PREVENTIVE MECHANISM FOR
UNLOADED OPERATION
The machine employs a preventive
mechanism for unloaded operation.
The machine enters a state where the push
lever stopper runs into the upper part of the
push lever and the push lever cannot be
pushed up. This takes place when the
magazine is not loaded with nails or when
the remaining number of nails becomes less
than 6 (This differs by the type of nail).
Load the nails immediately if you come
across with such a condition during
operation.
