1.Loosen depth rod locking knob (A) Fig. 10, and depth indicator knob (D) Fig. 10, allowing the depth rod (E) Fig. 10 to contact one of the turret stops (B) Fig. 10. Normally the deepest desired cut is set with the depth rod resting on the shortest turret stop (A) Fig. 11. The other two fixed stops (B) Fig. 11 provide reduced cutting depths of 1/4" and 1/2" respectively. The three adjustable stops (C) Fig. 11 may be adjusted to any desired height. Any combination of fixed and/or adjustable stops may be utilized to achieve the desired depths required for a particular job.
