1. SAFETY INFORMATION As a carbine owner, you accept a set of demanding responsibilities. How seriously you take these responsibilities can mean the difference between life and death. There is no excuse for careless or abusive handling of any firearm. At all times, handle your FN PS90® and any other firearm with intense respect for its power and potential danger. x Always keep the muzzle of your carbine pointed in a safe direction. Never point any firearm at anything you do not intend to shoot.
x Avoid carrying your FN PS90® with a round in the chamber. x Beware of barrel obstructions. For good safety practice, it is recommended that a round is not chambered until immediately before you will fire the carbine. When preparing to shoot your carbine, check for a barrel obstruction as follows : first fully unload the carbine as described in § 4.5. If it is nevertheless necessary to carry the FN PS90® with a round in the chamber, set the fire selector at the position ‘S’ (safe).
x Be certain your carbine is completely unloaded before cleaning. Because so many gun accidents occur when a firearm is being cleaned, special and extreme care should be taken to be sure your carbine is unloaded before disassembly, cleaning and reassembly. Keep ammunition away from the cleaning location. Never test the mechanical function of any firearm with live ammunition. x Always completely unload your carbine when not in use. Your responsibilities do not end when your firearm is unattended.
x Treat every carbine with the respect due to a loaded gun, even though you are certain the gun is unloaded ! x Keep your fingers away from the trigger while unloading, loading and removing the magazine. Only touch the trigger when you are ready to shoot. x Be sure of your target and backstop. Take additional care during low light periods. Know the range of your ammunition. Never shoot at water or hard objects. x If your FN PS90® fails to fire, keep the muzzle pointed in a safe direction.
x Be defensive and on guard against unsafe gun handling around you and others. Don’t be timid when it comes to gun safety. If you observe other shooters violating any of these safety precautions, politely suggest safer handling practices. x Supervise and teach firearms safety to all members of your family. This is especially important when children and non-shooters are involved. Closely supervise newcomers to the shooting sports. Encourage enrollment in shooting safety courses.
Read and heed all warnings in this owner’s manual, on ammunition boxes and with all accessories that you install on your firearm. It is your responsibility to secure the most up-todate information on the safe handling procedures for your FN HERSTAL carbine. FN HERSTAL / FN AMERICA assumes no liability for incidents which occur when unsafe or improper gun accessories or ammunition combinations are used.
