okay i'm going to quickly go through
this this is how to unlock your arm on
the miter saw for dewatt
miter saw dws-779
i'm sure they've all worked the same but
it took me a while to figure this out
and i couldn't find any instruction
videos online
and the instruction manual didn't really
tell you how to do this so i'm going to
do it quickly you have a locking pin
it's for this model it's located right
there
and when you push down on this arm you
want to pull out on the locking pin it's
that simple
it took me a little bit but that's how
you do it
