How do I remove clutch drum on Mac335 petrol chainsaw?

The clutch is spun onto the cranck, it is a left hand thread, so undo CLOCKWISE there is a special tool pt no. 530031112, this has two pins on it and a 19mm nut so as to attach a socket and jar off against compression, do not try to lock the engine with piston stops or bits of cord in the spark plug hole, this only ends in disaster, if you have an impact gun this will take the clutch off in seconds ( do not turn the wrong way ) the tool is available from any Husqvarna or Jonsered dealer, do not be tempted to remove it by using a hammer and drift, the clutch legs are sintered and will snap off quite readily.
