Turn the mounting nut manually,
and tighten it securely.
Important
● Do not use a tool to tighten up the
mounting nut. (Doing so may damage
the mounting nut.)
● Do not turn the main unit to tighten up
the mounting nut. (Doing so will apply
a powerful force to the thread, possibly
damaging the main unit.)
Upon completion of installation, check that the main unit does not easily rotate
and that there is no play.
