Lightly strike the head with the mallet about 2
inches (5 cm) from the bearing edge at each
tension rod. Check which tension rod has the
highest sound.
• Pitch of the highest sound is higher than
the tuning note (*)
g
Loosen the corresponding tension rod by
about 1/16 to 1/8 of a turn. First loosen
the bolt by twice the desired amount, and
then return (re-tighten) it by half. After
loosening the tension rod, repeat from the
beginning of step
3
.
• Pitch of the highest sound is lower than
the tuning note
g
Go to step
4
.

Tighten the other bolts little by little (by about
1/16 to 1/8 of a turn) until the sounds at the
corresponding striking points match the pitch of
the highest sound. Please note that tightening
one bolt also raises the pitch of the neighbor
-
ing and opposite tension rods. Thus, after tight
-
ening the tension rod with the lowest sound,
again check the pitch at the other tension rods
before tightening the tension rod with the next
lowest pitch. While alternately tightening the
other bolts, do not touch the tension rod with
the highest pitch (reference pitch).
5
Loosen all over-tightened bolts according to
the procedure described in step
3
(*)
. When
the pitch is approximately the same at each
bolt, repeatedly depress the toe and heel of the
pedal several times.

Repeat steps
3
through
5
until the pitch at
each bolt is exactly the same.

Check the sound by striking the head as de

scribed in step
2
.
• Sound is lower than the tuning note
g
Tune the instrument by tightening all ten
-
sion rods by an equal amount (max. 1/16
of a turn).
• Sound is higher than the tuning note
g
Tune the instrument by loosening all ten
-
sion rods by an equal amount (max. 1/16
of a turn) according to the procedure de
-
scribed in step

.

Operate the pedal as described in step
5
. If the
pitch does not change, the instrument is tuned
properly.
(If the pitch changes, repeat from step
7
.)
The instrument is now tuned to the lowest note
of its tonal range. Depress the toe of the pedal
to change to a higher note.

After tuning, perform
“Tuning Indicator Ad-
justment”
and then
“Pedal Adjustment”
