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 MINIMUM GAUGE EXTENSION CORD RECOMMENDED SIZES FOR USE WITH STATIONARY ELECTRIC MACHINES 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.

ASSEMBLY ASSEMBLY TOOLS REQUIRED 3mm hex wrench (supplied) ASSEMBLY TIME ESTIMATE Assembly time for this product will be about 30 minutes to an hour. MOVING CUTTINGHEAD TO THE UP POSITION B 1. Push down slightly on the cuttinghead (B) Fig. 4 while pulling out the cuttinghead lockpin (A). Move the cuttinghead (B) to the up position. 2. Fig. 5, illustrates the lockpin (A) pulled out and the cuttinghead (B) in the up position.
MOVING TABLE TO THE 0° CUT-OFF POSITION 1. Loosen locking knob (A) Fig. 6 by turning counterclockwise. Depress lever (B) and rotate table (C) to the 0° straight cut-off position, release lever (B), and tighten locking knob (A). 2. Fig. 7 illustrates the table (C) in the 0° straight cut-off position. 3. For proper operation and adjustment of the table, refer to sections, “ROTATING TABLE FOR MITER CUTTING”, and “ADJUSTING SLIDING FIT BETWEEN MOVABLE TABLE AND BASE.” B C A Fig. 6 C Fig.
ATTACHING THE FENCE SLIDE 1. Position the sliding fence (E) Fig. 7C, on top of saw fence slide support(J). Install thumb screw (K) and set screw (L) but do not tighten at this time. 2. Slide fence (E) on fence slide support (J) Fig. 7D. Tighten set screw (L) with hex wrench (M) until it contacts the fence slide support, then loosen one turn. The purpose of this set screw is to prevent the sliding fence from coming completely off the slide support.
FASTENING MACHINE TO SUPPORTING SURFACE A A Before operating your compound miter saw, firmly mount it to a workbench or other supporting surface. Four holes, (A) Fig. 9, are provided for fastening the saw to a supporting surface. When frequently moving the saw from place to place, mount the saw to a 3/4” piece of plywood. The saw can then be easily moved from place to place and the plywood can be clamped to the supporting surface using “C” clamps. A A Fig.
ROTATING TABLE FOR MITER CUTTING B 1. The compound miter saw will cut any angle from a straight 0° cut to 47° right and left. Turn locking knob (A) Fig. 12 counterclockwise, depress lock lever (B), and rotate table to desired position. 2. The compound miter saw is equipped with positive stops at the 0° cut-off position and at the 22.5°, 31.62°, and 45° left and right positions. 3. The center line, (C) Fig. 13, on the cursor indicates the actual angle of cut. Each scale line (B) represents 1°.
ADJUSTING FENCE 90° TO BLADE IMPORTANT: BEFORE MAKING THIS ADJUSTMENT, SET THE BLADE AT 0° TO THE TABLE. SEE SECTION “ADJUSTING 0° AND 45° BEVEL POSITIVE STOPS.” 1. 2. 3. 4. 5. C DISCONNECT THE MACHINE FROM THE POWER SOURCE. Rotate the movable table so that the blade is 90° to the fence and the positive stop is set for 0°. Place one end of a framing square (A) Fig. 15 against the front of the fence (B) and the other end against the blade (C), with the blade locked in the down position.
TILTING CUTTINGHEAD FOR BEVEL CUTTING IMPORTANT: MOVE THE SLIDING FENCE TO THE LEFT TO PROVIDE CLEARANCE FOR THE BLADE AND GUARD. THE DEGREES OF TILT DETERMINES HOW FAR TO MOVE THE SLIDING FENCE. REFER TO THE SECTION “ADJUSTING SLIDING FENCE.” 1. B DISCONNECT THE MACHINE FROM THE POWER SOURCE. 2. The cuttinghead of your compound miter saw can be tilted to cut any bevel angle from a 90° straight cutoff to a 45° left bevel angle. Loosen bevel lock handle (A) Fig.
ADJUSTING 0° AND 45° BEVEL POSITIVE STOPS 1. DISCONNECT THE FROM THE POWER SOURCE. A MACHINE 2. Adjust saw so that both bevel and miter pointers are set at 0°. Tighten bevel lock handle and lock cuttinghead in down position. 3. Place one end of a square (A) Fig. 23 on the table and the other end against the blade. The blade should be set at 90° to the table. 4. If an adjustment is necessary, loosen bevel handle (H) Fig. 24.
ADJUSTING THE TENSION OF CUTTINGHEAD RETURN SPRING The tension of the cuttinghead return spring has been adjusted at the factory in order that the cuttinghead returns to the up position after a cut has been made. To adjust the spring tension, turn adjusting screw (A) Fig. 28, clockwise to increase or counterclockwise to decrease the spring tension. C B MAKE SURE SAW CUTTINGHEAD RETURNS FREELY TO THE FULL RAISED POSITION TO ENSURE THE LOWER BLADE GUARD FULLY ENCLOSES THE BLADE. Fig.
ADJUSTING EXTENSION WINGS AND STOP BLOCK A The stop block can be used for cuting off several pieces to the same length. The edge of the workpiece (A) Fig. 30B should rest against the stop block as shown. To adjust the stop block to the proper measurement, loosen the wing screw (B) Fig. 30A, reset the stop block in the desired location and tighten the wing screw. C B If the stop block (A) Fig. 30C is not needed, it can be moved out of the way so both extension wings can be used to support a long piece.
fence (A) and (B) Fig. 31. This auxiliary fence is constructed of straight wood approximately 1/2” thick by 3” high by 16 inches long as shown at (B); and 1/2” thick by 5” high by 17” long (A) Fig. 31. CORRECT NOTE: The auxiliary fence (A) is used only with the saw blade in the 0° bevel position (90°) to the table. The auxiliary fence must be removed for all bevel cuts (blade tilted). FENCE BLADE CUTTING ALUMINUM Fig.
CUTTING CROWN MOULDING One of the many features of the saw is the ease of cutting crown moulding. The following is an example of cutting both inside and outside corners on 52°/38° wall angle crown moulding. 1. Move the table to the 31.62° right miter position and lock the table in position. NOTE: A positive stop is provided to find this angle quickly. 2. Tilt the saw blade to the 33.86° left bevel position and tighten bevel lock handle.
TROUBLESHOOTING For assistance with your machine, visit our website at www.deltamachinery.com for a list of service centers or call the DELTA Machinery help line at 1-800-223-7278 (In Canada call 1-800-463-3582). MAINTENANCE CHANGING THE BLADE USE ONLY CROSS-CUTTING SAW BLADES. DO NOT USE BLADES WITH DEEP GULLETS AS THEY CAN DEFLECT AND CONTACT GUARD 1. Use only 12" diameter blades with 1" arbor holes that are rated for 4000 RPM or higher. 2. DISCONNECT THE MACHINE FROM THE POWER SOURCE. 3.
KEEP TOOL CLEAN Periodically blow out all air passages with dry compressed air. Clean all plastic parts with a soft damp cloth. NEVER use solvents to clean plastic parts. They could possibly dissolve or otherwise damage the material. CAUTION: WEAR SAFETY GLASSES WHILE USING COMPRESSED AIR. FAILURE TO START Should your tool fail to start, check to make sure the prongs on the cord plug are making good contact with the outlet. Also, check for blown fuses or open circuit breakers in the line.
