OPERATION OPERATION
6. Place blocks under both ends of the tracks to prevent the
machine from moving during transportation, and secure the
machine with chains or wire rope of suitable strength.
Be particularly careful to secure the machine in position so that
it does not slip to the side.
When securing the machine, put blocks between the wire rope
and the machine to prevent damage to the rope or machine.
