as well as specific potential hazards related to this tool.
 GUARD AGAINST ELECTRICAL SHOCK BY
PREVENTING BODY CONTACT WITH GROUNDED
SURFACES. For example: pipes, radiators, ranges, re-
frigerator enclosures.
 KEEP GUARDS IN PLACE and in working order.
 REMOVE ADJUSTING KEYS AND WRENCHES. Form
habit of checking to see keys and adjusting wrenches are
removed from tool before turning it on.
KEEP THE WORK AREA CLEAN. Cluttered work areas
and work benches invite accidents. DO NOT leave tools
or pieces of wood on the tool while it is in operation.
 DO NOT USE IN DANGEROUS ENVIRONMENTS. Do
not use power tools in damp or wet locations or expose
them to rain. Keep the work area well lit.
 KEEP CHILDREN AND VISITORS AWAY. All visitors
should wear safety glasses and be kept a safe distance
from work area. Do not let visitors contact tool or exten-
sion cord while operating.
 MAKE WORKSHOP CHILDPROOF with padlocks,
master switches, or by removing starter keys.
 DON’T FORCE THE TOOL. It will do the job better and
safer at the rate for which it was designed.
 USE THE RIGHT TOOL. Do not force the tool or attach-
ment to do a job for which it was not designed.
 USE THE PROPER EXTENSION CORD. Make sure your
extension cord is in good condition. Use only a cord heavy
enough to carry the current your product will draw. An
undersized cord will cause a drop in line voltage result-
ing in loss of power and overheating. A wire gauge size
(A.W.G.) of at least 16 is recommended for an extension
cord 25 feet or less in length. If in doubt, use the next
heavier gauge. The smaller the gauge number, the heavier
the cord.
 DRESS PROPERLY. Do not wear loose clothing, gloves,
neckties, or jewelry. They can get caught and draw you
into moving parts. Also wear protective hair covering to
contain long hair.
 ALWAYS WEAR SAFETY GLASSES WITH SIDE
SHIELDS. Everyday eyeglasses have only impact-resis-
tant lenses, they are NOT safety glasses.
 SECURE WORK. Use clamps or a vise to hold work when
practical, it is safer than using your hand and frees both
hands to operate the tool.
GENERAL SAFETY RULES
 DO NOT OVERREACH. Keep proper footing and balance
at all times.
 MAINTAIN TOOLS WITH CARE. Keep tools sharp and
clean for best and safest performance. Follow instructions
for lubricating and changing accessories.
 DISCONNECT TOOLS. When not in use, before servic-
ing, or when changing attachments, blades, bits, cutters,
etc., all tools should be disconnected from power source.
 AVOID ACCIDENTAL STARTING. Be sure switch is off
when plugging in any tool.
 USE RECOMMENDED ACCESSORIES. Consult the
operator’s manual for recommended accessories. The
use of improper accessories may result in injury.
 NEVER STAND ON TOOL. Serious injury could occur if
the tool is tipped.
CHECK DAMAGED PARTS. Before further use of the
tool, a guard or other part that is damaged should be
carefully checked to determine that it will operate properly
and perform its intended function. Check for alignment
of moving parts, binding of moving parts, breakage of
parts, mounting and any other conditions that may affect
its operation. A guard or other part that is damaged must
be properly repaired or replaced by an authorized service
center to avoid risk of personal injury.
 USE THE RIGHT DIRECTION OF FEED. Feed work into
a blade, cutter, or sanding spindle against the direction
or rotation of the blade, cutter, or sanding spindle only.
 NEVER LEAVE TOOL RUNNING UNATTENDED. TURN
THE POWER OFF. Don’t leave tool until it comes to a
complete stop.
 PROTECT YOUR LUNGS. Wear a face or dust mask if
the cutting operation is dusty.
 PROTECT YOUR HEARING. Wear hearing protection
during extended periods of operation.
 DO NOT ABUSE CORD. Never carry tool by the cord or
yank it to disconnect from receptacle. Keep cord from
heat, oil, and sharp edges.
USE OUTDOOR EXTENSION CORDS. When tool
is used outdoors, use only extension cords with
approved ground connection that are intended for use
outdoors and so marked.
 KEEP BLADES CLEAN, SHARP, AND WITH
SUFFICIENT SET. Sharp blades minimize stalling
and kickback.
NEVER USE IN AN EXPLOSIVE ATMOSPHERE.
Normal sparking of the motor could ignite fumes.
INSPECT TOOL CORDS PERIODICALLY. If dam-
aged, have repaired by a qualified service technician at
an authorized service facility. The conductor with insula-
tion 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 neces-
sary, do not connect the equipment-grounding conductor
to a live terminal. Repair or replace a damaged or worn
cord immediately. Stay constantly aware of cord location
and keep it well away from the rotating blade.

ELECTRICAL
SPEED AND WIRING
The no-load speed of this tool is approximately 1,725
rpm. This speed is not constant and decreases under a
load or with lower voltage. For voltage, the wiring in a
shop is as important as the motor’s horsepower rating. A
line intended only for lights cannot properly carry a power
tool motor. Wire that is heavy enough for a short distance
will be too light for a greater distance. A line that can
support one power tool may not be able to support two
or three tools.
GROUNDING INSTRUCTIONS
In the event of a malfunc tion or breakdown, grou nding 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 conductor and a grounding
plug. 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.
Improper connection of the equipment-grounding con-
ductor can 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-
grounding conductor to a live terminal.
Check with a qualified electrician or service personnel if the
grounding instructions are not completely understood, or if
in doubt as to whether the tool is properly grounded.
Repair or replace a damaged or worn cord immediately.
This tool is intended for use on a circuit that has an outlet
like the one shown in figure 1. It also has a grounding pin
like the one shown.
EXTENSION CORDS
Use only 3-wire extension cords that have 3-prong ground-
ing plugs and 3-pole receptacles that accept the tool's plug.
When using a power tool at a considerable distance from
the power source, use an extension cord heavy enough
to carry the current that the tool will draw. An undersized
extension cord will cause a drop in line voltage, resulting in
a loss of power and causing the motor to overheat. Use the
chart provided below to determine the minimum wire size
required in an extension cord. Only round jacketed cords
listed by Underwriter's Laboratories (UL) should be used.

**Used on 12 gauge - 20 amp circuit.
NOTE: AWG = American Wire Gauge
When working with the tool outdoors, use an extension cord
that is designed for outside use. This is indicated by the
letters “WA” on the cord's jacket.
Before using an extension cord, inspect it for loose or
exposed wires and cut or worn insulation.
WARNING:
Keep the extension cord clear of the working area.
Position the cord so that it will not get caught on
lumber, tools or other obstructions while you are
working with a power tool. Failure to do so can
result in serious personal injury.
WARNING:
Check extension cords before each use. If dam-
aged replace immediately. Never use tool with a
damaged cord since touching the damaged area
could cause electrical shock resulting in serious
injury.
ELECTRICAL CONNECTION
This tool is powered by a precision built electric motor. It
should be connected to a power supply that is 120 volts,
60 Hz, AC only (normal household current). Do not operate
this tool on direct current (DC). A substantial voltage drop
will cause a loss of power and the motor will overheat. If the
saw does not operate when plugged into an outlet, double
check the power supply.

WARNING:
Do not allow familiarity with your tool to make you
careless. Remember that a careless fraction of a
second is sufficient to inflict severe injury.
WARNING:
Always wear safety goggles or safety glasses with
side shields when operating tools. Failure to do so
could result in objects being thrown into your eyes,
resulting in possible serious injury.
APPLICATIONS
This product has been designed only for the purposes listed
below:
 Oscillating and Rotary Motion – for fast, burn free finishes
on edges, faces, contours, inside and outside curves.

OPERATION
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.
Before using the sander, make sure the sanding belt turns
clockwise, when viewed from above.
Don’t force tool. It will perform better and safer at its de-
signed rate. Press workpiece against the sanding sleeve or
belt hard enough to begin sanding without bogging down
or binding spindle.
BEFORE FREEING ANY JAMMED MATERIAL:
Turn switch OFF ( O ).
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 childproof. Remove the switch key. Store it
away from children and others not qualified to use the tool.
Disconnect master switches. Lock the shop.

OPERATION
PRECAUTIONS TO TAKE WHEN SANDING
METALS
When sanding metals, sparks or hot fragments could cause
a fire. To reduce the risk of this:
Disconnect any dust collecting hose from the sander.
Remove all traces of wood dust from inside the unit before
sanding metals.
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:
Protect your lungs. Wear a dust mask or respirator at all
times. Wear only dust masks that are suitable for work-
ing in lead paint sanding environments. Ordinary painting
masks do not offer this protection.
 Do not allow children or pregnant women to enter the work
area until paint sanding job is complete and work area is
clean.
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.
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 garnet,
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 operations. 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 finishing 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 the particu-
lar application. Sanding sleeves from 1/2 in. to 2 in. can be
used with this sander. Choose one that is close in size to
the workpiece you are sanding. Also install the appropriate
throat plate insert (page 16).
WARNING:
Failure to use the correct size throat plate insert
with its matching sanding sleeve could result in
fingers being pinched or the workpiece being
pulled down between the throat plate insert and
sanding sleeve.
NOTE: The correct size sanding belt is 4 in. x 24 in. These
belts are available in coarse, medium and fine grits.
SURFACE SANDING ON THE SANDING BELT
See Figure 18.
WARNING:
To reduce the risk of injury from slips, jams or
thrown pieces, adjust the work rest to clear the
sanding surface by no more than 1/16 of an inch.
When checking clearance between the sanding belt
and work rest, press the sanding belt flat against
the metal worktable beneath it.
Hold the workpiece firmly with both hands, keeping fin-
gers away from the sanding belt.
Keep the end butted against the work rest and move the
work evenly across the sanding belt. Use caution when
sanding very thin pieces.
For sanding long pieces the work rest can be rotated out
of the way.
Apply only enough pressure to allow the sanding belt to
remove material.
Do not sand thin pieces that may become trapped be-
tween the belt and work rest.

Move the work evenly across the sanding belt. For
accuracy, use a miter gauge accessory (not included).
SANDING CURVED EDGES
See Figure 20.
Inside curves are best sanded with the sander assembled
in the spindle mode. However, inside curves larger than
1-1/2 in. 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, it is not recommended. 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.
FEED DIRECTION
See Figure 21.
WARNING:
To prevent thrown workpiece, feed workpiece
against sanding sleeve from left to right as shown.
The sanding sleeve rotates clockwise. Feed the workpiece
against the sanding sleeve from left to right as shown. When
fed from left to right, the rotation of the sanding sleeve sands
against the workpiece. If fed in the opposite direction, the ro-
tation forces of the spinning sanding sleeve will tend to throw
or bounce the workpiece away from the sanding sleeve. This
could cause loss of control of workpiece or possible injury.

SQUARING FRONT TABLE
See Figure 22.
NOTE: Use a combination square to check the angle of the
front table with the sanding belt.
If the front table is not 90° to the sanding belt:
Use the hex key provided and “back out” both set screws
located on each side of the table.
Loosen the front table lock knob and adjust the front table
90° to the sanding belt.
Tighten the front table lock knob.
Adjust both set screws to contact the front table.
Adjust detent if necessary
Loosen the two pan head screws that secure the detent.
Adjust detent so that it engages the notches in the bracket
table lock.
Tighten the two pan head screws.
ALIGNING BELT TO MITER GAUGE SLOT
See Figure 23.
The sanding belt is installed at the factory; however, check
and make sure the belt is parallel to the miter gauge groove:
Use a combination square to check the distance from the
miter gauge groove to the belt assembly as shown.
If adjustment is required, use a 5/32 in. hex key provided
with unit to loosen the two flat head socket recess screws
on the table.
Adjust the worktable as needed to make it parallel or
same distance to the miter gauge slot.
Tighten two screws.
