(6) CAUTION:
As these models are specifically designed to ensure that the armature is dynamically balanced, there
is extremely little allowable play or imbalance in comparison with other Hitachi electric power tools.
For this reason, be sure to handle the armature and its associated parts very carefully during
disassembly and reassembly.
