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).
