x Avoid carrying your FN PS90
®
with a round in the chamber.
For good safety practice, it is recommended that a round is not
chambered until immediately before you will fire the carbine.
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).
For law enforcement personnel, refer to the procedures of your
department on carrying a loaded carbine with a round in the
chamber.
x Whenever you handle your FN PS90
®
, or hand it to someone,
make sure it is completely unloaded.
To fully unload your FN PS90
®
, proceed as described in § 4.5.
It is vital that, when unloading, you remove the magazine from your
carbine so that a round is not automatically chambered when
releasing 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 or
another kind of container.
For law enforcement personnel, refer to the procedures of your
department on carrying a loaded carbine.
x Beware of barrel obstructions.
When preparing to shoot your carbine, check for a barrel obstruction
as 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. It
takes only a small obstruction to dangerously increase pressures.
Before the first firing, clean the bore by using a cleaning rag holder
and clean rags (pieces of flannel), and wipe away any anti-rust
compounds in the chamber and around the breech block (also refer to
§ 6.1).
x Be alert to the signs of ammunition malfunction.
If you detect an off sound or light recoil when a round is fired, fully
unload the carbine as described in § 4.5.
With the cocking handle pulled and held rearward and the chamber
empty, glance down the barrel to make sure that an obstruction does
not remain in the barrel.
If there is an obstruction, completely clear the barrel before loading
and firing again.
Failure to follow these instructions can cause extensive damage to
your carbine and possible serious injury to yourself and others.
