Adjusting the Pitch
l
Pedal balance spring mechanism
Your Yamaha timpani is equipped with a unique pedal
balance spring mechanism (a coil spring counteract-
ing the tension of the head) which allows you to freely
change the pitch (note) of the instrument. When the ped-
al is moved, the pitch of the head will change, and the
balance spring ensures that the pedal angle (pitch) will
not change when you remove your foot from the pedal.

Caution
Never place your fingers or foot into the mov-
ing parts or the space under the pedal or base.
Serious injury can result if fingers or feet be-
come pinched.
Note
Do not loosen the spring tension adjustment
bolt by more than 3 rotations at a time, as
the toe of the pedal tends to drop abruptly
after a specific point.
