Page 3 RULES FOR SAFE OPERATION Safe operation of this power tool requires that you read and understand this operator's manual and all labels affixed to the tool. Safety is a combination of common sense, staying alert, and knowing how your miter saw works. ALWAYS WEAR SAFETY GLASSES WITH SIDE SHIELDS. Everyday eyeglasses have only impact-resistant lenses; they are NOT safety glasses. WEAR A DUST MASK to keep from inhaling fine particles. PROTECT YOUR HEARING. Wear hearing protection during extended periods of operation. SECURE WORK. Use clamps or a vise to hold work when practical. It's safer than using your hand and frees both hands to operate tool. DO NOT OVERREACH. Keep proper footing and balance at all times. MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for better and safer performance. Follow instructions for lubricating and changing accessories. DISCONNECT ALL TOOLS. When not in use, before servicing, or when changing attachments, all tools should be disconnected. AVOID ACCIDENTAL STARTING. Be sure switch is off when plugging in any tool. USE RECOMMENDED ACCESSORIES. Consult the operator's manual for recommended accessories. The use of improper accessories may case risk of injury. NEVER STAND ON TOOL. Serious injury could occur if the tool is tipped or if the blade is unintentionally contacted. CHECK DAMAGED PARTS. Before using 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 must be properly repaired or replaced by an authorized service center to avoid risk of personal injury. NEVER LEAVE TOOL RUNNING UNATTENDED, TURN THE POWER OFF. Do not leave tool until it comes to a complete stop. FIRMLY CLAMP OR BOLT your miter saw to a workbench or table at approximately hip height. USE ONLY CORRECT BLADES. Use the right blade size, style and cutting speed for material and type of cut. Do not use blades with incorrect size holes. Never use blade washers or blade bolts that are defective or incorrect. The maximum blade capacity of your saw is 12 in. KEEP BLADES CLEAN, SHARP, AND WITH SUFFICIENT SET. Sharp blades minimize stalling and kickback. DO NOT REMOVE THE SAW'S BLADE GUARDS. Never operate the saw with any guard or cover removed. Make sure all guards are operating properly before each use. KEEP HANDS AWAY FROM CUTTING AREA. Do not reach underneath work or in blade cutting path with hands and fingers for any reason. Always turn power off. READ ALL INSTRUCTIONS KNOW YOUR POWER TOOL. Read the operator's manual carefully. Learn the saw's applications and limitations as well as the specific potential hazards related to this tool. GUARD AGAINST ELECTRICAL SHOCK by preventing body contact with grounded surfaces such as pipes, radiators, ranges, refrigerator enclosures. KEEP GUARDS IN PLACE and in good working order. REMOVE WRENCHES AND ADJUSTING KEYS. Get in the habit - before turning on tool - that hex keys and adjusting wrenches are removed from tool. KEEP THE WORK AREA CLEAN. Cluttered work areas and work benches invite accidents. DO NOT leave tools or pieces of wood on the saw while it is in operation. DO NOT USE IN DANGEROUS ENVIRONMENTS. Do not use power tools near gasoline or other flammable liquids, in damp or wet locations, or expose them to rain. Keep the work area well lit. KEEP CHILDREN AND VISITORS AWAY. All visitors should wear safety glasses and be kept a safe distance from work area. Do not let visitors contact tool or extension cord while operating. MAKE WORKSHOP CHILDPROOF with padlocks and master switches or by removing starter keys. DO NOT FORCE THE TOOL it will do the job better and safer at the rate for which it was designed. USE THE RIGHT TOOL FOR THE JOB. Do not force the tool or attachment to do a job it was not designed for. Use it only the way it was intended. USE THE PROPER EXTENSION CORD. Make sure your extension cord is in good condition. Use only a cord heavy enough to carry the current your product will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. A wire gage size (A.W.G.) of at least 14 is recommended for an extension cord 25 feet or less in length. If in doubt, use the next heavier gage. The smaller the gage number, the heavier the cord. INSPECT TOOL CORDS AND EXTENSION CORDS PERIODICALLY and, if damaged, have repaired at your nearest authorized service center. Stay constantly aware of cord location and keep it well away from the moving blade. DRESS PROPERLY. Do not wear loose clothing, gloves, neckties, rings, bracelets, or other jewelry that can get caught and draw you into moving parts. Nonslip footwear is recommended. Also wear protective hair covering to contain long hair. Page 4 RULES FOR SAFE OPERATION BLADE COASTS AFTER BEING TURNED OFF. DO NOT ABUSE CORD. Never yank cord to disconnect it from receptacle. Keep cord from heat, oil, and sharp edges. USE ONLY OUTDOOR EXTENSION CORDS. Use only extension cords with the marking "Acceptable for use with outdoor appliances; store cords indoors while not in use". Use extension cords with an electrical rating not less than the saw's rating. Always disconnect the extension cord from the outlet before disconnecting the product from the extension cord. DO NOT USE TOOL IF SWITCH DOES NOT TURN IT ON AND OFF. Have defective switches replaced by an authorized service center. KEEP TOOL DRY, CLEAN, AND FREE FROM OIL AND GREASE. Always use a clean cloth when cleaning. Never use brake fluids, gasoline, petroleum-based products, or any solvents to clean tool. ALWAYS SUPPORT LONG WORKPIECES while cutting to minimize risk of blade pinching and kickback. Saw may slip, walk or slide while cutting long or heavy boards. BEFORE MAKING A CUT, be sure all adjustments are secure. BE SURE BLADE PATH IS FREE OF NAILS. Inspect for and remove all nails from lumber before cutting. NEVER TOUCH BLADE or other moving parts during use for any reason. BE SURE THE BLADE CLEARS THE WORKPIECE. Never start the saw with the blade touching the workpiece. Allow motor to come up to full speed before starting cut. MAKE SURE MITER TABLE AND SAW ARM (BEVEL FUNCTION) ARE LOCKED IN POSITION BEFORE OPERATING YOUR SAW. Lock the miter table by securely tightening the miter lock handle. Lock the saw arm (bevel function) by securely tightening the bevel lock knob. 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. NEVER reach behind, under, or within three inches of the blade and its cutting path with your hands and fingers for any reason. NEVER hand hold a workpiece that is too small to be clamped. Keep hands clear of the no hands zone. NEVER reach to pick up a workpiece, a piece of scrap, or anything else that is in or near the cutting path of the blade. 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. REPLACEMENT PARTS. All repairs, whether electrical or mechanical, should be made at your nearest authorized service center. WHEN SERVICING, use only identical Ryobi replacement parts. Use of any other parts may create a hazard or cause product damage. NEVER USE THIS TOOL IN AN EXPLOSIVE ATMOSPHERE. Normal sparking of the motor could ignite fumes. POLARIZED PLUGS. To reduce the risk of electric shock, this tool has 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 the proper outlet. Do not change the plug in any way. 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. DO NOT OPERATE THIS TOOL WHILE UNDER THE INFLUENCE OF DRUGS, ALCOHOL, OR ANY MEDICATION. 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 on a second is sufficient to inflict serious injury. Page 5 RULES FOR SAFE OPERATION STAY ALERT AND EXERCISE CONTROL. Watch what you are doing and use common sense. Do not operate tool when you are tired. Do not rush. 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. ALWAYS TURN OFF THE SAW before disconnecting it to avoid accidental starting when reconnecting to power supply. NEVER leave the saw unattended while connected to a power source. ALWAYS carry the saw only by the carrying handle. AVOID direct eye exposure when using the laser guide. SAVE THESE INSTRUCTIONS. Refer to them frequently and use them to instruct other users. If you loan someone this tool, loan them these instructions also. 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. SAVE THESE INSTRUCTIONS GLOSSARY OF TERMS FOR WOODWORKING Arbor The shaft on which a blade or cutting tool is mounted. Bevel Cut A cutting operation made with the blade at any angle other than 90° to the miter table. Compound Miter Cut A compound miter cut is a cut made using a miter angle and a bevel angle at the same time. Crosscut A cutting or shaping operation made across the grain of the workpiece. Freehand Performing a cut without using a fence, vise, fixture, work clamp, or other proper device to keep the workpiece from twisting or moving during the cut. Gum A sticky, sap based residue from wood products. Miter Cut A cutting operation made with the blade at any angle other than 90° to the fence. No Hands Zone Area between the marked lines on the left and right side of the miter table base. This zone is identified by no hands zone labels placed inside the marked lines on the miter table base. Resin A sticky, sap base substance that has hardened. Revolutions Per Minute (RPM) The number of turns completed by a spinning object in one minute. Saw Blade Path The area over, under, behind, or in front of the blade. As it applies to the workpiece, that area which will be, or has been, cut by the blade. Set The distance that the tip of the saw blade tooth is bent (or set) outward from the face of the blade. Through Sawing Any cutting operation where the blade extends completely through the thickness of the workpiece. Throw-Back Throwing of a workpiece in a manner similar to a kickback. Usually associated with a cause other than the kerf closing, such as a workpiece not being against the fence, being dropped into the blade, or being placed inadvertently in contact with the blade. Workpiece The item on which the cutting operation is being done. The surfaces of a workpiece are commonly referred to as faces, ends, and edges. Zero Clearance Throat Plate A plastic throat plate inserted in the miter table that allows for blade clearance. When you make your first cut with your compound miter saw, the saw blade cuts a slot through the throat plate the exact width of the blade. This provides for a zero clearance kerf that minimizes workpiece tear-out.

The work clamp provides greater control by clamping the workpiece to the fence or the saw table. 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. 2 1 1 2 1 2 Fig. 9 4 1 2 1 5 2 1 6 12 2 7 12 8 12 9 1 10 2 3 Follow these directions 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. 30 15 WARNING: When using any clamp with the stop block, install the clamp on the same side as the stop block. This will eliminate the possibility of trapping the workpiece, resulting in the saw blade and workpiece kicking up. Failure to heed this warning can result in serious personal injury. WORK CLAMP MITER TABLE BASE Fig. 10 Page 12 30 45 ASSEMBLY TABLE EXTENSIONS See Figures 11, 12, and 13. If you plan to use the stop block, slide the stop block on the back arm of the desired table extension first. To install table extensions, insert the ends of extensions into the holes in the sides of the base. See Figures 12 and 13. Adjust the extensions to the desired length. Secure them in place by positioning a clamp bracket under each table extension beneath the miter table. Orient each clamp bracket as shown in figure 13. Secure each clamp bracket in place with a clamp bracket screw. The clamp bracket screw threads through the clamp bracket and tightens against bracket support on bottom of miter table, securing clamp bracket against table extension.

After squaring adjustments have been made, it may be necessary to loosen the indicators screws and reset them to zero. See Figure 24. CORRECT VIEW OF BLADE SQUARE WITH MITER TABLE Page 18 ADJUSTMENTS BEVEL PIVOT ADJUSTMENT Your 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 RYOBI AUTHORIZED SERVICE CENTER. WARNING: POSITIVE STOP ADJUSTMENT SCREW FOR 0° ANGLES POSITIVE STOP ADJUSTMENT SCREW FOR 45° ANGLES Fig. 28 Do not start your compound miter saw without checking for interference between the blade and the miter table support. Damage could result to the blade if it strikes the miter table support during operation of the saw. LOCK NUT(S) APPLICATIONS (Use only for the purposes listed below) Cross cutting wood and plastic. Cross cutting miters, joints, etc. for picture frames, moldings, door casings, and fine joinery. Note: The blade provided is fine for most wood cutting operations, but for fine joinery cuts or cutting plastic, use one of the accessory blades available from your Ryobi dealer. BEVEL LOCK KNOB 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 RYOBI AUTHORIZED SERVICE CENTER. OPERATION WARNING: Before starting any cutting operation, clamp or bolt your miter saw to a workbench. Never operate your miter saw on the floor or in a crouched position. Failure to heed this warning can result in serious personal injury. CUTTING A SLOT IN THE ZERO CLEARANCE THROAT PLATE In order to use your compound miter saw, you must cut a slot through the zero clearance throat plate to allow for blade clearance. To cut the slot, set your saw at 0° miter, turn saw on and allow the blade to reach full speed, then carefully make a straight cut as far as it will go through the throat plate. Turn your saw off and allow the blade to come to a complete stop before raising the saw arm. Next, adjust the bevel angle to 45°, turn your saw on and allow the blade to reach full speed, then carefully make another cut through the zero clearance throat plate. The slot in the throat plate will then be wide enough to allow the blade to pass through it at any angle from 0° to 45°. WARNING: To avoid serious personal injury, keep your hands outside the no hands zone; at least 3 in. (7.6 cm) 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. Page 19 OPERATION CUTTING WITH MITER SAW YOUR COMPOUND Place the workpiece flat on the miter 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 a board is placed against the fence, the board could collapse on the blade at the end of the cut, jamming the blade. See Figures 36 and 37. When cutting long pieces of lumber or molding, support the opposite end of the stock with a roller stand or with a work surface level with the saw table. See Figure 34. 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. Use the optional work clamp or a C-clamp to secure the workpiece when possible. See Figure 29. WARNING: When using a work clamp or C-clamp to secure your workpiece, clamp 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 the blade will cause motor stalling and kickback. This situation could cause an accident resulting in possible serious personal injury. CROSSCUTTING See Figure 29. A crosscut is made by cutting across the grain of the workpiece. A straight crosscut is made with the miter table set at the 0° position. Miter crosscuts are made with the miter table set at some angle other than zero. TO CROSSCUT WITH YOUR MITER SAW Pull out the lock pin and lift saw arm to its full height. Loosen the miter lock handle. Rotate the miter lock handle approximately one-half turn to the left to loosen. Press the miter lock plate down with your thumb and hold. Rotate the control arm until the pointer aligns with the desired angle on the miter scale. Release the miter lock plate. Note: You can quickly locate 0°, 22-1/2° left or right, and 45° left or right by releasing the lock plate as you rotate the control arm. The lock plate will seat itself in one of the positive stop notches, located in the miter table frame. Tighten the miter lock handle securely.
