1.NOTE: Upper blade guard (B) Fig. 22, is shown removed for clarity.
2.Loosen the two screws (C) Fig. 22, and adjust the blade guides (D) as close as possible to the sides of the saw blade, being careful not to pinch the blade.Then tighten the two screws (C).
3.Loosen screw (E) Fig. 22, and move the guide bracket (F) in or out until the front edge of the guides (D) are just behind the “gullets” of the blade teeth. Then tighten screw (E).
4.The upper blade support/thrust bearing (G) Fig. 22, prevents the saw blade from being pushed back too far when cutting. The support bearing (G) should be adjusted approximately 1/32" behind the blade, so the back of the blade overlaps the outside diameter of the ball bearing by approximately 1/8". To adjust, proceed as follows:
