AND SOME PLASTICS ONLY. DO NOT CUT METALS,
CERAMICS OR MASONRY PRODUCTS.
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 the fence as a backstop.
Always use the fence.
4
SPECIFIC SAFETY RULES

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.
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, shut off
the power switch, remove the miter saw plug from the
power source and have damaged, missing, or failed parts
replaced before resuming operation.
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.
MAKE SURE THE WORK AREA HAS AMPLE LIGHTING
to see the work and that no obstructions will interfere with
safe operation BEFORE performing any work using your
saw.

ASSEMBLY
WORK CLAMP
See Figure 10.
The work clamp provides greater control by clamping the
workpiece to the fence. It also prevents the workpiece from
creeping toward the saw blade. This is very helpful when
cutting compound miters.
Depending on the cutting operation and the size of the
workpiece, it may be necessary to use a C-clamp instead
of the work clamp to secure the workpiece prior to making
the cut.
WARNING:
In some operations, the work clamp assembly may
interfere with the operation of the blade guard assembly.
Always make sure there is no interference with the blade
guard prior to beginning any cutting operation to reduce
the risk of serious personal injury.
To install the work clamp:
Place the shaft of the work clamp in either hole on the
saw table base.
Rotate the knob on the work clamp to move it in or out
as needed.

TO INSTALL/REPLACE THE BLADE
See Figures 11 - 12.
WARNING:
A 7-1/4 in. blade is the maximum blade capacity of the
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
could result in a serious accident and can cause serious
personal injury.
Remove the battery pack from the tool.
Raise the saw arm.
Rotate lower blade guard up and remove blade bolt cover
screw. Rotate blade bolt cover up and back to expose
the blade bolt.
Depress the spindle lock button and rotate the blade bolt
until the spindle locks.
Using the wrench provided, loosen and remove the blade
bolt.
NOTE: The blade bolt has left hand threads. Turn blade
bolt clockwise to loosen.
Remove outer blade washer. Do not remove inner blade
washer.
Wipe a drop of oil onto inner blade washer and outer
blade washer where they contact the blade.
WARNING:
If inner blade washer has been removed, replace it before
placing blade on spindle. Failure to do so could cause an
accident since blade will not tighten properly.

DANGER:
Laser radiation. Avoid direct eye contact with light source.
WARNING:
Use of controls or adjustments or performance of procedures other than those specified herein may result in
hazardous radiation exposure.
ALIGNING THE LASER GUIDE LINE
See Figure 24.
Draw a line on the workpiece. When the laser guide switch
is turned on it will generate a red line on the work surface.
This line will let you see your mark and the laser guide line
at the same time, and will assist you in lining up the mark
for more accurate cutting of the workpiece.
Align the laser line and the mark with the blade at the
uppermost position. Once both lines are in alignment, do
not move the workpiece.
Make several practice cuts on different styles and thickness
of material. Repeat the steps above as necessary.
Follow the directions below for using the laser guide.
Removing your mark:
Position the laser line near the left edge of your mark on the
work surface in order to remove the mark.
To cut your mark:
Position the laser line near or over your mark on the work
surface in order to cut the mark.
To leave your mark:
Position the laser line near the right edge of your mark on
the work surface in order to leave the mark.
After you have become familiar with using the laser guide,
you will be able to remove, cut, or leave your mark on the
work surface. Practice will teach you the correct position
for aligning the laser line with your mark.

TO COMPOUND MITER CUT
See Figures 30 - 31.
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, and make boxes with
sloping sides.
To make this type of cut the control arm on 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.
Pull out the lock pin and lift saw arm to its full height.
Lift the miter lock lever.
Rotate the miter table until the pointer aligns with zero
on the miter scale.
NOTE: You can quickly locate 0°, 15°, 22-1/2°, left or right,
31.62° and 45° left or right as you rotate the control arm.
The miter table will seat itself in one of the positive stop
index points, located in base.
Push the miter lock lever down to lock the miter table.
Loosen the bevel lock knob and move the saw arm to
the left to the desired bevel angle.
Bevel angles can be set from 0° to 45°.
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.

OPERATION
CUTTING CROWN MOLDING
This 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°.
LAYING MOLDING FLAT ON THE MITER
TABLE
See Figure 33.
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.

ceiLing
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 molding 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 for correct angle settings and
correct positioning of crown molding on miter table.
The settings in the chart 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 the miter saw.

CUTTING WARPED MATERIAL
See Figures 34 - 35.
When cutting warped material, always make sure it is positioned on the miter table with the convex side against the
fence as shown in figure 34.
If the warped material is positioned the wrong way as shown
infigure 35, it will pinch the blade near the completion of
the cut.
WARNING:
To avoid a kickback and to avoid serious personal injury,
never position the concave edge of bowed or warped
material against the fence.

ADJUSTMENTS
WARNING:
To prevent accidental starting that could cause serious
personal injury, always remove the battery pack from the
tool when assembling parts.
The compound miter saw has been adjusted at the
factory for making very accurate cuts. However, some of
the components might have been jarred out of alignment
during shipping. Also, over a period of time, readjustment
will probably become necessary due to wear. After unpacking
the saw, check the following adjustments before you begin
using the saw. Make any readjustments that are necessary
and periodically check the parts alignment to make sure that
the saw is cutting accurately.
CAUTION:
Do not start the compound miter saw without checking
for interference between the blade and the throat plate.
Damage could result to the blade if it strikes the throat
plate during operation of the saw.
POSITIVE STOP ADJUSTMENTS
See Figure 36.
NOTE: These adjustments were made at the factory and
normally do not require readjustment.
To adjust:
Remove the battery pack from the tool.
Loosen the bevel lock knob by turning the knob
counterclockwise.
Square the blade to the miter table as described in the
Assembly section of this manual.
If the blade is out of square, adjust by tightening or
NOTE: The above procedure can be used to check blade
squareness of the saw blade to the miter table at both 0°
and 45° angles.
The saw has two scale indicators, one on the bevel scale
and one on the miter scale. After squaring adjustments have
been made, it may be necessary to loosen the indicator
screws and reset them to zero.
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 by at your nearest
authorized service center.
BEVEL PIVOT ADJUSTMENT
The compound miter saw should bevel easily by loosening
the bevel lock knob and tilting the saw arm to the left.
If movement is tight or if there is play in the pivot, have saw
repaired by at your nearest authorized service center.

TO ADJUST THE LASER GUIDE
See Figure 37.
Set miter and bevel angles to 0º.
Use the work clamp or a C-clamp to secure a piece of
scrap wood.
Turn the saw on and make a slight cut to score the wood.
Release the switch trigger and allow the saw blade to
stop rotating before raising the saw arm.
Using a padlock, lock the switch trigger to make the saw
inoperable.
Turn on the laser switch.
To adjust the laser, loosen the laser adjustment screw
using the Phillips end of the supplied blade wrench.
Move the laser left or right until properly aligned.
NOTE: The laser should be on the left edge of the kerf.

NOTE: If laser does not align correctly, return to your nearest
Ryobi Authorized Service Center for repair.
TO ADJUST THE MITER LOCK LEVER
See Figure 38.
Prior to squaring the saw blade to the fence, check and
adjust the miter lock lever, if needed. In the “locked” position, the action of pushing the miter lock lever fully down
should feel tight and secure. Considerable effort should be
required to move the miter table. If the table moves easily
when in the “locked” position, an adjustment of the miter
lock lever is required.
To adjust:
Remove the battery pack from the tool.
Push the miter lock lever fully down to lock.
Pull the miter lock lever out to the right to disengage, then
pull forward to adjust.
