Precautions for Tightening Bolts
Use a torque wrench to tighten bolts to specifications. After
tightening bolts to specification, mark the tightened bolt
head to ensure that all the bolts have been tightened.
Be sure to use Hitachi original bolts. If the bolt length is
too long or short, the bolt will not be tightened correctly,
possibly inducing an accident
