husqvarna 40 chainsaw hand break problems?

is there a diagram site for this model? So that I can check that everything thing is aligned properly in the housing, as currently I cannot get the metal brake belt to disengage enough for the unit to be put back properly -ie the safty handle dosnt negage or release
