WARNING
Never install any type disc other than specified in Table 6-4 for the appropriate
cylinder. Installing the incorrect disc could result in violent rupture of the
cylinder and serious injury.
Make sure that multiple safety discs are not stuck together. Installing more
than one safety disc could result in violent rupture of the cylinder and serious
injury.
Never reinstall a used safety disc and/or washer. Once the retainer has been
removed or the valve has been rebuilt, the disc and washer must be replaced
with new components.
