I had the same problem last week.
The only way I could get mine free was to do the following:
1. Support the mast diagonally with the base of the mast on the floor and
roughly the middle of the top section top supported on a firm object that is
about 1m (3 feet) from the ground.
2. Then press down in the centre of the mast and flex it intermittently
and vigorously. Also rotate the mast from time to time.You should start to
see the two parts separating gradually.
3. Once they have started to separate, you should be able to remove the
sections in the normal way, however if not then try connecting to booms
earth side of the connection and twist in separate directions.
I have seen some people whack their mast with a mast extension, with
the idea that it crushes the sand granules. However I would not attempt that
as it's more than likely to damage the mast permanently.
Bye for now.........Colin
