OPERATION 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 safety goggles or safety glasses with side shields when operating tools. Failure to do so could result in objects being thrown into your eyes resulting in possible serious injury. WARNING: Do not use any attachments or accessories not recommended by the manufacturer of this tool.
OPERATION TYPES OF CUTS See Figure 17. 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 See Figure 18. 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. Push the bevel locking lever to the left for elevation mode. Raise the blade by turning the height adjusting handwheel counterclockwise or lower it by turning the handle clockwise. GULLET TO CHANGE BLADE ANGLE See Figure 19. Unlock the bevel locking lever.
OPERATION TO USE THE RIP FENCE See Figure 21. Place the front lip on the front rail and push slightly toward the rear of the unit. Lower the rear of the rip fence onto the guide surfaces on top of the rear rail. Push the locking lever down to automatically align and secure the fence. Check for a smooth gliding action. If adjustments are needed, see To Check the Alignment of the Rip Fence to the Blade in the Adjustment section of this manual.
OPERATION HEELING (PARALLELING) THE BLADE TO THE MITER GAUGE GROOVE SCREWS See Figures 25 - 27 . WARNING: The blade must parallel the miter gauge slot so the wood does not bind resulting in kickback. Failure to do so could result in serious personal injury. Do not loosen any screws for this adjustment until you have checked with a combination square and made test cuts to be sure adjusments are necessary. Once the screws are loosened, these items must be reset. Unplug your saw. Lift the blade guard.
OPERATION MAKING CUTS The blade provided with your saw is a high-quality combination blade suitable for ripping and crosscut operations. SWITCH KEY WARNING: Do not use blades rated less than the speed of this tool. Failure to heed this warning could result in personal injury. Use the miter gauge when making cross, miter, bevel, and compound miter cuts. To secure the angle, lock the miter gauge in place by twisting the lock knob clockwise. Always tighten the lock knob securely in place before use.
OPERATION MAKING A MITER CUT MITER CUT See Figure 30. It is recommended you make test cuts on scrap wood. BLADE GUARD ASSEMBLY MITER GAUGE WARNING: Remove the rip fence by lifting the locking handle. Set the miter gauge to the desired angle and tighten the lock knob. Make sure the wood is clear of the blade before turning on the saw. Let the blade build up to full speed before moving the workpiece into the blade. Feed the workpiece into the blade until the cut has been completed.
OPERATION MAKING A BEVEL CROSS CUT BEVEL CROSS CUT See Figure 32. It is recommended that you place the piece to be saved on the left side of the blade and that you make a test cut on scrap wood. MITER GAUGE WARNING: Make sure the blade guard assembly is installed and working properly to avoid serious personal injury. Unlock the bevel locking lever. Remove the rip fence by lifting the locking handle. Turn the bevel handwheel until the bevel indicator is at the desired angle.
OPERATION MAKING A COMPOUND MITER CUT NON-THROUGH CUT It is recommended that you place the piece to be saved on the left side of the blade and that you make a test cut on scrap wood first. FEATHERBOARD WARNING: Make sure the blade guard assembly is securely installed and working properly to avoid serious personal injury. Remove the rip fence by lifting the lock down handle. Unlock the bevel locking lever. Adjust the bevel angle to the desired setting.
OPERATION MAKING A DADO CUT WARNING: Never feed wood with your hands when making any nonthrough cut such as rabbets or dadoes. WARNING: When making a non-through cut, the cutter is covered by the workpiece during most of the cut. Be alert to the exposed cutter at the start and finish of every cut to avoid the risk of serious personal injury. When the cut is made, turn the saw OFF ( ). Wait for the blade to come to a complete stop before removing the workpiece. Unplug your saw.
ADJUSTMENTS Before performing any adjustment, make sure the tool is unplugged from the power supply. 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 BLADE INDICATOR AND BEVEL STOPS AT 0° OR 45° (SQUARING THE BLADE) See Figure 38. The angle settings of your saw have been set at the factory and, unless damaged in shipping, should not require setting during assembly. After extensive use, it may need to be checked. Unplug the saw. If the blade is not perfectly vertical (0°), loosen the nuts on the stop bolt inside the cabinet, position the blade, adjust the stop bolt, then retighten nut. See Figure 38, insert.
ADJUSTMENTS TO CHECK THE ALIGNMENT OF THE RIP FENCE TO THE BLADE RIP FENCE See Figure 40. Raise the locking handle 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 screws on the fence and align it. Retighten the two screws.
TROUBLE SHOOTING PROBLEM Excess Vibration. POSSIBLE CAUSE 1. Blade is out of balance. 2. Blade is warped or damaged. 3. Saw is not mounted securely to a level work surface.
