If it's a new boxed machine it will probably have transit bolts or brackets
internally which need to be undone/removed before running the machine.

The OP should look for the usually very obvious instructions on the box or
sellotaped to the machine (or inside the drum) on doing this before anything
else.

Always a good idea to thoroughly check the drum is both empty and revolves
freely before using.
