Inspect all blades for proper installation, orientation, tightness, sharpness, and overall
condition. Be sure the lift fins are oriented to the top of the blades. Verify that the mount
bolts are secure, the blades are sharp, and free of any nicks, cracks, or bends. Always
replace any damaged, dull, or missing blades before operating the Articulator. The Rec-
ommended torque value for the blade bolts is
75 ft/lbs .
