SAFETY GUIDELINES - DEFINITIONS It is important for you to read and understand this manual. The information it contains relates to protecting YOUR SAFETY and PREVENTING PROBLEMS. The symbols below are used to help you recognize this information. Indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury. Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.
GENERAL SAFETY RULES READ AND UNDERSTAND ALL WARNINGS AND OPERATING INSTRUCTIONS BEFORE USING THIS EQUIPMENT. Failure to follow all instructions listed below, may result in electric shock, fire, and/or serious personal injury or property damage. IMPORTANT SAFETY INSTRUCTIONS 1. 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. 14. 2.
ADDITIONAL SPECIFIC SAFETY RULES FAILURE TO FOLLOW THESE RULES MAY RESULT IN SERIOUS PERSONAL INJURY. 1. DO NOT OPERATE THIS MACHINE UNTIL it is assembled and installed according to the instructions. 2. OBTAIN ADVICE from your supervisor, instructor, or another qualified person if you are not familiar with the operation of this machine. 3. FOLLOW ALL WIRING CODES and recommended electrical connections. 4 MOUNT THE TOOL SECURELY to a stable supporting surface prior to operation 5.
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 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.
UNPACKING AND CLEANING Carefully unpack the machine and all loose items from the shipping container(s). Remove the protective coating from all unpainted surfaces. This coating may be removed with a soft cloth moistened with kerosene (do not use acetone, gasoline or lacquer thinner for this purpose). After cleaning, cover the unpainted surfaces with a good quality household floor paste wax.
FASTENING THE MACHINE TO THE SUPPORTING SURFACE Before operating your compound miter saw, mount it to a sturdy workbench or other supporting surface. Four holes are provided, two of which are shown at (A) Fig. 5. When frequently moving the saw from place to place, mount the saw to a 3/4″ piece of plywood. The tool can then be easily moved from place to place and the plywood can be clamped to a supporting surface using “C” clamps. A Fig.
TABLE EXTENSION WINGS This machine uses two table extension wings to help stabilize the machine, and to help support long or wide workpieces. To attach the table extension wings: Remove the screws on the ends of the extension rods (A) Fig. 8. Attach the table extension wings (A) Fig. 9 to the extension rods and secure with the screws just removed. To utilize the supports, pull them out to their full length (Fig. 10). DUST BAG Insert the dust spout (A) Fig.
OPERATION OPERATIONAL CONTROLS AND ADJUSTMENTS STARTING AND STOPPING THE MITER SAW A B Fig. 15 Fig. 14 To start the miter saw, depress the switch trigger (A) Fig. 14. To stop the miter saw, release the switch trigger. This saw is equipped with an automatic electric blade brake. As soon as the switch trigger (A) Fig. 14 is released, the electric brake activates and stops the blade in seconds. A TURNING SAW BLADE CAN BE DANGEROUS. AFTER COMPLETING THE CUT, RELEASE THE SWITCH TRIGGER (A) FIG.
A B D D C Fig. 17 Fig. 18 TILTING THE CUTTINGHEAD FOR BEVEL CUTTING The cuttinghead of your compound miter saw can be tilted to cut any bevel angle from a 90° straight cut off to a 45° left bevel angle. Loosen bevel lock handle (A) Fig. 19, tilt the cutting arm to the desired angle, and tighten the lock handle (A). B A Positive stops are provided to rapidly position the saw blade at 90° and 45° to the table. Refer to the section of this manual titled “ADJUSTING 90° AND 45° DEGREE BEVEL STOPS.
D A C B Fig. 21 Fig. 22 B G F A E Fig. 23 Fig. 24 ADJUSTING THE 90° AND 45° BEVEL STOPS DISCONNECT THE MACHINE FROM THE POWER SOURCE. 1. Lock the machine in the “down” position (Fig. 21). 2. Place one end of a square (B) Fig. 21 on the table and the other end against the blade. Check to see if the blade is 90° to the table. 3. If an adjustment is necessary, loosen the locknut (B) Fig. 22. Turn the screw (C) until the head of the screw contacts the casting (D) when the blade is 90° to the table.
NOTE: Check to see that the blade is 90 degrees to the fence. 2. Move the table to the 90 degree straight cut-off position. Make sure that the bottom of the index lever (C) Fig. 28 is engaged in the 0 degree positive stop. Tighten the lock handle (D) Fig. 28. 3. Clamp the workpiece and make a cut (Fig. 26). 4. Use a square to see if the piece of wood was cut at 90° (Fig. 27). 5. To adjust, loosen the lock handle (D) Fig. 28 one turn. Loosen the locknut (B) and turn eccentric nut (C) right or left.
AUXILIARY WOOD FENCE When performing multiple or repetitive operations that result in small cut-off pieces (one inch or less), the saw blade can catch the cut-off pieces and project them out of the machine or into the blade guard and housing, causing damage or injury. To limit the risk, mount an auxiliary wood fence on your saw (Fig. 31). A Fig. 31 WORK SUPPORT EXTENSIONS For support when cutting long pieces, construct a work support extension. Fig.
GENERAL CUTTING OPERATIONS Your machine can cut: 1. standard 2 x 4’s lying flat or on edge at 45° right and left miter angles (Figs. 33 and 34). 2. standard 2 x 6’s in the 90° straight cut-off position in one pass (Fig. 35). 3. standard 4 x 4’s in one pass (Fig. 36). 4. crown molding and other bevel-type cuts (Fig. 37). 5. various sizes of plastic pipe (Fig. 38). Fig. 33 Fig. 34 Fig. 35 Fig. 36 Fig. 37 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 blades. Do not use carbide-tipped blades with deep gullets. They can deflect and contact the guard. Use only 10″″ diameter saw blades that are rated for 5000 RPM or higher and have 5/8″″ diameter arbor holes.
BRUSH INSPECTION AND REPLACEMENT Brush life varies, depending 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 every 10 hours of use until replacement is necessary. To inspect the brushes: DISCONNECT THE MACHINE FROM THE POWER SOURCE. 1. Open the brush holders (A) Fig. 48, located on either side of the motor housing. 2. Remove the brushes (B) Fig. 49. 3.
