RULES FOR SAFE OPERATION

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 good working
order.

■ REMOVE ADJUSTING KEYS AND
WRENCHES. Get in the habit of checking to see

that hex keys and adjusting wrenches are
removed from tool before turning on saw.

■ KEEP THE WORK AREA CLEAN. Cluttered
work areas and work benches invite accidents.
DO NOT leave tools or pieces of wood on the
saw while it is in operation.

■ DO NOT USE IN DANGEROUS ENVIRON­MENTS. Do not use power tools near gasoline or

other flammable liquids, 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 while operating.

■ MAKE WORKSHOP CHILD-PROOF with
padlocks and master switches, or by removing
starter keys.

■ DO NOT 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
attachment to do a job it was not designed for.
Don't use it for a purpose not intended.

■ USE THE PROPER EXTENSION CORD FOR
CHARGER. 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 16 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.

■ PERIODICALLY INSPECT EXTENSION
CORDS and replace if damaged.

■ DRESS PROPERLY. Do not wear loose clothing,

gloves, neckties, rings, bracelets, or other jewelry.
They 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-resistant lenses; they are NOT safety
glasses.

■ 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.

■ SECURE WORK. Use clamps or a vise to hold
work when practical. It's safer than using your
hand and it frees both hands to operate tool.

■ DO NOT 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 ALL TOOLS. When not in use,
before servicing, or when changing attachments,
blades, bits, cutters, etc., all tools should be
disconnected or battery pack removed.

■ AVOID ACCIDENTAL STARTING. Be sure
switch is in the locked or off position before
inserting battery pack. Carrying tools with your
finger on the switch or inserting the battery pack
into a tool with the switch on invites accidents.

■ USE RECOMMENDED ACCESSORIES. The use
of improper accessories may cause risk of injury.
Refer to this operator's manual for recommended
accessories.

■ NEVER STAND ON TOOL. Serious injury could
occur if the tool is tipped or if the blade 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.

RULES FOR SAFE OPERATION

■ NEVER LEAVE TOOL RUNNING UNAT­TENDED. REMOVE BATTERY PACK. Do not

leave tool, move workpiece or make adjustments
until it comes to a complete stop.

■ FIRMLY CLAMP OR BOLT your miter saw to a
workbench or table at approximately hip height.

■ USE ONLY CORRECT BLADES. Do not use
blades with incorrect size holes. Never use blade
washers or blade bolts that are defective or
incorrect. The maximum blade capacity of your
saw is 8-1/4 in. (209.6 mm).

■ KEEP BLADES CLEAN, SHARP AND WITH
SUFFICIENT SET. Sharp blades minimize

stalling and kickback.

■ DO NOT REMOVE THE SAW'S BLADE
GUARDS. Never operate the saw with any guard

or cover removed. Make sure all guards are
operating properly before each use.

■ KEEP HANDS AWAY FROM CUTTING AREA.

Keep hands away from blades. Do not reach
underneath work or around or under the blade
while blade is rotating. Do not attempt to remove
cut material when blade is moving.

■ BLADE COASTS AFTER TURN OFF.

■ DO NOT ABUSE CHARGER CORD. Never yank

cord to disconnect it from receptacle. Keep cord
from heat, oil, and sharp edges.

■ INSPECT CHARGER CORD PERIODICALLY

and if damaged, have repaired at your nearest
authorized service center.

■ DO NOT USE TOOL IF SWITCH DOES NOT
TURN IT ON AND OFF. Have defective switches

replaced by an authorized service center.

■ 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.

■ ALWAYS SUPPORT LONG WORKPIECES to
minimize risk of blade pinching and kickback.
Saw may slip, walk, or slide while cutting long or
heavy boards.

■ BEFORE MAKING A CUT, BE SURE ALL
ADJUSTMENTS ARE SECURE.

■ AVOID CUTTING NAILS. Inspect for and
remove all nails from lumber before cutting.

■ ALWAYS USE A CLAMP to secure the work-
piece when possible.

■ NEVER TOUCH BLADE or other moving parts
during use.

■ NEVER START A TOOL WHEN THE BLADE IS
IN CONTACT WITH WORKPIECE. Allow motor
to come up to full speed before starting cut.

■ MAKE SURE THE MITER TABLE AND SAW
ARM (BEVEL FUNCTION) ARE LOCKED IN
POSITION BEFORE OPERATING YOUR SAW.

Lock the miter table by securely tightening the
miter lock handle. Lock the saw arm (bevel
function) by securely tightening the bevel lock
knob.

■ NEVER USE A LENGTH STOP ON THE FREE
SCRAP END OF A CLAMPED WORKPIECE.
NEVER hold onto or bind the free scrap end of

the workpiece in any operation. If a work clamp
and length stop are used together, they must
both be installed on the same side of the saw
table to prevent the saw from catching the loose
end and kicking up.

■ NEVER cut more than one piece at a time. DO
NOT STACK more than one workpiece on the

saw table at a time.

■ NEVER PERFORM ANY OPERATION "FREE­HAND". Always place the workpiece to be cut on

the miter table and position it firmly against and
parallel to the fence as a backstop. Always use
the fence.

■ NEVER hand hold a workpiece that is too small
to be clamped. Keep hands clear of the no hands
zone.

■ NEVER reach behind, under, or within three
inches (76 mm) of the blade and its cutting path
with your hands and fingers for any reason.

■ NEVER reach to pick up a workpiece, a piece of
scrap, or anything else that is in or near the
cutting path of the blade.

■ AVOID AWKWARD OPERATIONS AND HAND
POSITIONS where a sudden slip could cause

your hand to move into the blade. ALWAYS
make sure you have good balance. NEVER
operate your miter saw on the floor or in a
crouched position.

■ NEVER stand or have any part of your body in
line with the path of the saw blade.

■ ALWAYS release the power switch and allow the
saw blade to stop rotating before raising it out of
the workpiece.

■ DO NOT TURN THE MOTOR SWITCH ON AND
OFF RAPIDLY. This could cause the saw blade

to loosen and could create a hazard. Should this
ever occur, stand clear and allow the saw blade
to come to a complete stop. Disconnect your saw
from the power supply and securely retighten the
blade bolt.

RULES FOR SAFE OPERATION

■ REPLACEMENT PARTS. All repairs, whether

electrical or mechanical, should be made at your
nearest authorized service center.

■ When servicing use only identical Ryobi replace­ment parts. Use of any other parts may create a
hazard or cause product damage.

■ NEVER USE IN AN EXPLOSIVE ATMO­SPHERE. Normal sparking of the motor could

ignite fumes.

■ NEVER leave the miter saw unattended while
connected to a power source.

■ POLARIZED PLUGS. To reduce the risk of
electric shock, this charger has a polarized plug
(one blade is wider than the other). This charger
plug will fit in a polarized outlet only one way. If
the plug does not fit fully in the outlet, reverse
the plug. If it still does not fit, contact a qualified
electrician to install the proper outlet. Do not
change the plug in any way.

■ IF ANY PART OF THIS MITER SAW IS MISS­ING or should break, bend, or fail in any way, or

should any electrical component fail to perform
properly, release switch trigger, remove the
battery pack and have damaged, missing, or
failed parts replaced before resuming operation.

■ DO NOT OPERATE THIS TOOL WHILE UN­DER THE INFLUENCE OF DRUGS, ALCOHOL,
OR ANY MEDICATION.

■ ALWAYS STAY ALERT! Do not allow familiarity
(gained from frequent use of your saw) to cause
a careless mistake. ALWAYS REMEMBER that
a careless fraction of a second is sufficient to
inflict severe injury.

■ 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.

■ MAKE SURE THE WORK AREA HAS AMPLE
LIGHTING to see the work and that no obstruc-

tions will interfere with safe operation BEFORE
performing any work using your saw.

IMPORTANT SAFETY RULES FOR BATTERY
TOOLS

■ Battery tools do not have to be plugged into an
electrical outlet; therefore, they are always in
operating condition. Be aware of possible
hazards when not using your battery tool or
when changing accessories.

■ Remove battery pack from tool or make sure
the switch is in the lock-off position before
making any adjustments, changing
accessories, storing the tool or when not in
use. Such preventive safety measures reduce

the risk of starting the tool accidentally.

■ When battery pack is not in use, keep it away
from metal objects like paper clips, coins,
keys, nails, screws, other small metal objects
as well as necklaces, chains, rings etc. that
can make a connection from one terminal to
another. Shorting the battery terminals together

may cause sparks, burns, or a fire.

■ Use battery operated tool only with
specifically designated battery pack. Use of

any other batteries may create a risk of fire. Use
only the battery pack listed.

■ USE ONLY THE CHARGER PROVIDED WITH
YOUR BATTERY TOOL. Do not substitute any

other charger. Use of another charger could
cause batteries to explode causing possible
serious injury.

■ DO NOT PLACE BATTERY TOOLS OR THEIR
BATTERIES NEAR FIRE OR HEAT. Batteries

vent hydrogen gas and can explode in the
presence of heat or a source of ignition, such as
a pilot light. To reduce the risk of serious
personal injury, never use any cordless product in
the presence of open flame. An exploded battery
can propel debris and chemicals. If exposed,
wash immediately with soap and water and
neutralize with lemon juice or vinegar.

■ DO NOT CHARGE BATTERY TOOL IN A
DAMP OR WET LOCATION.

■ Your battery tool should be charged in a location
where the temperature is more than 50°F (10°C)
but less than 100°F (37°C).

■ Under extreme usage or temperature conditions,
battery leakage may occur. If liquid comes in
contact with your skin, wash immediately with
soap and water, then neutralize with lemon juice
or vinegar. If liquid gets in your eyes, flush them
with clean water for at least 10 minutes, then
seek immediate medical attention.

■ If carrying your battery tool at your side, make
sure it is not running and your finger is not on the
switch. Avoid accidental starting.

■ WHEN SERVICING USE ONLY IDENTICAL
RYOBI REPLACEMENT PARTS.

WARNING:

To prevent accidental starting that could cause
possible serious personal injury, assemble all parts
to your saw before attaching battery pack. Battery
pack should never be attached to saw when you
are assembling parts, making adjustments,
installing or removing blades, or when not in use.

As mentioned previously your saw has been factory
assembled and adjusted. The dust guide or dust bag,
battery pack and blade are the only parts that have to
be installed.

DUST GUIDE

See Figure 12.

■ Remove battery pack from saw.

squeeze the two metal clips to open the mouth of the
bag and slide it on the exhaust port. Release the clips.
The metal ring in the bag should lock in one of the
grooves on the exhaust port. For more efficient
operation, empty dust bag when no more than half
full. This will permit better air flow through the bag.

DANGER:

A 8-1/4 in. (209.6 mm) blade is the maximum blade
capacity of your saw. Never use a blade that is too
thick to allow outer blade washer to engage with
the flats on the spindle. Larger blades will come in
contact with the blade guards, while thicker blades
will prevent the blade bolt from securing the blade
on the spindle. Either of these situations will result
in a serious accident and can cause serious
personal injury.

■ Remove battery pack from saw.

WARNING:

Failure to remove battery pack from your saw could
result in accidental starting causing possible serious
personal injury.

■ Push down on the saw arm and pull out the lock
pin to release saw arm. Raise saw arm to its full
raised position. Be cautious, saw arm is spring
loaded to raise.

■ Loosen the phillips screw on the blade bolt
cover until blade bolt cover can be raised.

PIVOT ADJUSTMENTS

Note: These adjustments were made at the factory

and normally do not require readjustment.

TRAVEL PIVOT ADJUSTMENT

■ The saw arm should rise completely to the up
position by itself.

■ If the saw arm does not raise by itself or if there is
play in the pivot joints, have saw repaired at your
nearest RYOBI AUTHORIZED SERVICE CEN-

TER.

BEVEL PIVOT ADJUSTMENT

■ Your compound miter saw should bevel easily by
loosening bevel lock knob and tilting saw arm to
the left.

■ If movement is tight or if there is play in the pivot,
have saw repaired at your nearest RYOBI

AUTHORIZED SERVICE CENTER.

DEPTH STOP

The depth stop limits the blade's downward travel. It
allows the blade to go below the miter table enough to
maintain full cutting capacities. The depth stop
positions the blade 1/4 in. (6.4 mm) from the miter
table support.

Note: The miter table support is located inside miter
table.

The depth stop is factory set to provide maximum
cutting capacity for the 8-1/4 in. (209.6 mm) saw
blade provided with your saw. Therefore, the saw
blade provided should never need adjustments.

However, when the diameter of the blade has been
reduced due to sharpening, it may be necessary to
adjust the depth stop to provide maximum cutting
capacity. Also, when a new blade is installed, it is
necessary to check the clearance of the blade to the
miter table support before starting the saw. Make
adjustments if needed.

DEPTH STOP ADJUSTMENTS

See Figure 31.

■ Remove battery pack from saw.

■ Use the 5 mm hex key provided to adjust the

depth stop adjustment screw. The saw blade is
lowered by turning the screw counterclockwise
and raised by turning the screw clockwise.

OPERATION

CUTTING WITH YOUR COMPOUND
MITER SAW

WARNING:

When using a work clamp or C-clamp to secure
your workpiece, clamp workpiece on one side of
the blade only. The workpiece must remain free on
one side of the blade to prevent the blade from
binding in workpiece. The workpiece binding the
blade will cause motor stalling and kickback. This
situation could cause an accident resulting in
possible serious personal injury.

CROSSCUTTING

See Figure 33.

A crosscut is made by cutting across the grain of the
workpiece. A 90° crosscut is made with the miter table
set at the zero degree position. Miter crosscuts are
made with the miter table set at some angle other
than zero.

Note: You can quickly locate 0°, 22-1/2° left or
right, 30° left or right, and 45° left or right on the
scale. The miter table can be seated in one of the
detent stop notches, located in the miter table
frame.

WARNING:

To avoid serious personal injury, always push the
miter table clamp back down before making a cut.
Failure to do so could result in movement of the
miter table while making a cut.

■ Place the workpiece flat on the miter table with
one edge securely against the fence. If the board
is warped, place the convex side against the
fence. If the concave edge of a board is placed
against the fence, the board could collapse on the
blade at the end of the cut, jamming the blade.

See Figures 40 and 41.

■ When cutting long pieces of lumber or molding,
support the opposite end of the stock with a roller
stand or with a work surface level with the saw
table.

■ Align cutting line on the workpiece with the edge
of saw blade.

■ Grasp the stock firmly with one hand and secure
it against the fence. Use the work clamp or a C­clamp to secure the workpiece when possible.

OPERATION

COMPOUND MITER CUT

See Figures 36 and 37.

A compound miter cut is a cut made using a miter
angle and a bevel angle at the same time. This type of
cut is used to make picture frames, cut molding, make
boxes with sloping sides, and for certain roof framing
cuts.

To make this type of cut the miter table must be
rotated to the correct angle and the saw arm must be
tilted to the correct bevel angle. Care should always
be taken when making compound miter setups due to
the interaction of the two angle settings.

Adjustments of miter and bevel settings are interde­pendent with one another. Each time you adjust the
miter setting you change the effect of the bevel
setting. Also, each time you adjust the bevel setting
you change the effect of the miter setting.

It may take several settings to obtain the desired cut.
The first angle setting should be checked after setting
the second angle, since adjusting the second angle
affects the first.

Once the two correct settings for a particular cut have
been obtained, always make a test cut in scrap
material before making a finish cut in good material.

OPERATION

CUTTING CROWN MOLDING

Your compound miter saw does an excellent job of
cutting crown molding. In general, compound miter
saws do a better job of cutting crown molding than
any other tool made.

In order to fit properly, crown molding must be com­pound mitered with extreme accuracy.

The two contact surfaces on a piece of crown molding
that fit flat against the ceiling and the wall of a room
are at angles that, when added together, equal
exactly 90°. Most crown molding has a top rear angle
(the section that fits flat against the ceiling) of 52° and
a bottom rear angle (the section that fits flat against
the wall) of 38°.

52°

38°

CEILING

LAYING MOLDING FLAT ON THE
MITER TABLE

See Figure 39.

To use this method for accurately cutting crown
molding for a 90° inside or outside corner, lay the
molding with its broad back surface flat on the miter
table and against the fence.

When setting the bevel and miter angles for com­pound miters, remember that the settings are interde­pendent; changing one angle changes the other angle
as well.

Keep in mind that the angles for crown moldings are
very precise and difficult to set. Since it is very easy
for these angles to shift, all settings should first be
tested on scrap molding. Also, most walls do not have
angles of exactly 90°, therefore, you will need to fine
tune your settings.

When cutting crown molding by this method the bevel
angle should be set at 33.85°. The miter angle should
be set at 31.62° either right or left, depending on the
desired cut for the application. See the chart below for
correct angle settings and correct positioning of crown
molding on miter table.

The settings in the chart below can be used for cutting
All Standard (U.S.) crown molding with 52° and 38°
angles. The crown molding is placed flat on the miter
table using the compound features of your miter saw.

MAINTENANCE

WARNING:

When servicing, use only identical Ryobi
replacement parts. Use of any other part may
create a hazard, cause product damage or create
a risk of serious personal injury.

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. They contain
chemicals that can damage, weaken or destroy
plastic and create a risk of serious personal injury.

Do not abuse power tools. Abusive practices can
damage tool as well as workpiece.

WARNING:

Do not attempt to modify this tool or create
accessories not recommended for use with this
tool. Any such alteration or modification is misuse
and could result in a hazardous condition leading
to possible serious personal injury.

service technician. For service we suggest you return
the tool to your nearest RYOBI AUTHORIZED
SERVICE CENTER for repair. Always use original
factory replacement parts when servicing.

BATTERIES

The battery pack for this saw is equipped with 15
nickel-cadmium rechargeable battery cells. Length of
service from each charging will depend on the type of
work you are doing.

The battery cells have been designed to provide
maximum trouble free life. However, like all batteries,
they will eventually wear out. Do not disassemble
battery pack and attempt to replace the battery cells.
Handling of these batteries, especially when wearing
rings and jewelry, could result in a serious burn and
possible explosion.

To obtain the longest possible battery life, we suggest
the following:

■ Store and charge your battery pack in a cool area.
Temperatures above or below normal room
temperature will shorten battery life.

■ Never store battery pack in a discharged
condition. Recharge them immediately after they
are discharged.

■ All batteries gradually lose their charge. The
higher the temperature the quicker they lose their
charge. If you store your tool for long periods of
time without using it, recharge the batteries every
month or two. This practice will prolong battery
life.

To preserve natural resources, please
recycle or dispose of batteries
properly.

This product contains nickel­cadmium batteries. Local, state or
federal laws may prohibit disposal of
nickel-cadmium batteries in ordinary

trash.
Consult your local waste authority for information
regarding available recycling and/or disposal options.

BATTERY PACK REMOVAL AND
PREPARATION FOR RECYCLING

WARNING:

Upon removal, cover the battery pack's terminals
with heavy duty adhesive tape. Do not attempt to
destroy or disassemble battery pack or remove any
of its components. Nickel-cadmium batteries must
be recycled or disposed of properly. Also, never
touch both terminals with metal objects and/or
body parts as short circuit may result. Keep away
from children. Failure to comply with these
warnings could result in fire and/or serious injury.
