– 18 – English AVOID KICKBACK by pushing forward on the section of the workpiece that passes between the blade and the fence. Never perform any freehand operations. Fig. AA NOTE: Always use a push stick. When width of the rip is narrower than 2 in the push stick cannot be used because the guard will interfere…therefore, use the auxiliary fence so the push stick can be used as shown on page 24. 7. Keep your thumbs off the table top. When both of your thumbs touch the front edge of the table (2), finish the cut with a push stick. To make an additional push stick, use the pattern on page 24. 8. The push stick (3) should always be used. (Fig. BB) 9. Continue pushing the workpiece with the push stick (3) until it passes through the blade guard and clears the rear of the table. 10.Never pull the piece back when the blade is turning. Turn the switch OFF. When the blade completely stops, you can then remove the workpiece. Fig. BB CUTTING OPERATIONS There are two basic types of cuts: ripping and crosscutting. Ripping is cutting along the length and the grain of the workpiece. Crosscutting is cutting either across the width or across the grain of the workpiece. Neither ripping nor crosscutting may be done safely freehand. Ripping requires the use of the rip fence, and crosscutting requires the miter gauge. Before using the saw each and every time, check the following: 1. The blade is tightened to the arbor. 2. The bevel angle lock knob is tight. 3. If ripping, the fence is locked into position & is parallel to the miter gauge groove. 4. The blade guard is in place and working properly. 5. Safety glasses are being worn. The failure to adhere to these common safety rules, and those printed in the front of this manual, can greatly increase the likelihood of injury. RIPPING (FIG. AA, BB) To prevent serious injury: • Never use a miter gauge when ripping. • Never use more than one rip fence during a single cut. • Do not allow familiarity or frequent use of your table saw to cause careless mistakes. Remember that even a careless fraction of a second is enough to cause a severe injury. • Keep both hands away from the blade and clear from the path of the blade. • The workpiece must have a straight edge against the fence and must not be warped, twisted, or bowed when ripping. 1. Remove the miter gauge and store it in the “storage” compartment in the base of the saw. 2. Secure the rip fence to the table. 3. Raise the blade so it is about 1/8 in higher than the top of the workpiece. 4. Place the workpiece flat on the table and against the fence. Keep the workpiece away from the blade. 5. Turn the saw ON and wait for the blade to come to full speed. 6. Slowly feed the workpiece into the blade by pushing forward only on the workpiece section (1) that will pass between the blade and the fence. (Fig. AA) WARNING WARNING WARNING 2 1 3 1
– 19 – English Fig. CC USING WOOD FACING ON THE MITER GAUGE (Fig. DD) Slots are provided in the miter gauge for attaching an auxiliary facing (1) to make it easier to cut very long or short pieces. Select a suitable piece of smooth wood, drill two holes through it and attach it to the miter gauge with screws. Make sure the facing does not interfere with the proper operation of the sawblade guard. When cutting long workpieces, you can make a simple outfeed support by clamping a piece of plywood to a sawhorse. Fig. DD BEVEL CROSSCUTTING (FIG. EE) This cutting operation is the same as crosscutting except the blade is at bevel angle other than 0°. Always work to the right side of the blade during this type of cut. The miter gauge (1) must be in the right side groove (2) because the bevel angle may cause the blade guard to interfere with the cut if used on the left side groove. 1. Adjust the blade (3) to the desired angle, and tighten the blade bevel lock knob. 2. Tighten miter lock handle at 90°. 3. Hold workpiece firmly against the face of the miter gauge (1) throughout the cutting operation. NOTE: When tilting the blade to 45°, the miter gauge handle will hit the blade guard. Fig. EE BEVEL RIPPING This cut is the same as ripping except the blade bevel angle is set to an angle other than 0º. RIPPING SMALL PIECES To avoid injury from the blade contact, never make cuts narrower than 1/2 in wide. 1. It is unsafe to rip small pieces. Instead, rip a larger piece to obtain the size of the desired piece. 2. When a small width is to be ripped and your hand cannot safely pass between the blade and the rip fence, use one or more push sticks to move the workpiece. Always use a push stick during ripping operations. CROSSCUTTING (FIG. CC) To prevent serious injury: • Do not allow familiarity or frequent use of your table saw to cause careless mistakes. Remember that even a careless fraction of a second is enough to cause a severe injury. • Keep both hands away from the blade and the path of the blade. • Never attempt to pull the workpiece backwards during a cutting operation. This will cause kickback and serious injury to the user can occur. 1. Remove the rip fence and place the miter gauge in a miter gauge groove on the table. 2. Adjust the blade height so it is 1/8 in. higher than the top of the workpiece. 3. Hold the workpiece firmly against the miter gauge with the blade path in line with the desired cut location. Move the workpiece to 1in. distance from the blade. 4. Start the saw and wait for the blade (1) to come up to full speed. Never stand directly inline of the saw blade path, always stand to the side of the blade that you are cutting on. 5. Keep the workpiece (2) against the face of the miter gauge (3) and flat against the table. Then slowly push the workpiece through the blade. 6. Do not try to pull the workpiece back with the blade turning. Turn the switch OFF, and carefully slide the workpiece out when the blade is completely stopped. Always position the larger surface of the workpiece on the table when crosscutting and/or bevel crosscutting to avoid instability. WARNING WARNING 1 3 1 213 2
– 20 – English USING WOOD FACING ON THE RIP FENCE (FIG. HH) When performing some special cutting operations, add a wood facing (1) to either side of the rip fence (2). 1. Use a smooth & straight 3/4 in thick wood board (1) that is as long as the rip fence. 2. Attach the wood facing to the fence with wood screws (3) through the holes in the fence. A wood fence should be used when ripping material such as thin paneling to prevent the material from catching between the bottom of the fence and the table. Fig. HH AUXILIARY FENCE (FIG. II) Making the base: • Start with a piece of 3/8 in plywood at least 5-1/2 in wide or wider and 30 in long or longer. • Cut the piece to shape and size shown: Making the side: • Start with a piece of 3/4 in plywood at least 2-3/8 in wide or wider and 27 in long or longer • Cut the piece to shape and size shown: Putting it together: • Put the pieces together, as shown: Make sure the screw heads do not stick out from the bottom of the base, they must be flush or recessed. The bottom must be flat and smooth enough to rest on the saw table without rocking. Fig. II COMPOUND MITER CROSSCUTTING (FIG. FF) This sawing operation is combining a miter angle with a bevel angle. Always work to the right side of the blade during this type of cut. The miter gauge (3) must be in the right side groove because the bevel angle may cause the blade guard to interfere with the cut if used on the left side groove. When tilting the workpiece to 45° and push it toward the blade, the blade guard may hit the blade. To avoid injury, stop the work at that time. 1. Set the miter gauge (3) to the desired angle. 2. Place the miter gauge (3) in the right side groove (2) of the table. 3. Set the blade (1) bevel to the desired bevel angle and tighten the blade bevel lock knob. 4. Hold workpiece firmly against the face of the miter gauge (3) throughout the cutting operation. Fig. FF MITER CUTS (FIG. GG) This sawing operation is the same as crosscutting except the miter gauge is locked at an angle other than 90°. 1. Set the blade (1) to 0° bevel angle and tighten the blade bevel lock knob. 2. Set the miter gauge (3) at the desired miter angle and lock in position by tightening the miter gauge locking handle. 3. Hold the workpiece (2) firmly against the face of the miter gauge throughout the cutting operation.
