GENERAL SAFETY RULES
WARNING:
Read and understand all instructions. Failure to follow all instructions listed below may result in electric shock, fire, and/or serious personal injury.
SAVE THESE INSTRUCTIONS
Work Area
■ Keep your work area clean and well lit. Cluttered benches and dark areas invite accidents.
■ Do not operate power tools in explosive atmospheres, such as in the presence of
flammable liquids, gases, or dust. Power tools create sparks which may ignite the dust or fumes.
■ Keep bystanders, children, and visitors away
while operating a power tool. Distractions can cause you to lose control.
Electrical Safety
■ Double insulated tools are equipped with a polarized plug (one blade is wider than the other). This 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 a polarized outlet. Do not change the plug in
any way. Double insulation eliminates the need for the three-wire grounded power cord and grounded power supply system.
■ Avoid body contact with grounded surfaces, such as pipes, radiators, ranges, and refrig-
erators. There is an increased risk of electric shock if your body is grounded.
■ Don’t expose power tools to rain or wet condi-
tions. Water entering a power tool will increase the risk of electric shock.
■ Do not abuse the cord. Never use the cord to carry the tools or pull the plug from an outlet.
Keep cord away from heat, oil, sharp edges, or moving parts. Replace damaged cords
immediately. Damaged cords increase the risk of electric shock.
■ When operating a power tool outside, use an outdoor extension cord marked “W-A” or “W.”
These cords are rated for outdoor use and reduce the risk of electric shock.
Personal Safety
■ Stay alert, watch what you are doing, and use common sense when operating a power tool.
Do not use tool while tired or under the influ-
ence of drugs, alcohol, or medication. A moment of inattention while operating power tools may result in serious personal injury.
■ 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.
■ Avoid accidental starting. Be sure switch is
off before plugging in. Carrying tools with your finger on the switch or plugging in tools that have the switch on invites accidents.

GENERAL SAFETY RULES
Personal Safety (continued)
■ 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.
■ Do not overreach. Keep proper footing and
balance at all times. Proper footing and balance enables better control of the tool in unexpected situations.
■ Use safety equipment. Always wear eye pro-
tection. Dust mask, nonskid safety shoes, hard hat, or hearing protection must be used for appropriate conditions.
Tool Use and Care
■ Use clamps or another practical way to secure and support the workpiece to a stable plat-
form. Holding the work by hand or against your body is unstable and may lead to loss of control.
■ 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.
■ Do not use tool if switch does not turn it on or
off. Any tool that cannot be controlled with the switch is dangerous and must be repaired.
■ Disconnect the plug from the power source before making any adjustments, changing
accessories, or storing the tool. Such preventive safety measures reduce the risk of starting the tool accidentally.
■ Store idle tools out of the reach of children
and other untrained persons. Tools are dangerous in the hands of untrained users.
■ Maintain tools with care. Keep cutting tools
sharp and clean. Properly maintained tools with sharp cutting edges are less likely to bind and are easier to control.
■ Check for misalignment or binding of moving parts, breakage of parts, and any other condi-
tion that may affect the tool's operation. If damaged, have the tool serviced before using.
Many accidents are caused by poorly maintained tools.
■ Use only accessories that are recommended
by the manufacturer for your model. Accessories that may be suitable for one tool, may become hazardous when used on another tool.
Service
■ Tool service must be performed only by
qualified repair personnel. Service or maintenance performed by unqualified personnel could result in a risk of injury.
■ When servicing a tool, use only identical replacement parts. Follow instructions in
Maintenance section of this manual. Use of unauthorized parts or failure to follow Maintenance Instructions may create a risk of electric shock or injury.
SPECIFIC SAFETY RULES
Specific Safety Rules for Circular Saws
■ 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.
■ 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.")
■ Do not reach underneath the work. The guard cannot protect you from the blade below the work.
■ 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
Page 3 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.
■ 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.
■ 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.
Specific Safety Rules for Circular Saws
(continued)
■ 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.
■ 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.
■ Hold tool by insulated gripping surface when performing an operation where the cutting tool may contact hidden wiring or its own cord.
Contact with a "live" wire will also make exposed metal parts of the tool "live" and shock the operator.
■ 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.
■ 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.
■ Never use damaged or incorrect blade washers
or bolts. The blade washers and bolts were specially designed for your 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.
SPECIFIC SAFETY RULES
■ 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:
■ 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.
■ 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.
■ 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.
■ 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.
■ Do not use dull or damaged blade. Unsharpened or improperly set blades produce narrow kerf which causes excessive friction, blade binding and
KICKBACK.
■ 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.
■ 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.

Additional Rules for Safe Operation
■ Know your power tool. Read operator's manual carefully. 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.
■ 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.
■ 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.
■ Protect your hearing. Wear hearing protection
during extended periods of operation. Following this rule will reduce the risk of serious personal injury.
■ Don't abuse cord. Never carry the tool by the cord or yank it to disconnect it from the receptacle. Keep cord away from heat, oil, and sharp
edges. Following this rule will reduce the risk of electric shock or fire.
■ 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 16 is recommended for an extension cord 100 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.
■ Inspect tool cords periodically and, if damaged, have repaired at your nearest Factory Service
Center or other Authorized Service Organization. Constantly stay aware of cord location.
Following this rule will reduce the risk of electric shock or fire.
■ 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 electric shock, fire or serious injury.
WARNING:
Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:
• lead from lead-based paints,
• crystalline silica from bricks and cement and other masonry products, and
• arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles.
The purpose of safety symbols is to attract your attention to possible dangers. The safety symbols, and the explanations with them, deserve your careful attention and understanding. The safety warnings do not by themselves eliminate any danger. The instructions or warnings they give are not substitutes for proper accident prevention measures.
SYMBOL MEANING

REMEMBER: Never use a blade that is too thick to allow the
"D" washer to engage with the flat on the spindle.
SAW BLADES
The best of saw blades will not cut efficiently if they are not kept clean, sharp, and properly set. Using a dull blade will place a heavy load on your saw and increase the danger of kickback. Keep extra blades on hand, so that sharp blades are always available.
Gum and wood pitch hardened on blades will slow your saw down. Remove saw blade from your saw and use gum and pitch remover, hot water, or kerosene to remove these accumulations. DO NOT USE GASOLINE.
BLADE GUARD SYSTEM
See Figure 4.
The lower blade guard attached to your circular saw is there for your protection and safety. It should never be altered for any reason. If it becomes damaged, do not operate your saw until the damage has been repaired or replaced. Always leave guard in operating position when using your saw.

OPERATION
WARNING:
Do not attempt to operate this tool until you have read thoroughly and understand completely all instructions, safety rules, etc., contained in this manual. Failure to comply can result in accidents involving fire, electric shock, or serious personal injury. Save operator's manual, and review frequently for continuing safe operation and for instructing others who may use this tool.
KICKBACK
See Figure 5.
THE BEST GUARD AGAINST KICKBACK IS TO AVOID
DANGEROUS PRACTICES.
Kickback occurs when the blade stalls rapidly and the saw is driven back toward you. Blade stalling is caused by any action which pinches the blade in the wood.
DANGER:
Release switch immediately if blade binds or saw stalls.
Kickback will cause you to lose control of your saw. Loss of control can lead to serious injury.
WRONG
Fig. 6
KICKBACK IS CAUSED BY:
■ Incorrect blade depth setting. See Figure 5.
■ Sawing into knots or nails in work.
■ Twisting blade while making a cut.
■ Making a cut with a dull, gummed up, or improperly set blade.
■ Incorrectly supporting work. See Figure 6.
■ Forcing a cut.
■ Cutting warped or wet lumber.
■ Tool misuse or incorrect operating procedures.
CORRECT BLADE DEPTH SETTING =
BLADE EXPOSED 1/4 in. OR
LESS ON UNDERSIDE OF WORKPIECE Fig. 7
TO LESSEN THE CHANCE OF KICKBACK:
■ Always keep the correct blade depth setting–the correct blade depth setting for all cuts should not exceed 1/4 in.
below the material to be cut. See Figure 7.
■ Inspect the work for knots or nails before beginning a cut. Never saw into a knot or nail.
■ Make straight cuts. Always use a straight edge guide when rip cutting. This helps prevent twisting the blade in the cut.
■ Always use clean, sharp, and properly set blades. Never make cuts with dull blades.
■ To avoid pinching the blade, support the work properly before beginning a cut. The right way to support large pieces of work are shown in Figure 8.
■ When making a cut, use steady, even pressure. Never force cuts.
■ Do not cut warped or wet lumber.
RIGHT Fig. 8
■ Always hold your saw firmly with both hands and keep your body in a balanced position so as to resist the forces of kickback should it occur.
WHEN USING YOUR SAW, ALWAYS STAY ALERT AND
EXERCISE CONTROL. DO NOT REMOVE YOUR SAW
FROM WORKPIECE WHILE THE BLADE IS MOVING.

OPERATION
DEPTH OF CUT ADJUSTMENT
Always keep correct blade depth setting. The correct blade depth setting for all cuts should not exceed 1/4 in. below the material to be cut. More blade depth will increase the chance of kickback and cause the cut to be rough.
TO ADJUST BLADE DEPTH
■ Unplug your saw.
WARNING:
Failure to unplug your saw could result in accidental starting causing possible serious personal injury.
■ Loosen depth adjustment knob. See Figure 9.
■ Hold base flat against the work and raise or lower saw until the required depth is reached.
■ Tighten depth adjustment knob securely.

OPERATION
TO CROSS CUT OR RIP CUT
See Figure 15.
When making a cross cut or rip cut, align your line of cut with the outer blade guide notch on the saw base (as shown in Figure 15) and view the blade through the viewing window.
Since blade thicknesses vary, always make a trial cut in scrap material along a guideline to determine how much, if any, the guideline must be offset to produce an accurate cut.
NOTE: The distance from the line of cut to the guideline is the amount you should offset the guideline.
OPTIONAL RIP GUIDE (EDGE GUIDE)
See Figure 16.
Use a guide when making long or wide rip cuts with your saw. An optional rip guide with a 5 in. scale is available, or you can make an efficient rip guide by clamping a straight edge to your workpiece. Secure the workpiece. Using Cclamps, firmly clamp a straight edge to the workpiece and guide the saw along the straight edge to achieve a straight rip cut. Do not bind the blade in the cut. If using the optional rip guide, see the following instructions and Figure 17.

TO BEVEL CUT
See Figure 18 and 19.
The angle of cut of your saw may be adjusted to any desired setting between zero and 51.5 degrees. There is a window in the saw base to help you line up the blade with the line of cut. See Figure 18. Align your line of cut with the inner blade guide notch on the saw base and view through the window when making full 45 degree bevel cuts. Since blade thicknesses vary and different angles require different settings, always make a trial cut in scrap material along a guideline to determine how much you should offset the guideline on the board to be cut.
When making a bevel cut, hold your saw firmly with both hands (as shown in Figure 19). Rest the front edge of the base on the work. Depress the switch trigger. ALWAYS let the blade reach full speed, then guide your saw into the work.

Attempting to make cuts without bevel adjustment knob securely tightened can result in serious injury.
LENGTH OF CUT SCALE
See Figure 21.
A length of cut scale has been provided on the base of your saw. It is parrallel with the saw blade and can be used to measure the distance into material the blade has cut.
NOTE: Six inches is the maximum length of the cut that can be measured. Also, it is accurate only when the depth of cut is set at full maximum depth.

OPERATION
DUST NOZZLE (MODEL CSB 130JS)
See Figure 22.
A dust nozzle is included with saw Model CSB130JS. As shown in figure 22, the dust nozzle fits over the dust chute which is located on the rear of the upper blade guard.
Attach dust nozzle with a twisting motion. The easy rotation of the dust nozzle allows the operator to direct the flow of dust and chips. The dust and chip opening should always be turned away from the operator.
TO POCKET CUT
See Figure 23.
WARNING:
Always adjust bevel setting to zero before making a pocket cut. Attempting a pocket cut at any other setting can result in loss of control of your saw possibly causing serious injury.
Adjust the bevel setting to zero, set blade to correct blade depth setting, and swing the lower blade guard up using the lower blade guard handle. ALWAYS RAISE THE LOWER
BLADE GUARD WITH THE HANDLE TO AVOID SERIOUS
INJURY. While holding lower blade guard by the handle, firmly rest the front of the base flat against the workpiece with the rear of the handle raised so the blade does not touch the work. See Figure 23. Depress the switch trigger.
ALWAYS LET THE BLADE REACH FULL SPEED, THEN
SLOWLY LOWER BLADE INTO THE WORK UNTIL BASE
IS FLAT AGAINST WORK. After you complete your cut, release the trigger and allow the blade to come to a complete stop. After the blade has stopped, remove it from the work.
Then, corners may be cleared out with a hand saw or sabre saw.
WARNING:
Never tie the lower blade guard in a raised position.
Leaving the blade exposed could lead to serious injury.

MAINTENANCE
WARNING:
When servicing use only identical Ryobi replacement parts. Use of any other parts 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.
When electric tools are used on fiberglass boats, sports cars, wallboard, spackling compounds, or plaster, it has been found that they are subject to accelerated wear and possible premature failure, as the fiberglass chips and grindings are highly abrasive to bearings, brushes, commutators, etc. Consequently, it is not recommended that this tool be used for extended work on any fiberglass material, wallboard, spackling compounds, or plaster. During any use on fiberglass it is extremely important that the tool is cleaned frequently by blowing with an air jet.
WARNING:
Do not at any time let brake fluids, gasoline, petroleumbased products, penetrating oils, etc. come in contact with plastic parts. They contain chemicals that can damage, weaken, or destroy plastic.
WARNING:
Always wear safety goggles or safety glasses with side shields during power tool operation or when blowing dust.
If operation is dusty, also wear a dust mask.
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.
DOUBLE INSULATION
Double insulation is a concept in safety in electric power tools, which eliminates the need for the usual three-wire grounded power cord. All exposed metal parts are isolated from the internal metal motor components with protecting insulation. Double insulated tools do not need to be grounded.
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 AUTHORIZED
SERVICE CENTER for repair.

Model CSB120, CSB130, or CSB130JS
DOUBLE INSULATED
EXTENSION CORD CAUTION
When using a power tool at a considerable distance from a power source, be sure to use an extension cord that has the capacity to handle the current the tool will draw. An undersized cord will cause a drop in line voltage, resulting in overheating and loss of power. Use the chart to determine the minimum wire size required in an extension cord. Only round jacketed cords should be used.
When working with a tool outdoors, use an extension cord that is designed for outside use. This is indicated by the letters "WA" on the cord's jacket.
Before using any extension cord, inspect it for loose or exposed wires and cut or worn insulation.
