6.Loosen both cap screws behind the guide bearings, then rotate the adjustment cap screws so the bearings evenly and lightly touch the sides of the blade (see the illustra- tion in the following figure).
Note: When the blade guide bearings are properly adjusted against the blade, they should still be able to rotate.

7.While keeping the adjustment cap screws from turning with one hex wrench, re-tighten the locking cap screws to secure the set- tings.
Whenever changing a blade or adjusting the blade tension or tracking, the support and guide bearings must be
