LOOSE PARTS LIST The following items are included with your compound miter saw: Miter Saw Dust Bag Work Clamp Blade Wrench AAA Batteries (2) Rear Bracket/Carrying Handle Blade Operator’s Manual MITER SAW WORK CLAMP AAA BATTERIES DUST BAG BLADE BLADE WRENCH REAR BRACKET/ CARRYING HANDLE WARNING: The use of attachments or accessories not listed might be hazardous and could cause serious personal injury. 12 Fig.
ASSEMBLY UNPACKING WARNING: This product requires assembly. Do not connect to power supply until assembly is complete. Failure to comply could result in accidental starting and possible serious personal injury. Carefully lift miter saw from the carton by the “D” handle and the saw base, and place it on a level work surface. WARNING: Do not use this product if any parts on the Loose Parts List are already assembled to your product when you unpack it.
ASSEMBLY TRACE HOLES AT THESE LOCATIONS FOR HOLE PATTERN WARNING: Always make sure the compound miter saw is securely mounted to a workbench or an approved workstand. Failure to heed this warning can result in serious personal injury. MOUNTING HOLES See Figure 8. If not using a stand, the saw should be mounted to a firm supporting surface such as a workbench. Four bolt holes have been provided in the saw base for this purpose. Each of the four mounting holes should be bolted securely using 1/4 in.
ASSEMBLY 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.
ASSEMBLY WORK CLAMP See Figure 12. The work clamp provides greater control by clamping the workpiece to the fence or the 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 of the work clamp to secure the workpiece prior to making the cut.
ASSEMBLY DANGER: Laser radiation. Avoid direct eye contact with light source. WARNING: Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure. ALIGNING THE LASER GUIDE LINE See Figures 13 and 14. Lock out the switch trigger by installing a padlock (not included). Draw a line on the workpiece. When the laser guide switch is turned on it will generate a red line on the work surface.
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. Never operate the saw without all guards securely in place and in good operating condition. SQUARING THE BLADE TO THE FENCE See Figures 15 - 18. Unplug the saw. Pull the saw arm all the way down and engage the lock pin to hold the saw arm in transport position. Unlock the miter lock lever.
ASSEMBLY SQUARING THE BLADE TO THE MITER TABLE BEVEL LOCK KNOB See Figures 19 - 22. Unplug the saw. Pull the saw arm all the way down and engage the lock pin to hold the saw arm in transport position. MITER FENCE Unlock the miter lock lever. Rotate the miter table until the pointer aligns with zero on the miter scale. Lock the miter lock. Loosen bevel lock knob and set saw arm at 0° bevel (blade set 90° to miter table). Tighten bevel lock knob.
OPERATION CUTTING WITH YOUR COMPOUND MITER SAW WARNING: Do not allow familiarity with tools to make you careless. 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.
OPERATION NOTE: You can quickly locate 0°, 15°, 22-1/2°, 31.62° and 45° left or right as you rotate the control arm. The miter table will seat itself in one of the detent index points, located in base. MITER CUT SWITCH LOCK Lock the miter lock. 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.
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. COMPOUND MITER CUT 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 29.

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 the 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- 30.00° B- 0.
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.
OPERATION Bevel Angle Setting Type of Cut 33.85° Left side, inside corner 1. Top edge of molding against fence 2. Miter table set right 31.62° 3. Save left end of cut 33.85° Right side, inside corner 1. Bottom edge of molding against fence 2. Miter table set left 31.62° 3. Save left end of cut 33.85° Left side, outside corner 1. Bottom edge of molding against fence 2. Miter table set left 31.62° 3. Save right end of cut 33.85° Right side, outside corner 1. Top edge of molding against fence 2.
ADJUSTMENTS POSITIVE STOP ADJUSTMENTS WARNING: See Figure 33. NOTE: These adjustments were made at the factory and normally do not require readjustment. 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. To adjust: Unplug the saw. The compound miter saw has been adjusted at the factory for making very accurate cuts.
ADJUSTMENTS LASER DANGER: LOCK SCREW Laser radiation. Avoid direct eye contact with light source. WARNING: Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure. TO ADJUST THE LASER GUIDE See Figures 34 - 36. Set miter and bevel angles to 0º. Use the work clamp or a C-clamp to secure a piece of scrap wood. Plug the saw into the power source and make a slight cut to score the wood.
ADJUSTMENTS TO ADJUST THE MITER LOCK LEVER See Figure 37. Prior to squaring the saw blade to the fence, check and adjust the miter lock lever, if needed. In the “locked” position, the action of fully locking the miter lock lever should feel tight and secure. Considerable effort should be required to move the miter table. If the table moves easily when in the “locked” position, an adjustment of the miter lock lever is required. To adjust: Unplug the saw. UNLOCK Lock the miter lock lever completely.
MAINTENANCE WARNING: BRUSH CAP When servicing, use only identical replacement parts. Use of any other parts may create a hazard or cause product damage. BRUSH ASSEMBLY 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.
