It can cause your hand • to contact the blade, resulting in serious personal injury. Stay outofthe bladepathand turnswitch offimmediatelyifblade bindsorstalls. • ALWAYS PUSH THE WORKPIECE never pull it toward the saw. USE A SUPPORT FOR THE SIDES AND BACK OF THE SAW TABLE when sawing wide or long workpieces to minimize the risk of blade pinching and kickback. Use a sturdy "outrigger" support to prevent tipping if a table extension more than 24 inches long is attached to the saw. CUT ONLY WOOD, PLASTIC OR WOOD-LIKE MATERIALS. Do not cut metal. • ALWAYS TURN OFF SAW before disconnecting it, to avoid accidental starting when reconnecting to the power supply. NEVER leave the saw unattended while connected to a power source. • BEFORE CHANGING THE SETUP, REMOVING COVERS, GUARDS, OR BLADE; unplug the saw and remove the switch key. • KEEP TOOL DRY, CLEAN, AND FREE FROM OIL AND GREASE. Always use a clean cloth when cleaning. Never use brake fluids, gasoline, petroleum-based products, or any solvents to clean tool. • BEFORE MAKING A CUT, be sure all adjustments are secure. NEVER cut more than one piece at a time. DO NOT STACK more than one workpiece on the saw table at a time. • DO NOT REMOVE THE SAW'S BLADE GUARD. Never operate the saw with the blade guard removed. Make sure all guards are operating properly before each use. KEEP BLADES CLEAN, SHARP AND WITH SUFFICIENT SET. Sharp blades minimize stalling and kickback. Keep blades free of rust, grease, and pitch. ,_k USE THE RIP FENCE. Always use a fence or straight edge guide when ripping. • BE SURE THE BLADE PATH IS FREE OF NAILS. Inspect for and remove all nails from lumber before cutting. • BE SURE THE BLADE CLEARS THE WORKPIECE. Never start the saw with the blade touching the stock. • KEEP HANDS AWAY FROM CUTTING AREA. Do not reach underneath work or in blade cutting path with your hands and fingers for any reason. Always turn the power off when cut is complete. • USE A PUSHBLOCK OR PUSHSTICK in rip mode for workpieces so small that your fingers go under the blade guard. NEVER TOUCH BLADE or other moving parts during use, for any reason. WARNING: Blade coasts after being turned off. USE ONLY OUTDOOR EXTENSION CORDS. Use only extension cords with the marking "Acceptable for use with outdoor appliances; store indoors while not in use." Use extension cords with an electrical rating not less than the saw's rating. Always disconnect the extension cord from the outlet before disconnecting the product from the extension cord. • NEVER PERFORM ANY OPERATION FREEHAND. Always place the workpiece to be cut on the saw table and position it firmly against the fence as a backstop. • INSPECT TOOL CORDS AND EXTENSION CORDS PERIODICALLY and, if damaged, have repaired by a qualified service technician at a Sears repair center. Stay constantly aware of cord location and keep it well away from the moving blade. • DO NOT ABUSE CORD. Never yank the cord to disconnect it from receptacle. Keep the cord from heat, oil, and sharp edges. • SAVE THESE INSTRUCTIONS. Refer to them frequently and use to instruct other users. If you loan someone this tool, loan them these instructions also. SAVE THESE INSTRUCTIONS CRRF:I'$HRN° RADIALSAW 315.273731 when ripping; DO NOT FEED THE MATERIAL TOO QUICKLY. Do not force the workpiece against the blade. DO NOT USE A PERSON AS A SUBSTITUTE FOR A TABLE if additional support is needed. Use a support the same height as the table. • ALLOW THE MOTOR TO COME UP TO FULL SPEED before starting a cut to avoid blade binding or stalling. 6 • SECURE THE SAW. Firmly bolt the saw to the leg stand to keep the saw from tipping, walking, or sliding. • DO NOT SET UP WORK WITH THE BLADE SPINNING. Keep the saw power off until you are ready to use it. • • • • • the saw to allow enough room on all sides so neither the operator nor a visitor stands in line with the sawblade. • NEVER LOWER AN UNLOCKED REVOLVING CUTTING TOOL. A(ways lock the carriage lock knob before lowering the blade. AVOID HEELING by adjusting the saw blade so it exactly parallels the fence during ripping operations. AVOID GRABBING in rip mode by keeping the saw blade correctly adjusted and by feeding the work from the infeed side (opposite the antikickback pawls). SHUT OFF THE POWER TO FREE A JAMMED GUARD. Press the switch off before putting your hands near the blade. Wait for the blade to stop, then free the guard. • LOCK THE SAW BEFORE MOVING IT. Secure the radial arm with the arm lock knob. Secure the carriage with the carriage lock knob. AVOID PINCHING by using a riving knife and sharp saw blade. Keep the work positioned firmly against the fence. • USE IN-RIP WHENEVER POSSIBLE by positioning the work so the blade is between (inside) the column and the motor. • NEVER ADJUST GUARD, PAWLS, OR BLADE WITHOUT DISCONNECTING THE POWER. POSITION THE WORKPIECE WITH THE FINISHED SIDE DOWN. If the anti-kickback pawls catch the wood to stop kickback, they could mar the top surface or cause splintering. POSITION THE WORKPIECE SO NO ONE MUST STAND IN LINE WITH THE BLADE. If kickback or climb occurs, a helper, operator, or observer in the sawblade path could be seriously injured. • POSITION THE CUT SO THE WASTE PART FALLS OFF. Never use a length stop on the free end of the workpiece. Never apply force to the free end or hold it while the sawblade is rotating. • KEEP THE SAW BLADE PATH CLEAR. Position RIP ONLY WORKPIECES LONGER THAN THE BLADE'S DIAMETER. Never rip a piece of wood that is shorter than the diameter of the blade. • ,_ BEFORE CUTTING, position and tighten the blade guard and anti-kickback pawls. Test the pawls to make sure they would stop kickback if it started. Keep the points sharp. Always turn off the switch and unplug the cord before freeing a jammed blade, tightening a loose blade, or repositioning the guard or pawls. ,_L NEVER CUT MORE THAN ONE PIECE OF WOOD AT A TIME. The feed will be uneven and could cause the blade to pick up one or more pieces and cause serious injury. WARNING: In a rip cut, holding the cut-off edge behind the blade can cause the cut edges to pinch, risking kickback. It could cause the blade to climb over the front edge of the wood and contact your hand. TURN OFF SAW IF A STRANGE NOISE OR HEAVY VIBRATION OCCURS. Immediately turn off the saw, locate the source, and correct the problem before using the saw further. POSITION THE CUT SO THE BLADE WILL NOT EXTEND BEYOND THE EDGE OF THE TABLE. BEFORE STARTING EACH CUT, check that no play exists in the carriage. Be sure the arm, yoke and bevel locks and clamps are tight. Verify the blade, all handles, blade washers, and blade nuts are secure. • BEFORE MAKING A CUT, test the upper and lower blade guards for free movement up and down. Position the nose of the guard to just clear the workpiece. • AVOID KICKBACK AND POSSIBLE INJURY by preventing heeling, grabbing, and pinching. CAUTION: Do not turn the motor switch on and off rapidly. This can loosen the sawblade. KEEP THE GUARDS IN PLACE AND THE WORK SURFACE CLEAR DURING A CUT. Small objects or wood slivers can ricochet from the blade into the fence and back toward the operator. If the blade loosens slivers, remove them with a stick, not your hand. IN A RIP CUT, DO NOT LET GO OF THE WORKPIECE UNTIL THE CUT IS COMPLETE. When the workpiece is fed into the blade, push the workpiece all the way past the blade. 7 I:RRIq'._HRH ° RADIALSAW315.273731 EXTENSION CORDS GROUNDING Use only 3-wire extension cords that have 3-prong grounding plugs and 3-pole receptacles that accept the tool's plug. When using a power tool at a considerable distance from the power source, use an extension cord heavy enough to carry the current that the tool will draw.

Use the chart provided below to determine the minimum wire size required in an extension cord. Only round jacketed cords listed by Underwriter's Laboratories (UL) should be used. Length of Extension Cord Do not modify the plug provided. If it will not fit the outlet, have the proper outlet installed by a qualified electrician. Improper connection of the equipmentgrounding conductor can result in a risk of electric shock. The conductor with insulation having an outer surface that is green with or without yellow stripes is the equipment-grounding conductor. If repair or replacement of the electric cord or plug is necessary, do not connect the equipment-grounding conductor to a live terminal. Wire Size (A.W.G.) Up to 25 feet 26-100 feet 14 12 When working with the tool outdoors, use an extension cord that is designed for outside use. This is indicated by the letters WA on the cord's jacket. Check with a qualified electrician or service personnel if the grounding instructions are not completely understood, or if in doubt as to whether the tool is properly grounded. Before using an extension cord, inspect it for loose or exposed wires and cut or worn insulation. ,_ CAUTION: Keep the cord away from the cutting area and position the cord so that it will not be caught on lumber, tools, or other objects during cutting operations. ELECTRICAL Repair or replace a damaged or worn cord immediately. This tool is intended for use on a circuit that has an outlet like the one shown in Figure 1. It also has a grounding pin like the one shown. CONNECTION Your Sears Craftsman Radial Arm Saw is powered by a precision built electric motor. It should be connected to a power supply that is 120 volts, 60 Hz, AC only (normal household current). It should be connected to a 240 volt power supply only if it has been reset according to the instructions in this manual. The motor has been set at the factory for 120 volts; if it is reconnected to operate at 240 volts, the main power cord plug and any receptacle must be replaced with devices rated for 240 volts. This tool will not operate on direct current (DC). A substantial voltage drop will cause a loss of power and the motor will overheat. If the saw does not operate when plugged into an outlet, double check the power supply. GROUNDING PIN COVEROFGROUNDED OUTLETBOX SPEED AND WIRING The no-load speed of your saw is approximately 3,600 rpm. This speed is not constant. For voltage, the wiring in a shop is as important as the motor's horsepower rating. A line intended only for lights cannot properly carry a power tool motor. Wire that is heavy enough for a short distance will be too light for a greater distance. A line that can support one power tool may not be able to support two or three tools.

See Figure 8A. OVERVIEW -The main operating components include the column, the arm, and the yoke assembly (yoke, motor, and blade), and their operation is summarized in the paragraph below. Safety features and control functions are given also. Spending a few minutes reviewing the illustrations and features list below and on the following pages to locate these items will make assembly easier. Safety features include the control cut device, the removable switch key, and the blade guard assembly. Never operate the saw without ensuring these safety features are in place and functioning correctly. On a radial saw, "cross cut" means a cut parallel to the arm, and a "rip cut" is perpendicular to the arm. There are several ways to make cuts, depending on the size and material of the workpiece and the end result desired. METHOD OF OPERATION: The column at the back of the saw supports the radial arm. The arm can be raised or lowered to change the blade height or swiveled left and right for a miter cut. A yoke fits into a carriage on the arm, which can travel back and forward. The yoke supports the yoke assembly (motor, blade, and blade guard) and can be pivoted so the blade faces right, front, or left. The motor can be rotated to change the blade angle. Before attempting to use your saw, familiarize yourself with all operating features and safety requirements of your Sears Craftsman Radial Arm Saw. *Shown on following pages CONTROL CUTHOUSlNG YOKE ARM LOCKKNOB CARRIAGE AND COVER SWITCHAND KEY COLUMN BLADE AND BLADEGUARD MOTOR ELEVATING HANDWHEEL Fig. 8A CRR_T=_MRN _RADIALSAW315.273731 16 FEATURES LIST BEVEL LOCK LEVER - Sets and locks blade angle.

The yoke clamp keeps the yoke from rotating on the carriage when you want the saw blade to be stationary. Use this procedure to check and set the yoke clamp. • Release the yoke lock handle (below the arm on the right side) so the motor can be rotated. • Swivel the motor slightly. It should be at an angle in between one of the preset positive stop angles. YOKE LEG Fig. 16B CR_F;TSMRN ° RADIALSAW 315.273731 24 SETTING THE BEVEL LOCK LEVER See Figures 17A -17C. The bevel lock lever locks the blade at desired angles other than the preset positive stop angles. The bevel lock lever is preset at the factory but may need readjustment after shipping or extended use. Check for overtightness or looseness and make any necessary adjustments as follows: The bevel lock lever is located on the front of the yoke assembly, near the bottom. It is attached to a clamp bolt that controls the amount of tightness. • Pull the bevel lock lever forward to unlock it. Use CLAMPBOLT e the bevel index knob (just under the handle) to rotate the motor approximately 30 °. Lock the bevel lock lever. • If the bevel lock lever is difficult to lock, the clamp bolt needs to be loosened. If the motor can be STAR WASHER forced out of position, the clamp bolt needs to be tightened. SOCKETSCREW • Remove the socket screw (under the bevel lock lever) and star washer with a 1/8 in. hex key. • Use the bevel lock handle as a wrench to tighten or loosen the clamp bolt. The clamp bolt has a righthanded thread. Tighten it left to right. • When the bolt is correctly set, remove the bevel lock lever from the clamp bolt and place it roughly parallel to the yoke assembly. • Replace the socket screw and star washer. Recheck the tightness of the bevel lock lever. Repeat the steps above until the motor is secure when locked, and the bevel lock lever fits squarely against the yoke assembly. I 1/8 in.

See Figures 19A - 19D. There should be no play, vertical or horizontal, in the arm relative to the column. If you can move the arm up, down or sideways when the arm lock knob is unlocked, use the following steps to tighten the arm. The purpose of this procedure is to check whether the inner column tube is snug in the housing and to remove any looseness. Looseness could result in a poor cut or difficulty in elevating the carriage. The column tube is the upper portion of the column and extends from the column support. Note: The arm should pivot only when the arm lock knob is unlocked and pulled forward to compress the spring. • Using a phillips screwdriver, remove the rear cover screws (2) and rear cover from the back of the arm. This uncovers the bolts on the column. • Tighten the top two bolts evenly until the arm is firm and there is no vertical or horizontal movement. • Also check the two bottom hex nuts. It is not necessary to tighten them as tight as the upper bolts. However they should be tightened even and snug. • Replace the rear cover and rear cover screws. • Tighten screws securely. Note: It is critical to remove all looseness with this procedure. If this procedure is not done correctly, following adjustments will be wrong and could result in machine damage. This procedure checks both the elevating action and the rotating action. If a check does not show looseness, do not perform the adjustment. REAR COVERSCREWS • If the arm is not at 0 ° (straight forward), release the arm lock knob, set the arm, and re-lock the arm lock knob. • Elevation check. To check the elevation movement, place your hand under the front of the radial arm. Press upward on the radial arm. There should be no play between the column tube and the column support. The whole assembly should move as one. See Figure 19A. COLUMN TUBE REAR COVER ARM HEXBOLT(2) COLUMN SUPPORT Fig. 19A HEXNUT(2) CR_FT_MRN °RADIAL SAW 315.273731 Fig. 18 26 • Elevation Rotation check: To check the rotation, hold the front of the arm with one hand and grasp the top of the column support with the other. Press the arm to the side. If there is play between the column support and the column tube, it needs to be adjusted. See Figure 19B. Adjustment COLUMNTUBE r \ COLUMNSUPPORT Fig. 19B Fig. 19C • • Elevation Adjustment. If the elevation check did not show any play between the column tube and the support, go to the rotation adjustment. Otherwise, raise and lower the arm with the elevating handwheel. Tighten the black screws on the right side of the column support by 1/16th to l/8th of a turn. Tighten the two silver screws on the left side slightly more. You will need two 1/2 in. wrenches or sockets. Turn the elevating handwheel again. If the column tube binds, loosen the silver and black screws and turn the handwheel again. See Figure 19C. • Rotation Adjustment. Using a 3/16 in. hex key, slightly tighten the two cap screws at the back of the column support (left side) until no play shows between the radial arm and the column. The cap screws are indicated by arrows. See Figure 19D. • Recheck the rotation by holding the front of the arm, grasping the top of the column support with the other, and pressing the arm to the side. Rotation Adjustment When the elevation is smooth, check for looseness again by pressing upward on the front of the arm. Repeat the previous step until elevation is smooth with no play between the column tube and the column support. CAP SCREWS Fig. 19D 27 rRRFT,_MRN° RADIALSAW 315.273731 ADJUSTING THE CARRIAGE BEARINGS • Use a 9/16 in. wrench to hold the eccentric screw (top of bearing) and a 1/2 in. wrench to loosen the nut below the bearing. • Turn the eccentric screw a partial turn as needed to tighten the bearing. • Retighten the nut and repeat the second step to test the tightness. Adjust it so the bearing turns even against resistance when the carriage is moved - but not so much that the carriage is difficult to move and return it to its rear position. • Repeat for the left rear bearing. See Figures 20A and 20B. Loose carriage bearings permit the blade to wander slightly while cutting, which will result in a poor cut and more wear and tear on the saw. Use the following steps to check for tightness and to then adjust the bearings if needed. • On the left side of the arm, remove the carriage lock knob, the carriage cover screws, and the carriage cover. • With one hand, grip the front bearing hard to keep it still, and pull the carriage forward with the other hand. The bearing should turn. If it stays still as the carriage is moved, it needs to be adjusted. Note: Adjust bearings on the left side only. Bearings on the right side do not adjust. • CARRIAGEBEARING Replace the carriage cover, carriage cover screws, and carriage lock knob. ECCENTRICSCREW GRASPAND HOLD CARRIAGEBEARING 9/16 in.

If not, adjust the table support until it is the same. Securely tighten the front screw. • Move the arm to the opposite side and repeat the above procedure. When the opposite side is level, recheck the first side to make sure that it is still accurate and even. • Return the saw and motor to normal height and position. See Figures 2fA and 2fB. The table supports must be perfectly level. • Pull the bevel lock lever forward to unlock it. Use the bevel index knob to rotate the motor so the arbor shaft points down. Lock the bevel lock lever. • Release the arm lock knob to angle the arm. Begin by positioning the arbor shaft over the back of the highest table support. Normally this is the left side. See Figure 21A. • Lock the arm lock knob and the carriage lock knob. • Using one of the blade wrenches as a feeler gage, place it on the table support below the arbor shaft. • With the elevating handwheel, carefully lower the motor until the shaft just touches the wrench. The wrench should move with only slight resistance. Securely tighten the back screw on the table support. • Without changing the elevation, move the arm to place the blade arbor over the front of table support. See Figure 21B.

Fig. 27 To complete setting up your saw, continue with the Adjustment procedures. The adjustments should be checked regularly, depending on usage. Your saw will provide accurate cuts with fine tolerances as long as you protect the accuracy with frequent alignment checks. The radial arm saw can perform a wide range of high quality cuts. The final step will be connecting the control cut device. The control cut device offers many benefits. As it increases operator control, it eliminates the risk in a cross cut of the saw "climbing" out and over the workpiece at the operator. Feed control of the blade as it cuts through the workpiece increases, as does the accuracy of the cut. The following adjustments need to be completed before the control cut device is connected. Your radial arm saw is designed to perform a variety of complex cuts with fine tolerances. A weekly alignment check ensures that your saw can perform with precision. It takes about ten minutes and the results is better performance and a longer life for your saw. _ Perform the checks in the order given. If you miss an adjustment, go back to the missed adjustment and repeat all steps from that point forward. CRR$:I'$HR_J _RADIALSAW 315.273731 SCREWS 34 CAUTION: Failure to check alignments and perform the adjustments in the initial set up or on a frequent basis can result in poor performance or machine damage. ALIGNING THE ARM FOR CROSS CUTS • Release the arm lock knob. Position the arm straight forward (0 °) and leave it unlocked. • Lower the arm with the elevating handwheel until the saw blade just clears the front table. Lock the yoke lock handle (right side of saw, below yoke) and the bevel lock lever. • Place the framing square on the table and position one edge of the square firmly against the back edge of the table. Position the other leg of the square against the blade until it rests beside but not touching a tooth. With a pencil, mark beside this tooth. • Slowly move the yoke assembly forward and backward along the arm and against the square without rotating the blade. If the mark moves into or away from the square, adjust the arm with the following steps. • At the back of the column, loosen the three setscrews with a 3/16 in. hex key and position the arm as needed to align with the framing square. • Lock the arm lock knob and retighten the three setscrews. Recheck the cross cut travel with the blade against the framing square. • Set the miter indicator on top of the column to 0 °. • Replace the fence, spacer table, rear table, and table clamps. See Figures 28A - 28C. This procedure checks whether the arm is exactly 0 ° for cross cut travel by checking the blade against the table and the miter indicator. Remove the rear table, spacer table, and fence, but leave the front table in place. You will need a framing square, a 3/16 in. hex key, and a pencil. ,_ WARNING: Be sure the saw is unplugged before performing these adjustments. Accidental start-up could result in serious personal injury. • First check the framing square by fitting one side against the back edge of the table.

Replace the carriage cover and screws, then replace the spring and carriage lock knob. • Set the speed thumbwheel, using the chart on the label. If you are unsure of the proper speed setting, use the lowest setting. See Figure 33. Note: Before installing the control cut device, the yoke assembly will travel back and forward on the carriage by pulling the handle. After installing the control cut device, the power cord for the control cut device must be plugged in and switch trigger pressed to move the yoke assembly and carriage on the arm. _ WARNING: Do not install the control cut device until after all of the initial adjustments and alignments are made to prevent accidental starting of the saw that could result in serious personal injury. The control cut device offers many benefits. As it increases operator control, it eliminates the risk in a cross cut of the saw "climbing" out and over the workpiece at the operator. Feed control of the blade as it cuts through the workpiece increases, as does the accuracy of the cut. The control cut cable maintains a steady pull on the carriage assembly from the column. This tension keeps the assembly at the column, unless you squeeze the switch trigger in the handle. The switch trigger activates the motor to counter the pull of the cable. After a cut is completed, press the switch on the arm off, then release the switch trigger to prevent further forward motion. Hold the handle until the blade has BARREL FITTING stopped rotating. The yoke assembly will not roll forward unless you are squeezing the switch trigger. The control cut power cord is designed to operate on a single voltage AC circuit. The speed can be set with a thumbwheel on top of the handle. The three speed settings are described on the label located on the left side of the control cut housing. _ WARNING: Do not use the saw without the control cut and blade guards in place unless specifically instructed to do so. Otherwise uncontrolled contact with the blade could occur, resulting in personal injury. _ WARNING: Take great care when working with either cord to ensure you have the correct one. If you intend to unplug the main power cord but remove the control cut cord instead, the blade could be accidentally started and cause injury. CARRIAGE ASSEMBLY SOCKET rRRI:I'SH RN° RADIAL SAW 315.273731 40 Fig. 33 BASIC OPERATION ARM SAW OF THE RIP CUTS RADIAL In rip cuts, the yoke is rotated 90 ° left or right and locked in place. The wood must ride firmly against the rip fence. There are two orientations of rip cuts - the in-rip and the out-rip. The in-rip position provides better visibility. Out-rip cuts can also be made with the blade beveled. A radial arm saw can be used for straight-line cutting operations such as cross cutting, ripping, mitering, beveling, compound cutting, and resawing. It can make dado or molding cuts with special attachments. This saw is designed to cut wood and wood composition products only. In an in-rip cut, the yoke is rotated to the left, which puts the blade in between the column and the motor. The wood is fed from the right hand side. The three-prong plug must be plugged into a matching outlet that is properly installed and grounded according to all local codes and ordinances. Improper connection of the equipment can result in electric shock. Check with an electrician or service personnel if you are unsure about proper grounding. Do not modify the plug; if it will not fit the outlet, have the correct outlet installed by a qualified electrician. Refer to the Electrical page of this manual. TYPES In an out-rip cut, the blade is in front of the motor, and the wood is fed from the left. Out-rip cutting is recommended only when the blade is set 12 in. or more from the fence. ,_ OF CUTS See Figure 34. The radial saw makes cross cuts parallel with the arm (across the grain), and rip cuts square to the arm (with the grain). Each can be made with the blade vertical or beveled. Instructions for making each kind of cut are given later in this section. ,_ ,_iL WARNING: Always use a pushstick with small pieces of wood, and also to finish the cut when ripping a long narrow piece of wood, to prevent your hands from getting close to the blade. WARNING: All blades and cutting accessories must be rated for at least 5,000 rpm to prevent possible injury. CROSS WARNING: Always make sure the blade guard and anti-kickback pawls are in place and working properly when making rip cuts to avoid possible injury. Q _ _CROSS CUTS Cross cuts are made parallel to the arm. The blade is pulled along the length of the radial arm with the wood secured. __ There are several types of cross cuts. A cross cut shows 0° on the miter scale (arm straight) and 0 ° on the bevel scale (blade straight). A miter cut is made with the radial arm angled and the blade straight. A bevel cut is produced with the arm straight and the blade angled. MITERCUT BEVEL CUT A final type of cross cut is the compound cross cut. Both the arm and the blade are angled. Be thoroughly familiar with making cross cuts, bevel cuts, and miter cuts before trying a compound miter cut. 4_ Note: In cross cuts, the blade teeth point down as they strike the wood. In rip cuts, the teeth point up as they strike the wood. t_ ,_k CUT _ COMPOUNDCROSSCUT RIP CUT WARNING: NEVER make a cross cut with the short edge of the wood parallel to the fence. Kick back is likely to occur, causing the workpiece to be thrown back at you. Treat such a workpiece as a rip cut. ® ____BEVEL RIPCUT Fig. 34 41 CR_I:TSHRN° RADIAL SAW315.273731 SWITCH AND SWITCH L_ KEY See Figures 35-37. The main power switch has been placed on the front of the arm for easy access. The yellow switch key prevents accidental starting of the main power switch when saw is not being used. To activate the switch, insert the switch key and lift switch to ON position. To lock the switch once it has been pressed to OFF, remove the yellow key. Place the key in a location that is inaccessible to children and others not qualified to use the tool. CAUSES OF KICKBACK INSERTSWITCHKEY Kickback can occur when the blade stalls or binds, kicking the workpiece back toward you with great force and speed. If your hands are near the blade, they may be jerked loose and contact the blade. Obviously, kickback can cause serious injury and it is well worth using precautions to avoid the risks. Fig. 35 Kickback can be caused by any action that pinches the blade in the wood, such as the following: • Making a cut with incorrect blade depth • Sawing into knots or nails in the workpiece • Twisting the wood while making a cut • Failing to support work • Forcing a cut • Cutting warped or wet lumber • Misusing the saw • Not following correct operating procedures • Using the wrong blade for the type of cut • Cutting with a dull, gummed-up, or improperly set blade. AVOIDING Fig. 36 KICKBACK • Always use the correct blade depth setting. The outer point of the blade teeth should clear the lower surface of the workpiece by 1/8 in. to 1/4 in. when making these cuts. • Inspect the work for knots or nails before beginning a cut. Knock out any loose knots with a hammer. Never saw into a loose knot or nail. • Always use the fence when rip cutting. This helps prevent twisting the wood in the cut. • Always use clean, sharp, and properly-set blades. Never make cuts with dull blades. • To avoid pinching the blade, support the work properly before beginning a cut. • SWITCHON SWITCHOFF When making a cut, use steady, even pressure. Never force cuts. GRRFTSHRN ° RADIALSAW 315.273731 42 Fig. 37 • Do not cut wet or warped lumber. • Always hold your workpiece firmly with both hands or with pushsticks. Keep your body in a balanced position to be ready to resist kickback should it occur. Never stand directly in line with the blade. • Use the right type of blade for the cut being made. • Use the riving knife and anti-kickback pawls when performing rip cuts. CUTTING AIDS See Figures 38-40. Cutting aids are used to improve the setup and help make the operator's work safer and more accurate. They can be made from scrap wood and in various sizes and shapes for specific projects. The basic types are pushsticks, pushblocks, and featherboards. If the blade is set 2 in. or more from the fence, use a pushstick. Use a pushblock when the blade is between 1/2 in. and 2 in. from the fence. (If the cut is narrower than 1/2 in., use a different saw.) Refer to the drawings and instructions provided so you can make safer and more precise cuts. PUSHSTICKS Fig. 38 PUSHSTICKS See Figure 38. Pushsticks must be narrower than the workpiece, with a 90 ° notch in one end and shaped for a grip on the other end. 4;;>4;> PUSHBLOCKS See Figure 39. A pushblock has an upright handle with a base attached to the handle. Some pushblocks have a foot that extends down from the base and against the workpiece. The foot is attached to the base with glue only to prevent damage to the blade. FEATHERBOARDS PUSHBLOCKS Fig. 39 FEATHERBOARD Fig. 40 See Figure 40. Featherboards are used for large panels, along with an auxiliary table and a C-clamp. A featherboard has an angled end to fit against the edge of the workpiece. It is clamped in place so the workpiece moves between either the fence and the featherboard or the table and featherboard. Slots in the end of the featherboard help resist kickback and allow for variations in the width of the workpiece. _ Note: The Pushstick designs above are for illustration purposes only. They have not been drawn to scale. WARNING: Clamp the featherboard against the infeed side of the workpiece. If clamped behind the blade, it could squeeze the cut edges together, causing binding and kickback.

HANDLE BEVEL LOCK LEVER CLAMPS BEVELED AND ELEVATING HANDWHEEL Fig. 44 47 CRRFTSMRN ° RADIALSAW315.273731 RiP CUT HAZARDS AND PRECAUTIONS SETTING UP A RiP CUT See Figure 45. Two hazards are specifically associated with rip cutting: outfeed zone and wrong way feed. In the outfeed zone (behind the blade), the blade teeth point down. The slightest contact while the blade is still spinning can snag clothing, jewelry, the workpiece, or even skin, causing serious personal injury. A precise and safe rip cut requires a careful set up. Before setting up for in-rip or out-rip, especially for a bevel cut, try the workpiece in both placements. Check for stability, visibility, and control. Test which will give the best pushstick clearance. Wrong way feed occurs when the workpiece contacts the blade from the outfeed side. It is very hazardous and will jerk the workpiece violently. You could be cut if you are holding the workpiece. Instructions are given for an in-rip cut. At certain points, the instructions will vary for a bevel rip cut or an out-rip process and will be enclosed in parentheses (example). Figure 40 shows an out-rip setup. • Insert a solid fence with no kerfs. Use an auxiliary fence if the blade will be set only 1/2 in. to 2 in. from the fence. Tighten the table clamps. • If the arm is too low or too high, first lift the blade guard if the arm is too low, and turn the elevating handwheel at the front of the table. Set the blade to _11 WARNING: Failure to observe any of these precautions can result in serious injury. • The first precaution is, of course, simply to stay completely away from the outfeed zone. Keep hands away from the outfeed zone. • Point the anti-kickback pawls away from the blade teeth to snag a workpiece if the blade grabs. They should be positioned to rest lightly on the workpiece. The flat side of the pawls should be level and horizontal. • Set the riving knife to just clear the table. • Set the hold down in front of the blade to just clear the workpiece. • Start and finish your cut from the infeed side. • Push the workpiece past the pawls with pushblocks and pushsticks to finish the cut. • If the blade jams, turn the saw off with the switch on the arm, remove the yellow key, and wait for the blade to fully stop before freeing it. • Make sure the blade is parallel to the fence and the workpiece is not warped or twisted. • Make sure no pressure is applied to the workpiece on the outfeed side. • Make sure the blade guard is lowered and is working properly. just clear the kerf or table. • Change the blade angle if needed. Raise the plastic lower guard to keep it from jamming, release the bevel lock lever, and set the bevel indicator to zero. (For a bevel rip cut, set the bevel indicator to the desired angle.) Test the clearance on the guard. Retighten the bevel lock lever. RIP CUT SWITCH HOLD DOWN • Always set up the workpiece so the wider part of the wood is between the blade and the fence. This stabilizes the workpiece better. • Do not release the workpiece until it has moved past the pawls. Keep pushsticks firmly in place. • Use pushsticks and pushblocks, not your hands, when the trailing edge of the workpiece is within 3 in. of the blade. If the blade is set 2 in. or more ELEVATING HANDWHEEL INFEEDFOR IN RIPCUTTING from the fence, use a pushstick. Use a pushblock and auxiliary fence when the blade is between 2 in. and 1/2 in. from the fence. (If the cut is narrower than 1/2 in., use a different saw.) For large panel rip cuts, use a featherboard instead of pushblocks or pushsticks. See the section on Cutting Aids. CRAFTSMRN _RADIAL SAW 315.273731 Fig. 45 48 • Put the blade in the in-rip position between the motor and the column. Release the yoke lock handle and pivot the yoke to the left, with the yoke pivot latch on the right side of the arm. (Use the out-rip position only for rips 12 in. or more in width; pivot the yoke to the right so the motor is between the blade and column.) • Keep your other hand on the table and steady the workpiece against the fence. Keep that hand at least 8 in. from the blade. • If the blade cover does not automatically rise as the workpiece moves from the infeed to the outfeed side, stop the cut. Turn off the saw and adjust the blade cover so it rests on the workpiece. • Loosen the carriage lock knob. Place the blade the right distance from the fence for the cut and lock the knob. • • Cut a kerf. Turn the saw on with the switch on the arm. Lower the blade about 1/16 in. into the table to cut a shallow groove. Turn the saw off and remove the yellow key. When the end of the workpiece is still several inches from the blade, pick up the cutting aid you selected earlier. Push the wood with the pushstick or pushblock rather than your hand. • • Position the workpiece against the blade, from the front of the table. Lower the hold-down in front of the blade to just clear the workpiece. (For a bevel rip cut, place the workpiece directly under the guard rather than beside the blade.) Loosen the pawls and riving knife. Lower the riving knife to the table. Slide the workpiece back and lower the pawls so that one set rests on the workpiece. Lock the riving knife and pawls in place. (For a bevel rip cut, place the workpiece under the lower set of pawls.) • Remove the workpiece from the table. Set the push block, featherboard, or pushstick nearby. • Set up table extension(s) and supports. ,_ WARNING: Use a pushstick as the end of the workpiece nears the blade to reduce the risk of injury. • Push the wood completely through the blade to the outfeed, past the pawls. • When the work is completed, press the switch off and remove the key. ___ RIP CUT SWITCH WARNING: Never use a person to support workpieces. This can cause kickback and serious injury. Never have someone stand at the outfeed side. MAKING ANTI-KICKBACK PAWLS A RIP CUT See Figure 46. • Review the Hazards and Precautions page. • Do not make a rip cut without following all the setup steps in the previous procedure. • After the saw has been set up, insert the yellow key, and turn the saw on with the switch on the arm. Let the blade build up to full speed. • Stand at the infeed side of the blade and out of the INFEEDFOR OUT RIP CUTTING BLADE line of the workpiece, in case kickback occurs. ,_ • WARNING: Never stand directly in the line of cut.
