Upper Blade Guide Assembly

1.Disconnect machine from power source.

2.Loosen lock knob (see B, Figure 14) and raise or lower upper blade guide assembly by turning the handwheel (C, Figure 14).

3.Position the blade guide assembly about 3/16” above the material to be cut. The scale (J, Figure 14) shows the distance from bottom of upper blade guides to the table surface.

4.Tighten lock knob (B, Figure 14).

Upper Blade Guides and Upper

Support Bearing

To adjust the bearing guides for proper blade control, proceed as follows.

1.Disconnect machine from power source.

2.Blade must already be tensioned and tracking properly.

3.Loosen the locking handle (A, Figure 17).

4.Adjust the guide bracket (B, Figure 17) by rotating knob (G, Figure 17) until the front of the guide bearings (C, Figure 17) are just behind the blade’s gullet (curved area at the base of the tooth). See Figure 18.

5.Tighten the locking handle (A, Figure 17).

6.Loosen set screw (D, Figure 17) on the guide bearing assembly, with a 3mm hex wrench. (Figure 17 shows the set screw for the right hand bearing; the set screw for the left hand bearing is shown in Figure 19.)

7.The guide bearing rotates on an eccentric shaft. Adjust the guide bearing, by rotating the knob (H, Figure 19) until the guide bearing rests lightly against the blade. Do not force the guide bearing against the side of the blade.

8.Tighten set screw (D, Figure 17).

9.Repeat the process for the other guide bearing. After adjustment, make sure the set screw (D, Figure 19) is tightened.

10.Loosen nut (E, Figure 19).

11.Adjust the support bearing using the knob (F, Figure 19) 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.
