RULES FOR SAFE OPERATION  
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.  
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.  
ALWAYS WEAR SAFETY GLASSES WITH  
SIDE SHIELDS. Everyday eyeglasses have only  
impact-resistant lenses; they are NOT safety  
glasses.  
KEEP GUARDS IN PLACE and in good working  
order.  
PROTECT YOUR LUNGS. Wear a face or dust  
mask if the cutting operation is dusty.  
REMOVE ADJUSTING KEYS AND  
PROTECT YOUR HEARING. Wear hearing  
protection during extended periods of operation.  
WRENCHES. Get in the habit of checking to see  
that hex keys and adjusting wrenches are  
removed from tool before turning on saw.  
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.  
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 OVERREACH. Keep proper footing and  
balance at all times.  
DO NOT USE IN DANGEROUS ENVIRON-  
MENTS. Do not use power tools near gasoline or  
other flammable liquids, in damp or wet loca-  
tions, or expose them to rain. Keep the work  
area well lit.  
MAINTAIN TOOLS WITH CARE. Keep tools  
sharp and clean for better and safer perfor-  
mance. 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.  
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.  
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.  
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 RECOMMENDED ACCESSORIES. The use  
of improper accessories may cause risk of injury.  
Refer to this operator's manual for recommended  
accessories.  
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.  
NEVER STAND ON TOOL. Serious injury could  
occur if the tool is tipped or if the blade is unin-  
tentionally contacted.  
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.  
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.  
PERIODICALLY INSPECT EXTENSION  
CORDS and replace if damaged.

RULES FOR SAFE OPERATION  
NEVER LEAVE TOOL RUNNING UNAT-  
NEVER START A TOOL WHEN THE BLADE IS  
TENDED. REMOVE BATTERY PACK. Do not  
leave tool, move workpiece or make adjustments  
until it comes to a complete stop.  
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.  
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).  
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.  
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.  
NEVER cut more than one piece at a time. DO  
NOT STACK more than one workpiece on the  
saw table at a time.  
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.  
NEVER PERFORM ANY OPERATION "FREE-  
HAND". 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.  
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.  
NEVER hand hold a workpiece that is too small  
to be clamped. Keep hands clear of the no hands  
zone.  
INSPECT CHARGER CORD PERIODICALLY  
and if damaged, have repaired at your nearest  
authorized service center.  
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.  
DO NOT USE TOOL IF SWITCH DOES NOT  
TURN IT ON AND OFF. Have defective switches  
replaced by an authorized service center.  
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.  
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.  
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.  
ALWAYS SUPPORT LONG WORKPIECES to  
minimize risk of blade pinching and kickback.  
Saw may slip, walk, or slide while cutting long or  
heavy boards.  
NEVER stand or have any part of your body in  
line with the path of the saw blade.  
BEFORE MAKING A CUT, BE SURE ALL  
ADJUSTMENTS ARE SECURE.  
ALWAYS release the power switch and allow the  
saw blade to stop rotating before raising it out of  
the workpiece.  
AVOID CUTTING NAILS. Inspect for and  
remove all nails from lumber before cutting.  
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.  
ALWAYS USE A CLAMP to secure the work-  
piece when possible.  
NEVER TOUCH BLADE or other moving parts  
during use.

RULES FOR SAFE OPERATION  
REPLACEMENT PARTS. All repairs, whether  
electrical or mechanical, should be made at your  
nearest authorized service center.  
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 servicing use only identical Ryobi replace-  
ment parts. Use of any other parts may create a  
hazard or cause product damage.  
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.  
NEVER USE IN AN EXPLOSIVE ATMO-  
SPHERE. 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.  
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.  
IF ANY PART OF THIS MITER SAW IS MISS-  
ING 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 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 OPERATE THIS TOOL WHILE UN-  
DER 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.  
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).  
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.  
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.  
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  
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.  
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.  
WHEN SERVICING USE ONLY IDENTICAL  
RYOBI REPLACEMENT PARTS.

FEATURES  
Your compound miter saw should be permanently  
TRIGGER LOCK  
mounted to a firm supporting surface such as work-  
bench. Four 3/8 in. (10 mm) bolt holes have been  
provided in the saw base for this purpose. Each of the  
four mounting holes should be bolted securely using  
3/8 in. (10 mm) machine bolts, lock washers, and hex  
nuts (not included). Bolts should be of sufficient length  
to accommodate the saw base, lock washers, hex  
nuts, and the thickness of the workbench. Tighten all  
four bolts securely.  
See Figure 10.  
To prevent unauthorized use of your compound miter  
saw, we suggest that you remove battery pack and  
lock the switch in the off position. To lock the switch,  
install a padlock through the hole in the switch trigger.  
A lock with a shackle up to 13/64 in. (5.2 mm) diam-  
eter may be used. When the lock is installed and  
locked, the switch is inoperable. Store the padlock key  
in another location.  
The hole pattern for an 18-5/8 in. x 24 in. (457.2 mm x  
609.6 mm) workbench is shown in Figure 11. Care-  
fully check the workbench after mounting to make  
sure that no movement can occur during use. If any  
tipping, sliding, or walking is noted, secure the work-  
bench to the floor before operating.

SELF-RETRACTING LOWER BLADE GUARD  
WARNING:  
The lower blade guard is made of shock-resistant,  
see-through plastic that provides protection from each  
side of the blade. It retracts over the upper blade  
guard as the saw is lowered into the workpiece.  
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.

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.  
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.  
DUST BAG  
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.

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.

Your compound miter saw has been adjusted at the  
factory for making very accurate cuts. However, some  
of the components might have been bumped out of  
alignment during shipping. Also, over a period of time,  
readjustment will probably become necessary due to  
wear. After unpacking your saw, check the following  
adjustments before you begin using saw. Make any  
readjustments that are necessary and periodically  
check the parts alignment to make sure that your saw  
is cutting accurately.

DEPTH STOP  
MITER TABLE  
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.  
Fig. 31  
Lower the blade into the throat plate of the miter  
table. Check blade clearance and maximum  
cutting distance (distance from fence where blade  
enters) to front of miter table slot.  
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.  
Readjust if necessary.  
WARNING:  
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.  
Do not install battery pack or start your compound  
miter saw without checking for any interference  
with the blade. If the blade strikes any part of the  
table or frame, serious injury or damage to the saw  
could result.  
Tighten the hex nut with a 17 mm wrench or  
adjustable wrench.  
DEPTH STOP ADJUSTMENTS  
See Figure 31.  
To prevent the depth stop adjustment screw from  
turning while tightening the hex nut, carefully hold  
it with the hex key while tightening the hex nut.  
Remove battery pack from saw.  
WARNING:  
Failure to remove battery pack from your saw  
could result in accidental starting causing possible  
serious personal injury.

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:  
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.  
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.  
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.  
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 C-  
clamp to secure the workpiece when possible.

OPERATION  
COMPOUND MITER CUT  
See Figures 36 and 37.  
TO MAKE A COMPOUND CUT WITH YOUR  
MITER SAW:  
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.  
Pull out the lock pin and lift saw arm to its full height.  
Lift the miter table clamp.  
Rotate the miter table until the pointer aligns with  
the desired angle on the miter scale.  
Push the miter table clamp back down.  
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.  
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.  
Adjustments of miter and bevel settings are interde-  
pendent 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.  
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.  
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.  
Loosen the bevel lock knob and move the saw  
arm to the left to the desired bevel angle.  
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.  
Bevel angles can be set from 0° to 45°.  
Align the indicator point with the desired angle.  
Once the saw arm has been set at the desired  
angle, securely tighten the bevel lock knob.  
Recheck miter angle setting. Make a test cut in  
scrap material.  
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 41 and 42.

SUPPORT LONG WORKPIECES  
See Figure 38.  
Long workpieces need extra supports. Supports  
should be placed along the workpiece so it does not  
sag. The support should let the workpiece lay flat on  
the base of the saw and work table during the cutting  
operation. Use the work clamp or a C-clamp to secure  
the workpiece.

CUTTING CROWN MOLDING  
LAYING MOLDING FLAT ON THE  
MITER TABLE  
See Figure 39.  
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.  
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.  
In order to fit properly, crown molding must be com-  
pound mitered with extreme accuracy.  
When setting the bevel and miter angles for com-  
pound miters, remember that the settings are interde-  
pendent; changing one angle changes the other angle  
as well.  
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°.  
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.

OPERATION  
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.
