3.Tighten lock knob. Make sure blade guide blocks (C, Figure 30) are still flat to the blade. If adjustment is necessary, loosen lock knob (A, Figure 30) and rotate assembly until guide blocks are flat to blade.

4.If movement of the blade guide assembly seems “stiff” when being raised or lowered, it can be adjusted to slide more easily. This is controlled by an internal spring and ball which provide varying degrees of resistance against the guide post. Use the set screw (D, Figure 30) to adjust the tension of this spring. To adjust tension on the spring, loosen knob (A, Figure 30), use a hex wrench to tighten or loosen set screw (D, Figure 30) until desired tension is reached, then re-tighten knob (A, Figure 30).
