Discharging firearms in poorly ventilated areas, cleaning firearms, or handling
ammunition may result in exposure to lead and/or substances known to cause birth
defects, reproductive harm, and/or other serious physical injury. Have adequate
ventilation at all times. Wash hands thoroughly after exposure.
firing
With the firearm pointed in a safe direction and held in the proper firing position, move the safety
button fully forward to its “OFF” (FIRE) position. Pulling the trigger through its full travel to the rear
will cause the firearm to fire. Ensure muzzle is pointed in a safe direction before placing finger on
trigger.
Should the shotshell fail to fire, keep the firearm pointed in a safe direction and move
the safety button fully rearward to the “ON” (SAFE) position. Wait a few moments and
then remove the misfired shell and keep separate from other ammunition. Do not
attempt to refire a misfired round.
If at any time during firing, the sound of any shell is noticeably louder or softer than the
previous shells fired, STOP! Do not load or fire additional shells until you have put
safety in the “ON” (SAFE) position and safely unloaded your firearm. Inspect the
firearm for possible damage or obstructions in the chamber or bore. (The bore is the
inside surface of the barrel.) Firing the shotgun with a bore obstruction can cause
damage to the firearm and may result in serious personal injury to the shooter and/or
others nearby.
cycling The acTion
To eject a shotshell case, pull the forearm completely rearward. The spent case or
unfired shotshell will eject out of the receiver through the ejection port.
Be sure that all observers are clear of the path of ejection. Empty cases are thrown out
with significant force and could cause injury.
To chamber a live shotshell from the magazine, push the forearm fully forward.
Remember: when the magazine tube is loaded and the action is cycled, a live shotshell
will be chambered! Always keep the safety in the “ON” (SAFE) position until you have
actually decided to fire.
loaDing magaZine
Load the magazine tube by turning the shotgun so that the trigger guard is facing up and the
action is closed. Push the front end of the shell into the magazine tube until the rim of the shell
snaps past the cartridge stop (Fig. 6 & 9). Never attempt to exceed the magazine capacity.
