To calibrate the blade tilt: 1. Disconnect the saw from the power source! 2. Move the blade tilt to 90. according to the gauge, and raise the main blade as high as it will go. 3. Place a machinist's square on the table surface and between the blade teeth. Inspect for gaps between the blade and the square. 4. If a gap exists at either the top or bottom of the square, loosen the set screw in the 90. tilt stop nut shown in Figure 83. 90. Tilt Stop Nut 45. Tilt Stop Nut Leadscrew Nut Figure 83. Blade tilt stop nuts. 5. Turn the handwheel until the blade and square are flush from top to bottom. 6. Snug the 90. tilt stop nut against the leadscrew nut and tighten the set screw. 7. Recheck the blade with the square to ensure the nut has not been over-tightened. 8. Adjust the blade angle until you hit the 45. positive stop. Check the bevel with an adjustable square set to 45.. 9. If variations exist, loosen the set screw in the 45. tilt stop nut (Figure 83) and adjust the stop nut until the blade and square match. 10. Tighten the set screw and recheck the bevel by adjusting the blade back to 90., then back to 45.. 11. Check the scale for accuracy at 45. and 90.. —If the scale reads 45. when the blade is at 45. and 0. when the blade is at 90. to the table, it is accurate. —If the scale reading does not match the blade angle, perform the adjustments in Step 12. 12. Loosen the lock nut called out in Figure 84 and rotate the barrel nut until the scale matches the blade angle.

G0588/G0591 12" Sliding Table Saws -47 Squaring Crosscut Fence to Blade Squaring the crosscut fence to the blade ensures that cuts made with the crosscut fence will be square. This procedure can be done by using a piece of scrap plywood as a test piece and making five test cuts, then adjusting the fence as necessary. To square the crosscut fence with the blade: 1. Make sure the blade is parallel with the sliding table. 2. Prepare the scrap test piece by numbering all four sides as shown in Figure 85. Figure 85.Fence adjustment test piece. 3. Use the crosscut fence to cut 1.2" off of each side of the test piece, then cut side 1 again (make 5 cuts total). 4. Measure the test piece diagonally from corner- to-corner as shown in Figure 85. —If both measurements are not within 1.16", then the crosscut fence needs to be adjusted. Proceed to Step 6. — If both measurements are within 1.16" then you are finished with this procedure. 5. Loosen the hex nut shown in Figure 86 and rotate the hex bolt to square the crosscut fence.

G0588/G0591 12" Sliding Table Saws -49 Troubleshooting Symptom Possible Cause Possible Solution Motor will not start, or it growls on start up. 1. Emergency stop button is depressed. 2. Power supply fuse or circuit breaker has tripped. 3. Thermal overload has tripped. 4. Toggle switch is broken inside. 5. Start capacitor is at fault. 6. Motor fan cover is dented, stopping the fan from being able to spin. 7. Motor is at fault. 1. Rotate the button clockwise and allow it to pop out. 2. Disconnect power, and inspect circuit for electrical shorts and repair. Replace circuit breaker if it is old or has tripped many times. 3. Reset the thermal overload. 4. Disconnect power, and use an ohmmeter to check switch terminals for continuity, and replace switch if required. 5. Replace start capacitor. 6. Replace motor fan cover (and fan, if damaged). 7. Replace motor. Motor fails to develop full power (output of motor decreases rapidly with decrease in voltage at motor terminals). 1. Power line overloaded with lights, appliances, and other motors. 2. Undersized wires or circuits too long. 3. Blown capacitor. 1. Reduce load on power line. 2. Increase wire sizes or reduce length of the circuit. 3. Replace the capacitor. Motor overheats. 1. Motor overloaded. 2. Air circulation through the motor restricted. 1. Reduce load on motor. 2. Clean out motor to provide normal air circulation. Motor stalls (resulting in blown fuses or tripped circuit). 1. Short circuit in motor or loose connections. 2. Low voltage. 3. Incorrect fuses or circuit breakers in power line. 4. Motor overloaded. 1. Repair loose or shorted terminals, or worn insulation on motor. 2. Correct the low voltage conditions. 3. Install correct fuses or circuit breakers. 4....
