CAUTION:The hinge pin and the locking areas are very important mating surfaces. The receiver, the
barrels and the fore-end iron are subject to very high loads.  Improper lubrication of these components can
cause seizing of parts or malfunctioning of the shotgun. (The areas to lubricate are indicated by the arrows
on Fig. 8). Before using the  shotgun, make sure that lubricant is present as instructed.

NOTICE: Once the shotgun is handled, always
and accurately clean all external surfaces (wood
and metal) with a soft and clean patch in order
to preserve the delicate finishes over time.  The
Beretta Cleaning Cloth (FAW08), available at
fine gun dealers, is specially designed to clean
your fine shotgun.  Poor handling and cleaning
of the firearm could compromise your Beretta
warranty.

At various points in this manual you will be instructed to visually check the cartridge chambers of the
Beretta SO10 shotgun to be certain this is unloaded.  This should soon become second nature to you, as

•Never assume that a firearm is unloaded. 
•Never point or push a firearm toward yourself or another person.  
•Always visually check to see that the chambers are unloaded. 
•Engage the safety and open the shotgun by pushing the top lever to the right before...

If the shotgun is unloaded, proceed to the following step, otherwise refer to the procedure: “UNLOADING
THE SHOTGUN”.
•Swing the barrels upwards to close the shotgun. When the top lever has fully moved to its centered
position, the barrels are correctly closed in the receiver.

DRY FIRING/SNAP CAPS
Dry firing is defined as firing a firearm with no
cartridges in the chambers. The snap caps
supplied with the Beretta SO10 shotgun are inert
chamber inserts that allow the gun to be dry-fired
without damaging the firing pins. 
•Open the gun.  
•Insert snap caps into the chambers (Fig. 16).
•Pull the trigger to decock the first hammer.
•Push the selector to the second position.  (On
some models this is not possible since the
selector is blocked by a screw.)
NOTICE:If the...

Visually check the barrels to be sure there are no obstructions in the chambers and bores (the inside of the
barrels). This is extremely important because if a cartridge is fired into an obstructed barrel, a catostrophic
failure can result.

“CHECK THE GUN IS UNLOADED” paragraph. 
•Push the top lever to the right and rotate the barrels downwards to open the shotgun.
