit paper.

— If conveyor speed is too high, turn dial

counterclockwise to decrease conveyor
speed.

MAINTENANCE

MAINTENANCE

Maintenance Schedule

Always disconnect
machine from power before
performing maintenance or
serious personal injury may
result.

For optimum performance from your machine,
follow this maintenance schedule and refer to
any specific instructions given in this section.

To minimize your risk of injury and maintain
proper machine operation, shut down the
machine immediately if you ever observe any
of the items below, and fix the problem before
continuing operations:

Note: This maintenance schedule is based on
average daily usage. Adjust the maintenance
schedule to match your usage, to keep your drum
sander running smoothly, and to protect your
investment.

Ongoing

• Worn or damaged sandpaper rolls.

• Loose mounting bolts.

• Any other unsafe condition.

Weekly

• Clean/vacuum dust buildup from underneath
dust hood.

• Clean/vacuum dust buildup from inside
cabinet and off motor.

• Lubricate pillow bearings (Page 28).

Machine Storage

All machinery will develop serious rust problems
and corrosion damage if it is not properly
prepared for storage. If decommissioning this
machine, use the steps in this section to ensure
that it remains in good condition.

To prepare your machine for storage or
decommission it from service:

1. Disconnect all power sources to the machine.

2. Thoroughly clean all unpainted, bare metal

surfaces, then coat them with a light weight
grease or rust preventative. Take care to
ensure these surfaces are completely covered
but that the grease or rust preventative is
kept off of painted surfaces.

Note: If the machine will be out of service for

only a short period of time, use way oil or a
good grade of medium-weight machine oil
(not auto engine oil) in place of the grease or
rust preventative.

3. Loosen or remove belts so they do not become

stretched while the machine is not in use.

4. Completely cover the machine with a tarp

or plastic sheet that will keep out dust and
resist liquid or moisture. If machine will be

Cleaning & Protecting

Cleaning the Model SB1102 is relatively easy.
Vacuum excess wood chips and sawdust, and wipe
off the remaining dust with a dry cloth. If any
resin has built up, use a resin dissolving cleaner
to remove it.

Lubrication

An essential part of lubrication is cleaning the
components before lubricating them. This step
is critical because dust builds up on lubricated
components, which makes them hard to move.
Simply adding more grease to built-up grime
will not result in smooth moving parts. Clean the
components in this section with and oil/grease
solvent cleaner or mineral spirits before applying
lubrication.

The following are the main components that
need to be lubricated:

• Pillow Bearings

• Worm Gear

• Table Elevation Leadscrews, Chain, and
Sprockets

The pillow block bearings require a small amount
of grease every 20 hours of operation to ensure
smooth sanding drum rotation. The four pillow
bearings are lubricated by grease fittings (see
Figure 30). To lubricate the pillow bearings,
remove the grease fitting cap, use a grease gun to
pump a small amount of grease into the fitting,
then re-attach the cap.

Grease Fitting Grease Fitting

Lubricate the bearings sparingly after
about two months of sander operation. The
bearings require very little grease, so avoid
the temptation to over-lubricate.

Adjusting Pressure Rollers

Proper pressure on the workpiece helps avoid
kickback and keeps the workpiece from slipping.
However, as pressure increases on the workpiece,
snipe also increases (snipe is normal with all
brands of drum sanders).

If snipe becomes a problem, you can minimize
it by a combination of reducing pressure and/
or adjusting pressure roller height. However,
you can only minimize it so much before the
workpiece will slip or kick out, causing a hazard
to the operator. If this happens, you have
raised the pressure rollers too high or decreased
pressure too much for them to function as
intended—the pressure rollers MUST properly
adjusted to prevent injury.

Before adjusting pressure roller height, first
make sure that the drums are correctly adjusted.
Refer to Aligning Drums on Page 31.

V-Belt Tension

New V-belts often stretch and loosen up during
the first 16 hours of use. After this period,
they should be inspected and re-tensioned if
necessary. Replace V-belts if you notice fraying,
cracking, glazing, or any other damage. A worn/
damaged belt will not provide optimum power
transfer from the motor to the drums.

The sanding drums are driven by two V-belts.
The belts must have proper tension for optimum
power transfer. However, too much tension may
cause premature bearing failure. Proper tension
is achieved when the belts deflect about
with moderate finger pressure at the midpoint
between the drum pulley and the motor pulleys
(see Figure 48).

Always inspect V-belts for damage or
deterioration when adjusting tension. Should

V-Belt Removal/Replacement

Replace the V-belts if you notice fraying,
cracking, glazing, or any other damage. A worn/
damaged V-belt will not provide optimum power
transmission from the motor to the drums.

V-belt removal and replacement is simply a
matter of raising the motor and loosening the
V-belts until you can roll them off the pulleys,
replacing them with a MATCHED set, then re­tensioning them. Always replace both belts at the
same time with a new matched set.

Pulley Alignment

Pulley alignment is another important factor
in power transmission and belt life. The pulleys
should be parallel to each other and in the same
plane (coplaner) for optimum performance.

Each pulley can be adjusted by loosening the set
screw that secures the pulley to the shaft, sliding
the pulley in/out, and retightening the set screw
to lock the pulley in place.

Belts and pulleys will be hot after operation.
Allow them to cool before handling.

To align pulleys:

1. DISCONNECT MACHINE FROM POWER!

2. Perform Steps 1 –3 of V-Belt Tension on

Touching electrified parts will result in
personal injury including but not limited to
severe burns, electrocution, or death. For
your own safety, disconnect machine from
the power source before servicing electrical
components or performing any wiring tasks!

All connections must be
tight to prevent wires from loosening during
machine operation. Double-check all wires
disconnected or connected during any wiring
task to ensure tight connections.

Using aftermarket parts or
modifying the wiring beyond what is shown
in the diagram may lead to unpredictable
results, including serious injury or fire.

The motor wiring shown in these
diagrams is current at the time of printing,
but it may not match your machine. Always
use the wiring diagram inside the motor

to an improperly sized circuit will greatly
increase the risk of fire. To minimize
this risk, only connect the machine to a
power circuit that meets the minimum
requirements given in this manual.

Capacitors/Inverters: Some capacitors and

up to 10 minutes after being disconnected
from the power source. To reduce the risk of
being shocked, wait at least this long before
working on capacitors.

Wire/Component Damage: Damaged wires

or components increase the risk of serious
personal injury, fire, or machine damage. If
you notice that any wires or components are
damaged while performing a wiring task,
replace those wires or components before
completing the task.
