(3.) ADJUSTMENT FOR UNEVEN ANGLE OF BED: If 90 sample bend is true at both ends but less
than 90 at center of piece, loosen Apron Mounting Bolts (figure 1) and lover the Apron approximately 1/32" by unscrewing
the Apron Adjusting Screws. Retighten the Apron Mounting Bolts and tighten Truss Nut (C, figure 3) until both Jaws of
brake are flush at brake center (see figure 2).
4. The jaw opening has been set at the factory for approximately 2". If Item 27 Counterbalance Springs take a slight
set, this opening can be re-adjusted by turning Item 76 Adjusting Screws as required.
MAJOR BRAKE ALIGNMENT:
Follow the procedure listed below if brake is badly out of alignment. (If your brake does not have all the Truss Nuts
referred to in these instructions, disregard those steps.)
(1.) Loosen all Truss Nuts (A,B,C,D,E, figure 3) and Truss Rod Turnbuckle until all tension is released.
(2.) Tighten the Truss Rod Turnbuckle until the rods are snug at tension point (R).Tighten an additional 1/4 turn.
(3.) Tighten Truss Nut (B) until snug. Tighten an additional three complete turns.
(4.) Check Apron at the alignment points (X, figure 1) to see if it is flush with top of Lower Beam Jaw (see inset, figure
1). Up and down movement of the Apron is controlled by turning the Apron Adjusting Screw (figure 1) at each end of the
Apron.
(5.) Tighten Truss Nut (C, figure 3) until Apron is flush with Lover Beam Jaw alignment point (Y, figure 1).
(6.) Tighten Truss Nut (E, figure 3) as tight as possible.
(7.) Tighten Truss Nut (A) until the Upper Beam Jaw is straight and parallel in relation to the Lover Beam Jaw.
(8.) Tighten Truss Nut (D) until the center of the Upper Beam Jav bows forward slightly.
