HOW TO ADJUST MODERN REK-O-KUT ARM CUEING HEIGHT

The arms normally are shipped with a set of metric hex wrenches with which to adjust all of their features.

Adjustment for cueing is basically to raise or lower the cylinder that provides this action.  Use the appropriate wrench to loosen the single set screw.  It will normally require only a small movement.  Once in place, re-tighten it.  Check that with the lever up, that the stylus sufficiently clears the record.  This should normally be more that 1/4 inch.
