Auxiliary Brake
Main caster Pedal caster
Playing the instrument without the main and
auxiliary brakes engaged can result in the in-
strument moving about during the performance.
It can also be a source of noise. Adjusting the
pedal, tuning, and adjusting the PAC system
can also be very dangerous if done without the
brakes engaged. The instrument unexpectedly
moving or falling over can lead to injury.
Stop using the instrument immediately if you
notice any abnormality in the auxiliary brake.
Also, release the main and auxiliary brakes be-
fore moving the instrument.

PAC Handling Precautions
l
Even with the PAC system adjusted to its
heaviest setting, the pedal is not “locked”
in place so do not use a heavy setting to
prevent the pedal from jumping when re-
moving the head.
l
There is a limit to how far the PAC adjust-
ment knob can be turned clockwise. Do not
force the knob if it becomes difficult to turn.
Doing so may damage the mechanism.

Never place your fingers or feet into the
spaces underneath the pedal, the base por-
tion of the instrument, or between moving
parts such as the casters. Serious injury can
result if fingers or feet become pinched.
Do not loosen the spring tension adjust-
ment bolt by more than 3 rotations at a
time, as the toe of the pedal tends to drop
abruptly after a specific point.

Interval for head replacement
When the head is slightly tensioned and
its surface looks wavy or shows dents, it is
time to replace the head with a new one.
The maximum head life normally is ap-
proximately 2 years and depends on the
frequencyandduration ofuse. However,
the head should always be replaced before
thesoundqualitydeterioratesdramatically.
If a head is left on and used more than two
years, the following problems may occur:
• Itmaybecomedifficulttotunethehead
to the proper pitch range.
• It maybecomedifficult to balancethe
pedal.
• The main unit mechanisms themselves
may become damaged.
Yamaha recommends replacing the head
every year.

BlockofWood,etc.
Never touch the pedal assembly when
looseningthe tension rods(when loos-
eningthe head).Also, never placeyour
fingers or feet in the space under the
pedal, around the base, or the moving
parts. Spring tension may cause the
pedal to suddenly move posing a great
danger.
