IMPORTANT: Do not "flop" (reverse) the reed pet-
als for additional use – replace reed when neces-
sary.
Reed should lie flat. There should be no pre-load
(pressure between reed and reed-block), although a
slight pre-load is tolerable.
The maximum allowable opening between reed and
reed-block is .020 in. (0.5mm). This must be checked
with a flat blade feeler gauge, as shown.
