  • 6x Always keep the muzzle of your carbine pointed in a safedirection.

    Never point any firearm at anything you do not intend to shoot. Beextremely alert and aware of all persons and property within therange of your ammunition.

    x Never rely totally on your firearms mechanical safetydevices.

    Always assume that your carbine can be fired at any time, even withall safety mechanisms engaged.

    The fire selector is the only apparent external safety device of thePS90 Carbine : when this fire selector is at the position S (safe), it isimpossible to operate the trigger.

    The PS90 has also several passive safety mechanisms that enhancesafety.

    As with other carbines, you must always treat your PS90 asready-to-fire, and only load a round and cock the carbine whenshooting is imminent.

    Like any mechanical device, a safety can sometimes fail; it can bejarred or inadvertently manipulated into an unsafe condition.

    Mechanical safeties merely aid safe gun handling and are noexcuse for pointing your carbines muzzle in an unsafe direction.

    Safe gun handling does not stop with your carbines mechanicalsafety devices : it starts there. Always treat this carbine with therespect due to a loaded, ready-to-fire carbine.

    Read and understand the cautions and properhandling procedures outlined in this booklet before

    using your new firearm.

    1. SAFETY INFORMATION

    As a carbine owner, you accept a set of demandingresponsibilities. How seriously you take these responsibilities canmean the difference between life and death.

    There is no excuse for careless or abusive handling of anyfirearm. At all times, handle your PS90 and any other firearm withintense respect for its power and potential danger.

  • 7x Avoid carrying your PS90 with a round in the chamber.

    For good safety practice, it is recommended that a round is notchambered until immediately before you will fire the carbine.

    If it is nevertheless necessary to carry the PS90 with a round in thechamber, set the fire selector at the position S (safe).

    For law enforcement personnel, refer to the procedures of yourdepartment on carrying a loaded carbine with a round in thechamber.

    x Whenever you handle your PS90, or hand it to someone,make sure it is completely unloaded.

    To fully unload your PS90, proceed as described in 4.5.

    It is vital that, when unloading, you remove the magazine from yourcarbine so that a round is not automatically chambered whenreleasing the cocking handle.

    Always keep the chamber empty unless shooting is imminent.

    x Do not transport your carbine loaded.

    Keep it unloaded, whether carried on a sling, in a gun carrying bag oranother kind of container.

    For law enforcement personnel, refer to the procedures of yourdepartment on carrying a loaded carbine.

    x Beware of barrel obstructions.

    When preparing to shoot your carbine, check for a barrel obstructionas follows : first fully unload the carbine as described in 4.5.

    Be certain no live round is in the chamber !

    Then glance down the barrel to be sure it is clear of any obstruction. Ittakes only a small obstruction to dangerously increase pressures.Before the first firing, clean the bore with a cleaning rod and rag, andwipe away any anti-rust compounds in the chamber and around thebreech block.

    x Be alert to the signs of ammunition malfunction.

    If you detect an off sound or light recoil when a round is fired, fullyunload the carbine as described in 4.5.

    With the cocking handle pulled and held rearwards and the chamberempty, glance down the barrel to make sure that an obstruction doesnot remain in the barrel.

    If there is an obstruction, completely clear the barrel before loadingand firing again.

    Failure to follow these instructions can cause extensive damage toyour carbine and possible serious injury to yourself and others.
