Installing The Choke Tube

■ WARNING: Check that the shotgun is unloaded (empty cartridge chamber and carrier). If it is loaded, unload following the procedure described in the related section.

! WARNING: Never look directly through the barrel from the muzzle and do not ! replace the choke with the shotgun loaded even with the safety engaged.

CAUTION: Check that the choke tube is in perfect condition (not damaged) prior installing it.

• Apply a thin film of Beretta Gun Oil on the barrel thread and choke tube.

• Install the desired choke tube after checking it is perfectly clean inside and outside.

• Manually screw the choke tube clockwise in the barrel. Use the Beretta spanner provided to tighten the choke tube until it is fully bottomed into its seat in the barrel.

NOTICE: In the case of extended choke tube, after screwing it in position, you only need to tighten it manually with a certain force.

• Remove the spanner from the barrel after tightening.

WARNING: Periodically check that the choke tube is tightened correctly with the shotgun unloaded (empty cartridge chamber and carrier) and in the open position. If necessary, firmly tighten the choke tube with the Beretta spanner supplied. A correct tightening for the choke tube avoid the occurrence of damages to the shotgun or injury to persons.

WARNING: The choke tube must be inserted in the barrel and tightened correctly even during storage and cleaning. Cleaning the barrel without the choke tube installed may involve penetration of dirt in the barrel thread and cause wrong fitting of the choke tube, formation of rust or obstruction of the barrel.

WARNING: Never shoot a choke barrel without using the choke tube. Firing without the choke tube fitted to the barrel is very dangerous because particles of lead or debris might be trapped in the thread and obstruct the barrel. The absence of the choke tube can also irreparably damage the barrel thread and may cause erratic shot pattern.

Do not alter nor modify an existing fixed choke Beretta barrel for the use of interchangeable choke tubes. The resulting wall thickness would be too thin to safely contain the pressure levels generated by shooting.

At the end of a shooting day, clean and lubricate your shotgun. At the end of the hunting season, or annually, have your gun completely cleaned, including internal mechanisms, by a competent gunsmith. Proper periodic maintenance is important for the reliable functioning of any firearm.

Never spray or apply oil to the cartridges. Use lubricants properly. You are responsible for the proper care and maintenance of your firearm.

CAUTION: The hinge pin and locking areas are very important mating surfaces, The receiver, monobloc and fore-end iron are subject to very high loads. Improper lubrication of these components may cause seizing or malfunctioning. Always make sure that the lubricant is present as instructed.
