READ ALL INSTRUCTIONS

KNOW YOUR POWER TOOL. Read the operator's manual carefully. Learn the saw's applications and limita- tions as well as the specific potential hazards related to this tool. GUARD AGAINST ELECTRICAL SHOCK by prevent- ing 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. Getin 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. AI visitors should wear safety glasses and be kept a safe distance from work area. Do not let visitors contact tool or exten- sion 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 cordis 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. À 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

ALWAYS WEAR SAFETY GLASSES WITH SIDE

SHIELDS. Everyday eyeglasses have only impact-resis- tant lenses; they are NOT safety glasses. WEAR A DUST MASK to keep from inhaling fine par- ticles. PROTECT YOUR HEARING. Wear hearing protection during extended periods of operation. SECURE WORK. Use clamps or a vise to hold work when practical. lt's safer than using your hand and frees both hands to operate tool. DO NOT OVERREACH. Keep proper footing and bal- ance at all times. MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for better and safer performance. Follow instruc- tions 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 operators manual for recommended accessories. The use of improper accessories may case risk of injury. NEVER STAND ON TOOL. Serious injury could occur if thetoolistipped orifthe 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. À 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 work- bench 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 incor- rect. The maximum blade capacity of your saw is 12 in. KEEP BLADES CLEAN, SHARP, AND WITH SUFFI- CIENT SET. Sharp blades minimize stalling and kick- back. 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.

= 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 cut- ting 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 PATHIS 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 startthe saw with the blade touchingthe 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 OP- ERATING 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 caitching 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. AI-

ways place the workpiece to be cut on the miter table and position it firmly against the fence as a backstop. Always use the fence. Page 5 NEVER reach behind, under, or within three inches ofthe 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 POSI-

TIONS 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 raisingit out ofthe 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. Al repairs, whether electrical or mechanical, should be made at your nearest autho- rized service center. WHEN SERVICING, use only identical Ryobi replace- ment parts. Use of any other parts may create a hazard or cause product damage. NEVER USE THIS TOOL IN AN EXPLOSIVE ATMO- SPHERE. 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. 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 re- placed before resuming operation. DO NOT OPERATE THIS TOOL WHILE UNDER THE INFLUENCE OF DRUGS, ALCOHOL, OR ANY MEDI- CATION. 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.

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 LIGHT- ING 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 con- nected 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. À WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemi- cals known to cause cancer, birth defects or other repro- ductive 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 tothese chemicals, workin a well ventilated area and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles.

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 mitertable base. This zone is identified by no hands zone labels placed inside the marked lines on the mitertable 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 tothe workpiece, that area which willbe, or has been, cut by the blade. Set The distance that the tip ofthe 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 cuis a slot through the throat plate the exact width of the blade. This provides for a zero clearance kerf that minimizes workpiece tear-out. Page 6

À WARNING: To prevent accidental starting that could cause possible serious personal injury, assemble all parts, make sure all adjustments are complete, and make sure all fasteners are secure before connecting saw to power supply. Saw should never be connected to power supply when you are assembling parts, making adjustments, installing or re- moving blades, or when not in use.

See Figure 7. To install the miter lock handle, place the threaded stud on the end of the miter lock handle into the threaded hole in the control arm under miter table. Turn clockwise to tighten. DUST GUIDE See Figure 8. To install the dust guide, place the end over the exhaust port in the upper blade guard. Turn the guide so that the open endis facing down. DUST BAG See Figure 9. A dust bag is provided for use on your miter saw. lt fits over the exhaust port on the upper blade guard. To install it, remove dust guide from exhaust port. Then, squeeze the two metal clips to open the mouth of the bag and slide it on the exhaust port. Release the clips. The metal ring in the bag should lock in between the grooves on the exhaust port. To remove the dust bag for emptying, simply reverse the above procedure. WORK CLAMP See Figure 10. 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 ofthe work clamp to secure the workpiece prior to making the cut. À WARNING: In some operations, the work clamp assembly may interfere with the operation ofthe 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. Follow these directions to install the work clamp: m 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. À 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.

BEVEL PIVOT ADJUSTMENT

M Your compound miter saw should bevel easily by loos- ening the bevel lock knob and tilting the saw arm to the left. M lf movement is tight or if there is play in the pivot, have saw repaired by at your nearest RYOBI AUTHORIZED SERVICE CENTER. À WARNING: Do noi 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. APPLICATIONS (Use only for the purposes listed below) m Cross cutting wood and plastic. M 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 cuis or cutting plastic, use one of the accessory blades available from your Ryobi dealer. OPERATION À 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. À 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. 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’. Page 19

MITER SAW À 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 preventthe 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 atthe 0’ position. Miter crosscuts are made with the miter table set at some angle other than zero.

A compound miter cut is a cut made using a miter angle and a bevel angle at the same time. This type of cut is used to make picture frames, cut molding, make boxes with sloping sides, and for certain roof framing cuis. To make this type of cut the control arm on the miter 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 miter setups due to the interaction of the two angle settings. Adjustments of miter and bevel settings are interdependent with one another. Each time you adjust the miter setting you change the effect of the bevel setting. Also, each time you adjust the bevel setting you change the effect of the miter setting. ltmay 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 material before making a finish cut in good material. TO MAKE A COMPOUND CUT WITH YOUR MITER SAW M Pull out the lock pin and lift saw arm to its full height. Æ Loosenthe miter lock handle. Rotate the miter lock handle approximately one-half turn to the left to loosen. m Press the miter lock plate down with your thumb and hold. m Rotaie the control arm until the pointer aligns with the desired angle on the miter scale. r à COMPOUND MITER CUT WORK CLAMP U Fig. 82 ] m Release the miter lock plate.

SUPPORT LONG WORKPIECES

See Figure 34. Long workpieces need extra supports. Supports should be placed along the workpiece so it does not sag. The support should let the workpiece lay flat on the base of the saw and work table during the cutting operation. Use the optional work clamp or a C-clamp to secure the workpiece.

To aid in making the correct settings, the compound angle setting chart below has been provided. Since compound cuts are the mosi difficult to accurately obtain, trial cuts should be made in scrap material, and much thought and planning made, prior to making your required cut.

PITCH NUMBER OF SIDES

Your compound miter saw does an excellent job of cutting crown molding. In general, compound miter saws do a better job of cutting crown molding than any other tool made. In order to fit properly, crown molding must be compound mitered 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 MITERTABLE

See Figure 35. 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 miter table and against the fence. When setting the bevel and miter angles for compound miters, rememberthatthe settings are interdependent; chang- ing 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 scrap molding. Also most walls do not have angles of exactly 90", therefore, you will need to fine tune your settings. When cutting crown molding by this method the bevel angle should be set at 33.85 The miter angle should be set at 31.62’ either right or left, depending onthe desired cut forthe application. See the chart below for correct angle settings and correct positioning of crown molding on miter table. The settings in the chart below can be used for cutting All Standard (U.S.) crown molding with 52’ and 38 angles. The crown molding is placed flat on the miter table using the compound features of your miter saw. € à 52 CEILING

Tighten screw securely. À DANGER: Laser radiation. Avoid directeye contact with light source. OPERATION See Figure 40. The laser guide will generate a red colored line on the work surface when the saw blade is spinning above 500 rpm. The red laser line will appear as a broken line on the workpiece when the blade assembly is in the uppermost position and the motor switch is activated. This broken line will let you see your mark and your laser guide line atthe same time, and will assist you in lining up your mark for more accurate cutting of the workpiece. ALIGNMENT Align the laser line and your mark with the blade at the uppermost position. Once both lines are in alignment, do not move the workpiece until after you have finished cutting. As the blade assembly is lowered toward the workpiece, the broken line will become solid. Make several practice cuts on different styles and thickness of material. Follow the directions below for using your Laser Guide. Removing Your Mark: (workpiece left of blade) Position the laser line near the left edge of your mark on the work surface in order to remove the mark. To Cut Your Mark: Position the laser line near or over your mark on the work surface in order to cut the mark. To Leave Your Mark: Position the laser line near the right edge of your mark on the work surface in order to leave the mark. After you have become familiar with using your Laser Guide, you will be able to remove, cut, or leave your mark on the work surface. Practice will teach you the correct position for aligning the laser line with your mark. [ D» HEX KEY BOLT SPINDLE INNER BLADE WASHER HEX KEY Fig. 39 BROKEN RED LINE Page 27
