Blade.Guides
The roller discs keep the blade from wandering from side-
to-side. These discs support the blade just behind the
blade gullet to prevent the blade from tracking off center
when hard and soft areas are cut in the wood (see.Figure.
23).
The support bearings prevent blade twist by stopping the
blade from being pushed back during a cut.
The support bearings and discs reduce friction and
blade wear during a cut, but after the cut, the blade
must spring back to position and not touch the support
bearings.

Note: Make sure the blade is tensioned and tracks on the
center of both wheel tires before you adjust the blade-
