Page 3 SPECIFIC SAFETY RULES Hold tool by insulated gripping surfaces when performing an operation where the cutting tool may contact hidden wiring. Contact with a "live" wire will make exposed metal parts of the tool "live" and shock the operator. Additional Rules For Safe Operation Additional Specific Safety Rules ■ ■ ■ 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. 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. ■ ■ ■ Important Rules For Battery Tools ■ ■ 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. Do not place battery tools or their batteries near fire or heat. This will reduce the risk of explosion and possible injury. ■ ■ WARNING: Batteries vent hydrogen gas and can explode in the presence of 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, flush with water immediately. ■ ■ ■ Do not charge battery tool in a damp or wet location. Following this rule will reduce the risk of electric shock, fire, or serious personal injury. Your battery tool should be charged in a location where the temperature is more than 50°F but less than 100°F. Following this rule will reduce the risk of electric shock, fire, or serious personal injury. 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 into your eyes, flush them with clean water for at least 10 minutes, then seek immediate medical attention. Following this rule will reduce the risk of serious personal injury. ■ ■ ■ ■ ■ Page 4 DANGER! Keep hands away from cutting area and blade. Keep your second hand on 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. Do not reach underneath the work. The guard cannot protect you from the blade below the work. Check the 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 and 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. 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 insulating gripping surfaces when performing an operation where the cutting tool may contact hidden wiring. 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 for a straight edge guide. This improves the accuracy of cut and reduces the chance of 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. SPECIFIC SAFETY RULES 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 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 causing 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 will 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 Specific Safety Rules Continued ■ ■ ■ ■ Never use damaged or incorrect blade washers or bolts. The blade washers and bolt 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. Kickback is a 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 on the saw and position your body and arm in a way that allows 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 ■ ■ ■ ■ ■ IMPORTANT SAFETY INSTRUCTIONS FOR CHARGER WARNING: CAUTION: Never use a battery that has been dropped or received a sharp blow.

BLADE WRENCH Fig. 6 LOWER BLADE GUARD IS IN UP POSITION WHEN MAKING A CUT 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. Use gum and pitch remover, hot water, or kerosene to remove these accumulations. DO NOT USE GASOLINE. BLADE GUARD SYSTEM The lower blade guard attached to your cordless circular saw is there for your protection and safety. It should never be altered for any reason. If it becomes damaged or begins to return slow or sluggish, do not operate your saw until the damage has been repaired or replaced. Always leave guard in operating position when using saw. DANGER: When sawing through workpiece, lower blade guard does not cover blade on the underside of workpiece. Since blade is exposed on underside of workpiece, keep hands and fingers away from cutting area. Any part of your body coming in contact with moving blade will result in serious injury. See Figure 7. BLADE EXPOSED ON UNDERSIDE OF WORKPIECE Fig. 7 Never use saw when guard is not operating correctly. Guard should be checked for correct operation before each use. If you drop your saw, check the lower blade guard and bumper for damage at all depth settings before reuse. NOTE: The guard is operating correctly when it moves freely and readily returns to the closed position. If for any reason your lower blade guard does not close freely, take it to the nearest Ryobi authorized service center for service before using. Page 11 OPERATION KICKBACK See Figure 8. The best guard against kickback is to avoid dangerous practices. Kickback occurs when the blade stalls rapidly and the saw is driven back towards you. Blade stalling is caused by any action which pinches the blade in the wood. KICKBACK WARNING: BLADE SET TOO DEEP Fig. 8 To avoid kickback, release switch immediately if blade binds or saw stalls. Kickback could cause you to lose control of your saw. Loss of control can lead to serious injury. KICKBACK IS CAUSED BY: ■ ■ ■ ■ Incorrect blade depth setting. See Figure 8. Sawing into knots or nails in workpiece. Twisting blade while making a cut. Making a cut with a dull, gummed up, or improperly set blade. Incorrectly supporting workpiece. See Figure 9. Forcing a cut. Cutting warped or wet lumber. Tool misuse or incorrect operating procedures. 50 ■ ■ ■ ■ 45 30 22.5 15 0 WRONG Fig. 9 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 10. One blade tooth below the material to be cut works best for most efficient cutting action. ■ Inspect the workpiece 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 workpiece properly before beginning a cut. The right and wrong ways to support large pieces of work are shown in figures 9 and 11. CORRECT BLADE DEPTH SETTING = BLADE EXPOSED ONE BLADE TOOTH BELOW THE MATERIAL TO BE CUT Fig. 10 50 5 4 30 22.5 15 0 RIGHT Page 12 Fig. 11 OPERATION ■ When making a cut use steady, even pressure. Never force cuts. ■ Do not cut warped or wet lumber. ■ 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. DEPTH OF CUT ADJUSTMENT Always keep correct blade depth setting. The correct blade depth setting for all cuts should not exceed 1/4 inch (6.4 mm) below the material to be cut. More blade depth will increase the chance of kickback and cause the cut to be rough. One blade tooth below the material to be cut works best for most efficient cutting action. BASE ASSEMBLY TO ADJUST BLADE DEPTH ■ Remove battery pack from saw. DEPTH ADJUSTMENT KNOB Fig. 12 WARNING: Failure to remove battery pack from saw could result in accidental starting causing possible serious personal injury. 50 45 0 3 2 2 ■ Loosen depth adjustment knob. See Figure 12. ■ Hold base flat against the workpiece and raise or lower saw until the required depth is reached. ■ Tighten depth adjustment knob securely. STARTING A CUT Know the right way to use your saw. See Figure 13. Never use your saw as shown in figure 14. RIGHT Fig. 13 WRONG Fig. 14 Never place your hand on the workpiece behind your saw while making a cut. WARNING: 30 2 2 Page 13 50 45 To make sawing easier and safer, always maintain proper control of your saw. Loss of control of your saw could cause an accident resulting in possible serious injury. OPERATION TO HELP MAINTAIN CONTROL: ■ Always support your workpiece near the cut. ■ Support your workpiece so the cut will be on your left. ■ Clamp your workpiece so it will not move during the cut. 3 2 0 2 50 45 Place your workpiece with its good side down. NOTE: The good side is the side on which appearance is important. Before beginning a cut, draw a guideline along the desired line of cut. Then place front edge of base on that part of your workpiece that is solidly supported. See Figure 16. Never place your saw on that part of the workpiece that will fall off when the cut is made. See Figure 15. Hold your saw firmly with both hands. See Figure 16. Depress the lock-off button and squeeze the switch trigger to start your saw. Always let the blade reach full speed, then guide your saw into the workpiece. WARNING: WRONG Fig. 15 The blade coming in contact with the workpiece before it reaches full speed could cause your saw to "kickback" towards you resulting in serious injury. When making a cut use steady, even pressure. Forcing causes rough cuts, could shorten the life of your saw and could cause "kickback." DANGER: 50 45 0 3 2 2 When sawing through work, the lower blade guard does not cover the blade, exposing it on the underside of work. Keep your hands and fingers away from cutting area. Any part of your body coming in contact with the moving blade will result in serious injury. After you complete your cut release the trigger and allow the blade to come to a complete stop. Do not remove your saw from workpiece while the blade is moving. WARNING: To make sawing easier and safer, always maintain proper control of your saw. Loss of control of your saw could cause an accident resulting in possible serious injury. Page 14 RIGHT Fig. 16 OPERATION TO CROSS CUT OR RIP CUT TOP VIEW OF SAW 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 17. GUIDELINE FRONT OF SAW 1 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. 0 45 1 2 3 4 WIDTH OF CUT SCALE See Figure 18. A width of cut scale has been provided on the base of your saw. When making straight cross cuts or rip cuts, the scale can be used to measure up to four inches to the right side of the blade. It can be used to measure up to one inch to the left side of the blade.

NOTE: When making cuts at 50°, blade should be set at full depth of cut. When making 45° bevel cuts, there is a notch in the saw base to help you line up the blade with the line of cut. See Figure 19. Align your line of cut with the inner blade guide notch on the saw base when making 45° 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 20. Rest the front edge of the base on the workpiece. Depress the lock-off button and squeeze the switch trigger to start your saw. Always let the blade reach full speed, then guide your saw into the workpiece.

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 Fig. 22 handle raised so the blade does not touch the workpiece. See Figure 22. Depress the lock-off button and squeeze the switch trigger to start your saw. Always let the blade reach full speed then slowly lower blade into the workpiece until base is flat against workpiece. 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 workpiece. Corners may then 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. Page 17 OPERATION TO RIP CUT STRAIGHT EDGE 3 2 0 2 50 45 OPTIONAL RIP GUIDE (EDGE GUIDE) See Figure 23. Use a guide when making long or wide rip cuts with your saw. An optional rip guide with a five inch scale is available or you can make an efficient rip guide by clamping a straight edge to your workpiece. Secure the workpiece. Using C-clamps, 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 24. TO ASSEMBLE OPTIONAL RIP GUIDE See Figure 24. ■ Remove battery pack from saw. C-CLAMPS WARNING: Failure to remove battery pack from saw could result in accidental starting causing possible serious personal injury. WORKPIECE ALTERNATE METHOD FOR RIP CUTTING ■ Place rip guide through holes in saw base as shown in figure 24. ■ Adjust rip guide to the width needed. Fig. 23 ■ Tighten rip guide screw (wing screw) securely. When using a rip guide, position the face of the rip guide firmly against the edge of workpiece. This makes for a true cut without pinching the blade. The guiding edge of workpiece must be straight for your cut to be straight. Use caution to prevent the blade from binding in the cut.
