Adjusting the Blade Guides
Upper Guides:
To adjust the upper blade guides, fi rst position the roller guides relative to
the blade by slackening off the hex nut (A--Fig.9) and moving the guide
carrier until the roller guides are approx. 1/16" behind the gullets of the
blade. Next set the roller guides to within 1/32" of the blade by releasing the
screw (B--Fig.9) on each side of the blade. Do not set the guides too close
as this will adversely affect the life of the blade. Finally, adjust the thrust
bearing to be just clear of the back of the blade by unlocking the
hex nut (C--Fig.9). When the correct adjustment is reached, lock the thrust
bearing in position with the hex nut (A--Fig.9).
