8 SAFETY INSTRUCTIONS SAFETY PRECAUTIONS FOR LASERS This miter saw has a built-in laser light. The is a Class II laser that emits a maximum output power of 1 mw, 635 nm wavelengths. These lasers do not normally present an optical hazard. However, DO NOT stare into the beam. Doing so can cause flash blindness. CAUTION: The label above is affixed to your tool. It indicates the location from which the saw emits the laser light. BE AWARE of the laser light location when using the tool. ALWAYS MAKE SURE that any bystanders in the vicinity of use are made aware of the dangers of looking directly into the laser. WARNING: LASER LIGHT. LASER RADIATION. Avoid Direct Eye Exposure. DO NOT stare into beam. Only turn laser beam on when making cuts. WARNING: Use of controls, adjustments or performance of procedures other than those specified in this manual may result in hazardous radiation exposure. WARNING: The use of optical instruments to view the laser beam, including but not limited to telescopes or transits, will increase eye hazard. 1. The laser should be used and maintained in accordance with the manufacture s instruction. 2. Never aim the beam at any person or any object other than the work piece. 3. Always ensure that the laser beam is aimed at a sturdy work piece without a reflective surface. Such surfaces as wood or other rough-coated surfaces are acceptable. Bright, shiny or reflective sheets and the like are not suitable for laser use, because the reflective surface could reflect the beam back at the operator. 4. Do not attempt to activate the laser when the tool housing is removed. 5. The laser is activated with a button switch that is independent of the main switch for the saw. 6. Do not replace the laser light assembly with a different type. Any repairs must be carried out by the laser manufacture or an authorized service agent. 7.

Compound cuts for decorative wood molding, such as chair rail, cove molding and picture frames and other fine joinery. This tool is NOT recommended for cutting ferrous metals, such as iron, steel, stainless steel, or alloys of these metals. Cut non-ferrous metals ONLY if you are under the supervision of an experienced person. DO NOT cut stone, brick, or concrete with this miter saw. Page 19

21 OPERATION WORKPIECE SUPPORT WARNING: Never use the help of another person as a substitute for a table extension or as a support for a work piece that is longer or wider than the basic miter table and the attached extension supports. Never have another person help feed, support, or pull the work piece instead of using table extensions. Hold-down clamp (Fig. 20) FIG. 20 Hold Down Clamp To use the fence (Fig. 19) FIG. 19 Upper Sliding Fence Extension Wing Lower Fence This clamp easily secures a work piece in either of two clamp holes behind the fence. 1. Rotate the knob to tighten the work piece. 2. With the saw turned off, move the head as assembly as if making a cut to check clearance with the clamps. 3. The clamp can secure the work piece horizontally. Align the work piece flush against the fence. This will help to eliminate the tendency of the teeth of the blade to bind. The fence can be used to support miter, bevel, and compound cuts. Upper and lower fences adjust for added precision. 1. Loosen the locking knob on the upper sliding fences to adjust them. The lower fences can be moved to either of two positions. 2. When making a crosscut or a miter cut, move the lower fence closer to the blade to better support the work piece. 3. When making a bevel cut, move the lower fence away from the blade to make sure the blade can t contact the fence. Pull or push the saw head fully back or forward when it is in the lowest position. Long work piece support Long work piece need extra support, the support should be placed along the work piece so the work piece does not sag. The support should let the work piece flat on the base and work table during the cutting operation. Use optional work clamp or C-clamp to secure the work piece. Clamping a wide work piece When cutting wide work pieces (such as 2 x 8 (5 x 20 cm) boards) the boards MUST BE clamped using the hold-down clamp provided or a C-clamp (sold separately). Page 20

22 OPERATION WARNING: When using the clamp included or a C-clamp (sold separately) to secure the work piece; clamp the work piece on one side of the blade ONLY. The work piece MUST remain unclamped on the other side of the blade to prevent the blade from binding in the work piece. The work piece binding the blade will cause the motor to stall and cause kickback, resulting in possible serious injury. HOW TO USE THE DUAL LASER LINE (FIG. 22) FIG. 22 WORKLIGHT ON/OFF (FIG. 21) FIG. 21 Worklight Turn on the work light LED switch for lighting in darker areas. WARNING: BEFORE starting any cutting operation, clamp or bolt your compound miter saw to a workbench or flat stable work surface. NEVER operate your miter saw on the floor or in a crouched position. Failure to heed this warning could result in serious personal injury. 1. Mark your work piece with a pencil line at the point to be cut. 2. Push the Laser ON/OFF switch to ON to activate the dual laser line. Align your pencil line in the middle of the dual laser lines. 4. Clamp your work piece in place using the hold-down clamp. 5. Follow all of the cutting instructions for the type of cut to be performed. ON/OFF SWITCH For safety, the ON/OFF switch is designed to prevent accidental starts.

26 OPERATION 14. Release the safety lock and the trigger switch, and turn the laser switch off. Allow the saw blade to stop rotating before raising the blade out of the work piece. CAUTION: Always perform a dry-run cut to determine whether the operation being attempted is possible before power is applied to the Miter Saw. COMPOUND MITER CUTTING (FIG. 29) FIG. 29 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 for decorative moldings, picture frames, and other fine joinery. To make this type of cut, the miter table must be rotated to the correct miter angle and the saw arm must be tilted to the correct bevel angle. Always take special care when making compound miter cuts, due to the interaction of the two angle settings. Adjustments of miter and bevel settings are interdependent. Whenever the miter setting is adjusted, the effect of the bevel setting also changes. Whenever the bevel setting is adjusted, the effect of the miter setting is changed. It may take several settings to obtain the desired cut. The first angle setting should be checked after setting the second angle, because 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. Compound Miter Cut with the Miter Saw: 1. Unplug the saw. WARNING: Failure to unplug the saw could result in accidental startup, which may cause serious injury. 2. Mark the cutting line on the work piece with a pencil. 3. Pull out the locking pin to release the saw arm. 4. Loosen the miter locking knob, and lift the miter-detent locking lever; rotate the miter table to desired miter angle. 5. Quickly locate 0, 15, 22.5, 31.6 and 45 left or right by the stops or clicks at these angle settings. 6. When the desired miter table setting is achieved, tighten the miter locking knob. WARNING: To avoid serious personal injury, always tighten the miter locking knob securely before making a cut. Failure to do so could result in movement of the control arm or miter table while making a cut. 7. To set the bevel angle, loosen the bevel locking lever by rotating it and tilt the saw arm to the desired bevel angle, as shown on the bevel scale. Bevel angles can be set from 0 to 48º left. 8. When the saw arm has been set at the desired angle, tighten the bevel locking lever securely. 9. Plug the saw into an electrical socket. Page 25

27 OPERATION 10. Place the work piece 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 the board is against the fence, the board could collapse on the blade at the end of the cut and jam the blade. 11. Turn on the dual lasers and align the pencil line in the middle of the dual laser lines. 12. Use the hold-down clamp to secure the work piece against the saw table and fence. 13. When cutting a long work piece, use extension wing to support the long work piece. 18. Release the safety lock and the trigger switch, and turn the laser switch off. Allow the saw blade to stop rotating before raising the blade out of the work piece. CHOP CUTS (FIG. 30) Chop cuts are used mainly for narrow pieces.

CUTTING WARPED MATERIAL (FIG ) FIG. 34 Top View WARNING: To avoid kickback and serious personal injury, never position the concave side of bowed or warped material against the fence. When cutting warped material, be certain that the material to be cut is positioned on the miter table with the convex side against the fence, as shown (Fig. 34). If the warped material is positioned the wrong way (Fig. 35), it will pinch the blade near the end of the cut. CUTTING BASE MOLDING (FIG. 36) FIG. 36 Fence Mitre at 0, Bevel at 45 Molding lying flat on miter table(before clamping) Miter Saw Fence Molding standing up against fence (before clamping) Right Mitre at 45, Bevel at 0 Miter Saw FIG. 35 Wrong Top View Base moldings and many other moldings can be cut on a miter saw. The setup of the saw depends on the base molding characteristics and applications, as shown. Perform practice cuts on scrap materials to achieve best result. 1. Always make sure that the molding rests firmly against the fence and table (Fig. 36). Use the hold-down clamp provided or use C-clamps (available separately), and place tape on the area being clamped to avoid marks on the work piece. 2. Reduce splintering by taping the cut area prior to making the cut. Mark the cutting line directly on the tape. Page 28

30 OPERATION 3. Splintering typically happens due to incorrect blade style, dull blade, thinness of work piece, or improperly dried wood. NOTICE: Always perform a dry-run cut so you can determine if the operation being attempted is possible before power is applied to miter saw. 4. Place the work piece 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 the board is against the fence, the board could collapse on the blade at the end of the cut and jam the blade (Fig. 34 and 35). 5. Align your pencil line in the middle of the dual laser lines. 6. When cutting long work pieces, use extension wing for extra support for the long work pieces. 7. Carefully follow all instructions for applicable miter, bevel or compound cuts. FIG. 37 CUTTING CROWN MOLDING (FIG. 37) WARNING: Always uses the hold-down clamp, and place tape on the area being clamped to avoid marks on the work piece. Your miter saw is ideal for cutting crown molding. To fit properly, crown molding must be compound-mitered with extreme accuracy. To fit flat against the ceiling and wall, the sum of the angles of the crown molding s two connecting surfaces must equal 90. When setting the bevel and miter angles for compound miter cuts, remember that the settings are interdependent; changing one also changes the other. Keep in mind that, because it is very easy for the angles of crown molding to shift slightly, all settings should be tested on scrap molding. Also, most walls do not have angles of precisely 90 ; therefore, you will need to fine-tune your settings. When cutting crown molding, the bevel angle should be set at 33.9, and the miter angle should be set at 31.6 either left or right, depending upon the desired cut for the application. See the following table for correct angle settings and correct positioning of the crown molding on the miter table. Page 29

31 Crown molding has a high top rear spring angle (the section that fits flat against the ceiling) of 52 and a bottom rear spring angle (the section that fits flat against the wall) of 38.
