Your Yamaha timpani are equipped with a plastic head carefully mounted and adjusted at the
factory. However, new heads tend to stretch during shipping and storage, so it may be neces
-
sary to re-tune the instrument before using. Before playing the pedal timpani for the first time
after purchase, please follow the procedure below and make sure that the head is properly
adjusted.

The area between the bearing edge and the
inner circle of the counter hoop is called the
collar. Please make sure that the width of this
collar is uniform, as shown in the illustration
titled “Correct”.

in this position, realign the head and hoop as
shown in the “Correct” illustration.

Fully depress the heel end of the pedal. While
holding the pedal in this position, use the sup

It is very important that all tension rods be
turned the same amount.
Never place your fingers or feet into the
spaces underneath the pedal, the base
portion of the instrument, or between
moving parts such as the casters. Serious
