It's safer than using your hand and frees both hands to operate tool. tions. Failure to follow all instructions listed below, may result in electric shock, fire and/or serious personal injury. n DON'T OVERREACH. Keep proper footing and balance at all times. READ ALL INSTRUCTIONS n MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for better and safer performance.
GENERAL SAFETY RULES n 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.
SPECIFIC SAFETY RULES n NEVER hand hold a workpiece that is too small to be clamped. Keep hands clear of the cutting area. n 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. n NEVER reach behind, under, or within three inches of the blade and its cutting path with your hands and fingers for any reason.
SYMBOLS Some of the following symbols may be used on this tool. Please study them and learn their meaning. Proper interpretation of these symbols will allow you to operate the tool better and safer.
SYMBOLS The following signal words and meanings are intended to explain the levels of risk associated with this product. SYMBOL SIGNAL MEANING DANGER: Indicates an imminently hazardous situation, which, if not avoided, will result in death or serious injury. WARNING: Indicates a potentially hazardous situation, which, if not avoided, could result in death or serious injury.

ASSEMBLY UNPACKING WARNING: Do not attempt to modify this tool or create accessories not recommended for use with this tool. Any such alteration or modification is misuse and could result in a hazardous condition leading to possible serious personal injury. This product requires assembly. n Carefully lift saw from the carton by the carrying handle and the saw base, and place it on a level work surface. NOTE: This saw is heavy.
ASSEMBLY As mentioned previously, the saw has been factory assembled and adjusted. The miter lock handle, dust guide, and blade are the only parts that have to be installed. EXHAUST PORT MITER LOCK HANDLE See Figure 9. Cut the tie-wraps holding the saw arm and the miter lock in place. To install the miter lock handle, place the threaded stud into the threaded hole in the control arm. Turn clockwise to tighten. DUST GUIDE Fig. 10 DUST BAG See Figure 11. A dust bag is provided for use on this miter saw.
ASSEMBLY TABLE EXTENSIONS See Figures 12 - 13. If you plan to use the stop block, slide the stop block on the back arm of the desired table extension first. TABLE EXTENSION To install table extensions, insert the ends of extensions into the holes in the sides of the base. Adjust the extensions to the desired length. Secure them in place by positioning a clamp bracket under each table extension beneath the miter table. Orient each clamp bracket as shown in figure 13.
ASSEMBLY WORK CLAMP TO INSTALL BLADE See Figure 14. 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. See Figures 15 - 17. WARNING: A 10 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.
ASSEMBLY PHILLIPS SCREW WARNING: If inner blade washer has been LOWER BLADE GUARD removed, replace it before placing blade on spindle. Failure to do so could cause an accident since blade will not tighten properly. n Fit saw blade inside lower blade guard and onto spindle. The blade teeth point downward at the front of saw as shown in figure 15. BLADE BOLT COVER 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.
ASSEMBLY MOUNTING THE LASER GUIDE ALIGNING THE LASER GUIDE LINE See Figure 18. n Unplug the saw. See Figure 19. The laser guide will generate a red colored line on the work surface when the 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.
ASSEMBLY NOTE: Many of the illustrations in this manual show only portions of the compound miter saw. This is intentional so that we can clearly show points being made in the illustrations.

OPERATION CUTTING COMPOUND MITERS To aid in making the correct settings, the compound angle setting chart below has been provided. Since compound cuts are the most 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 OF SIDE 0° 5° 10° 15° 20° 25° 30° 35° 40° 45° 50° NUMBER OF SIDES 4 5 6 7 8 M- 45.00° B- 0.00° M- 44.89° B- 3.53° M- 44.56° B- 7.05° M- 44.01° B- 10.55° M- 36.00° B- 0.00° M- 30.
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. The 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. Keep in mind that the angles for crown moldings are very precise and difficult to set.

ADJUSTMENTS DEPTH STOP WARNING: Before performing any adjustment, make sure the tool is unplugged from the power supply and the switch is in the OFF ( O ) position. Failure to heed this warning could result in serious personal injury. See Figure 43. 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 support.
ADJUSTMENTS DEPTH STOP ADJUSTMENTS n Lower the blade into the miter table. Check blade clearance and maximum cutting distance (distance from fence where blade enters) to front of miter table slot. n Readjust if necessary. n Tighten the hex nut with a 10 mm wrench or adjustable wrench. n To prevent the depth stop adjustment screw from turning while tightening the hex nut, carefully hold it with the hex key wrench while tightening the hex nut. See Figure 43. n Unplug the saw.
MAINTENANCE CHANGING THE BATTERIES SCREWS See Figure 45. n Unplug the saw. LASER GUIDE SUPPORT Remove the laser guide from the saw. Lay laser guide on a flat surface with the two phillips screws facing upward. Remove the screws and separate the laser guide cover from the laser guide support. Remove the three button cell batteries using a non-conductive device such as a toothpick. NOTE: Replace the batteries with silver oxide batteries that have a rating of 1.
