CAUTION: Never close the action or pull trigger while barrel is removed as damage
could result to the firearm.
To facilitate shipping, some models are packaged with the barrel removed. To install the
barrel in the receiver, proceed as follows:
Visually inspect the inside of the barrel to make certain it is free of any
obstructions, excessive oil or grease before installation. If you are unable to
remove all obstructions, bring the shotgun to a qualified gunsmith or ship it to the
authorized Product Service Center. Obstructions of any kind may result in
firearm damage and/or serious personal injury to the shooter and those nearby if
the shotgun is fired.
Move the safety button, fully to the right, to the “ON” (SAFE) position (Fig. 2).

the front of the bolt is in the middle of the ejection port (Fig. 7).
