To Adjust Blade Guides:

The blade guides help keep the blade from twisting and binding. The blade will be ruined if the blade teeth hit the blade guides while using the band saw. The set of teeth and the sharpened edge of teeth will be damaged by hitting the blade guides. Proper adjustment of the upper and lower blade guides will prevent this from happening.

■Remove the blade guard by loosening the two screws set with the 4 mm hex key.

■Loosen the two blade guide support screws that lock the upper blade guides. Slide the two guides to within 1/32 in. (0.8 mm) of the blade. Do not pinch the blade. Make sure one guide is not further away from the blade than the other. Retighten the two blade guide support screws securely.

■Replace the blade guard if no additional adjustments are to be made.

■Repeat this procedure on the lower blade guides located under the saw table. See Figure 14.
