procedure.
<When using the MUT-II>
Gently tap the middle of the belt between the pulleys (the
place indicated by the arrow) with your finger as shown
in the illustration, and check that the vibration frequency
of the belt is within the standard value range.

the vibration frequency by using the MUT-II.
<When using a tension gauge>
Use a belt tension gauge to check that the belt tension
is within the standard value.
<Belt deflection check>
Apply 98 N of force to the middle of the drive belt between
the pulleys (at the place indicated by the arrow) and check
that the amount of deflection is within the standard value.
