refrigerator 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 extension 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 resulting 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, neck-
ties, or jewelry that can get caught and draw you into
moving parts. Rubber gloves and nonslip footwear are
recommended when working outdoors. 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.
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.
KEE P BLA DE S CLEA N, SH ARP, 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 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. Repair or replace a damaged or worn
cord immediately. Stay constantly aware of cord location
and keep it well away from the rotating blade.

and use them to instruct others who may use this tool. If you
loan someone this tool, loan them these instructions also.
WARNING:
Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals
known 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 cement and other masonry products, and
• arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure
to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust
masks that are specially designed to filter out microscopic particles.

ELECTRICAL
ExTENSION CORDS
Use only 3-wire extension cords that have 3-prong grounding 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.
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.
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
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 conductor can result in a risk of electric shock. The conductor 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 equipmentgrounding 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.
tion or breakdown, grou
nding provides
WARNING:
Check extension cords before each use. If damaged 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.

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 working 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 particular 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.

END SANDING ON THE SANDING BELT
See Figure 19.
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.
END SANDING
Fig. 19
CURVED EDGE SANDING
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
rotation 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.

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.

Tensioning and Tracking
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 either direction.
Slide the tension lever to the left to release the belt
tension.
Remove the sanding belt.
Place the replacement sanding belt over the drums as
shown. Make sure the belt is centered on both drums.
Slide the tension lever to the right to apply belt tension.
Plug in the power cord. Insert the switch key and turn the
unit ON ( I ) and immediately OFF ( O ), noting if the belt
tends to slide off the drums. If it did not tend to slide off,
it is tracking properly.
If the sanding belt runs down towards the table, turn the
tracking knob clockwise 1/4 turn.
If the sanding belt, runs up away from the table, turn the
tracking knob counterclockwise 1/4 turn.
Turn switch ON ( I ) and immediately OFF ( O ) again, noting
belt movement. Readjust tracking knob if necessary.

MAINTENANCE
WARNING:
When servicing use only identical RIDGID replacement parts. Use of any other parts may create a
hazard or cause product damage.
WARNING:
Always wear safety goggles or safety glasses with
side shields during power tool operation or when
blowing dust. If operation is dusty, also wear a
dust mask.
GENERAL MAINTENANCE
Avoid using solvents when cleaning plastic parts. Most
plastics are susceptible to damage from various types of
commercial solvents and may be damaged by their use. Use
clean cloths to remove dirt, dust, oil, grease, etc.
WARNING:
Do not at any time let brake fluids, gasoline, petroleum-based products, penetrating oils, etc., come
in contact with plastic parts. Chemicals can damage, weaken or destroy plastic which may result in
serious personal injury.
LUBRICATION
All of the bearings in this tool are lubricated with a sufficient
amount of high grade lubricant for the life of the unit under
normal operating conditions. Therefore, no further lubrication
is required.
DUST COLLECTION CAPABILITY
See Figure 27.
A standard 2-1/2 in. dust exhaust port has been provided
to make dustless sanding possible. It is on the rear of the
sander as shown. The pickup adapter end of a vacuum hose
fits inside the dust exhaust port with a wedge fit.
Even with a dust collection system, it is necessary to periodically clean sanding dust from the recess in the table.
Sawdust buildup in the table recess may prevent the belt
or spindle from making a complete oscillation, which may
cause premature wear.
TRANSPORTING SANDER
When using the sander in a portable application, it is acceptable to lift and carry sander by the worktable or by the carry
handles. Be careful when transporting to reduce the risk of
dislodging accessories, throat plate inserts, wrench, and upper spindle washers from their respective storage areas.
Electric tools used on fiberglass material, wallboard, spackling compounds, or plaster are subject to accelerated wear
and possible premature failure because the fiberglass chips
and grindings are highly abrasive to bearings, brushes, commutators, etc. Consequently, it is not recommended using
this tool for extended work on these types of materials. However, if you do work with any of these materials, it is extremely
important to clean the tool using compressed air.
