Read the following WARNING labels found on the sander:
When Installing Or Moving The Sander
Avoid dangerous environment. Use the sander in a
dry, indoor place protected from rain. Keep work area
well lighted.
To reduce the risk of burns or other fire damage, never
use the sander near flammable liquids, vapors or gasses.
To reduce the risk of injury or death from electrical
shock:
•Ground the sander. This sander has an approved 3-
conductor cord and a 3-prong grounding type plug.
Use only 3-wire, grounded outlets rated 120 volts, 15
amperes (amps). The green conductor in the cord is
the grounding wire. To reduce the risk of electrocution,
Never connect the green wire to a live terminal.
•Make sure your fingers do not touch the plug’s metal
prongs when plugging or unplugging the sander.
•Never use this or any power sander for wet sanding.
Doing so could cause electrocution, serious injury or
worse.
To reduce the risk of injury from unexpected sander
movement:
•Always unplug the sander before moving it.
•Put the sander on a firm level surface where there is
plenty of room for handling and properly supporting the
workpiece.
•Attach rubber feet.
•Support the sander so it does not rock.
•Bolt the sander to its work surface. Use the fasteners
and method shown in “Assembly.”(See page 12.)
•Never stand on tool. Serious injury could occur if the
tool tips. Do not store anything above or near the tool
where anyone might stand on the tool to reach it.
Before Each Use
Inspect your sander. Check for:
•alignment of moving parts,
•binding of moving parts,
•broken or damaged parts,
•work parts that cause a gap larger than 1/16" between
work support and sanding surface,
•sanding belt narrower than 4 inches. Narrower belts
uncover parts that could trap your fingers,
•worn or damaged electric cords,
•stable mounting, and
•any other conditions that may affect the way the
sander works.
If any part is missing, bent, or broken in any way, or any
electrical parts don’t work properly, turn the sander off
and unplug the sander. Replace damaged, missing, or
failed parts before using the sander again.
Disconnect the sander to reduce the risk of injury from
accidental starting. Turn switch off, unplug sander and
remove the switch key before changing the setup or
sanding drum.
Maintain tools with care. Keep the sander clean for
maximum and safest performance.
To reduce the risk of injury from jams, slips or
thrown pieces:
•Use only recommended accessories.
•Use the correct spacer ring insert. The opening
between the sanding sleeve and insert must be 5/32 of
an inch or less. (See page 11)
•All sanding drums, washers and knobs are tight.
No parts should have excessive play prior to operating
unit.
•Keep work area clean. Cluttered work surfaces invite
accidents. Floor must be clean and dry for stable footing.

Safety Instructions for Oscillating Belt Edge/Spindle Sander
(continued)
Plan Ahead To Protect Your Eyes, Hands, Face and Ears
Dress for Safety
•Any power sander can throw foreign objects into the
eyes. This can result in permanent eye damage.
Always wear safety goggles, not glasses complying
with ANSI Z87.1 (or in Canada CSA Z94-3-M88)
shown on package. Everyday eyeglasses have only
impact resistant lenses. They are not safety glasses.
Safety goggles are available at many local retail
stores. Glasses or goggles not in compliance with
ANSI or CSA could seriously hurt you when they
break.
•Sanding operations are usually dusty. Wear a dust
mask along with the safety goggles.
•Wear nonslip footwear.
•Tie back long hair.
•Roll long sleeves above the elbow.
•Noise levels vary widely. To reduce the risk of possible
hearing damage, wear ear plugs or muffs when using
sander for hours at a time.
•Do not wear loose clothing, gloves, neckties or jewelry
(rings, wrist watches). They can get caught and draw
you into moving parts.
Know your sander. Read and understand the owner’s
manual and labels affixed to the tool. Learn its application
and limitations as well as the specific potential hazards.
Plan your work. Think through how you will hold and
maneuver the workpiece against the sanding drum or
belt.
Use the right tool. Don’t force tool or attachment to do a
job it was not designed to do.
To reduce the risk of injury from accidental contact
with moving parts:
•Do not layout, assemble, or setup work on the sander
while any parts are moving.
•Reduce the risk of accidental starting. Make sure
switch is “OFF”before plugging sander into a power
outlet.
Inspect your workpiece. Make sure there are no nails
or foreign objects in the part of the workpiece to be
sanded.
Plan the way you will hold the workpiece from start
to finish. Reduce the risk of awkward operations and
hand positions where a sudden slip could cause finger or
hand to move into a sanding surface.
Don’t overreach. Maintain balance and footing.
Keep face and body to one side. Stay out of line of a
possible throwback.
Plan your work to reduce the risk of THROWBACKS -
when the workpiece catches the sanding drum and is
torn from your hands:
•Make sure there is no debris between the workpiece
and its supports.
•When sanding irregularly shaped workpieces, plan
your work support so it will not slip and be pulled from
your hands.
•Use extra caution with large, very small or awkward
workpieces.
•Never use this tool to finish pieces too small to hold by hand.
•Use extra supports (tables, saw horses, blocks, etc.)
for any workpieces large enough to tip when not
secured to the work surface.
•Never use another person as a substitute for a table
extension, or as additional support for a workpiece that
is longer or wider that the basic sander table, or to help
feed, support or pull the workpiece.
•Sand only one workpiece at a time.
•Clear everything except the workpiece and related sup-
port devices off the table before turning the sander on.
•Always feed workpiece from right to left against the
direction the sanding sleeve or belt is rotating.
•Do not use drums, sanding sleeves or sanding belts
which show visual signs of wear such as grooves,
tears or rips.
WARNING: Don’t let familiarity (gained from fre-
quent use of your sander) cause a careless mis-
take. A careless fraction of a second is enough to
cause a severe injury.
When Sander is Running
Before starting your work, watch the sander while it runs.
If it makes an unfamiliar noise or vibrates excessively,
Stop Immediately. Turn the sander off. Unplug the
sander. Do not restart until identifying and correcting the
problem.
Never leave tool running unattended.
Before using the sander, make sure the sanding belt
turns clockwise, when viewed from above.
Keep children away. Keep all visitors a safe distance
from the sander and workpiece.

5
Don’t force tool. It will perform better and safer at its
designed rate. Press workpiece against the sanding
sleeve hard enough to begin sanding without bogging
down or binding spindle or belt.
Before freeing any jammed material:
•Turn switch “OFF”.
•Unplug the sander.
•Wait for all moving parts to stop.
Before Leaving The Sander
Turn switch off. Don’t leave tool until the unit comes to a
complete stop.
Make workshop child-proof. Remove the yellow switch
key. Store it away from children and others not qualified
to use the tool. Disconnect master switches. Lock the
shop.
Precautions To Take When Sanding Metals
When sanding metals, sparks or hot fragments could
cause a fire. To reduce the risk of this:
1. Disconnect any dust collecting hose from the sander.
2. Remove all traces of wood dust from inside the unit
before sanding metals.
3. Remove all traces of metal dust from inside the unit
before sanding wood again.
Precautions To Take When Sanding Paint
Sanding of lead based paint is not recommended. It is
difficult to control the contaminated dust that could cause
lead poisoning.
It is also difficult to identify whether or not a paint con-
tains lead. Therefore, we recommend the following pre-
cautions when sanding all paints:
1. Protect your lungs. Wear a dust mask or respirator at
all times. Wear only dust masks that are suitable for
working in lead paint sanding environments. Ordinary
painting masks do not offer this protection.
2. Do not allow children or pregnant women to enter the work
area until paint sanding job is complete and work area is
clean.
3. To prevent ingesting contaminated paint particles: Do
not eat, drink, or smoke in a work area where paint is
being sanded. After sanding paint, wash and clean up
before eating, drinking or smoking. Do not leave food,
drinks, or tobacco products in the work area where
dust can settle on them.
4. Protect the environment when sanding paint. Use a
dust collection system if possible. Seal the work area
with plastic if necessary. Do not track paint dust out-
side the work area.
5. Thoroughly clean the work area upon completion of
paint sanding project. If project lasts for an extended
period of time, clean work area often. Items such as
sanding dust, vacuum filter bags, plastic drop cloths, etc.
should be placed in a sealed container and disposed of
properly. Clean all items exposed to sanding dust.
Motor Specifications and Electrical Requirements
General Electrical Connections
DANGER: To reduce the risk of electrocution:
1. Use only identical replacement parts when ser-
vicing. Servicing should be performed by a
qualified service technician.
2. Do not use in rain or where floor is wet.
This tool is intended for indoor use only.
WARNING Do not to touch the terminals of plug
when installing or removing the plug to or from the
outlet.
If power cord is worn or cut, or damaged in any way,
have it replaced immediately.
Power Supply and Motor Specifications
WARNING: To reduce the risk of electrical hazards,
fire hazards or damage to the tool, use proper cir-
cuit protection. Your tool is wired at the factory for
operation using the voltage shown. Connect tool
to a power line with the appropriate voltage and a
15-amp branch circuit. To reduce the risk of shock
or fire, if power cord is worn or cut, or damaged in
any way, have it replaced immediately.
The A-C motor used on this tool is a relay start motor, hav-
ing the following specifications: It is wired at the factory for
operation on 110-120V AC, 60 Hz. operation.

Motor Specifications and Electrical Requirements (continued)
110-120 Volt, 60 Hz. Tool Information
NOTE: The plug supplied on your tool may not fit into the
outlet you are planning to use. Your local electrical code
may require slightly different power cord plug connec-
tions. If these differences exist refer to and make the
proper adjustments per your local code before your tool
is plugged in and turned on.
In the event of a malfunction or breakdown, grounding
provides a path of least resistance for electric current to
reduce the risk of electric shock. This tool is equipped
with an electric cord having an equipment grounding con-
ductor and a grounding plug, as shown. The plug must
be plugged into a matching outlet that is properly
installed and grounded in accordance with all local codes
and ordinances.
Do not modify the plug provided. If it will not fit the outlet,
have the proper outlet installed by a qualified electrician.
A temporary adapter may be used to connect this plug to
a 2-pole outlet, as shown, if a properly grounded outlet is
not available. This temporary adapter should be used
only until a properly grounded outlet can be installed by a
qualified electrician. The green colored rigid ear, lug and
the like, extension from the adapter must be connected to
a permanent ground such as a properly grounded outlet
box.
Improper connection of the equipment grounding con-
ductor could result in a risk of electric shock. The conduc-
tor with insulation having an outer surface that is green
with or without yellow stripes is the equipment grounding
conductor. If repair or replacement of the electric cord or
plug is necessary, do not connect the equipment-ground-
ing conductor to a live terminal.
If the grounding instructions are not completely under-
stood, or if you are in doubt as to whether the tool is
properly grounded check with a qualified electrician or
service personnel.
WARNING: If not properly grounded, this tool can
cause an electrical shock, particularly when used
in damp locations, in proximity to plumbing, or out
of doors. If an electrical shock occurs there is the
potential of a secondary hazard, such as your
hands contacting the sanding belt/spindle.
NOTE: The adapter illustrated is for use only if you have a
properly grounded 2-prong outlet.
NOTE: In Canada the use of a temporary adapter is not
permitted by the Canadian Electrical Code.
Motor Safety Protection
IMPORTANT: To reduce the risk of motor damage, this
motor should be blown out or vacuumed frequently to
keep sawdust from interfering with normal motor ventila-
tion.
1.Connect this tool to a power source with the appropri-
ate voltage for your model and a 15-amp branch circuit
with a 15-amp fuse or circuit breaker. Using the wrong
size fuse can damage the motor.
2. If the motor won’t start, turn off the power switch imme-
diately and unplug the tool. Check the spindle to make
sure it turns freely. If the spindle is free, try to start the
motor again. If the motor still does not start, refer to the
"Troubleshooting”chart.
3. If the motor suddenly stalls while sanding, turn off the
power switch, unplug the tool, and remove the work-
piece from the belt/drum. The motor may now be
restarted and the sanding finished.
4. Fuses may "blow" or circuit breakers may trip fre-
quently if:
a. Motor Is Overloaded-Overloading can occur if you
sand too rapidly or make too many start/stops in a
short time.
b. Line voltages should not be more than 10% above
or below the nameplate voltage. For heavy loads,
however, the voltage at motor terminals must equal
the voltage specified for your model.
5. Most motor troubles may be traced to loose or incorrect
connections, overload, low voltage (such as small size
wire in the supply circuit) or to overly long supply circuit
wire. Always check the connections, the load and sup-
ply circuit whenever motor doesn't work well. Check
wire sizes and extension cord length with the Wire Size
Chart.

Bolting Oscillating Edge Belt/Spindle
Sander To Workbench
If sander is to be used in a permanent location, it should
be fastened securely to a firm supporting surface such as
a workbench, with either bolts or drywall screws.
Fastening with screws
1. Use 1/4" screws, washers, and nuts (not included).
The screw length should be 1-1/2" plus the thickness
of the workbench.
2. Locate and mark the holes where the sander is to be
mounted.
3. Drill (4) 3/8" diameter holes through workbench.
4. Place sander on workbench, aligning holes in base
with holes drilled in workbench.
5. Insert (4) 1/4" diameter screws and washers and
attach nuts securely.
Fastening with drywall screws
Drive (4) 2-1/2" long drywall screws through the holes in
the base and through the workbench. Do not over-
tighten the screws.
CAUTION: To reduce the risk of injury from tool
movement, use either 1/4" diameter screws and
nuts or 2-1/2" long drywall screws.
Clamping Oscillating Edge Belt/Spindle
Sander To Workbench
An alternative method of mounting is to fasten the sander
to a mounting board. The board should be sufficient size
to avoid tipping while in use. Any good grade of plywood
or chipboard with a 3/4" thickness is recommended.
(Thinner chipboard can break.)
NOTE: For proper stability, holes must be countersunk so
screw heads are flush with the surface of supporting
board.
Supporting Oscillating Edge Belt/Spindle
Sander to Sawhorses
The sander has provisions for being supported by saw-
horses. The sawhorse can be built with the crosspiece

Removing/Installing the Sanding Belt
Tensioning and Tracking
WARNING: To reduce the risk of injury from acci-
dental start, make sure tool is unplugged before
removing or installing sanding belt.
Some sanding belts have a “directional arrow”on the
inside or smooth side. If there is an arrow, the belt must
run in the direction of the arrow so the splice will not
come apart. If there is no arrow the belt may be put on
any way.
1. Slide the tension lever to the left to release the belt
tension.
2. Remove the sanding belt.
3. Place the replacement sanding belt over the drums as
shown. Make sure the belt is centered on both drums.
4. Slide the tension lever to the right to apply belt tension.
5. Plug in the power cord. Insert the yellow safety key
and turn the unit “ON”and immediately “OFF”, noting if
the belt tends to slide off the drums. If it did not tend to
slide off, it is tracking properly.
6. If the sanding belt runs down towards the table, turn
the tracking knob clockwise 1/4 turn.
7. If the sanding belt, runs up away from the table, turn
the tracking knob counterclockwise 1/4 turn.

Safety Instructions for Oscillating Edge Belt/Spindle Sander
Before Using The Sander
WARNING: To reduce the risk of mistakes that
could cause serious, permanent injury, do not plug
the sander in until the following steps are com-
pleted.
•Assembly. (See pages 8-12)
•Learn the use and function of the ON-OFF switch.
(See page 16)
•Review and understanding of all safety instructions
and operating procedures in this manual.
•Review of the maintenance methods for this sander.
(See page 22)
When Installing Or Moving The Sander
Avoid dangerous environment. Use the sander in a dry,
indoor place protected from rain. Keep work area well
lighted.
To reduce the risk of burns or other fire damage, never
use the sander near flammable liquids, vapors or gasses.
To reduce the risk of injury or death from electrical
shock:
•Ground the sander. This sander has an approved 3-
conductor cord and a 3-prong grounding type plug.
Use only 3-wire, grounded outlets rated 120 volts, 15
amperes (amps). The green conductor in the cord is
the grounding wire. To reduce the risk of electrocution,
Never connect the green wire to a live terminal.
•Make sure your fingers do not touch the plug’s metal
prongs when plugging or unplugging the sander.
•Never use this or any power sander for wet sanding.
Doing so could cause electrocution, serious injury or
worse.
To reduce the risk of injury from unexpected sander
movement:
•Always unplug the sander before moving it.
•Put the sander on a firm level surface where there is
plenty of room for handling and properly supporting the
workpiece.
•Attach rubber feet.
•Support the sander so it does not rock.
•Bolt the sander to its work surface. Use the fasteners
and method shown in “Assembly.”(page 12)
•Never stand on tool. Serious injury could occur if the
tool tips. Do not store anything above or near the tool
where anyone might stand on the tool to reach them.
Before Each Use
Inspect your sander. Check for:
•alignment of moving parts,
•binding of moving parts,
•broken or damaged parts,
•work parts that cause a gap larger than 1/16" between
work support and sanding surface,
•sanding belt narrower than 4 inches. Narrower belts
uncover parts that could trap your fingers,
•worn or damaged electric cords,
•stable mounting, and
•any other conditions that may affect the way the
sander works.
If any part is missing, bent, or broken in any way, or any
electrical parts don’t work properly, turn the sander off
and unplug the sander. Replace damaged, missing, or
failed parts before using the sander again.
Disconnect the sander to reduce the risk of injury from
accidental starting. Turn switch off, unplug sander and
remove the switch key before changing the setup or
sanding drum.
Maintain tools with care. Keep the sander clean for
maximum and safest performance.
To reduce the risk of injury from jams, slips or
thrown pieces:
•Use only recommended accessories.
•Use the correct spacer ring insert. The opening
between the sanding sleeve and insert must be 5/32 of
an inch or less. (See page 11)
•All sanding drums, washers and knobs are tight.
No parts should have excessive play prior to operating
unit.
•Keep work area clean. Cluttered work surfaces invite
accidents. Floor must be clean and dry for stable foot-
ing.

Safety Instructions for Oscillating Edge Belt/ Spindle Sander
(continued)
Plan Ahead To Protect Your Eyes, Hands, Face and Ears
Dress for Safety
•Any power sander can throw foreign objects into the
eyes. This can result in permanent eye damage.
Always wear safety goggles, not glasses complying
with ANSI Z87.1 (or in Canada CSA Z94-3-M88)
shown on package. Everyday eyeglasses have only
impact resistant lenses. They are not safety glasses.
Safety goggles are available at many local retail stores.
Glasses or goggles not in compliance with ANSI or
CSA could seriously hurt you when they break.
•For dusty operations, wear a dust mask along with
safety goggles.
•Wear nonslip footwear.
•Tie back long hair.
•Roll long sleeves above the elbow.
•Noise levels vary widely. To reduce the risk of possible
hearing damage, wear ear plugs or muffs when using
sander for hours at a time.
•Sanding operations are usually dusty. Wear a dust
mask along with the safety goggles.
•Do not wear loose clothing, gloves, neckties or jewelry
(rings, wrist watches). They can get caught and draw
you into moving parts.
Know your sander. Read and understand the owner’s
manual and labels affixed to the tool. Learn its application
and limitations as well as the specific potential hazards.
Plan your work. Think through how you will hold and
maneuver the workpiece against the sanding drum or
belt.
Use the right tool. Don’t force tool or attachment to do a
job it was not designed to do.
To reduce the risk of injury from accidental contact
with moving parts:
•Do not layout, assemble, or setup work on the sander
while any parts are moving.
•Reduce the risk of accidental starting. Make sure
switch is “OFF”before plugging sander into a power
outlet.
Inspect your workpiece make sure there are no nails or
foreign objects in the part of the workpiece to be sanded.
Plan the way you will hold the workpiece from start to
finish. Reduce the risk of awkward operations and hand
positions where a sudden slip could cause finger or hand
to move into a sanding surface.
Don’t overreach. Maintain balance and footing.
Keep face and body to one side. Stay out of line with a
possible throwback.
Plan your work to reduce the risk of THROWBACKS -
when the workpiece catches the sanding drum and is
torn from your hands:
•Make sure there’s no debris between the workpiece
and its supports.
•When sanding irregularly shaped workpieces, plan
your work support so it will not slip and be pulled from
your hands.
•Use extra caution with large, very small or awkward
workpieces.
•Never use this tool to finish pieces too small to hold by hand.
•Use extra supports (tables, saw horses, blocks, etc.)
for any workpieces large enough to tip when not
secured to the work surface.
•Never use another person as a substitute for a table
extension, or as additional support for a workpiece that
is longer or wider that the basic sander table, or to help
feed, support or pull the workpiece.
•Sand only one workpiece at a time.
•Clear everything except the workpiece and related sup-
port devices off the table before turning the sander on.
•Always feed workpiece from left to right against the
direction the drum sleeve is rotating.
•Do not use drums, sanding sleeves or belts which
show visual signs of wear such as grooves, tears or
rips.
WARNING: Don’t let familiarity (gained from fre-
quent use of your sander) cause a careless mis-
take. A careless fraction of a second is enough to
cause a severe injury.
When Sander is Running
Before starting your work, watch the sander while it runs.
If it makes an unfamiliar noise or vibrates excessively,
Stop Immediately. Turn the sander off. Unplug the
sander. Do not restart until identifying and correcting the
problem.
Never leave tool running unattended.
Before using the sander, make sure the sanding belt
turns clockwise, when viewed from above.
Keep children away. Keep all visitors a safe distance
from the sander and workpiece.
Don’t force tool. It will perform better and safer at its
designed rate. Press workpiece against the sanding
sleeve or belt hard enough to begin sanding without bog-
ging down or binding spindle.
Before freeing any jammed material:
•Turn switch “OFF”.
•Unplug the sander.
•Wait for all moving parts to stop.

19
Before Leaving The Sander
Turn switch off. Don’t leave tool until the unit comes to a
complete stop.
Make workshop child-proof. Remove the yellow switch
key. Store it away from children and others not qualified
to use the tool. Disconnect master switches. Lock the
shop.
Precautions To Take When Sanding Metals
When sanding metals, sparks or hot fragments could
cause a fire. To reduce the risk of this:
1. Disconnect any dust collecting hose from the sander.
2. Remove all traces of wood dust from inside the unit
before sanding metals.
3. Remove all traces of metal dust from inside the unit
before sanding wood again.
Precautions To Take When Sanding Paint
Sanding of lead based paint is not recommended. It is
difficult to control the contaminated dust that could cause
lead poisoning.
It is also difficult to identify whether or not a paint con-
tains lead. Therefore, we recommend the following pre-
cautions when sanding all paints:
1. Protect your lungs. Wear a dust mask or respirator at
all times. Wear only dust masks that are suitable for
working in lead paint sanding environments. Ordinary
painting masks do not offer this protection.
2. Do not allow children or pregnant women to enter the work
area until paint sanding job is complete and work area is
clean.
3. To prevent ingesting contaminated paint particles: Do
not eat, drink, or smoke in a work area where paint is
being sanded. After sanding paint, wash and clean up
before eating, drinking or smoking. Do not leave food,
drinks, or tobacco products in the work area where
dust can settle on them.
4. Protect the environment when sanding paint. Use a
dust collection system if possible. Seal the work area
with plastic if necessary. Do not track paint dust out-
side the work area.
5. Thoroughly clean the work area upon completion of
paint sanding project. If project lasts for an extended
period of time, clean work area often. Items such as
sanding dust, vacuum filter bags, plastic drop cloths, etc.
should be placed in a sealed container and disposed of
properly. Clean all items exposed to sanding dust.
Basic Sanding Operation
Sandpaper Selection
Selecting the correct size diameter, correct size grit, and
correct type sandpaper is an extremely important step in
achieving a high quality sanded finish. Aluminum oxide,
silicon carbide, and other synthetic abrasives are best for
power sanding. Natural abrasives, such as flint and gar-
net, are too soft for economical use in power sanding.
In general, coarse grit will remove the most material and
finer grit will produce the best finish in all sanding opera-
tions. The condition of the surface to be sanded will
determine which grit will do the job. If the surface is
rough, start with a coarse grit and sand until the surface
is uniform. Medium grit may then be used to remove
scratches left by the coarser grit and finer grit used for fin-
ishing of the surface. Always continue sanding with each
grit until surface is uniform.
NOTE: Do Not use sander without sandpaper. Doing so
will damage the rubber drum.
Select and install the desired sanding sleeve for your par-
ticular application. Sanding sleeves from 1/2" to 2" can be
used with this sander. Choose one that is close in size to
the workpiece you are sanding. Also install the appropri-
ate spacer ring insert (page 11).
WARNING: Failure to use the correct size spacer
ring insert with its matching sanding sleeve could
result in fingers being pinched or the workpiece
being pulled down between the spacer ring insert
and sanding sleeve.
NOTE: The correct size sanding belt is 4" x 24". These
belts are available in coarse, medium and fine grits.

Surface Sanding on the Sanding Belt
WARNING: To reduce the risk of injury from slips,
jams or thrown pieces, adjust the backstop to clear
the sanding surface by no more than 1/16 of an
inch. When checking clearance between the belt
and backstop, press the belt flat against the metal
beneath it.
Hold the workpiece firmly with both hands, keeping fin-
gers away from the sanding belt.
Keep the end butted against the backstop and move the
work evenly across the sanding belt. Use caution when
sanding very thin pieces.
For sanding long pieces the backstop can be rotated out
of the way.
Apply only enough pressure to allow the sanding belt to
remove material.
End Sanding on the Sanding Belt
Move the work evenly across the sanding belt. For accu-
racy, use a miter gauge accessory (not included).
Sanding Curved Edges
Inside curves are best sanded with the sander assem-
bled in the spindle mode. However, inside curves larger
than 1-1/2" may be sanded on the drive drum when in the
belt sander mode.
Although it is possible to lightly sand on the idler drum
end of the belt sanding assembly, we do not recommend
it.
The idler drum is an integral part of the belt tracking
mechanism. It is spring loaded to maintain proper tension.
Use of the idler drum to sand curves may cause belt to
track improperly.
