*Manual Safety: The manual safety is the lever that is in front of the trigger, if you pull it forward, the safety is off, if you pull it backwards (towards the trigger), the safety is on. Please make sure you do not turn the safety off until you are ready to shoot.
Automatic Cocking Safety System: The automatic safety cocking system is a different safety feature than the Manual Safety; it does not allow you to pull the trigger while cocking the air rifle. When you break the barrel this safety system is engaged and when you put the barrel back into position this safety system is disengaged.
Please read the manual before using.
