2.Loosen the two screws (A) Fig. 25, and move the guides (B) as close as possible to the sides of the blade, being careful not to pinch the blade between the guides. Then tighten the two screws (A).
3.The front edge of the guide blocks (B) Fig. 25, should be adjusted so they are just behind the “gullets” of the blade teeth by loosening screw (C) Fig. 26, and moving shaft (D) in or out as desired. Then tighten screw (C).
4.The lower blade support bearing (E) Fig. 25, should be adjusted to support the rear of the blade during the cutting operation and also prevent the blade from being pushed too far to the back which could damage the set in the blade teeth. The support bearing (E) Fig. 25, should be set about 1/64" behind the blade by loosening screw (F) Fig. 26, and moving shaft (G) in or out. Then tighten screw (F).
5.The lower blade support bearing (E) Fig. 25, should also be adjusted so the back edge of the blade overlaps the outside diameter of the ball bearing by approximately 1/8 ". The bearing shaft (G) Fig. 26, is on an eccentric and to change position, loosen screw (F) and rotate shaft (G) until correct adjustment is made. Then tighten screw (F).
