ure to follow all instructions listed below, may result in
electric shock, fire and/or serious personal injury.
SAVE THESE INSTRUCTIONS
WORK AREA
n Keep your work area clean and well lit. Cluttered
benches and dark areas invite accidents.
n Do not operate power tools in explosive atmo-
spheres, such as in the presence of flammable
liquids, gases, or dust. Power tools create sparks which
may ignite the dust or fumes.
n Keep bystanders, children, and visitors away while
operating a power tool. Distractions can cause you to
lose control.
ELECTRICAL SAFETY
n A battery operated tool with integral batteries or a
separate battery pack must be recharged only with
the specified charger for the battery. A charger that
may be suitable for one type of battery may create a risk
of fire when used with another battery.
n Use battery operated tool only with specifically
designated battery pack. Use of any other batteries may
create a risk of fire.
n Use battery only with charger listed.

n Do not abuse the cord. Never use the cord to carry the
charger. Keep cord away from heat, oil, sharp edges,
or moving parts. Replace damaged cords immediately.
Damaged cords may create a fire.
PERSONAL SAFETY
n Stay ale rt, wat ch what you are doing and use
common sense when operating a power tool. Do not
use tool while tired or under the influence of drugs,
alcohol, or medication. A moment of inattention while
operating power tools may result in serious personal
injury.
n Dress properly. Do not wear loose clothing or jewelry.
Contain long hair. Keep your hair, clothing, and gloves
away from moving parts. Loose clothes, jewelry, or long
hair can be caught in moving parts.
n 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.
n Remove adjusting keys or wrenches before turning
the tool on. A wrench or a key that is left attached to a
rotating part of the tool may result in personal injury.
n Do not overreach. Keep proper footing and balance
at all times. Proper footing and balance enable better
control of the tool in unexpected situations.
n Use safety equipment. Always wear eye protection.
Dust mask, non-skid safety shoes, hard hat, or hearing
protection must be used for appropriate conditions.
n Do not wear loose clothing or jewelry. Contain long
hair. Loose clothes, jewelry, or long hair can be drawn
into air vents.
n Do not use on a ladder or unstable support. Stable
footing on a solid surface enables better control of the
tool in unexpected situations.
TOOL USE AND CARE
n Use clamps or other practical way to secure and sup-
port the workpiece to a stable platform. Holding the
work by hand or against your body is unstable and may
lead to loss of control.
n Do not force tool. Use the correct tool for your
application. The correct tool will do the job better and
safer at the rate for which it is designed.
n Do not use tool if switch does not turn it on or off.
A tool that cannot be controlled with the switch is
dangerous and must be repaired.
n Disconnect battery pack from tool or place the switch
in the locked or off position before making any adjustments, changing accessories, or storing the tool. Such
preventive safety measures reduce the risk of starting the
tool accidentally.
n Store idle tools out of reach of children and other
untrained persons. Tools are dangerous in the hands
of untrained users.
n When battery pack is not in use, keep it away from
other metal objects like: paper clips, coins, keys, nails,
screws, or other small metal objects that can make
a connection from one terminal to another. Shorting
the battery terminals together may cause sparks, burns,
or a fire.
n Maintain tools with care. Keep cutting tools sharp
and clean. Properly maintained tools wi th sharp
cutting edges are less likely to bind and are easier to
control.
n Check for misalignment or binding of moving parts,
breakage of parts, and any other condition that may
affect the tool’s operation. If damaged, have the tool
serviced before using. Many accidents are caused by
poorly maintained tools.
n Use only accessories that are recommended by the
manufacturer for your model. Accessories that may be
suitable for one tool may create a risk of injury when used
on another tool.
n Keep the tool and its handle dry, clean and free from
oil and grease. Always use a clean cloth when clean-
ing. Never use brake fluids, gasoline, petroleum-based
products, or any strong solvents to clean your tool. Following this rule will reduce the risk of loss of control and
deterioration of the enclosure plastic.
GENERAL SAFETY RULES
SERVICE
n Tool service must be performed only by qualified re-
pair personnel. Service or maintenance performed by
unqualified personnel may result in a risk of injury.
SPECIFIC SAFETY RULES
n DANGER! Keep hands away from cutting area and
blade. Keep your second hand on the auxiliary handle
or motor housing. If both hands are holding the saw,
they cannot be cut by the blade.
n Keep your body positioned to either side of the saw
blade, but not in line with the saw blade. KICKBACK
could cause the saw to jump backwards. (See “Causes
And Operator Prevention Of Kickback” later.)
n Do not reach underneath the work. The guard cannot
protect you from the blade below the work.
n Check lower guard for proper closing before each use.
Do not operate saw if lower guard does not move freely
and close instantly. Never clamp or tie the lower guard
into the open position. If saw is accidentally dropped,
lower guard may be bent. Raise the lower guard with the
retracting handle. Make sure it moves freely and does
not touch the blade or any other part, in all angles and
depths of cut.
n Check the operation and condition of the lower guard
spring. If the guard and the spring are not operating
properly, they must be serviced before use. Lower guard
may operate sluggishly due to damaged parts, gummy
deposits, or a buildup of debris.
n Lower guard should be retracted manually only for
special cuts, such as "Pocket Cuts" and "Compound
Cuts." Raise lower guard by retracting handle. As soon
as blade enters the material, lower guard must be
released. For all other sawing, the lower guard should
operate automatically.
n Always observe that the lower guard is covering the
blade before placing saw down on bench or floor. An
unprotected, coasting blade will cause the saw to walk
backwards, cutting whatever is in its path. Be aware of
the time it takes for the blade to stop after switch is
released.
n NEVER hold piece being cut in your hands or across
your leg. It is important to support the work properly
to minimize body exposure, blade binding, or loss of
control.
n Hold tool by insulated gripping surfaces when
performing an operation where the cutting tool may
contact hidden wiring or its own cord. Contact with a
“live” wire will make exposed metal parts of the tool “live”
and shock the operator.
n When servicing a tool, use only identical replacement
parts. Follow instructions in the Maintenance section
of this manual. Use of unauthorized parts or failure to fol-
low Maintenance Instructions may create a risk of shock
or injury.
n When ripping, always use a rip fence or straight edge
guide. This improves the accuracy of the cut and reduces
the chance for blade binding.
n Always use blades with correct size and shape
(diamond vs. round) arbor holes. Blades that do
not match the mounting hardware of the saw will run
eccentrically, causing loss of control.
n Never use damaged or incorrect blade washers
or bolts. The blade washers and bolts were specially
designed for the saw for optimum performance and safety
of operation.
Causes and Operator Prevention of Kickback:
Kickback is a sudden reaction to a pinched, bound, or
misaligned saw blade, causing an uncontrolled saw to lift up
and out of the workpiece toward the operator.
When the blade is pinched or bound tightly by the kerf closing
down, the blade stalls and the motor reaction drives the unit
rapidly back toward the operator.
If the blade becomes twisted or misaligned in the cut, the teeth
at the back edge of the blade can dig into the top surface of
the wood causing the blade to climb out of the kerf and jump
back toward the operator.
Kickback is the result of tool misuse and/or incorrect operating
procedures or conditions and can be avoided by taking proper
precautions, as given below:
n Maintain a firm grip with both hands on the saw and
position your body and arm to allow you to resist
KICKBACK forces. KICKBACK forces can be controlled
by the operator, if proper precautions are taken.
n When blade is binding, or when interrupting a cut
for any reason, release the trigger and hold the saw
motionless in the material until the blade comes to a
complete stop. Never attempt to remove the saw from
the work or pull the saw backward while the blade is
in motion, or KICKBACK may occur. Investigate and
take corrective actions to eliminate the cause of blade
binding.
n When restarting a saw in the workpiece, center the
saw blade in the kerf and check that saw teeth are
not engaged into the material. If saw blade is binding,
it may walk up or KICKBACK from the workpiece as the
saw is restarted.

SPECIFIC SAFETY RULES
n Support large panels to minimize the risk of blade
pinching and KICKBACK. Large panels tend to sag
under their own weight. Supports must be placed under
the panel on both sides, near the line of cut and near the
edge of the panel.
n Do not use dull or damaged blade. Unsharpened or
improperly set blades produce narrow kerf which causes
excessive friction, blade binding and KICKBACK.
n Blade depth and bevel adjusting locking levers
must be tight and secure before making cut. If blade
adjustment shifts while cutting, it may cause binding and
KICKBACK.
n Use extra caution when making a “Pocket Cut” into
existing walls or other blind areas. The protruding blade
may cut objects that can cause KICKBACK.
n Know your power tool. Read operator’s manual care-
fully. Learn its applications and limitations, as well
as the specific potential hazards related to this tool.
Following this rule will reduce the risk of electric shock,
fire, or serious injury.
n Always wear safety glasses. Everyday eyeglasses
have only impact-resistant lenses; they are NOT
safety glasses. Following this rule will reduce the risk
of serious personal injury.
n Protect your lungs. Wear a face or dust mask if the
operation is dusty. Following this rule will reduce the
risk of serious personal injury.
n Protect your hearing. Wear hearing protection during
extended periods of operation. Following this rule will
reduce the risk of serious personal injury.
n Inspect tool cords periodically and, if damaged, have
repaired at your nearest authorized service center.
Constantly stay aware of cord location. Following this
rule will reduce the risk of electric shock or fire.
n 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 should be properly repaired or replaced
by an authorized service center. Following this rule will
reduce the risk of shock, fire, or serious injury.
n 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. A wire gage size (A.W.G.) of at least 12 is
recommended for an extension cord 50 feet or
less in length. A cord exceeding 100 feet is not
recommended. If in doubt, use the next heavier gage.
The smaller the gage number, the heavier the cord. An
undersized cord will cause a drop in line voltage resulting
in loss of power and overheating.
n Inspect for and remove all nails from lumber before
using this tool. Following this rule will reduce the risk of
serious personal injury.
Laser Guide Warnings:
The laser guide radiation used in the Ryobi circular saw
is Class II with maximum <1mW and 650nm wavelengths.
These lasers do not normally present an optical hazard
although staring at the beam may cause flash blindness.
n Avoid direct eye exposure when using the laser guide.
n The laser shall be used and maintained in accordance
with the manufacturer’s instructions.
n Never aim the beam at a person or object other than the
workpiece.
n Always ensure the laser beam is aimed at a sturdy
workpiece without reflective surfaces. Shiny reflective
sheet metal or similar shiny materials are not suitable for
laser use.
n All repairs should be made by an authorized service
representative or the laser manufacturer.
n Save these instructions. Refer to them frequently and
use them to instruct others who may use this tool. If you
loan someone this tool, loan them these instructions
also.
