YAMAHA ORIGINAL DESIGN VIBRATO SYSTEM RM - Pro II / III (part 1)
The strings are top-loaded from the rear of the bridge and it is not
necessary to cut off the ball end as on other vibrato systems.
Following is the procedure for changing strings and adjusting the
vibrato system:
1) Loosen the three hexagonal screws on the lock above the nut.

2) Loosen the individual string locks using the hexagonal wrench.

3) Replace the old strings with new strings and tune the guitar to
the correct pitch.
4) Using the supplied hexagonal wrench, lock each string.

After locking the strings, make sure that the fine tuning thumb
screws are in the middle of their range of travel.

5) Tune the guitar to the correct pitch.
6) Remove the back plate to gain access to the vibrato strings.
Three springs are factory installed and we recommend that
these springs be adjusted so that the vibrato bridge plate is
parallel to the top of the guitar when it is tuned to correct pitch.
7) Lock the strings above the nut using the supplied hexagonal
wrench. (illustration — A)
