Vibrato System Locking Type - Yamaha ZV54660 Owner's Manual

When changing strings it is necessary to cut off the ball ends of
the strings.
Following is the procedure for changing strings and adjusting the
vibrato system:
1) Loosen the three clamp screws (A).
2) Turn the peg to loosen the string being replaced.
3) Loosen the lock screw (B) of the string being replaced.
4) Remove the old string.
5) Tighten the lock screw to lock the string in place, then roughly
tune the string. Do not over tighten the lock screw. Over tight-
ening may result in damage.
6) Make sure that the fine tuning screw (C) is in the middle of its
range of travel.
7) After tuning, rock the tremolo arm back and forth about three
times then re-tune the instrument.
8) If necessary, adjust the intonation and bridge angle.
9) Tighten the three clamp screws (A) to lock the strings at the nut.
10) Use the fine-tuning screws (C) to precisely tune the instrument
to the correct pitch.
