The free carrier option featured on several FABARM semi-automatic models allows the shotgun to be unloaded safely without chambering a shell from the magazine. This feature also allows for the shotgun to be stored or handled safely with shells in the magazine but with the chamber remaining empty.
To load when chamber is closed:

Make sure the safety is on! *Point firearm down range
Push the free carrier latch to the rear of the gun until it clicks.
Pull the bolt to the rear until it locks into place in the open position.
Load a shell into chamber and depress the bolt release button.
Turn the gun over and load additional shells into magazine.
You are now handling a loaded firearm!
With the free carrier feature, an unfired shell may be unloaded from the chamber by pulling back on the bolt cocking handle and ejecting the shell. Shells present in the magazine will not be loaded into the chamber during this process.

To load through magazine with the bolt closed:

Make sure the safety is on!
Load shell(s) into magazine by pushing the free carrier latch down with the shell and sliding the round(s) into the magazine.
Push the free carrier latch towards the rear of the gun until it clicks.
Pull the bolt to the rear and release it (depressing the bolt release button is not necessary).
At this point, additional shells may be inserted into the magazine
You are now handling a loaded firearm!
To completely unload the firearm:

Empty shell (if present) from the chamber
Visually inspect the magazine for additional rounds.
Depress the free carrier latch toward the rear of the gun to release shells from the magazine.
Cycle rounds out of gun by pulling the bolt to the rear of the gun
The gun is completely unloaded when the bolt locks back and the orange magazine follower is visible from the bottom of the gun.
