When not in use, before servicing, or when changing attachments, blades, bits, cutters, etc., all tools should be disconnected from power source. GUARD AGAINST ELECTRICAL SHOCK by preventing body contact with grounded surfaces. For example: pipes, radiators, ranges, refrigerator enclosures. 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 result in injury. KEEP GUARDS IN PLACE and in good working order. REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of checking to see that keys and adjusting wrenches are removed from tool before turning it on. NEVER STAND ON TOOL. Serious injury could occur if the tool is tipped. KEEP WORK AREA CLEAN. Cluttered areas and benches invite accidents. DO NOT leave tools or pieces of wood on the tool while it is in operation. 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 must be properly repaired or replaced by an authorized service center to avoid risk of personal injury. DO NOT USE IN DANGEROUS ENVIRONMENTS. Do not use power tools in damp or wet locations or expose 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. USE THE RIGHT DIRECTION OF FEED. Feed work into a blade, cutter, or sanding spindle against the direction or rotation of the blade, cutter, or sanding spindle only. MAKE WORKSHOP CHILDPROOF with padlocks, master switches, or by removing starter keys. DON’T FORCE THE TOOL. It will do the job better and safer at the feed rate for which it was designed. NEVER LEAVE TOOL RUNNING UNATTENDED. TURN THE POWER OFF. Don’t leave tool until it comes to a complete stop. USE THE RIGHT TOOL. Do not force the tool or attachment to do a job for which it was not designed. PROTECT YOUR LUNGS. Wear a face or dust mask if the cutting operation is dusty. 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 gauge 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 gauge. The smaller the gauge number, the heavier the cord. PROTECT YOUR HEARING. Wear hearing protection during extended periods of operation. DO NOT ABUSE CORD. Never carry tool by the cord or yank it to disconnect from receptacle. Keep cord from heat, oil, and sharp edges. USE OUTDOOR EXTENSION CORDS. When tool is used outdoors, use only extension cords with approved ground connection that are intended for use outdoors and so marked. DRESS PROPERLY. Do not wear loose clothing, neckties, or jewelry that can get caught and draw you into moving parts. Rubber gloves and nonskid footwear are recommended when working outdoors. Also wear protective hair covering to contain long hair. KEEP BLADES CLEAN, SHARP, and with sufficient set. Sharp blades minimize stalling and kickback. Blade coasts after being turned off. ALWAYS WEAR SAFETY GLASSES WITH SIDE SHIELDS. Everyday eyeglasses have only impactresistant lenses, they are not safety glasses. 3 GENERAL SAFETY RULES NEVER USE IN AN EXPLOSIVE ATMOSPHERE. Normal sparking of the motor could ignite fumes. DO NOT USE TOOL IF SWITCH DOES NOT TURN IT ON AND OFF. Have defective switches replaced by an authorized service center. Inspect TOOL CORDS periodically. If damaged, have repaired by a qualified service technician at an authorized service facility. The conductor with insulation having an outer surface that is green with or without yellow stripes is the equipment-grounding conductor. If repair or replacement of the electric cord or plug is necessary, do not connect the equipment-grounding conductor to a live terminal. Repair or replace a damaged or worn cord immediately. Stay constantly aware of cord location and keep it well away from the rotating blade. USE ONLY CORRECT BLADES. 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. 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. NEVER START A TOOL WHEN ANY ROTATiNG COMPONENT IS IN CONTACT WITH THE WORKPIECE. DO NOT operate A tool while under the influence of drugs, alcohol, or any medication. When servicing use only identical replacement parts. Use of any other parts may create a hazard or cause product damage. DOUBLE CHECK ALL SETUPS. Make sure blade is tight and not making contact with saw or workpiece before connecting to power supply. Inspect EXTENSION CORDS periodically and replace if damaged. 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. 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. 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. SPECIFIC SAFETY RULES FIRMLY CLAMP OR BOLT the tool to a workbench or table at approximately hip height. 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 the power off. Use this saw to cut wood, wood products and some plastics only. Do not cut metals, ceramics or masonry products. 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. 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. Always use a clamp to secure the workpiece when possible. 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. (bevel function) by securely tightening the bevel lock knob. NEVER cut more than one piece at a time. Do not stack more than one workpiece on the saw table at a time. MAKE SURE THE MITER TABLE AND SAW ARM (BEVEL FUNCTION) ARE LOCKED IN POSITION BEFORE OPERATING THE SAW. Lock the miter table by securely tightening the miter lock levers. Lock the saw arm 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. 4 SPECIFIC SAFETY RULES Never hand hold a workpiece that is too small to be clamped. Keep hands clear of the cutting area. 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 of a second is sufficient to inflict severe injury. NEVER reach behind, under, or within three inches of the blade and its cutting path with your hands and fingers for any reason. 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. 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. 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. NEVER stand or have any part of your body in line with the path of the saw blade. THIS TOOL should have the following markings: 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. 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. a) b) c) d) e) f) g) h) Wear eye protection. Keep hands out of path of saw blade. Do not operate saw without guards in place. Do not perform any operation freehand. Never reach around saw blade. Turn off tool and wait for saw blade to stop before raising saw arm, moving workpiece or changing settings. Disconnect the saw from the power source before changing blade or servicing.

All exposed metal parts are isolated from the internal metal motor components with protecting insulation. Double insulated tools do not need to be grounded. 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 product 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 listed by Underwriter’s Laboratories (UL) should be used. When working outdoors with a product, use an extension cord that is designed for outside use. This type of cord is designated with “WA” on the cord’s jacket. Before using any extension cord, inspect it for loose or exposed wires and cut or worn insulation. WARNING: The double insulated system is intended to protect the user from shock resulting from a break in the tool’s internal wiring. Observe all normal safety precautions to avoid electrical shock. NOTE: Servicing of a product 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 authorized service center for repair. Always use original factory replacement parts when servicing. **Ampere rating (on product data plate) 0-2.0 2.1-3.4 3.5-5.0 5.1-7.0 7.1-12.0 12.1-16.0 Cord Length Wire Size (A.W.G.) 25' 16 16 16 16 14 14 ELECTRICAL CONNECTION 50' 16 16 16 14 14 12 This tool has a precision-built electric motor.

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. Fig. 9 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. Base Work Clamp Fig. 10 14 ASSEMBLY To Install / replace the Blade See Figures 11 - 12. WARNING: A 12 in. blade is the maximum blade capacity of the saw. Never use a blade that is too thick to allow outer blade washer to engage with the flats on the spindle. Larger blades will come in contact with the blade guards, while thicker blades will prevent the blade bolt from securing the blade on the spindle. Either of these situations could result in a serious accident and can cause serious personal injury. Unplug the saw. Raise the saw arm. Rotate lower blade guard up and remove screw. Rotate blade bolt cover up and back to expose the blade bolt. Depress the spindle lock button and rotate the blade bolt until the spindle locks. Using the wrench provided, loosen and remove the blade bolt. Note: The blade bolt has left hand threads. Turn blade bolt clockwise to loosen. Remove outer blade washer. Do not remove inner blade washer. Wipe a drop of oil onto inner blade washer and outer blade washer where they contact the blade. Spindle Lock Button Fig. 11 NOTE: before use, replace SCREW and tighten SECURELY to prevent guard movement SCREW Lower blade guard WARNING: Blade BOLT cover If inner blade washer has been removed, replace it before placing blade on spindle. Failure to do so could cause an accident since blade will not tighten properly. Fit saw blade inside lower blade guard and onto spindle. The blade teeth point downward at the front of saw as shown in figure 12. Replace outer blade washer. Double “D” flats on blade washers align with flats on spindle. Depress spindle lock button and replace blade bolt. Note: The blade bolt has left hand threads. Turn blade bolt counterclockwise to tighten. Blade To LOOSEN Flat(S) on Spindle Caution: Always install the blade with the blade teeth and the arrow printed on the side of the blade pointing down at the front of the saw.

Remember that a careless fraction of a second is sufficient to inflict serious injury. 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. WARNING: Always wear eye protection with side shields marked to comply with ANSI Z87.1. Failure to do so could result in objects being thrown into your eyes, resulting in possible serious injury. WARNING: WARNING: EVER move the workpiece or make adjustment to any N cutting angle while the saw is running and the blade is rotating. Any slip can result in contact with the blade causing serious personal injury. Do not use any attachments or accessories not recommended by the manufacturer of this tool. The use of attachments or accessories not recommended can result in serious personal injury. To Cross cut APPLICATIONS See Figures 24 - 25. A cross cut is made by cutting across the grain of the workpiece. A straight cross cut is made with the miter table set at the 0° position. Miter cross cuts are made with the miter table set at some angle other than zero. 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. This product has been designed only for the purposes listed below: Cross cutting wood and plastic (do not cut metals, ceramics or masonry products.) Cross cutting miters, joints, etc. for picture frames moldings, door casings, and fine joinery Bevel cutting and compound cutting 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 the dealer. CROSS CUT WARNING: Before starting any cutting operation, clamp or bolt the compound miter saw to a workbench. Never operate the miter saw on the floor or in a crouched position. Failure to heed this warning can result in serious personal injury. WARNING: To avoid serious personal injury, always tighten the miter lock handle securely before making a cut. Failure to do so could result in movement of the control arm or miter table while making a cut. WARNING: To avoid serious personal injury, keep hands outside the no hands zone, at least 3 in. from the blade. Never perform any cutting operation freehand (without holding workpiece against the fence). The blade could grab the workpiece if it slips or twists. work clamp 19 Fig. 24 OPERATION Lift and hold the miter lock plate then rotate the miter table until the pointer aligns with zero on the miter scale. Release the miter lock plate. Note: You can quickly locate 0°, 15°, 22-1/2°, left or right, 31.62° and 45° left or right by releasing the miter lock plate as you rotate the control arm. The miter lock plate will seat itself in one of the positive stop notches, located in base. Tighten the miter lock handle securely. 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. 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 30. Align cutting line on workpiece with 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. Before turning on the saw, perform a dry run of the cutting operation just to make sure that no problems will occur when the cut is made. Grasp the saw handle firmly then squeeze the switch trigger. Allow several seconds for the blade to reach maximum speed. Slowly lower the blade into and through the workpiece. Release the switch trigger and allow the blade to stop rotating before raising the blade out of the workpiece. Wait until the electric brake stops blade from turning before removing the workpiece from the miter table. miter CUT WORK CLAMP Fig. 25 INDICATOR SCREW INDICATOR POINT scale indicator BEVEL SCALE TO Bevel Cut Fig. 26 See Figures 26 - 27.

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. 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 30. Align the 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 27. Before turning on the saw, perform a dry run of the cutting operation just to make sure that no problems will occur when the cut is made. Grasp the saw handle firmly then squeeze the switch trigger. Allow several seconds for the blade to reach maximum speed. Slowly lower the blade into and through the workpiece. Release the switch trigger and allow the saw blade to stop rotating before raising the blade out of the workpiece. Wait until the electric brake stops blade from turning before removing the workpiece from miter table. Compound Miter Cut Work CLAMP Fig. 28 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. 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. Lift and hold the miter lock plate then rotate the miter table until the pointer aligns with zero on the miter scale. Release the miter lock plate. to Compound Miter Cut See Figure 28. 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 cuts. 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. It may 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. Note: You can quickly locate 0°, 15°, 22-1/2°, left or right, 31.62° and 45° left or right by releasing the miter lock plate as you rotate the control arm. The miter lock plate will seat itself in one of the positive stop notches, located in the base. Tighten the miter lock handle securely. Loosen the bevel lock knob and move the saw arm to the left to the desired bevel angle. Bevel angles can be set from 0° to 45°. Once the saw arm has been set at the desired angle, securely tighten the bevel lock knob. Recheck miter angle setting. Make a test cut in scrap material. 21 OPERATION 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. 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 30. Align the 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. Before turning on the saw, perform a dry run of the cutting operation just to make sure that no problems will occur when the cut is made. Grasp the saw handle firmly then squeeze the switch trigger. Allow several seconds for the blade to reach maximum speed. Slowly lower the blade into and through the workpiece. Release the switch trigger and allow the saw blade to stop rotating before raising the blade out of the workpiece. Wait until the electric brake stops blade from turning before removing the workpiece from miter table. 45° x 45° COMPOUND MITER CUT Fig. 29 to SUPPORT LONG WORKPIECES See Figure 30. 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 worktable during the cutting operation. Use the optional work clamp or a C-clamp to secure the workpiece. Long workpiece 0 Workpiece supports 22 Fig. 30 OPERATION CUTTING COMPOUND MITERS To aid in making the correct settings, the compound angle setting chart below has been provided.

COMPOUND-ANGLE SETTINGS FOR POPULAR STRUCTURES 23 OPERATION cutting crown molding When setting the bevel and miter angles for compound miters, remember that the settings are interdependent; changing one angle changes the other angle as well. Keep in mind that the angles for crown molding 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 on the desired cut for the application. See the chart for correct angle settings and correct positioning of crown molding on miter table. The settings in the chart 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 the miter saw. This 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 miter table See Figure 31. 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. 52° ceiling 38° w a l l inside corner Fence Fence Top edge against fence = LEFT SIDE, INSIDE CORNER RIGHT SIDE, OUTSIDE CORNER outside corner BOTTOM edge against fence = RIGHT SIDE, INSIDE CORNER LEFT SIDE, OUTSIDE CORNER MITER Table MITER Table crown molding flat on miter table 24 Fig. 31 OPERATION Bevel Angle Setting Type of Cut 33.85° Left side, inside corner 1.

When cutting warped material, always make sure it is positioned on the miter table with the convex side against the fence as shown in figure 32. If the warped material is positioned the wrong way as shown in figure 33, it will pinch the blade near the completion of the cut. clamping wide workpieces See Figure 34. When cutting wide workpieces, such as 2 in. x 6 in., boards should be clamped with a C-clamp as shown in figure 34. WIDE BOARD Right Fig. 32 Fig. 34 25 ADJUSTMENTS POSITIVE STOP ADJUSTMENTS WARNING: See Figure 35. Note: These adjustments were made at the factory and normally do not require readjustment. To adjust: Unplug the saw. Using two wrenches (one on the lock nut and one for the positive stop adjustment screw), loosen the lock nut securing the positive stop adjustment screw. Loosen the bevel lock knob by turning the knob counterclockwise. Square the blade to the miter table as described in the Assembly section of this manual. Retighten bevel lock knob. Next, retighten lock nut securing the positive stop adjustment screw. Recheck blade-to-table alignment. Note: The above procedure can be used to check blade squareness of the saw blade to the miter table at both 0° and 45° angles. The saw has three scale indicators, two on the bevel scale and one on the miter scale. After squaring adjustments have been made, it may be necessary to loosen the indicator screws and reset them to zero. Before performing any adjustment, make sure the tool is unplugged from the power supply. Failure to heed this warning could result in serious personal injury. The compound miter saw has been adjusted at the factory for making very accurate cuts. However, some of the components might have been jarred out of alignment during shipping. Also, over a period of time, readjustment will probably become necessary due to wear. After unpacking the saw, check the following adjustments before you begin using the saw. Make any readjustments that are necessary and periodically check the parts alignment to make sure that the saw is cutting accurately. CAUTION: Do not start the compound miter saw without checking for interference between the blade and the throat plate. Damage could result to the blade if it strikes the throat plate during operation of the saw. PIVOT ADJUSTMENTS Note: These adjustments were made at the factory and normally do not require readjustment. BEVEL LOCK KNOB TRAVEL PIVOT ADJUSTMENT Positive Stop Adjustment Screw FOR 0° ANGLES 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 authorized service center. Positive Stop Adjustment Screw FOR 45° ANGLES Bevel Pivot Adjustment The 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 authorized service center. DEPTH STOP The depth stop limits the blade’s downward travel. It allows the blade to go below the miter table enough to maintain full cutting capacities. The depth stop positions the blade 1/4 in. from the miter table s upport. NOTE: The miter table support is located inside the miter table. The depth stop is factory set to provide maximum cutting capacity for the 12 in. blade provided with the saw. Therefore, the saw with blade provided should never need adjustments. Lock Nut(S) 26 Fig. 35 MAINTENANCE Brush Cap WARNING: When servicing, use only identical replacement parts. Use of any other parts may create a hazard or cause product damage.

Brush Cap Fig. 36 GENERAL MAINTENANCE 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, dust, oil, grease, etc. Brush REPLACEMENT See Figure 36. The saw has externally accessible brush assemblies that should be periodically checked for wear. Proceed as follows when replacement is required: Unplug the saw. WARNING: Do not at any time let brake fluids, gasoline, petroleumbased products, penetrating oils, etc., come in contact with plastic parts. Chemicals can damage, weaken or destroy plastic which may result in serious personal injury. WARNING: Failure to unplug the saw could result in accidental starting causing serious injury. Remove brush cap with a screwdriver. Brush assembly is spring loaded and will pop out when you remove brush cap. Remove brush assembly. Check for wear. Replace both brushes when either has less than 1/4 in. length of carbon remaining. Do not replace one side without replacing the other. Reassemble using new brush assemblies. Make sure curvature of brush matches curvature of motor and that brush moves freely in brush tube. Make sure brush cap is oriented correctly (straight) and replace. Tighten brush cap securely. Do not overtighten. Electric tools used on fiberglass material, wallboard, spackling compounds, or plaster are subject to accelerated wear and possible premature failure because the fiberglass chips and grindings are highly abrasive to bearings, brushes, commutators, etc. Consequently, we do not recommend using this tool for extended work on these types of materials. However, if you do work with any of these materials, it is extremely important to clean the tool using compressed air. 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. 27 OPERATOR’S MANUAL 10 in.

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. • SERVICE Now that you have purchased your tool, should a need ever exist for repair parts or service, simply contact your nearest Authorized Service Center.
