IMPORTANT: Do not “flop” (reverse) the reed petels for
additional use – replace reed when necessary.
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 0.020 in. (0.5mm). This must be checked with a flat
blade feeler gauge, as shown.
0.020 MAX.
If the opening exceeds .020 in. (0.5 mm), or if the reed is
chipped, cracked or otherwise damaged, replace.

If reed block was disassembled, reassemble by locating
reeds (a) on pins with (c) retaining washer (b). Use new
tab-washer. Insert bolt (d), and torque to 60 lb. in. (6.5
N·m); then, if necessary, continue the torque to align flat on
hex-head to locking tab (e). DO NOT exceed 100 lb. in.
(11.5 N·m) of torque. Bend up lock tab to secure bolt posi-
tion.
