Inspect for the presence of the
safety pin. A missing pin is a
MAJOR defect.
If you cannot
remove the safety pin by hand,
there is a MAJOR defect.
If the cord is missing from either the
safety pin or the cotter key, classify
the defect MINOR.
Inspect the threads on the coupling
base. If the coupling base cannot
be properly assembled to the firing
device, there is a MAJOR defect.
