Safety Instructions For Oscillating Edge Belt/
Spindle Sander
Safety is a combination of common
sense, staying alert and knowing how
your oscillating edge belt/spindle
sander works. Read this manual to
understand this sander.
Safety Signal Words
DANGER: means if the safety infor-
mation is not followed someone will
be seriously injured or killed.
Before Using The Sander
WARNING: Some dust created by power sanding, saw in g, grin ding,
drilling, and other co nstruction activities contains chemicals k nown
(to the State of California) to cause cancer, birth defects or other
reproductive harm. Some examples of these chemicals are:
• Lead from lead-based paints,
• Crystalline silica from bricks and c ement and other masonry products, and
• Arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on h ow often you
do this type of work. To reduce your exposure to these chemicals:
work in a well ventilated area, and w ork with approved safety equipment, such as those dust masks that are special ly designed to filter
out microscopic particles.
WARNING: means if the safety infor-
mation is not followed someone
could be seriously injured or killed.
CAUTION: means if the safety infor-
mation is not followed someone ma y
be injured.
WARNING: To reduce the risk of
mistakes that could cause serious, permanent injury, do not
plug the sander in until the following steps are completed.
• A s sem bly. (See pages 12-19)
• Learn the use and function of the
ON-OFF switch. (See page 21)
• Review and understanding of all
safety instructions and operating
procedures in this manual.
• Review of the maintenance methods for this sander. (See page 29)

Safety Instructions for Oscillating Edge Belt/
Spindle Sander (continued)
Read the following WARNING labels found on the sander:
When Installing O r Moving The Sander
Avoid dange rou s envi ronment.
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.
• N e ve r use this or any power sander
for wet sanding. Doing so could
cause electrocution, serious injury
or worse.
To red uce the risk of injury from
unexpected sander moveme nt:
• 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
16.)
• 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.
4
Before Each Use
Inspect your sander. Check for:
• alignment of moving parts,
• binding of moving parts,
• broken or damaged parts,
• w o rk 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,
• w o rn or damaged electric cords,
• stable mounting, and
• any other conditions that may affect
the way the sander works.
• Remove adjusting keys and
wrenches. Form a habit of checking
for and removing keys and adjusting
wrenches from table top before turning sander on.
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 red uce 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 15)
• All sanding drums, washers and
knobs are tight. No parts should
have excessive play prior to operating unit.
• Keep work area cl ean . Cluttered
work surfaces invite accidents. Floor
must be clean and dry for stable
footing.
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 AN S I Z87.1 (or in
Canada CSA Z94.3-99) 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 operation s 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.

Safety Instructions for Oscillating Edge Belt/
Spindle Sander (continued)
• 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:
• D o not layout, assem ble, or setup
work on the sander while any parts
are moving.
• Reduce the risk of accidental
starting. Make sure swit ch is “O FF”
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 l ine 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 sandi ng 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 us e 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 support 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 o r rips.
WARNING: Don’t let familiarity
(gained from frequent use of
your sander) cause a careless
mistake. 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 visi-
tors 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
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-p roof.
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 contains lead. Therefore,
we recommend the following precautions when sanding all paints:
1. Protect your lungs. Wear a dust
mask or respirator at all times.
Wear only dust masks t h at a re suit able 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.
7
Precautions To Take When Sanding Paint
(continued)
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 outside 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.

Information
NOTE: The plug supplied on your tool
may not fit into t he outl et you ar e planni ng
to use. Your local electrical code may
require slightl y different power cord plug
connections. If these diff erences 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 malfuncti on 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 groundi ng conductor 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 p lug t o a 2-p ole outl et, a s shown,
if a properly grounded out let is not available. This temporary adapter should be
used only unti l 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 outl et box.
Improper connecti on of the equipment
grounding conductor could result in a risk
of electric shock. The conductor with i nsulation having an outer surface that is
green with or without yell ow str ipes is the
equipment grounding conductor. If repair
or replacement of the electric cord or plug
is necessary, do not connect the equipment-grounding conductor to a live terminal.
If the grounding instructions are not completely unde rstood, or if you are in doubt
as to whether the tool is properly
grounded, check with a qualified electrician or service personnel.
WARNI NG: If not properly
grounded, this tool can cause an
electrical shock, particularly
when used in damp locations, in
proximity to plu m bi ng, 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.

Motor Safety Protection
IMPORTANT: To reduce the risk of motor
damage, the motor should be blown out
or vacuumed frequently to keep sawdust
from interferi ng with normal motor ventilation.
1. Connect this tool to a power source
with the appropriate voltage for your
model and a 15 -amp bran ch cir cuit wi th
a 15-amp fuse or circ uit breaker. Using
the wrong size fuse can damage the
motor.
2. If the motor won't start, turn off the
power switch immediately and unplug
the tool. Check the spindle to make
sure it turns freel y. If the spindle is free,
try to start the motor again. If the motor
still does not start, refer to the "Troubleshooting” char t.
3. If the motor suddenly stalls while sanding, turn off the power switch, unplug
the tool, and remove the workpiece
from the belt/drum. The motor may now
be restart ed and the sanding finished.
4. Fuses may "blow" or ci rcuit breakers
may trip frequen tl y if:
a. Motor Is Overloaded-Overloading
can occur if you sand t oo rapi dly or
make too many st art/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 sm all size
wire in the supply circui t) or to overly
long supply circuit wire. Always check
the connections, the load and supply
circuit whenever motor doesn't work
well. Check wire sizes and extension
cord length with the Wire Size Chart.
