Lower Blade Guides and Lower
Support Bearing
1. Disconnect machine from power source.
2. Blade must already be tensioned and tracking
properly.
3. Loosen two hex cap screws (J, Figure 20).
4. Adjust the guide bracket (K, Figure 20) so that
the front of the guide wheels are just behind
the blade’s gullet (curved area at the base of
the tooth).
5. Tighten the two hex cap screws (J, Figure 20).
6. Loosen lock ring (L, Figure 20) on the guide
wheel assembly.
7. Rotate the knob (M, Figure 20) until the guide
wheel rests lightly against the blade. Do not
force the guide wheel against the side of the
blade.
8. Tighten the lock ring (L, Figure 20).
9. Repeat this adjustment for the guide wheel on
the opposite side.
10. Loosen thumb screw (N, Figure 20).
11. Slide the shaft of the support bearing until the
space between the support bearing and the
back edge of the blade is approximately 1/64”.
A convenient way to achieve this spacing is by
placing a dollar bill folded twice (four
thicknesses of a dollar bill is approximately
1/64”) between blade and support bearing.
12. Adjust the support bearing until it lightly
contacts the dollar bill.
13. The bearing holder on the shaft is eccentric.
Rotate the support bearing until the back edge
of the blade overlaps the front face of the
support bearing by approximately 1/8”. See
Figure 21.
14. When adjustments to the support bearing are
complete, tighten thumb screw (N, Figure 20).
