CLEANING OF THE CHOKE TUBE AND ITS HOUSING
INSTALLATION OF THE CHOKE TUBE
WARNING: Check the firearm is unloaded (cartridge chamber empty, receiver
empty, magazine tube empty). Check that the firearm is unloaded by looking
through the ejection port, the loading gate and the chamber. If the shotgun is
not unloaded, unload it as described in the chapter “Unloading the firearm”.
Lower the hammer on the unloaded gun by pulling the trigger.
WARNING: Never look into the muzzle or change tube on a loaded gun, even
with safety engaged.
●
Carefully clean the choke housing. If necessary, use a cotton patch coated with
Beretta Gun Oil. Dry the choke housing using a soft patch.
●
Check the choke to make sure it is perfectly clean inside and outside.
●
Apply a thin coat of Beretta Gun Oil to the thread of the barrel and of the choke
tube.
WARNING: Check the firearm is unloaded (cartridge chamber empty, receiver
empty, magazine tube empty). Check that the firearm is unloaded by looking
through the ejection port, the loading gate and the chamber. If the shotgun is
not unloaded, unload it as described in the chapter “Unloading the firearm”.
Lower the hammer on the unloaded gun by pulling the trigger.
WARNING: Never look into the muzzle or change tube on a loaded gun, even
with safety engaged.
CAUTION: Check that the choke tube is in perfect condition (not damaged)
prior installing it.
●
Check the choke and the thread of the barrel to make sure they are perfectly clean
and lightly oiled.
●
Insert the desired choke into the choke housing.
●
Carefully hand screw the choke into the barrel clockwise. Using the Beretta
spanner, tighten the choke until it is fully bottomed into its recess in the barrel.
●
Remove the spanner after tightening.
WARNING: Periodically check, under safe conditions (cartridge chamber
empty, receiver empty, magazine tube empty and breech bolt in OPEN
position) whether the choke is fully and tightly set into the barrel. If necessary,
firmly tighten the choke, using the Beretta spanner, until it can be tighten no
more. This tightening is needed to avoid damage to the barrel and to avoid
propelling the choke out of the muzzle when the gun is fired, which may cause
damage to the gun or injury to persons.
