• Apply a thin film of good quality Gun Oil on the barrel thread and choke tubes. INSTALLING THE CHOKE TUBES WARNING: Check that the shotgun is unloaded (empty cartridge chambers). If it is loaded, unload following the procedure described in the relevant section. ! WARNING: Never look directly through the barrels from the muzzle and do not replace the chokes with the shotgun loaded even with the safety engaged. ! CAUTION: Check that the choke tubes are in perfect condition (not damaged) prior installing them. • Make sure the safety is engaged. • Pivot the barrels in a downward motion or remove them from the receiver. • Apply a thin film of good grade Gun Oil on the barrel thread and choke tubes. • Install the desired choke tubes after checking they are perfectly clean inside and outside. • Manually screw the choke tubes clockwise in the barrels. Use the Beretta spanner provided to tighten the choke tubes until they are fully bottomed into their seats in the barrels. NOTICE: In the case of extended choke tubes, after screwing them in position, you only need to tighten them manually with a certain force. • Remove the spanner from the barrel after tightening. WARNING: Periodically check that the choke tubes are tightened correctly with the shotgun unloaded (empty cartridge chambers) and in the open position. If ! necessary, firmly tighten the choke tubes with the Beretta spanner supplied. A correct tightening for the choke tubes can prevent the occurrence of damages to the shotgun or injury to persons. WARNING: The choke tubes must be inserted in the barrels and tightened correctly even during storage and cleaning. Cleaning the barrels without the ! choke tubes installed may involve penetration of dirt in the barrel thread and cause improper fitting of the choke tubes, formation of rust or obstruction of the barrels. WARNING: Never shoot a barrel that is threaded for a choke tube 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 barrels for the use of interchangeable choke tubes. The resulting wall thickness would be too thin to safely contain the pressure levels generated by shooting. 54

Install the desired choke tubes after checking they are perfectly clean inside
and outside.
• Manually screw the choke tubes clockwise in the barrels. Use the Beretta
spanner provided to tighten the choke tubes until they are fully bottomed into
their seats in the barrels.
NOTICE:
In the case of extended choke tubes, after screwing them in position,
you only need to tighten them manually with a certain force.
•
Remove the spanner from the barrel after tightening.
WARNING:
Periodically check that the choke tubes are tightened correctly with
