Loosen the table lock knob and rotate the angle adjustment knob to tilt the saw table up or down to align table 90° to blade (0° position). Using a hex key, adjust the zero stop set screw until the set screw just touches the saw housing. Check squareness of the saw table to the blade.

Remove the switch key. Check the position of the blade on the lower tire. The blade should be completely on the tire. If not, adjust the tracking until the blade is on both tires. Rotate the upper wheel by hand in a clockwise direction for a few more turns. Make sure the blade stays in the same location on the tires. Readjust, if necessary, until blade is tracking properly. (3 mm) blade may not track properly in the center of the wheel. It may be better to track this blade on the back half of the upper wheel. WARNING: Failure to turn the saw off, remove the switch key, and unplug the saw could result in accidental starting causing possible serious personal injury. Before using the band saw, turn the blade tension knob on the top of the saw clockwise to engage tension. NOTE: Adjustments of blade tension can be made at anytime. Another method of checking blade tension has to do with the sound the blade makes when plucked like a guitar string. Pluck the back straight edge on the coasting side opposite the blade guides while turning the tension knob. Sound becomes higher pitched as tension increases. Using either method to check blade tension can be developed with practice. [. . . ] Kink in blade caused by cutting too small radius or turning the material too fast when cutting. Thrust bearings scarred or not rotating. Blade guides and bearings are in contact with the blade. 1. See Adjustments section, Adjusting Blade Tension. [. . . ]
