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.
