Simply lift the plug halfway to engage the sliding pin, and turn counter clockwise to unthread.  To replace, repeat turning clockwise.

We recommend applying a generous amount of plumber’s putty or non-oil based putty under the flange of the Lavatory Drain between the Flange and the upper surface of the sink.  As you tighten the nut from underneath the sink, the putty or silicone will form a seal, therefore eliminating the chances of a slow leak.  Immediately remove any excess putty of silicone with a damp cloth after installing and tightening.

Yes.  Simply remove and adjust the small Set Screw which is located at the end (bottom) of the Plug Stem.  Turn counter-clockwise to adjust upwards or clockwise to adjust downwards.  Then, tighten lock nut. When adjusted properly, the Plug will fully seal the tub in the “closed” position yet will lift up high enough to allow the water to drain from the tub in the “open” position.

You can cut the pipe.  You must cut using a pipe cutter, do not cut the flange side.  Then smooth the edges with emery cloth.
