RULES FOR SAFE OPERATION
The purpose of safety rules is to attract your attention to
possible dangers. The safety symbols and the explanations with
them, require your careful attention and understanding.
The safety warnings by themselves do not elimimate any danger.
The instruction or warnings they give are not substitutes for
proper accident prevention measures.
SAFETY ALERT SYMBOL Indicates caution or
warning. May be used in conjunction with
other symbols or pictures.
WARNING: Failure to obey a safety warning
can result in serious injury to yourself or to
others. Always follow the safety precautions to
reduce the risk of fire, electric shock and
personal injury.
DOUBLE INSULATION
Double insulation is a concept in safety in electric power tools,
which eliminates the need for earth grounding. Whenever
there is electric current in the tool there are two complete sets
of insulation to protect the user. All exposed metal parts are
isolated from the internal metal motor components with
protecting insulation.
WARNING: The double insulated system is intended to protect
the user from shock resulting from a break in the tool's internal
wiring. Observe all normal safety precautions related to avoiding
electrical shock.
IMPORTANT: Servicing of a tool with double insulation requires
extreme care and knowledge of the system and should be
performed only by a qualified service technician. For service we
suggest you return the tool to your nearest Ryobi Authorised
Service Centre for repair. When servicing, use only identical
Ryobi replacement parts.

WARNING: When servicing, use only identical Ryobi
replacement parts. Use of any other part may create a
hazard or cause product damage.
■ GENERAL
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, carbon dust, etc.
It has been found that electric tools are subject to accelerated
wear and possible premature failure when they are used on
fibreglass boats, sports cars, wallboard, spackling compounds,
or plaster. The chips and grinding from these materials are
highly abrasive to electric tool pars such as bearings, brushes,
commutators, etc. Consequently, it is not recommended that
this tool be used for extended work on any fibreglass
material, wallboard, spackling compounds, or plaster. During
any use on these materials it is extremely important that the
tool is cleaned frequently by blowing with an air jet.
■ 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.
■ EXTENSION CORDS
The use of any extension cord will cause some loss of power.
To keep power loss to a minimum and to prevent tool
overheating, use an extension cord that is heavy enough to
carry the current the tool will draw.
A wire gauge size (A.W.G.) of at least 16 is recommended for
an extension cord 50 feet or less in length. When working
outdoors, use an extension cord that is suitable for outdoor
use.
If the supply cord is damaged, it shall be replaced by the
manufacturer or its service agent in order to avoid a hazard.
Disconnect from the supply immediately, if the supply cable is
damaged.
Take care not to expose this tool to rain.
WARNING: Do not at any time let brake fluids,
gasoline, petroleum based products,
penetrating oils, etc. come into contact with
plastic parts. They contain chemicals that can
daamage, weaken or destroy plastic.
CAUTION: Keep extension cords away from the
cutting area and position the cord so that it will
not get caught on timber, tools, etc. during
cutting operation.
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.
WARNING: Always wear safety goggles or
safety glasses with side sheilds during power
tool operation or when blowing dust.
If operation is dusty, also wear a dust mask.

■ SELF-RETRACTING LOWER BLADE GUARD
The lower blade guard provides protection from each side of
the blade. It retracts over the upper blade guard as the saw is
lowered into the workpiece.
■ ELECTRICAL CONNECTION
Your saw has a precision built electric motor. It should be
connected to a power supply that is 240 volts AC, 50-60 Hz,
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 your tool does not
operate when plugged into an outlet, double-check the power
supply.
WARNING: Failure to unplug your CMS812
could result in accidental starting causing
possible serious personal injury.

WARNING: The operation of any power tool can
result in foreign objects being thrown into your
eyes, which can result in severe eye damage.
Before beginning power tool operation, always
wear safety goggles or safety glasses with side
shields and a full face shield when needed. We
recommend a Wide Vision Safety Mask for use
over eyeglasses or standard safety glasses with
side shields
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
hazardous condition leading to possible serious
personal injury.
ADJUSTMENTS
■ REPLACING BLADE (Fig 5)
1. Unscrew the two screws holding the lower guard retraction
arm and remove the retraction arm. (Fig 5)
2. Unscrew the two phillips headed screws holding the lower
perspex guard and remove the guard. (Fig 5)
3. Place a piece of scrap timber under the blade and pull the
saw arm head down until the teeth of the blade lock into the
scrap timber. This will then allow you to unscrew the blade
bolt. Remove the outer flange and blade.
WARNING: To prevent accidental starting that
could cause possible serious personal injury,
assemble all parts to your saw before
connecting it to the power supply. Saw should
never be connected to power supply when you
are assembling parts, making adjustments,
installing or removing blades, or when not in
use.
DANGER: A 210 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 screw from securing the blade on the
spindle. Either of these situations will result in a
serious accident and can cause personal injury.
WARNING: Failure to unplug your saw could
result in accidental starting causing possible
serious personal injury.
WARNING: If the 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.

when the saw arm is moved to the 45° bevel position the allen
screw bottoms out. Check 45° angle with a 45° set square
(Fig 19) from the table to the blade. If the table and blade do
not align, readjust the 45° positioning screw (Fig 20) so that it
bottoms out at 45° and realign the bevel indication pointer
correctly (Fig 21)
■ APPLICATIONS
(Use only for the purposes listed below)
• Cross Cutting wood & plastics
• Cross Cutting mitres, joints, etc. for picture frames,
moldings, door casings and fine joinery.
NOTE: The crosscut blade provided is for most wood cutting
operations. For fine joinery and picture frame cuts or cutting
plastic, use a blade suitable, available from your nearest
hardware store.
■ CUTTING WITH YOUR COMPOUND MITRE
SAW
■ CROSSCUTTING
A crosscut is made by cutting across the grain of the
workpiece. A 90° crosscut is made with the mitre table set at
the zero degree position. Mitre crosscuts are made with the
mitre table set at some other angle other than zero.
■ TO CROSSCUT WITH YOUR MITRE SAW
• Pull out the lock pin and lift the saw arm to its full
height.
• Unlock the mitre table.
• Rotate the mitre table until the pointer aligns with
the desired angle on the mitre scale.
• Lock the mitre table handle.
NOTE: You can quickly locate 5° increments left or right on the
scale. The mitre table can be seated in one of the positive stop
notches, located in the mitre table frame.
• Place the workpiece flat on the mitre table with one edge
securely against the fence. If the board is warped, place the
convex side against the fence and clamp. 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. (Fig 22)
Fig.19
Fig.20
Fig.21
WARNING: Before starting any cutting
operations, clamp or bolt your compound mitre
saw to a workbench. Never operate your mitre
saw on the floor or in a crouched position.
Failure to heed this warning can result in serious
personal injury
OPERATIONS
WARNING: Use a clamp to secure your
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 blade will
cause motor stalling and kickback. This
situation could cause an accident resulting in
serious personal injury.
Fig.22

Page 10
• When cutting long pieces of timber or molding, support the
opposite end of the stock.
• 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.
• Before turning on the saw, perform a dry run of the cutting
operation just to make sure that no problems will occur
when the cut is made.
• Grasp the saw handle firmly, then squeeze the switch
trigger. Allow several seconds for the blade to reach
maximum speed.
• Slowly lower the blade into and through the workpiece.
• Release the switch trigger and allow the saw blade to stop
rotating before raising the blade out of the workpiece.
■ BEVEL CUT
A bevel cut is made by cutting across the grain of the
workpiece with the blade angled to the fence and mitre table.
A bevel cut is made with the mitre table set at zero degree
position and the blade set at an angle between 0° and 45°
(Fig 23)
■ TO BEVEL CUT WITH YOUR MITRE SAW
• Pull out the lock pin and lift the saw arm to its full height.
• Loosen the mitre table locking knobs.
• Rotate the mitre table until the pointer aligns with zero on
the mitre scale.
• Lock the mitre table by securing the two mitre table lock
knobs.
• Loosen the bevel lock handle and move the saw arm to the
left to the desired bevel angle.
• 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 handle.
• Place the workpiece flat on the mitre table with one warped,
place the convex against the fence. If the board is warped,
place the convex side against the fence. If the concave edge
of the board is placed against the fence, the board could co
lapse on the blade at the end of the cut, jamming the blade.
• When cutting long pieces of timber or molding, support the
overhanging end(s) of the stock.
• Align the cutting line on the workpiece with the edge of saw
blade.
• Grasp the stock firmly with one hand and secure it against
the fence.
• Before turning on the saw, perform a dry run of the cutting
operation just to make sure that no problems will occur
when the cut is made.
• Grasp the saw handle firmly, then squeeze the switch
trigger. Allow several seconds for the blade to reach
maximum speed.
• Slowly lower the blade into and through the workpiece.
• Release the switch trigger and allow the saw blade to stop
rotating before raising the blade out of workpiece.
■ COMPOUND MITRE CUT
A compound mitre cut is a cut made using a mitre angle and a
bevel angle at the same time. This type of cut is used to make
picture frames, cut moulding, make boxes with sloping sides,
and for certain roof framing cuts.
To make this type of cut the mitre 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 mitre setups due to the interaction of the two angle
settings.
Adjustments of mitre and bevel settings are interdependent
with one another. Each time you adjust the mitre setting you
change the effect of the bevel setting. Also, each time you
adjust the bevel setting you change the effect of the mitre
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 wood before making
a finish cut in good wood. (Fig 24)
WARNING: To avoid serious personal injury
keep your hands outside the no hands zone; at
least 75mm from blade. Never perform any
cutting operation freehand (without holding
workpiece against the fence). The blade could
grab the workpiece if it slips or twists
WARNING: To avoid serious personal injury,
always push the mitre table clamp back down
before making a cut. Failure to do so could
result in movement of the mitre table while
making a cut causing serious personal injury.
WARNING: To avoid serious personal injury,
keep your hands outside the no hands zone; at
least 75mm from the blade. Never perform any
cutting operation free-hand (without holding
workpiece against the fence). The blade could
grab the workpiece if it slips or twists.
Fig.23

■ TO MAKE A COMPOUND CUT WITH YOUR
MITRE SAW
• Pull out the lock pin and lift the saw arm to its full height.
• Loosen the mitre table locking knobs.
• Rotate the mitre table until the pointer aligns with the
desired angle on the mitre scale and lock both mitre table
lock knobs.
NOTE: You can quickly locate 5° increments left or right on the
scale. The mitre table can be seated in one of the positive stop
notches, located in the mitre table frame.
• Loosen the bevel lock handle and move the saw arm to the
left to the desired bevel angle.
• 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 handle.
• Recheck mitre angle setting. Make a test cut in scrap
material
• Place the workpiece flat on the mitre 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 the
board is placed against the fence, the board could collapse
on the blade at the end of the cut, jamming the blade.
(Fig 25).
• When cutting long pieces of timber or molding, support the
opposite end of the stock with a roller stand or with work
surface level with the saw table.
• Align the cutting line on the workpiece with the edge of the
saw blade.
• Grasp the stock firmly with one hand and secure it against
the fence.
• Before turning on the saw, perform a dry run of the cutting
operation just to make sure that no problems will occur
when the cut is made.
• Grasp the saw handle firmly, then squeeze the switch
trigger. Allow several seconds for blade to reach maximum
speed.
• Slowly lower the blade into and through the workpiece.
• Release the switch trigger and allow the saw blade to stop
rotating before raising the blade out of workpiece.

■ CUTTING CROWN MOLDING
Your compound mitre saw does an excellent job of cutting
crown molding. In general, compound mitre saws do a better
job of cutting crown molding than any other tool made.
In order to fit properly, crown molding must be compound
mitred 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 MITRE
TABLE
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 mitre table and against the fence.
When setting the bevel and mitre angles for compound
mitres, 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 a scrap
molding. Also most walls do not have angles of exactly 90°,
therefore, you will need to finetune your settings.

Page 13
When cutting crown molding by this method the bevel angle
should be set at 33.85°. The mitre 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 mitre table.
The settings in the chart below can be used for cutting all
standard crown moulding with 52° and 38° angles. The crown
moulding is placed flat on the mitre table using the compound
features of your mitre saw.

When cutting warped material, always make sure it is
positioned on the mitre table with the convex side against the
fence as shown in figure 26.
If the warped material is positioned the wrong way as shown
in figure 27, it will pinch the blade near the completion of the
cut.
