Reducing the length of a Marzocchi All Mountain LS

If you know, please post the procedure for reducing the fork
length/travel for a Marzocchi All Mountain SL.

Thanks!

Zocchi are usually very good with manuals on their site - if its
possible im sure they'll have it on there?

for completeness, from the manual online...:

Before using to the TAS cartridge adjustment,
you will have to completely deflate the positive
air chamber located on the right leg, and then
re-establish the correct working pressure.
· By turning the knob located at the bottom of the
fork's leg clockwise, you will reduce the
maximum travel and the fork's length.
· By turning the knob located at the bottom of the
fork's leg counterclockwise, you will increase the
maximum travel and the fork's length.
WARNING!
Never force the knob past its limit, as the fork
could be damaged, resulting in an accident,
personal injury or death.
