WARNING – LEAD EXPOSURE
The safety selector is held in each of its three positions by a plunger that is under
spring tension. Therefore, the gun user should frequently check the position of
the safety selector to be certain it has not been inadvertently moved. If the safety
does not function properly, or if the selector seems to move too easily, or if the
safety selector does not seem firmly positioned in any of its three positions, the
rifle should be discontinued from use and returned to the Newport Product
Service Department for repair (See p. 27).
