Adjusting Blade Guides - Grizzly G0640X Owner's Manual

Adjusting Blade
Guides
The blade guides provide side-to-side support to
help keep the blade straight while cutting. The
blade guides are designed to be adjusted in two
ways—forward/backward and side-to-side.
To adjust the upper and lower blade guides:
1. Make sure the blade is tracking properly and
that it is correctly tensioned.
2.

3. Familiarize yourself with the upper blade
guide controls shown in Figure 22.

Loosen the cap screw on the lateral adjust-
ment rod and adjust the blade guides until
the edges of the bearings are
blade gullets, as illustrated in Figure 23.
Note: The
/ " spacing is ideal, although with

larger blades it may not be possible. In such
cases, adjust the guide bearings as far for-
ward as possible to the blade gullets, and still
maintain the proper support bearing spacing
adjustment.

NOTICE
Make sure that the blade teeth will not con-
tact the guide bearings when the blade is
against the rear support bearing during the
cut or the blade teeth will be ruined.
5. Tighten the cap screw on the lateral adjust-
ment rod.
6.
Loosen the bearing rotation adjustment cap
screws.
7.
Use the knurled knob to rotate the bearings
0.004" away from the blade.
Note: 0.004" is approximately the thickness
of a dollar bill.
8. Tighten the cap screw to lock the blade guide
bearings in position.
9.
Repeat this procedure for the lower guides.
(All though the lower guides are set up a little
differently, the concept is the same.)
NOTICE
Whenever changing a blade or adjusting ten-
sion and tracking, the upper and lower blade
support bearings and guide bearings must
be properly adjusted before cutting opera-
tions.
