. Keep bystanders, children, and visitors away while operating a power tool. Distractions can cause you to lose control. Protect others in the work area from debris such as chips and sparks. Provide barriers or shields as needed. ELECTRICAL SAFETY 4. Grounded tools must be plugged into an outlet properly installed and grounded in accordance with all codes and ordinances. Never remove the grounding prong or modify the plug in any way. Do not use any adapter plugs.
12. Avoid accidental starting. Be sure the Power Switch is off before plugging in. Carrying power tools with your finger on the Power Switch, or plugging in power tools with the Power Switch on, invites accidents. 13. Remove adjusting keys or wrenches before turning the power tool on. A wrench or a key that is left attached to a rotating part of the power tool may result in personal injury. 14. Do not overreach. Keep proper footing and balance at all times.
25. When servicing a tool, use only identical replacement parts. Follow instructions in the “Inspection, Maintenance, And Cleaning” section of this manual. Use of unauthorized parts or failure to follow maintenance instructions may create a risk of electric shock or injury. SPECIFIC SAFETY RULES 1. Maintain a safe working environment. Keep the work area well lit. Make sure there is adequate surrounding workspace. Always keep the work area free of obstructions, grease, oil, trash, and other debris.
13. Causes and operator prevention of “kickback”: Kickback is a sudden reaction to a pinched, bound, or misaligned Saw Blade, causing an uncontrolled Saw to lift up and out of the workpiece toward the operator. When the Saw Blade is pinched or bound tightly by the kerf closing down, the Saw Blade stalls and the Motor reaction drives the tool rapidly toward the operator.
16. Turn off the Saw and allow the Saw Blade to stop on its own if the Saw Blade is to be backed out of an uncompleted cut. 17. Industrial applications must follow OSHA requirements. 18. The Laser on the Miter Saw is rated as a Class 2. Do not stare directly at the Laser beam. A hazard may exist if you deliberately stare into the beam. Never aim the Laser beam at any person, animal, or an object other than the workpiece. 19.
29. WARNING! People with pacemakers should consult their physician(s) before using this product. Operation of electrical equipment in close proximity to a heart pacemaker could cause interference to or failure of the pacemaker. 30. WARNING! Some dust created by power sanding, sawing, grinding, drilling, and other construction activities, contain chemicals known (to the State of California) to cause cancer, birth defects or other reproductive harm.
3. Your tool must be plugged into an appropriate outlet, properly installed and grounded in accordance with all codes and ordinances. The plug and outlet should look like those in the following illustration. (See Figure A.) FIGURE A DOUBLE INSULATED TOOLS: TOOLS WITH TWO PRONG PLUGS 4. Tools marked “Double Insulated” do not require grounding.
EXTENSION CORDS 1. Double Insulated tools can use either a two or three wire extension cord. 2. As the distance from the supply outlet increases, you must use a heavier gauge extension cord. Using extension cords with inadequately sized wire causes a serious drop in voltage, resulting in loss of power and possible tool damage. (See Figure C) 3. The smaller the gauge number of the wire, the greater the capacity of the cord.

BLADE CASE (54) ARROW SAW BLADE (4) ARROW SAW TEETH POINTING DOWNWARD FIGURE D 4. CAUTION! The Lock Pin (128) should always be activated in the “locked down” position when the Saw is not being used and when the Saw is being transported. The Lock Pin should be activated in the “locked up” position when changing Saw Blades. NEVER use the Lock Pin in any cutting operation.

9. Unscrew and remove the Hex Head Bolt (1). Then, remove the Spindle Washer (2) and Flange (3). (See Figure I.) SPINDLE WASHER (2) HEX HEAD BOLT (1) FIGURE I FLANGE (3) 10. Release pressure on the Safety Lock Grip (42). (See Figure H.) 11. Wearing heavy duty work gloves to avoid accidental cuts, remove the old Saw Blade (4). (See Figure J.) SAW BLADE (4) FIGURE J 12. Install the new Saw Blade (4), making sure the teeth of the Saw Blade are point- ing downward. (See Figure D.) 13.
To Assemble/Adjust Additional Accessories: 1. A workpiece Clamp Assembly (96, 99, 101, 109, 111) can be installed by inserting the Assembly into the hole located in the Guide Fence (97). Once inserted, lock the Assembly in place with a Wing Screw (103). To clamp the workpiece to the Work Table (87) of the Miter Saw, turn the Adjusting Knob (111) clockwise. (See Figure K.) 2.
The Safety Cover: 1. The transparent Safety Cover (72) automatically rotates to cover the Saw Blade (4) when the Blade Case (54) is lifted. When the Blade Case is lowered, the Safety Cover rotates back out of the way. (See Figure L.) 2. Do not disconnect or remove the Safety Cover (72). Do not operate the Miter Saw if the Safety Cover is damaged or missing. (See Figure L.) 3.
SAFETY BUTTON (37) SWITCH LEVER (41) FIGURE M The Laser Assembly: 1. The Miter Saw is equipped with a Laser Assembly (148) for improved cutting accuracy and convenience. (See Figure N.) 2. The Laser Assembly (148) is powered by two “AAA” Batteries (included). To install the Batteries, open the Battery Box Cap (137). Insert two AAA Batteries into the Battery Box (143), making sure to match the polarity of the Batteries with the polarity signs (+ and -) as shown in the Battery Box. (See Figure N.) 3.
The Elbow Dust Chute: 1. The Elbow Dust Chute (66) exhausts the wood chips and saw dust when the Miter Saw is in operation. (See Figure O.) 2. The outside diameter of the Elbow Dust Chute is 1-3/8”. Attach Dust Collection Bag (158) to the Elbow Dust Chute or attach vacuum hose (not included). It is recommended that only a qualified technician attach a vacuum hose. (See Figure O.
make sure the Saw Blade (4) does not contact the bottom of the Work Table (87) or any other part of the Saw Base. (See Figure P) LONG BOLT (133B) SHORT BOLT (133A) KERF BOARD (151) FIGURE P 7. WORK TABLE (87) SAW BLADE (4) If the Saw Blade (4) touches the Work Table (87) or any other part of the Saw Base, turn the two Bolts (133A,133B) clockwise to raise the Saw Blade slightly until it clears. (See Figure P.) To Adjust The Miter Angle: 1.
To Adjust The Angle Of Cut: 1. WARNING! Prior to performing this procedure, make sure the Power Cord of the Miter Saw is unplugged from its electrical outlet. 2. The bevel angle (or Saw Blade tilt capacity) may be adjusted from 0 - 45 degrees to the left. To do so, loosen the Lock Lever (122) located at the rear of the Miter Saw. (See Figure R.) 3. Tilt the Arm Holder (132) until the desired bevel angle of cut is achieved as indi- cated on the Scale Plate (155).
8. When the Saw Blade (4) is turning at full speed, slowly bring down the Motor Housing (31) to complete the cut. NOTE: Feed the Saw Blade into the workpiece gradually. Do not force the machine to remove material faster than it was designed to cut. 9. When cutting a large workpiece, make sure its entire length is properly supported. If necessary, use a roller stand (not included) with a larger workpiece. 10.
3. Daily: With a soft brush, cloth, or vacuum, remove all dust and debris from the Miter Saw. Then, use a premium quality, lightweight machine oil to lubricate all moving parts except the Saw Blade (4). 4. To replace the Motor Carbon Brushes: It may become necessary at sometime to replace the two Carbon Brushes (26) when the Motor performance decreases, or stops working completely. The Carbon Brushes are located on each side of the Motor Housing (31). To do so, remove the two Brush Holder Caps (23).
