SAFETY GUIDELINES - DEFINITIONS This manual contains information that is important for you to know and understand. This information relates to protecting YOUR SAFETY and PREVENTING EQUIPMENT PROBLEMS. To help you recognize this information, we use the symbols to the right. Please read the manual and pay attention to these sections. Indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury.
FAILURE TO FOLLOW THESE RULES MAY RESULT IN SERIOUS PERSONAL INJURY. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. FOR YOUR OWN SAFETY, READ THE INSTRUCTION MANUAL BEFORE OPERATING THE MACHINE. Learning the machine’s application, limitations, and specific hazards will greatly minimize the possibility of accidents and injury. USE CERTIFIED SAFETY EQUIPMENT. Eye protection equipment should comply with ANSI Z87.1 standards, hearing equipment should comply with ANSI S3.
ADDITIONAL SAFETY RULES FOR MITER SAWS FAILURE TO FOLLOW THESE RULES MAY RESULT IN SERIOUS PERSONAL INJURY. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. 16. DO NOT OPERATE THIS MACHINE until it is completely assembled and installed according to the instructions. A machine incorrectly assembled can cause serious injury. OBTAIN ADVICE from your supervisor, instructor, or another qualified person if you are not thoroughly familiar with the operation of this machine. Knowledge is safety.
POWER CONNECTIONS A separate electrical circuit should be used for your machines. This circuit should not be less than #12 wire and should be protected with a 20 Amp time lag fuse. If an extension cord is used, use only 3-wire extension cords which have 3prong grounding type plugs and matching receptacle which will accept the machine’s plug.
EXTENSION CORDS Use proper extension cords. Make sure your extension cord is in good condition and is a 3-wire extension cord which has a 3-prong grounding type plug and matching receptacle which will accept the machine’s plug. When using an extension cord, be sure to use one heavy enough to carry the current of the machine. An undersized cord will cause a drop in line voltage, resulting in loss of power and overheating. Fig. D-1, shows the correct gauge to use depending on the cord length.

ASSEMBLY FOR YOUR OWN SAFETY, DO NOT CONNECT THE MACHINE TO THE POWER SOURCE UNTIL THE MACHINE IS COMPLETELY ASSEMBLED AND YOU READ AND UNDERSTAND THE ENTIRE INSTRUCTION MANUAL. ATTACHING MITER SAW ARM TO BASE B DISCONNECT MACHINE FROM POWER SOURCE. 1. Align the bevel lock handle screw (A) Fig. 2, on the miter saw arm with the bevel hub (B) on the base. A 2. Thread the bevel lock handle screw (A) Fig. 2, into the bevel hub (B) by turning the bevel handle knob (K) Fig. 2A and tighten securely. Fig.
2. Rotate table to the left until index stop engages with the 90 degree positive stop (Fig. 5). Tighten table lock handle (A). A Fig. 5 MOVING CUTTINGHEAD TO THE UP POSITION A 1. Push down on switch handle (A) Fig. 6, and pull out cuttinghead lock knob (B). B Fig. 6 2. Move the cuttinghead (C) to the up position (Fig. 7). C Fig. 7 ATTACHING DUST BAG C A Attach dust bag (A) Fig. 8 to the dust spout (B) making sure the wire ring (C) is engaged with the ridge in the spout. Fig.
FASTENING MACHINE TO SUPPORTING SURFACE Before operating your compound miter saw, make sure it is firmly mounted to a sturdy workbench or other supporting surface. Four holes are provided, two of which are shown at (A) Fig. 9. A When frequently moving the saw from place to place, we suggest that the saw be mounted to a 3/4″ piece of plywood. The tool can then be easily moved from place to place and the plywood clamped to the supporting surface using “C” clamps. A Fig.
LOCKING SWITCH IN THE “OFF” POSITION IMPORTANT: When the miter saw is not in use, the switch should be locked in the OFF position using a padlock (B) Fig. 13, with a 3/16" diameter shackle to prevent unauthorized use of the saw. B Fig. 13 ROTATING TABLE FOR MITER CUTTING B Your miter saw will cut any angle from a straight 90 degree cut to 47 degrees right and left. Loosen lock handle (A) Fig. 14 one or two turns, depress index lever (B), and move the control arm to the desired angle.
ADJUSTING POINTER If it becomes necessary to adjust the pointer (E) Fig. 17, loosen screw (G), adjust the pointer (E) accordingly, and tighten screw. G E LOCKING CUTTINGHEAD IN THE DOWN POSITION Fig. 17 When transporting the saw, the cuttinghead should always be locked in the down position. Lower the cutting arm (A) Fig. 18, and push in plunger (B) until other end of plunger (B) engages with hole in cutting arm. IMPORTANT: CARRYING THE MACHINE BY THE SWITCH HANDLE WILL CAUSE MISALIGNMENT.
A A C B Fig. 21 Fig. 22 ADJUSTING BLADE PARALLEL TO TABLE SLOT B DISCONNECT MACHINE FROM POWER SOURCE. 1. Lower the cutting arm. The saw blade (A) Fig. 22 should be parallel to the left edge (B) of the table opening. 2. If an adjustment is necessary, loosen three screws (C) Fig. 22 and move the cutting arm until the blade is parallel with the left edge (B) of the table opening and centered in the slot. Then tighten the three screws (C). A Fig.
ADJUSTING 90 AND 45 DEGREE BEVEL STOPS DISCONNECT MACHINE FROM POWER SOURCE. 1. Loosen bevel lock handle and move the cutting arm all the way to the right. Tighten the bevel lock handle. 2. Place one end of a square (A) Fig. 26 on the table and the other end against the blade. Check to see if the blade is 90 degrees to the table (Fig. 26). A Fig. 26 3. If an adjustment is necessary, loosen locknut (B) Fig.
ADJUSTING TENSION OF CUTTINGHEAD RETURN SPRING B A The tension of the cuttinghead return spring has been adjusted at the factory so that the cuttinghead returns to the up position after a cut has been made. If it becomes necessary to re-adjust the spring tension, proceed as follows: DISCONNECT MACHINE FROM POWER SOURCE. Fig. 30 Loosen locknut (A) Fig. 30 and turn screw (B) clockwise to increase or counterclockwise to decrease the spring tension.
Fig. 33A Fig. 33B GENERAL CUTTING OPERATIONS 1. Your machine has the capacity to cut standard 2 x 4’s lying flat or on edge, at the 45 degree right and left miter angles (Fig. 33A). 2. A standard 2 x 6 can be cut in the 90 degree straight cut-off position in one pass (Fig. 33C) or at 45 degree right or left miter angles (Fig. 33C). Fig. 33C 3. Cutting a standard 4 x 4 can be accomplished with one pass (Fig. 33D). 4.
CUTTING ALUMINUM Aluminum extrusions such as used for making aluminum screens and storm windows can easily be cut with your compound miter saw. When cutting aluminum extrusions, or other sections that can be cut with a saw blade and are within the capacity of the machine, position the material so the blade is cutting through the smallest cross-section (Fig. 34). The wrong way to cut aluminum angles is illustrated in Fig. 35. Be sure to apply a stick wax to the blade before cutting aluminum stock.
CUTTING CROWN MOULDING A B One of the many features of your saw is the ease of cutting crown moulding.The following is an example of cutting both inside and outside corners on 52/38 degree wall angle crown moulding. NOTE: When cutting 45 degree wall angle crown moulding, the following procedure for inside and outside corners is the same with the exception that the bevel position will always be at 30 degrees and the miter position will be 35.25 degrees to the right or left. Fig. 38 1.
MAINTENANCE CHANGING THE BLADE A B USE ONLY CROSS-CUTTING SAW BLADES. WHEN USING CARBIDE TIPPED BLADES, DO NOT USE BLADES WITH DEEP GULLETS AS THEY CAN DEFLECT AND CONTACT THE GUARD. USE ONLY 10″″ DIAMETER SAW BLADES WHICH ARE RATED FOR 5200 RPM OR HIGHER AND HAVE 5/8″″ DIAMETER ARBOR HOLES. Fig. 42 DISCONNECT MACHINE FROM POWER SOURCE. 1. Remove screw (A) Fig. 42 and rotate cover (B) to the rear (Fig. 43). B Fig. 43 2. To remove the saw blade, insert hex wrench (C) Fig.
BRUSH INSPECTION AND REPLACEMENT B Brush life varies. It depends on the load on the motor. Check the brushes after the first 50 hours of use for a new machine or after a new set of brushes has been installed. After the first check, examine them after about 10 hours of use until such time that replacement is necessary. To inspect the brushes, proceed as follows: A A DISCONNECT MACHINE FROM POWER SOURCE. Fig. 46 1. Remove three screws (A) Fig. 46 and remove motor cover (B). 2.
