,.. SAFETY WARNING: Failure to obey a safety warning may result In Injury to you or
T to others.
INSTRUCTIONS FOR THE MODEL 1400
~ CAUTION-ALWAYS KEEP THE
T MUZZLE POINTED IN A SAFE DIREC-
TION. Prior to using live ammunition, famil-
iarize yourself thoroughly with these operat-
ing instructions. Get accustomed to the feel
of your new gun
to operate the action, to pull the trigger and
above all, KNOW THE LOCATION OF THE
SAFETY which, on this shotgun, is on the
trigger guard. The safety is placed in the "on"
position when pushed from left to right until
the red "warning" ring disappears. When the
red ring is visible on the left side of the
safety, it is in the "off" position, and the gun
is ready to fire. The safety can only be placed
in the "on" position when the hammer is
cocked.
~;'~'N~~~KEEP YOUR FINGERS CLEAR OF
T THE EJECTION PORT. The breech
bolt on the Model 1400, like most all auto-
matic actions, is under strong spring tension
and closes very swiftly. If closed on a finger,
it will cause a painful injury.
~;,~...~~~ IMPORTANT- CLEAN THE INSIDE
.
OF THE BARREL AND CHAMBER TO
T
REMOVE ALL GREASE AND OTHER POS-
SIBLE OBSTRUCTIONS BEFORE FIRING
YOUR GUN.
HOW TO CARE FOR YOUR MODEL 1400-
Protect your gun with good gun care prod-
ucts. Give it regular attention, and it will pro-
vide you with many years of shooting fun.
REMEMBER
sure all exposed metal surfaces are coated
with a film of oil. After being subjected to
damp weather thoroughly wipe out the bore
and wipe off the metal surfaces. Then apply
a new film of oil. If exposed to a soaking rain,
snow or salt spray a more thorough cleaning
and oiling may be necessary, requiring re-
moval of the trigger guard and breech bolt
assemblies.
~l~"'~~~Between seasons, apply a coat of
fabric or material which will absorb the lub-

grease to the bore and metal parts and

5. Remove the ejector (the flat spring like
piece that fits along the inside wall of the re-
ceiver) by bending the rear section of the
ejector inward just enough to disengage the
small retaining pin in the side of the receiver.
Pull the ejector out the barrel hole in the front
of the receiver.
:;;~'N~~~ 6. THE PISTON IS UNDER SPRING
T TENSION. WITH THE GUN UPRIGHT
AND THE MAGAZINE POINTED IN A SAFE
DIRECTION, insert a screw driver or a suit-
able rod into the coils of the closing spring
at the forward end of the slot in the top of the
magazine tube. Draw back on the tool reliev-
ing the tension from the piston. While holding
the spring compressed, remove the piston
pin that connects the slide arms to the piston.
Place.your free hand over the end of the mag-
azine tube, then remove the tool from the
coils and withdraw the piston and closing
spring from the end of the tube. Disconnect
and remove the slide arms from the receiver.
7. Remove the cocking handle bridge screw
(the screw in the underside of the bolt as-
sembly). The firing pin is under spring ten-
sion and will snap out of the rear of the
breech bolt when the cocking handle bridge
is lifted from the breech bolt slide. Remove
the firing pin and spring.
8. Slide the breech bolt with the cocking
handle to the rear of the receiver. Grasp the
cocking handle and by tipping and manipu-
lating the handle, remove the cocking handre
bridge out through the ejection port in the
receiver. Now the breech bolt assembly may
be lifted out or slid out the front of the re-
ceiver. For routine cleaning no further dis-
mantling is necessary.
TO REINSTALL THE BREECH BOLT
ASSEMBLY
1. Insert the breech bolt assembly through
the front of the receiver and move the as-
sembly to the rear of the receiver. Holding
the cocking handle, insert the bridge section
in through the ejection port. Then by tipping
and manipulating the cocking handle place
the bridge into position on the breech bolt
slide. Slide the assembly forward in the re-
ceiver, then lift up the rear of the cocking
handle bridge and insert the firing pin with
the firing pin spring into the back of the
breech bolt. When the firing pin is in posi-
tion lower the rear of the bridge so the tail of
the bridge enters the groove in the firing pin,
to hold it in place. Next, install the bridge
screw, securing the bridge to the bolt slide.
2. Insert the slide arms into the receiver and
connect the arms with the matching notches
in the cocking handle bridge.
3. Place the end of the closing spring having
the smaller coils into the end of the magazine
tube. Place a screw driver or a suitable tool
into coils of the closing spring through the
forward end of the slot in the tube and be-
tween the slide arms. Position the piston into
the tube so the 3 holes in the piston are up
and with the larger single hole to the rear.
0;~'N~~~WITH THE MAGAZINE POINTED IN A
T SAFE DIRECTION, draw back on the
tool, compressing the closing spring. Align
the larger hole in the piston with the hole in
the forward end of the slide arms. Insert the
piston pin through the hole in the slide arm
and into the piston. Then remove the tool re-
leasing the spring.
HOW TO INSTALL THE EJECTOR
the bowed side toward the breech bolt, slide
the flat end of the ejector through the barrel
hole in the receiver and down between the
breech bolt slide and the left inside wall of
the receiver. Bend the rear of the ejector
slightly inward and connect the ejector with
the retaining pin in the side of the receiver.
