Using the supplied timpani key, tighten the tun-
ing bolts by 1/4 of a turn (90
°) in the order
shown below. It is very important to always
turn all tuning bolts by the same amount.
9
Tighten each tuning bolt by 1/8 of a turn (45
°) in
the order shown in step
5
.
10
● Toe and heel feel equal
→ Go to step
11
● Heel still feels heavier than toe
→ Repeat steps
8
through
10
● Heel feels lighter than toe
→ Head is tightened too much. Loosen the
head as described in step
7
.
11
Move the pedal into an intermediate position, as
shown in Fig. D, and remove your foot from the
pedal. Confirm that the pedal stays in this posi-
tion and does not move.
If the pedal stops in this position, adjust-
ment is complete. Return the pedal to the
position shown in Fig. C.
● If the toe of the pedal moves downward
→ Repeat steps
8
through
10
.
● If the heel of the pedal moves downward
→ Head is tightened too much. Loosen the
head as described in step
7
.

Strike the head lightly with the supplied mallet
etc. The standard striking point is shown below.

Take your foot off the pedal.
● Heel still moves up
→ Repeat steps
4
through

Put your foot on the pedal and fully depress it in
either direction (toe and heel).

.
● Heel feels lighter than toe
→ Head is tightened too much. Loosen the
head. Keeping the heel of the pedal de-
pressed, loosen the first tuning bolt by 1/
2 turn and then retighten it by 1/4 of a
turn. Perform this operation for all other
tuning bolts in the order shown in step
5
.
If necessary, repeat this procedure, until
proper tension is obtained.

Fully depress the heel of the pedal as shown in
Fig. C.
As the head will stretch over time, readjustment should be performed periodi-
cally (starting with step
7
)
For note comparison a piano is most suitable.
When the toe of the pedal is depressed, a higher
pitch is obtained.
For details on precise tuning refer to “Adjusting
The Sound Of Your Timpani” on the following
page.
The standard striking
point lies at distance
B from the kettle
edge, which
corresponds to 1/4 to
1/3 of distance A
(distance between
kettle edge and
center of head).
