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.
