• Heel moves up when releasing the foot from

the pedal after depressing the heel, or the heel

feels heavier than the toe.

→ Turn the spring tension adjustment bolt to

the left (counterclockwise).

the pedal after depressing the toe, or the toe

feels heavier than the heel

→ Turn the spring tension adjustment bolt to

the right (clockwise).

Use the supplied tuning key to turn the spring adjust-

ment bolt. Do not turn too many full rotations at once,

and re-check the adjustment every 2 turns by press-

ing the toe and heel of 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.

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.
