Adjusting Blade Guide
Bearings
The blade guide bearings can be adjusted left-
to-right, as well as front-to-back, relative to the
blade. Properly adjusted blade guide bearings
provide side-to-side support, from just behind the
gullets to the back of the blade, to help keep the
blade straight while cutting.
There are blade guide bearings on the upper and
lower blade guide assemblies. Both adjust in a
similar manner.
IMPORTANT: Make sure the blade is tracking
and tensioned correctly before performing this
procedure (see Tensioning Blade on Page 27).

Note:
The guide bearings should be
positioned behind the gullets a distance equal
to that of the support bearing behind the
blade (see Page 29).

Note: With wider blades, it may not be
possible to bring the guide bearings just
behind the blade gullets. Position them as
far forward as possible without allowing the
guide bearing housing to touch the back of
the blade.

Blade teeth are angled out slightly, protruding
wider than the blade thickness; this is known
as blade "tooth set" (see Figure 39). If angled
out parts of the teeth contact guide bearings
during operation, they will get bent inward,
ruining the tooth set. Therefore, the support
bearing must be set to prevent teeth from
contacting guide bearings during operation
(refer to Page 29 for details).
