    Make certain the work area is well lighted and that a proper exhaust system is used to minimize dust. Powermatic recommends the use of anti-skid floor strips on the floor area where the operator normally stands and that each machine’s work area be marked off. Provide adequate work space around the machine.

  • Page 9: Mounting Extension Wings

    MOUNTING EXTENSION WINGS Mount the cast iron extension wings using six 1/2-13 x 1-1/4 hex head screws and six 1/2 lock wash- ers. (These are shipped already inserted into the holes.) See Figure 2. Have an assistant hold the wing up to the table, and insert the screws and washers.

OPTIONAL WOOD EXTENSION TABLE For instructions on mounting the accessory wood ex- tension table, or router table, consult your Accu-Fence manual.

  • Page 11: Electrical Connections

    ELECTRICAL CONNECTIONS WARNING: All electrical connections should be done by a qualified electrician. Failure to comply may result in serious injury. The machine must be properly grounded. Consult the electrical schematics on pages 34-36 for proper wiring of the table saw. ADJUSTMENTS FIGURE 10 CAUTION: Disconnect machine from...

  • Page 12: Tilt Stop Adjustment

    TILT STOP ADJUSTMENT Using a combination square, check the 90 degree (zero) and 45 degree stops as shown in Figure 14. Adjust stop positions if required, using the stop screws as shown. Check the accuracy of the pointer at 90 degrees (zero) and readjust if required.

  • Page 13: Splitter Alignment

    SPLITTER ALIGNMENT One of the most critical adjustments to help avoid kick- back is the splitter adjustment. It should be checked and re-adjusted, if required, after each blade change. Lift the mitre gauge bar slightly out of its slot. Place a combination square against the side of the raised up miter gauge bar and slide the scale against the top of the blade tooth and against the splitter as shown in Figure 17.

  • Page 14: Tilting Mechanism

    If the saw arm has been relocated, the table may have to be realigned so as to provide clearance between the saw blade and table insert slot. The splitter will also have to be realigned. NOTE: The saw arm setscrew must be tight to avoid the possibility of movement which could cause the blade to hit the insert.

  • Page 15: Operating Instructions

    OPERATING INSTRUCTIONS FOR TABLE SAWS (NOTE: Your table saw may not resemble exactly the machine shown in these photos, but the proce- dures will be identical.) Familiarize yourself with the location and opera- tion of all controls and adjustments and the use of accessories such as the mitre gauge and rip fence.

  • Page 16: Rip Sawing

    - Where possible, keep your face and body out of line with potential kickbacks including when starting or stopping the machine. Dull, badly set, improper, or improperly filed cut- ting tools and cutting tools with gum or resin adher- ing to them can cause accidents. Never use a cracked saw blade.
  • Page 17 Always use the saw guard, splitter and anti-kick- back pawls. Make sure the splitter is properly aligned. When wood is cut along the grain, the kerf tends to close and bind on the blade and kickbacks can oc- cur. NOTE: A caution decal is installed on the guard and splitter assembly warning of the hazard of misalign- ment.

  • Page 18: Resawing

    RESAWING Resawing is a ripping operation in which thick boards are cut into thinner ones. Narrow boards up to 3" can be resawed in one pass. Wider boards up to 6" must be resawed in two passes. In resawing wider boards, adjust the blade height so as to overlap the two cuts by 1/2"...

  • Page 19: Bevel & Mitre Operations

    Stop rods can be used in the holes provided in the mitre gauge for repetitive work of equal length. Do not use a stop rod on the free end of a workpiece. It should be used on the side of the mitre gauge oppo- site the saw blade.

  • Page 20: Safety Devices

    The guard, splitter, and anti-kickback pawls supplied with the saw should be used for all cutting operations where they can be used. When performing opera- tions where the guard can not be used, as in some dadoing operations, alternative safety precautions should be taken.
