Always operate saw in well-ventilated area and provide for proper dust removal. 3 COMPOUND MITER SAW SAFETY 18. MAKE SURE the blade is not contacting the workpiece before the switch is turned ON. SPECIFIC SAFETY INSTRUCTIONS FOR THIS COMPOUND MITER SAW 19. IMPORTANT: After completing the cut, release the power switch and wait for the blade to stop before returning the saw to the raised position. 1. USE ONLY CROSS-CUTTING SAW BLADES. When using carbide tipped blades, make sure they have a negative hook angle. IMPORTANT: DO NOT USE THIN KERF BLADESthey can deflect and contact guard and can cause possible injury to the operator. 20. MAKE SURE the blade has come to a complete stop before removing or securing the workpiece, changing the workpiece angle, or changing the angle of the blade. 2. DO NOT operate the miter saw until it is completely assembled and installed according to these instructions. 21. NEVER cut metals or masonry products with this tool. This miter saw is designed for use on wood and wood-like products. 3. IF YOU ARE NOT thoroughly familiar with the operation of miter saws, seek guidance from your supervisor, instructor, or other qualified person. 22. NEVER cut small pieces. If the workpiece being cut would cause your hand or fingers to be within 7-1/4” inches of the saw blade the workpiece is too small. 4. ALWAYS hold the work firmly against the fence and table. DO NOT perform any operation free hand (use clamp wherever possible). 23. PROVIDE adequate support to the sides of the saw table for long work pieces. 5. KEEP HANDS out of the path of the saw blade. If the workpiece you are cutting would cause your hands to be within 7-1/4” inches of the saw blade, the workpiece should be clamped in place before making the cut. 24. NEVER use the miter saw in an area with flammable liquids or gases. 25. NEVER use solvents to clean plastic parts. Solvents could possibly dissolve or otherwise damage the material. 6. BE SURE the blade is sharp, runs freely, and is free of vibration. 26. SHUT OFF the power before servicing or adjusting the tool. 7. ALLOW the motor to come up to full speed before starting a cut. 27. DISCONNECT the saw from the power source and clean the machine when finished using. 8. KEEP THE MOTOR AIR SLOTS CLEAN and free of chips or dust. 28. MAKE SURE the work area is clean before leaving the machine. 9. ALWAYS MAKE SURE all handles are tight before cutting, even if the table is positioned in one of the positive stops. 29. SHOULD any part of your miter saw be missing, damaged, or fail in any way, or any electrical component fail to perform properly, shut off the switch and remove the plug from the power supply outlet. Replace missing, damaged, or failed parts before resuming operation. 10. BE SURE both the blade and the collar are clean and the arbor bolt is tightened securely. 11. USE only blade collars specified for your saw. ELECTRICAL REQUIREMENTS 12. NEVER use blades larger or smaller in diameter than 10-inches. 13. NEVER apply lubricants to the blade when it is running. POWER SUPPLY AND MOTOR SPECIFICATIONS The AC motor used in this saw is a universal, nonreversible type. See “MOTOR” in the “PRODUCT SPECIFICATIONS” section on page 2. To avoid electrical hazards, fire hazards, or damage to the tool, use proper circuit protection. Your saw is wired at the factory for 120V operation. Connect to a 120V, 15 Amp circuit and use a 15 amp. time delay fuse or circuit breaker. To avoid shock or fire, if power cord is worn or cut, or damaged in any way, have it replaced immediately. 14. ALWAYS check the blade for cracks or damage before operation. Replace a cracked or damaged blade immediately. 15. NEVER use blades recommended for operation at less than 4800 RPM. 16. ALWAYS keep the blade guards in place and use at all times. 17. NEVER reach around the saw blade. 4 ELECTRICAL REQUIREMENTS AND SAFETY 4. FUSES may “blow” or circuit breakers may trip frequently if: a. MOTOR is overloaded – overloading can occur if you feed too rapidly or make too many start/stops in a short time. b. LINE VOLTAGE is more than 10% above or below the nameplate voltage rating. For heavy loads, the voltage at motor terminals must equal the voltage specified on the nameplate. c. IMPROPER or dull saw blades are used. 5. Most motor troubles may be traced to loose or incorrect connections, overload, low voltage or inadequate power supply wiring. Always check the connections, the load and supply circuit if the motor doesn’t run well. Check minimum gauge for the length of cord you are using on the chart below. ELECTRICAL REQUIREMENTS – cont’d DOUBLE INSULATED The power tool is double insulated to provide a double thickness of insulation between you and tool’s electrical system. All exposed metal parts are isolated from the internal metal motor components with protecting insulation. Replacement parts – When servicing use only identical replacement parts. Polarized plugs – This saw has a plug that looks like the one shown below: GUIDELINES FOR EXTENSION CORDS Use a proper extension cord. 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. An undersized cord will cause a drop in line voltage, resulting in loss of power and cause overheating. The table below shows the correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord. To reduce the risk of electrical shock, this saw 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. Be sure your extension cord is properly wired and in good condition. Always replace a damaged extension cord or have it repaired by a qualified person before using it. Protect your extension cords from sharp objects, excessive heat and damp or wet areas. Double insulation does not take the place of normal safety precautions when operating this tool. To avoid electrocution: 1. Use only identical replacement parts when servicing a tool with double insulation. Servicing should be performed by a qualified technician. 2. Do not use power tools in wet or damp locations or expose them to rain or snow. Use a separate electrical circuit for your tools. This circuit must not be less than # 12 wire and should be protected with a 15 Amp time delay fuse. Before connecting the tool to the power line, make sure the switch is in the OFF position and the electric current is rated the same as the current stamped on the motor nameplate, running at a lower voltage will damage the motor. MOTOR SAFETY PROTECTION IMPORTANT: To avoid motor damage, the motor should be blown out or vacuumed frequently to keep sawdust from interfering with the motor ventilation. 1. CONNECT this saw to a 120V, 15 amp. circuit with a 15 amp. time delay fuse or circuit breaker. Using the wrong size fuse can damage the motor. 2. If the motor won’t start, release the trigger switch immediately. UNPLUG THE SAW. Check the saw blade to make sure it turns freely. If the blade is free, try to start the saw again. If the motor still does not start, refer to the “TROUBLESHOOTING GUIDE” 3. If the tool suddenly stalls while cutting wood, release the trigger switch, unplug the tool, and free the blade from the wood. The saw may now be started and the cut finished. MINIMUM GAUGE FOR EXTENSION CORDS (AWG) (When using 120 volts only) Ampere Rating Total length of cord in feet more than not more than 25’ 50’ 100’ 150’ 18 16 16 14 16 14 12 16 12 14 12 not recommended 0 6 6 10 18 10 12 12 16 16 14 CAUTION: In all cases make certain the receptacle in question is properly grounded.

(ASSEMBLY AND ADJUSTMENTS) Learn the use and function of the ON/OFF switch, lock-off switch, upper and lower blade guards, stop latch, bevel lock handle, and cover plate screws. Review and understand all safety instructions and operating procedures in this Operator’s Manual. (SAFETY & OPERATIONS) Review the MAINTENANCE and TROUBLESHOOTING GUIDE for your miter saw. To avoid injury or possible death from electrical shock: Make sure your fingers do not touch the plug’s metal prongs when plugging or unplugging your miter saw. (ELECTRICAL REQUIREMENTS AND SAFETY) Maintain tools with care. Keep the miter saw clean for best and safest performance. Follow instructions for lubricating. Don’t put lubricants on the blade while it’s spinning. Remove all adjusting wrenches from the tool before turning it on. USE ONLY RECOMMENDED ACCESSORIES Consult the ACCESSORIES and ATTACHMENTS section of this Operators Manual for recommended accessories. Follow the instructions that come with the accessory. The use of improper accessories may cause risk of injury to persons. Choose the correct 10 inch diameter blade for the material and the type of cutting you plan to do. Do not use Thin Kerf blades. Make sure the blade is sharp, undamaged and properly aligned. With the saw unplugged, push the cutting arm all the way down. Manually spin the blade and check for clearance. Tilt the miter head to a 45° bevel and repeat the test. BEFORE EACH USE Inspect your saw. Disconnect the miter saw. To avoid injury from accidental starting, unplug the saw before any adjustments, including set-up and blade changes. Compare the direction of rotation arrow on the guard to the direction arrow on the blade. The blade teeth should always point downward at the front of the saw. Tighten the arbor bolt. Tighten the cover plate screw. Check for damaged parts. Check for: Alignment of moving parts Damaged electric cords Binding of moving parts Mounting holes Function of arm return spring and lower guard: Push the cutting arm all the way down, then let it rise until it stops. The lower guard should fully close. Follow instructions in TROUBLESHOOTING GUIDE for adjustment if necessary. Other conditions that may affect the way the miter saw works. Make sure the blade and arbor collars are clean. Make sure all clamps and locks are tight and there is no excessive play in any parts. KEEP YOUR WORK AREA CLEAN Cluttered areas and benches invite accidents. To avoid burns or other fire damage, never use the miter saw near flammable liquids, vapors, or gases. Plan ahead to protect your eyes, hands, face and ears. Know your miter saw. Read and understand the Operator’s Manual and labels affixed to the tool. Learn its application and limitations as well as the specific potential hazards specific to this tool. To avoid injury from accidental contact with moving parts, don’t do layout, assembly, or setup work on the miter saw. Avoid accidental starting Make sure the switch is OFF before plugging the miter saw into a power outlet. 15 PLAN YOUR WORK workpiece, fence and table that will let the workpiece shift after it is cut. Keep the cut off piece free to move sideways after it is cut off. Otherwise, it could get wedged against the blade and thrown violently. Only the workpiece should be on the saw’s table. Secure work. Use clamps or a vise to help hold the work when it’s practical. Use the right tool. Don’t force a tool or attachment to do a job it was not designed to do. Use a different tool for any workpiece that can’t be held in a solidly braced, fixed position. CAUTION: This machine is NOT designed for cutting masonry, masonry products & ferrous metals (steel, iron, and iron-based metals.) Use this miter saw to cut only wood and wood by-products. Other material may shatter, bind the blade, or create other dangers. Remove all nails that may be in the workpiece to prevent sparking that could cause a fire. USE EXTRA CAUTION WITH LARGE OR ODD SHAPED WORKPIECES. Use extra supports (tables, sawhorses, blocks, etc.) for workpieces large enough to tip. Never use another person as a substitute for a table extension, or as an additional support for a workpiece that is longer or wider than the basic miter saw table, or to help feed, support, or pull the workpiece. Do not use this saw to cut small pieces. If the workpiece being cut would cause your hand or fingers to be within 7-1/4” inches of the saw blade workpiece is too small. Keep hands and fingers out of the “no hands zone” area marked on the saws table. When cutting odd shaped workpieces, plan your work so it will not bind in the blade and cause possible injury. Molding, for example, must lie flat or be held by a fixture or jig that will not let it move when cut. Properly support round material such as dowel rods, or tubing, which have a tendency to roll when cut, causing the blade to “bite”. DRESS FOR SAFETY Any power tool can throw foreign objects into the eyes. This can result in permanent eye damage. Everyday eyeglasses have only impact resistant lenses and are not safety glasses. Glasses or goggles not in compliance with ANSI Z87.1 could seriously injure you when they break. Do not wear loose clothing, gloves, neckties or jewelry (rings, watches). They can get caught and draw you into moving parts. Wear non-slip footwear. Tie back long hair. Roll long sleeves above the elbow. Noise levels vary widely. To avoid possible hearing damage, wear ear plugs when using any miter saw. For dusty operations, wear a dust mask along with safety goggles. INSPECT YOUR WORKPIECE Make sure there are no nails or foreign objects in the part of the workpiece being cut. Plan your work to avoid small pieces that may bind, or that are too small to clamp and get a solid grasp on. Plan the way you will grasp the workpiece from start to finish. Avoid awkward operations and hand positions. A sudden slip could cause your fingers or hand to move into the blade. To avoid injury, follow all applicable safety instructions, when cutting non-ferrous metals: Use only saw blades specifically recommended for non-ferrous metal cutting. Do not cut metal workpieces that must be hand held. Clamp workpieces securely. Cut non-ferrous metals only if you are under the supervision of an experienced person. WHEN SAW IS RUNNING DON’T OVER-REACH Keep good footing and balance. Keep your face and body to one side, out of the line of a possible kickback. NEVER stand in the line of the blade. Never cut freehand: Brace your workpiece firmly against the fence and table stop so it will not rock or twist during the cut. Make sure there is no debris between the workpiece and the table or fence. Make sure there are no gaps between the Don’t allow familiarity from frequent use of your miter saw to result in a careless mistake. A careless fraction of a second is enough to cause a severe injury. Before cutting, if the saw makes an unfamiliar noise or vibrates, stop immediately. Turn the saw OFF. Unplug the saw. Do not restart until finding and correcting the problem. 16 BODY AND HAND POSITION (FIG. P) Proper positioning of your body and hands when operating the miter saw will make cutting easier and safer. Never place hands near the cutting area. Position hands at least 7-1/4” away from the path of the blade. Hold workpiece firmly against the fence to prevent movement toward the blade. Keep hands in position until the trigger has been released and the blade has completely stopped. Before making a cut, with the power switch in the OFF position bring the saw blade down to the workpiece to see the cutting path of the blade. Keep children away. Keep all visitors a safe distance from the miter saw. Make sure bystanders are clear of the miter saw and workpiece. Don’t force tool. It will do the job better and safer at its designed rate. Feed the saw into the workpiece slowly with a firm downward motion. Before freeing jammed material: Turn switch OFF. Unplug the miter saw. Wait for all moving parts to stop. After finishing a cut, keep holding the upper blade assembly in the down position. Release the switch, and wait for all moving parts to stop before moving your hands. If the blade doesn’t stop within 6 seconds, unplug the saw and follow the instructions in TROUBLESHOOTING GUIDE section for adjusting the blade brake before using the saw again. TURNING THE SAW ON (Fig. Q) To reduce the likelihood of accidental starting, a thumb activated lock-OFF switch is located on top of the switch handle. The safety lock-OFF button (1) must be pushed forward before the trigger switch (2) can be activated and the miter saw started. Make the switch child-proof. Insert a padlock through the hole (3) in the trigger switch and lock it. This will prevent children and other unauthorized users from turning the switch ON. Fig. Q THE LASER -TRAC® Your tool is equipped with our latest innovation, the Laser -Trac®, a battery powered device using Class IIIa laser beams. The laser beams will enable you to preview the miter blade path on the workpiece to be cut before you begin your operation. Laser is activated when blade is rotating. Do not stare into beam or view directly with optical instruments. Do not remove the warning label affixed to the blade guard. Avoid direct eye contact with light source. Fig. P NOTE - The red laser line will appear as a dotted line when the motor is activated and the blade assembly is in the uppermost position. This broken line will assist you in aligning the mark on your workpiece with the cutting path of the saw blade. As you lower the blade assembly, the retractable guard will lift and turn the broken line into a solid red laser line. Laser Warning label: Max output <5mW DIODE LASER: 630-670nm, Complies with 21CFR 1040.10 and 1040. 11. OPERATION OF LASER 7-1/4” 7-1/4” With the blade assembly in the uppermost position: 1. Position your workpiece onto the miter saw. 2. Turn on the miter saw to activate the laser beam. 3. Verify the laser beam is aligned with the mark on the workpiece (WARNING - Do not lower the blade assembly during the alignment process). 4. If the mark on the workpiece is not aligned with the dotted laser line, turn off machine, wait for the blade to stop and reposition workpiece. 5. Turn on the miter saw and verify alignment. 6. Once alignment is achieved, secure workpiece with a clamping device and perform the cut. 17 MITER CUT (FIG. R) When a miter cut is required, unlock the miter table by turning the miter handle (1) counterclockwise. While holding the miter handle, press down on the positive stop locking lever (2). Rotate the miter table to the right or left with the miter handle. When the table is in the desired position as shown on the miter scale (3), release the positive stop locking lever and tighten the miter handle. The table is now locked at the desired angle. Positive stops are provided at 0°,15°,22.5°,31.6° and 45°. IMPORTANT: Always tighten the miter table lock handle before performing a cut. COMPOUND CUT (FIG. T) A compound cut is the combination of a miter and a bevel cut simultaneously. 1. Loosen the bevel lock handle (1) and position the cutting head at the desired bevel position. Lock the bevel lock handle. 2. Loosen the miter table lock handle (2). Press down the positive stop locking lever (3) and position the table at the desired angle. Release the positive stop locking lever and lock the miter handle. Fig. T Fig. R BEVEL CUT (FIG. S) When a bevel cut is required, loosen the bevel lock handle (1). Tilt the cutting head to the desired angle as shown on the bevel scale (2). The blade can be positioned at any angle, from a 90° straight cut (0° on the scale) to a 45° left bevel. Tighten the lock handle (1) to lock the desired cutting head in position. Positive stops are provided at 0 and 45°. CUTTING BOWED MATERIAL (FIG. U) A bowed workpiece must be positioned against the fence and secured with a clamping devise before cutting. Do not position workpiece incorrectly or try to cut the workpiece without the support of the fence. This will cause the blade to bind and could result in personal injury. Fig. U Fig. S 18 AUXILARY WOOD FENCE (FIG. W) When making multiple or repetitive cuts that result in cut-off pieces of one inch or less, it is possible for the saw blade to catch the cut-off piece and throw it out of the saw or into the blade guard and housing, possibly causing damage or injury. To minimize this an auxiliary wood fence can be mounted to your saw. Holes are provided in the saw fence to attach an auxiliary wood fence. This fence is constructed of straight auxiliary wood approximately 3/4 inch thick by 2-1/2 inches high by 18 inches long. Attach the wood fence securely and make a full depth cut to make a blade slot. Check for interference between the wood fence and the lower blade guard. Adjust if necessary. NOTE: This auxiliary fence is used only with the saw blade in the 0° bevel position (90° to the table). The auxiliary wood fence must be removed when bevel cutting. WORKPIECE SUPPORT (FIG. V) Long pieces need extra support. The support should be placed under the workpiece. Keep your hands out of the “no-hands” zone, positioned 7-1/4” or more away from the blade. The support must let the workpiece lay flat on the worktable during the cutting operation. NOTE: When mounted on a flat surface, the miter saw table is 3-1/8 inches high.

See “AUXILIARY WOOD FENCE” above. Fig. X CUTTING BASE MOLDING (FIG. Z) Base moldings and many other moldings can be cut on a compound miter saw. The setup of the saw depends on molding characteristics and applications, as shown. Perform practice cuts on scrap material to achieve best results: 1. Always make sure moldings rest firmly against fence and table. Use hold-down or C-clamps, whenever possible, and place tape on the area being clamped to avoid marks. 2. Reduce splintering by taping the cut area prior to making cut. Mark cut line directly on the tape. 3. Splintering typically happens due to wrong blade application and thinness of the material. Fig. Z VERTICAL MITER CUTTING (FIG. Y) To make a miter cut in a 2x4 workpiece (1-5/8” x 3-1/2”) in the vertical position on edge a spacer such as the auxiliary wood fence described in the “ AUXILIARY WOOD FENCE” section is required. Fig. Y NOTE: Always perform a dry run cut so you can determine if the operation being attempted is possible before power is applied to the saw. 20 CUTTING CROWN MOLDING (FIG. AA, BB) Your compound miter saw is suited for the difficult task of cutting crown molding. To fit properly, crown molding must be compound-mitered with extreme accuracy. The two surfaces on a piece of crown molding that fit flat against the ceiling and wall are at angles that, when added together equal exactly 90°. Fig. BB 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°. In order to accurately cut crown molding for a 90° inside or outside corner, lay the molding with its broad back surface flat on the saw table. When setting the bevel and miter angles for compound miters, remember that the settings are interdependent; changing one changes the other, as well. Also keep in mind that the angles from crown molding are very easy for these angles to shift slightly, all settings should be tested on scrap molding.

CHANGING THE LASER BATTERIES CHANGING THE BATTERIES (Fig. CC) Unplug your saw. 1 FIG. CC Failure to unplug your saw could result in accidental starting causing possible serious personal injury. 1. Remove the laser guide from the saw. 2. Loosen and remove the two screws (1), then remove the laser guide cover. 3. Remove the three batteries by sliding them out from their mounting braces using a non-conductive devise such as a toothpick. 4. Replace the batteries that have a rating of 1.5 volts (Number LR44). 5. Replace the laser guide cover, two screws and laser assembly onto the miter saw. Note: When replacing the batteries, the battery cover should be thoroughly cleaned. Use a soft paintbrush or similar device, to remove all sawdust and debris. 21 MAINTENANCE MAINTENANCE DANGER Never put lubricants on the blade while it is spinning. To avoid fire or toxic reaction, never use gasoline, naphtha acetone, lacquer thinner or similar highly volatile solvents to clean the miter saw. To avoid injury from unexpected starting or electrical shock, unplug the power cord before working on the saw. For your safety, this saw is double-insulated. To avoid electrical shock, fire or injury, use only parts identical to those identified in the parts list. Reassemble exactly as the original assembly to avoid electrical shock. REPLACING CARBON BRUSHES (FIG. DD) The carbon brushes furnished will last approximately 50 hours of running time, or 10,000 ON/OFF cycles. Replace both carbon brushes when either has less than 1/4” length of carbon remaining, or if the spring or wire is damaged or burned. To inspect or replace brushes, first unplug the saw. Then remove the black plastic cap (1) on the side of the motor (2). Remove the cap cautiously, because it is springloaded. Then pull out the brush and replace. Replace for the other side. To reassemble reverse the procedure. The ears on the metal end of the assembly go in the same hole the carbon part fits into. Tighten the cap snugly, but do not overtighten. NOTE: To reinstall the same brushes, first make sure the brushes go back in the way they came out. This will avoid a break-in period that reduces motor performance and increase wear. Fig. DD LOWER BLADE GUARD Do not use the saw without the lower blade guard. The lower blade guard is attached to the saw for your protection. Should the lower guard become damaged, do not use the saw until the damaged guard has been replaced. Develop a regular check to make sure the lower guard is working properly. Clean the lower guard of any dust or buildup with a damp cloth. AUTION: Do not use solvents on the guard. They could make the plastic “cloudy” and brittle. When cleaning the lower guard, unplug the saw from the power source receptacle to avoid unexpected startup. SAWDUST Periodically, sawdust will accumulate under the work table and base. This could cause difficulty in the movement of the worktable when setting up a miter cut. Frequently blow out or vacuum up the sawdust. If blowing sawdust, wear proper eye protection to keep debris from blowing into eyes. LUBRICATION All the motor 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. Lubrication the Following as Required: Chop pivot: light machine oil or aerosol will penetrate from the ends of the junction points. A qualified service technician can remove the pivot upstop to relieve tension, and the 2 metric set screws holding the shaft, in order to drive the shaft about 3/4” right. Exposed surfaces are lubricated with automotive type oil. Central pivot of plastic guard: Use light household oil (sewing machine oil ) on metal-to–metal or metal-to-plastic guard contact areas as required for smooth, quiet operation. Avoid excessive oil, to which sawdust will cling. Link: (which actuates the lower guard movement) may be oiled at the rear pivot, greased at ball bearing contact, and oiled where the link actuates the acetyl roller of the lower guard, if the down chop motion is hard to start. 22 TROUBLESHOOTING GUIDE To avoid injury from accidental starting, always turn switch OFF and unplug the tool before moving, replacing the blade or making adjustments.
