Place the shaft under your right  arm, with the  club head face  down in your left hand, use your right  hand to turn  the locking lever 2 turns. Rock  the club head back and forth until the desired club number is between the i mode on the shank and the HOME line on the back of the head. (Choose i for irons, w for wedges or the p for the putters). These are the 3 modes (i =1-9)    (w =1-5)    (p =1-4)

Changing the locking lev er  position
Turn the locking lever 6 turns.  Set the shank socket in a  different position on the hex coupling nut. (Hold the coupling nut from turning (with your thumb) and rotate the shank. Turn the lever back to lock. The lever should be vertical with the shaft, if not,  move the shank socket to another position  on  the coupling nut. Once you understand this,  it  only  takes  a  few  seconds to change the locking lever to an upright position. This adjustment is needed because of initial wear of the threads and teeth.  After breaking in you  will not have to do this again.  To maintain the lever in the same  position after taking it apart,  line up the mode P (putter)  with the same number on the end  of  the coupler.This will  hide  the lever at address.

Telescopic Shaft
To extend and lock shaft, hold the grip end in your right hand and the head in your left  hand  and  snap  open firmly.  To shorten for travel,  hold shaft near the head and tap  grip  end  firmly on  a  hard surface (concrete, rock etc.). Place the shaft on  the  adjustable golf  club  shank taper  to  lock.
