OPERATION Kickback can be caused by any action that pinches the blade in the wood such as: WARNING: Do not allow familiarity with tools to make you careless. Remember that a careless fraction of a second is sufficient to inflict severe injury. WARNING: Always wear eye protection with side shields marked to comply with ANSI Z87.1. Failure to do so could result in objects being thrown into your eyes, resulting in possible serious injury.
OPERATION CUTTING AIDS See Figure 22. Push sticks are devices that may be used for pushing a workpiece through the blade in any rip cut. When making non-through cuts or ripping narrow stock, always use a push stick, push block, and/or featherboard so your hands do not come within 3 inches of the saw blade. They can be made in various sizes and shapes from scrap wood and used in a specific project.
OPERATION FEATHERBOARD WARNING: A featherboard is a device used to help control the workpiece by holding it securely against the table or fence. Featherboards are especially useful when ripping small workpieces and for completing non-through cuts. The end is angled with a number of short kerfs to give a friction hold on the workpiece and locked in place on the table with a C-clamp. Test to ensure it can resist kickback. Mount the featherboard in front of the saw blade.
OPERATION TYPES OF CUTS See Figure 27. There are six basic cuts: 1) the cross cut, 2) the rip cut, 3) the miter cut, 4) the bevel cross cut, 5) the bevel rip cut, and 6) the compound (bevel) miter cut. All other cuts are combinations of these basic six. Operating procedures for making each kind of cut are given later in this section. 1 CROSS CUT WARNING: Always make sure the blade guard and anti-kickback pawls are in place and working properly when making these cuts to avoid possible injury.
OPERATION TO CHANGE BLADE DEPTH GULLET See Figure 28. The blade depth should be set so that the outer points of the blade are higher than the workpiece by approximately 1/8 in. to 1/4 in. but the lowest points (gullets) are below the top surface. Raise the blade by turning the height/bevel adjusting handwheel clockwise or lower it by turning the handwheel counterclockwise. TO CHANGE BLADE ANGLE (BEVEL) See Figured 29 - 30. NOTE: A 90° cut has a 0° bevel and a 45° cut has a 45° bevel. Fig.
OPERATION WARNING: CLAMP SCREW To reduce the risk of injury, always make sure the rip fence is parallel to the blade before beginning any operation. TO USE THE RIP FENCE LOCKING LEVER See Figure 31. Place the rear lip on the rear of the saw table and pull slightly toward the front of the unit. Lower the front end of the rip fence onto the guide surfaces on top of the front rail. With the rip fence flat on the saw table, push the fence towards the front rail to align the fence to the saw table.
OPERATION TO USE THE MITER GAUGE MITER GAUGE BODY See Figure 32. The miter gauge provides greater accuracy in angled cuts. For very close tolerances, test cuts are recommended. MITER GAUGE There are two miter gauge grooves, one on either side of the blade. When making a 90° cross cut, you can use either miter gauge groove.
OPERATION HEELING (PARALLELING) THE BLADE TO THE MITER GAUGE GROOVE ADJUSTING SCREWS (2) See Figures 36 - 38. WARNING: RIGHT MITER GAUGE GROOVE The blade must be parallel to the miter gauge groove so the wood does not bind resulting in kickback. Failure to do so could result in serious personal injury. COMBINATION SQUARE Do not loosen any screws for this adjustment until you have checked with a square and made test cuts to be sure adjustments are necessary.
OPERATION MAKING CUTS CROSS CUT This table saw can perform a variety of cuts that are not all mentioned in this manual. DO NOT attempt to make any cuts not covered here unless you are thoroughly familiar with the proper procedures and necessary accessories. Your local library has many books on table saw usage and specialized woodworking procedures for your reference.
OPERATION MAKING A RIP CUT RIP CUT See Figure 41. WARNING: RIP FENCE BLADE Make sure the blade guard assembly is installed and working properly to avoid serious possible injury. Set the blade to the correct depth for the workpiece. Position the rip fence the desired distance from the blade for the cut and securely lock the handle. Make sure the wood is clear of the blade before turning on the saw.
OPERATION MAKING A BEVEL CROSS CUT VIEWED FROM THE FRONT, BELOW THE TABLE SAW See Figures 43 - 44. WARNING: Make sure the blade guard assembly is installed and working properly to avoid possible serious injury. Remove the rip fence. Unlock the bevel locking lever. Adjust the bevel angle to the desired setting. Lock the bevel locking lever. Set the blade to the correct depth for the workpiece. Set the miter gauge to 0° and tighten the lock knob.
OPERATION Position the workpiece flat on the table with the edge flush against the rip fence. Let the blade build up to full speed before feeding the workpiece into the blade. BEVEL RIP CUT BLADE ANGLED Once the blade has made contact with the workpiece, use the hand closest to the rip fence to guide it. Make sure the edge of the workpiece remains in solid contact with both the rip fence and the surface of the table.
OPERATION MAKING A LARGE PANEL CUT LARGE PANEL CUT See Figure 47. Make sure the saw is properly secured to a work surface to avoid tipping from the weight of a large panel. RIP FENCE WARNING: Make sure the blade guard assembly is installed and working properly to avoid possible serious injury. SUPPORT WARNING: Never make freehand cuts (cuts without the miter gauge or rip fence). Unguided workpieces can result in serious injury.
OPERATION MAKING A DADO CUT NON-THROUGH CUT See Figure 49. An optional dado throat plate is required for this procedure (see the Accessories section of this manual and check with the retailer where the table saw was purchased). All blades and dado sets must not be rated less than the speed of this tool. This saw is designed for 5/8 in. dado cuts. With the purchase of an optional dado throat plate, it can be used with a 6 in. stack dado (up to width of 3/4 in.).
ADJUSTMENTS WARNING: BLADE WRENCH BLADE WRENCH Before performing any adjustment, make sure the tool is unplugged from the power supply and the switch is in the OFF position. Failure to heed this warning could result in serious personal injury. The table saw has been adjusted at the factory for making very accurate cuts. However, some of the components might have been jarred out of alignment during shipping. Also, over a period of time, readjustment will probably become necessary due to wear.
ADJUSTMENTS TO SET THE BLADE AT 0° AND 45° BLADE See Figures 53 - 54. The angle settings of the saw have been set at the factory and, unless damaged in shipping, should not require setting during assembly. After extensive use, they may need to be checked. COMBINATION SQUARE Unplug the saw. Raise the blade. 0° ADJUSTMENT SCREW Remove the blade guard assembly. If the blade is not perfectly vertical (0°): Unlock the bevel locking lever. Loosen the 0° adjustment screw.
ADJUSTMENTS TO CHECK THE ALIGNMENT OF THE RIP FENCE TO THE BLADE RIP FENCE BLADE See Figure 55. Unplug the saw. Raise the locking lever to permit the rip fence to be moved. Place a framing square beside the blade and move the rip fence up to the square. Take the dimension on the rip scale. Move the fence back and turn the framing square 180° to check the other side. If the two dimensions are not the same, loosen the two bolts on the fence and align it. Retighten the two bolts.
