RULES FOR SAFE OPERATION
Safe operation of this power tool requires that you read and
understand this operator's manual and all labels affixed to
the tool. Safety is a combination of common sense, staying
alert, and knowing how your table saw works.
READ ALL INSTRUCTIONS
KNOW YOUR POWER TOOL. Read the operator's
manual carefully. Learn the saw's applications and
limitations as well as the specific potential hazards related
to this tool.
GUARD AGAINST ELECTRICAL SHOCK BY
PREVENTING BODY CONTACT WITH GROUNDED
SURFACES. For example; pipes, radiators, ranges,
refrigerator enclosures.
KEEP GUARDS IN PLACE and in working order. Never
operate the tool with any guard or cover removed. Make
sure all guards are operating properly before each use.
REMOVE ADJUSTING KEYS AND WRENCHES. Form
habit of checking to see that keys and adjusting wrenches
are removed from tool before turning it on.
KEEP WORK AREA CLEAN. Cluttered areas and
benches invite accidents. DO NOT leave tools or pieces
of wood on the saw while it is in operation.
AVOID DANGEROUS ENVIRONMENT. Don't use power
tools in damp or wet locations or expose to rain. Keep
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 or
master switches, or by removing starter keys.
DON'T FORCE TOOL. It will do the job better and safer
at the feed rate for which it was designed.
USE RIGHT TOOL. Don't force tool or attachment to do
a job it was not designed for. Don't use it for a purpose not
intended.
MAKE SURE YOUR EXTENSION CORD IS IN GOOD
CONDITION. When using an extension cord, be sure to
use one 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
gage size (A.W.G.) of at least 14 is recommended for an
extension cord 25 feet or less in length. If in doubt, use the
next heavier gage. The smaller the gage 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. Rubber gloves and nonskid 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 impactresistant lenses; they are NOT safety glasses.
SECURE WORK. Use clamps or a vise to hold work when
practical. It's safer than using your hand and frees both
hands to operate tool.
DON'T OVERREACH. Keep proper footing and balance
at all times.
MAINTAIN TOOLS WITH CARE. Keep tools sharp and
clean for better and safer performance. Follow instructions
for lubricating and changing accessories.
DISCONNECT TOOLS. When not in use, before servicing,
or when changing attachments, blades, bits, cutters, etc.,
all tools should be disconnected.
AVOID ACCIDENTAL STARTING. Be sure switch is off
when plugging in.
USE RECOMMENDED ACCESSORIES. The use of
improper accessories may cause risk of injury.
NEVER STAND ON TOOL. Serious injury could occur if
the tool is tipped or if the cutting tool is unintentionally
contacted.
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 or cutter against the direction of rotation of blade
or cutter only.
NEVER LEAVE TOOL RUNNING UNATTENDED. TURN
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.
DON'T ABUSE CORD. Never yank cord 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.
ALWAYS KEEP THE BLADE GUARD AND RIVING
KNIFE (SPLITTER) IN PLACE and in working order.
KEEP BLADES CLEAN AND SHARP. Sharp blades
minimize stalling and kickback.
KEEP HANDS AWAY FROM CUTTING AREA. Keep
hands away from blades. Do not reach underneath work
or around or over the blade while blade is rotating. Do not
attempt to remove cut material when blade is moving.

RULES FOR SAFE OPERATION
BLADES COAST AFTER TURN OFF.
NEVER USE IN AN EXPLOSIVE ATMOSPHERE. Normal
sparking of the motor could ignite fumes.
INSPECT TOOL CORDS PERIODICALLY. If damaged,
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.
INSPECT EXTENSION CORDS PERIODICALLY and
replace if damaged.
KEEP TOOL DRY, CLEAN, AND FREE FROM OIL AND
GREASE. Always use a clean cloth when cleaning.
Never use brake fluids, gasoline, petroleum-based
products, or any solvents to clean tool.
STAY ALERT AND EXERCISE CONTROL. Watch what
you are doing and use common sense. Do not operate tool
when you are tired. Do not rush.
DO NOT USE TOOL IF SWITCH DOES NOT TURN IT
ON AND OFF. Have defective switches replaced by an
authorized service center.
GUARD AGAINST KICKBACK. Kickback occurs when
the blade stalls rapidly and workpiece is driven back
towards the operator. It can pull your hand into the blade
resulting in serious personal injury. Stay out of blade path
and turn switch off immediately if blade binds or stalls.
USE RIP FENCE. Always use a fence or straight edge
guide when ripping.
SUPPORT LARGE PANELS. To minimize risk of blade
pinching and kickback, always support large panels.
BEFORE MAKING A CUT, BE SURE ALL
ADJUSTMENTS ARE SECURE.
USE ONLY CORRECT BLADES. Do not use blades with
incorrect size holes. Never use blade washers or bolts that
are defective or incorrect. The maximum blade capacity of
your saw is 10 in. (254 mm).
AVOID CUTTING NAILS. Inspect for and remove all nails
from lumber before cutting.
NEVER TOUCH BLADE or other moving parts during
use.
NEVER START A TOOL WHEN ANY ROTATING
COMPONENT IS IN CONTACT WITH THE WORKPIECE.
DO NOT OPERATE THIS TOOL WHILE UNDER THE
INFLUENCE OF DRUGS, ALCOHOL, OR ANY
MEDICATION.
GROUND ALL TOOLS. If tool is equipped with three-
prong plug, it should be plugged into a three-hole electrical
receptacle.
WHEN SERVICING use only identical Ryobi replacement
parts. Use of any other parts may create a hazard or
cause product damage.
REMOVE ALL FENCES AND AUXILIARY TABLES
before transporting saw. Failure to do so can result in an
accident causing possible serious personal injury.
ALWAYS USE BLADE GUARD, RIVING KNIFE, AND
ANTI-KICKBACK PAWLS on all "through-sawing" operations. Through-sawing operations are those in which
the blade cuts completely through the workpiece as in
ripping or crosscutting. Keep the blade guard down, the
anti-kickback pawls down, and the riving knife in place
over the blade.
ALWAYS SECURE WORK firmly against rip fence or
miter fence.
ALWAYS USE A PUSH STICK FOR RIPPING NARROW
STOCK. A push stick is a device used to push a workpiece
through the blade instead of using your hands. Size and
shape can vary but the push stick must always be narrower than the workpiece to prevent the push stick from
contacting the saw blade. When ripping narrow stock,
always use a push stick, so your hand does not come
close to the saw blade. Use a featherboard and push
blocks for non-through cuts.
NEVER perform any operation "freehand" which means
using only your hands to support or guide the workpiece.
Always use either the rip fence or miter fence to position
and guide the work.
NEVER stand or have any part of your body in line with the
path of the saw blade.
NEVER reach behind, over, or within three inches of the
blade or cutter with either hand for any reason.
MOVE THE RIP FENCE out of the way when crosscutting.
NEVER use rip fence as cutoff gage when crosscutting.
NEVER attempt to free a stalled saw blade without first
turning the saw OFF and disconnecting the saw from the
power source.
PROVIDE ADEQUATE SUPPORT to the rear and sides
of the saw table for wide or long work pieces. Use a sturdy
"outrigger" support if a table extension more than 24
inches long is attached to the saw.
AVOID KICKBACKS (work thrown back toward you) by:
A. Keeping blade sharp.
B. Keeping rip fence parallel to the saw blade.
C. Keeping riving knife, anti-kickback pawls, and blade
guard in place and operating.
D. Not releasing the work before it is pushed all the way
past the saw blade using a push stick.
E. Not ripping work that is twisted or warped or does not
have a straight edge to guide along the fence.
AVOID AWKWARD OPERATIONS AND HAND POSI-
TIONS where a sudden slip could cause your hand to
move into the cutting tool.

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.
Length of Extension Cord Wire Size (A.W.G.)
Up to 25 feet 14
26-50 feet 12
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. Repair or replace
a damaged or worn cord immediately.
CAUTION:
Keep the cord away from the cutting area and position the
cord so that it will not be caught on lumber, tools, or other
objects during cutting.
ELECTRICAL CONNECTION
Your Ryobi Table Saw is powered by a precision built electric
motor. It should be connected to a power supply that is 120
volts, 60Hz, 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.
GROUNDING INSTRUCTIONS
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 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 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

WARNING:
Although some of the illustrations in this manual are
shown with the blade guard removed for clarity, do not
operate the saw without the blade guard unless specifically
instructed to do so.
OPERATING COMPONENTS
The upper portion of the blade projects up through the table,
surrounded by an insert called the throat plate. To cut wood
at a bevel, the blade must be tilted, using the bevel handle,
scale, and bevel indicator found on the front of the cabinet.
Inside the cabinet, adjustable positive stops are provided for
0° and 45°.
Your saw includes a rip fence and miter gauge with undertable
storage for easy accessibility. The sliding table extension
can be moved to provide 27 inches of rip capacity. The rip
fence is used to position work that will be cut lengthwise. A
scale on the front rail shows the distance between the rip
fence and the blade.
The leg stand places the table saw at convenient working
level. Once folded, the leg stand wheels make moving and
storage easy.
The blade guard assembly includes a riving knife which is a
metal device directly behind and above the blade. It is used
to help keep the cut wood from binding together and causing
possible kickback. It is very important to use the riving knife
for all through-sawing operations. The anti-kickback pawls
(also a part of the blade guard assembly) are toothed plates
mounted on the riving knife. Their teeth point away from the
work in case the work should be pulled back, toward the
operator. Then the teeth dig into the wood to help prevent or
reduce the possibility of kickback.
WARNING:
Always remove the switch key when the tool is not in use
and keep it in a safe place. In the event of a power failure,
turn the switch off ( ) and remove the key. This action
will prevent the tool from accidentally starting when power
returns.
WARNING:
ALWAYS make sure your workpiece is not in contact with
the blade before operating the switch to start the tool.
Failure to heed this warning may cause the workpiece to
be kicked back toward the operator and result in serious
personal injury.
WARNING:
To reduce the risk of accidental starting, ALWAYS make
sure the switch is in the off ( ) position before plugging
tool into the power source .

rpm. The speed will not remain constant but will be less
under a load. The wiring in a shop is as important as the
motor's horsepower rating. A line intended for lights only
WILL NOT 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.

WARNING:
To prevent possible electrical hazards, have a qualified
electrician check the line if you are not certain that it is
properly wired.

OPERATION
BASIC OPERATION OF THE TABLE SAW
A table saw can be used for straight-line cutting operations
such as cross cutting, ripping, mitering, beveling, and compound cutting. It can dado with optional accessories.
The 3-prong plug must be plugged into a matching outlet that
is properly installed and grounded according to all local
codes and ordinances. Improper connection of the equipment can result in electric shock. Check with an electrician or
service personnel if you are unsure about proper grounding.
Do not modify the plug; if it will not fit the outlet, have the
correct outlet installed by a qualified electrician. Refer to the
Electrical
Note: This table saw is designed to cut wood and wood
composition products only.
page of this manual.
CAUSES OF KICKBACK
Kickback can occur when the blade stalls or binds, kicking
the workpiece back toward you with great force and speed.
If your hands are near the saw blade, they may be jerked
loose from the workpiece and may contact the blade. Obviously, kickback can cause serious injury, and it is well worth
using precautions to avoid the risks.
Kickback can be caused by any action that pinches the blade
in the wood, such as the following:
Making a cut with incorrect blade depth
Sawing into knots or nails in the workpiece
Twisting the wood while making a cut
Failing to support work
Forcing a cut
Cutting warped or wet lumber
Using the wrong blade for the type of cut
Not following correct operating procedures
Misusing the saw
Failing to use the anti-kickback pawls
Cutting with a dull, gummed-up, or improperly set blade
AVOIDING KICKBACK
Always use the correct blade depth setting. The top of
the blade teeth should clear the workpiece by 1/8 in. to
1/4 in.
Inspect the work for knots or nails before beginning a cut.
Knock out any loose knots with a hammer. Never saw into
a loose knot or nail.
Always use the rip fence when rip cutting and the miter
gauge when cross cutting. This helps prevent twisting the
wood in the cut.
Always use clean, sharp, and properly-set blades. Never
make cuts with dull blades.
To avoid pinching the blade, support the work properly
before beginning a cut.
When making a cut, use steady, even pressure. Never
force cuts.
Do not cut wet or warped lumber.
Always hold your workpiece firmly with both hands or with
pushsticks. Keep your body in a balanced position to be
ready to resist kickback should it occur. Never stand
directly in line with the blade.
Use the right type of blade for the cut being made.
Use the blade guard assembly for all through cuts.
CUTTING AIDS
See Figure 18.
Pushsticks are devices used for safely pushing a workpiece
through the blade instead of using your hands. They can be
made in various sizes and shapes from scrap wood to use in
a specific project. The stick must be narrower than the
workpiece, with a 90˚ notch in one end and shaping for a grip
on the other end.
A pushblock has a handle fastened by recessed screws from
the underside. Use it on non-through cuts.
CAUTION:
Be sure the screw is recessed to avoid damaging the saw
or workpiece.
PUSHSTICKS
PUSHBLOCKS
Fig. 18
WARNING:
Never stand directly in line with the blade or allow hands
to come closer than 3 in. to the blade. Do not reach over
or across the blade. Failure to heed this warning can
result in serious personal injury.
CUTTING TIPS
Dado and rabbet cuts are non-through cuts which can be
either rip cuts or cross cuts. Carefully read and understand
all sections of this operator’s manual before attempting any
operation.
WARNING:
All blades and dado sets must be rated for at least 5,500
RPM to prevent possible injury.
Page 20
Page 21
OPERATION
The kerf (the cut made by the blade in the wood) will be
wider than the blade to avoid overheating or binding.
Make allowance for the kerf when measuring wood.
Make sure the kerf is made on the waste side of the
measuring line.
Cut the wood with the finish side up.
Knock out any loose knots with a hammer before making
the cut.
Always provide proper support for the wood as it comes
out of the saw.

Cross Cut
TYPES OF CUTS
See Figure 19.
There are six basic cuts: 1) the cross cut, 2) the rip cut, 3) the
miter cut, 4) the bevel cross cut, 5) the bevel rip cut, and 6)
the compound (bevel) miter cut. All other cuts are combinations of these basic six. Operating procedures for making
each kind of cut are given later in this section.
WARNING:
Always make sure the blade guard and anti-kickback
pawls are in place and working properly when making
these cuts to avoid possible injury.
Cross cuts are straight 90° cuts made across the grain of the
workpiece. The wood is fed into the cut at a 90° angle to the
blade, and the blade is vertical.
Rip cuts are made with the grain of the wood. To avoid
kickback while making a rip cut, make sure one side of the
wood rides firmly against the rip fence.
Miter cuts are made with the wood at any angle to the blade
other than 90°. The blade is vertical.
WARNING:

Rip Cut
3
Miter Cut
4
Bevel Cross Cut
5
Always use a pushstick with small pieces of wood, and
also to finish the cut when ripping a long narrow piece of
wood, to prevent your hands from getting close to the
blade.
Bevel cuts are made with an angled blade. Bevel cross cuts
are across the wood grain, and bevel rip cuts are with the
grain. The rip fence must always be on the right side of the
blade for bevel rip cuts.
Compound (or bevel) miter cuts are made with an angled
blade on wood that is angled to the blade. Be thoroughly
familiar with making cross cuts, rip cuts, bevel cuts, and miter
cuts before trying a compound miter cut.

piece, use a push stick to move the piece through the cut
and past the blade.
When the cut is made, turn the saw off ( ). Wait for the
blade to come to a complete stop before removing the
workpiece.
After the blade has stopped completely, remove the cutoff
stock.
Grasp the workpiece from the lead end (the end fed into
the blade first) and carefully remove it from the table.

OPERATION
TO MAKE A COMPOUND MITER CUT
It is recommended that you place the piece to be saved on
the left side of the blade and that you make a test cut on
scrap wood first.
WARNING:
Make sure the blade guard assembly is securely installed
and working properly to avoid serious personal injury.
Remove the rip fence by lifting the lock down handle.
Unlock the bevel locking lever.
Adjust the bevel angle to the desired setting.
Lock the bevel locking lever.
Set the saw blade to the correct depth.
Loosen the lock knob on the miter gauge, set the miter
gauge to the desired angle and tighten lock knob.
Turn the power switch to the on ( ) position.
Position the workpiece flat on the table with the edge flush
against the miter gauge. Let the blade build up to full speed
before feeding the workpiece into the blade.
Advance the workpiece and the miter gauge toward the
blade. Keep the workpiece flush against the miter gauge.
Push the miter gauge and workpiece toward the blade.
Stand slightly to the side of the wood as it contacts the
blade to reduce the chance of injury should kickback occur.
When the cut is made, turn the saw off ( ). Wait for the
blade to come to a complete stop before removing the
workpiece.
After the blade has stopped completely, remove the cutoff
stock.
TO MAKE NON-THROUGH CUTS
Non-through cuts can be made with the grain (ripping) or
across the grain (crosscut). The use of a non-through cut is
essential to cutting grooves, rabbets, and dadoes. This is the
only type cut that is made without the blade guard installed.
Make sure the blade guard assembly is reinstalled upon
completion of this type of cut. Read the appropriate section
which describes the type of cut in addition to this section on
non-through or dado cuts. For example, if your non-through
cut is a straight cross cut, read and understand the section
on straight cross cuts before proceeding.

EXTENSION CORD CAUTION
When using a power tool at a considerable distance from a power
source, be sure to use an extension cord that has the capacity to
handle the current the tool will draw. An undersized cord will cause
a drop in line voltage, resulting in overheating and loss of power.
Use the chart to determine the minimum wire size required in an
extension cord. Only round jacketed cords should be used.
When working with a 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 any extension cord, inspect it for loose or exposed
wires and cut or worn insulation.
