With the blade on and properly tensioned, hold a straightedge close to the center of both wheels. Make sure the straightedge fully extends across the wheels as shown in Figure 46. Figure 46.Checking wheel alignment with a straightedge. —If the wheels are coplanar, the straightedge wil touch the top and bottom of the outside rims on each wheel. —If your wheels are not coplanar, place the straightedge on the lower wheel first— ensuring that it touches both the top and bottom rim—and adjust the tracking knob to see how the upper wheel lines up with the straightedge. NOTICE If the table is shifted, the fence will be affected since it is attached. NOTICE Lead adjustments will change when new blades are mounted on the saw. -41 G0555X 14" Extreme Series Bandsaw —If the straightedge will not touch the top and bottom rim of the upper wheel evenly, determine which wheel sticks out farther. The wheel that does NOT stick out the farthest is the wheel that needs to be shimmed. Shimming a wheel 1. Adjust the tracking knob so the top wheel is parallel with the bottom wheel. With the straightedge touching both points of the wheel that does not need to be adjusted, measure the distance away from the incorrect wheel with a fine ruler (see Figure 47). The distance measured with the ruler is the distance the wheel must be corrected. Figure 47. Measuring wheel difference. 2. Remove the blade from the saw, then remove the wheel that needs to be shimmed. 3. Shim washers work well because they are available in a wide range of thicknesses. Measure how many you need and place them on the mounting shaft. 4. Replace the wheel, any remaining washers, and the securing nut. Tighten the blade as it will be used during operation before you check the wheels. Often the wheels may be coplanar with the blade loose, then be pulled out of alignment when it is tightened. 5. The first time you get the wheels coplanar, place a mark on each wheel where you held the straightedge. This assures repeated accuracy every time you adjust your wheels. When wheels are properly coplanar, the blade may not be centered on the crown of the wheel, but it will be balanced. See Figure 48 to better understand coplanarity. Figure 48. Coplanar diagram. -42 G0555X 14" Extreme Series Bandsaw Blade Tensioner Over the life of the machine, the blade tensioner system may need to be reset for correct operation. To reset the blade tensioner: 1. DISCONNECT BANDSAW FROM POWER! 2. Release the tension lever shown in Figure 49 and remove the bandsaw blade. Figure 49.Blade tension controls/components. Tension Lever Tensioning Knob Tension Lever Crossbar 3. Place the new blade onto the wheels and between the blade guide bearings. Note: A new blade is used to calibrate the tensioner because it is unstretched. 4. Loosen the setscrews in both of the spacers indicated in Figure 50. 5. Back the spacers away from the tension lever crossbar shown in Figure 49. Figure 50. Loosening the spacer set screws. Upper Spacer Lower Spacer Sliding Bracket 6. Pull the tension lever down to the horizontal position. 7. Pull up on the tensioning knob (Figure 49) until the blade touches the wheel. 8. Thread the upper spacer down until it touches the top of the tension lever crossbar. 9. Tighten the setscrew on the upper spacer. 10. Tension the blade (refer to Page 19). 11. Thread the lower spacer down until it touches the top of the sliding bracket indicated in Figure 50. 12. Move the lower spacer back up the shaft about 1-2 turns to leave a small space, and tighten the setscrew (Figure 50). 13. Make sure there is no tension on the blade when the lever is released. If all the tension is not released, the lower spacer needs to be threaded farther down the shaft toward the sliding bracket. -43 G0555X 14" Extreme Series Bandsaw 110V Wiring Diagram (Prewired) ............... ....................................... -44-G0555X 14" Extreme Series Bandsaw .......................................................................................................................................................................................... 220V Wiring Diagram ............... .......................................
