Guide Bearings Table Tilt

The guide bearings ensure that the blade cannot twist during operation. Perform the steps below for both upper and lower guide bearings.

To adjust the guide bearings:

1.Carefully tighten the guide adjustment knobs until the guide bearings just touch the blade on each side as in Figure 17. Do not deflect the blade while making this adjustment and do not over-tighten!

2.Tighten each of the jam nuts.

Ideally, the guide bearings should have 1 or 2 thousandths (0.001-2") clearance from the blade and should not pinch the blade. The blade could become hot and deformed if excessive pressure is applied by the guide bearings. The system employed by this bearing assembly will give clearance for the blade when the jam nuts are tightened. Make sure the jam nuts are tight before starting the machine.
