    UMP SAFETY RULES
    Safety Rules on the use of the HK UMP Submachine Gun
    Clear the weapon! Before handling the weapon, “clear it!”  Do so
    by:
    • Make sure fingers are outside of the trigger guard and the
    weapon is pointed in a safe direction at all times!
    • ON SAFE – Rotate the safety/selector lever to the “Safe”

    • REMOVE MAGAZINE – Depress the magazine release lever and
    remove the magazine from the magazine well.
    • COCKING LEVER – Rotate the ejection port towards the ground
    and pull the cocking lever rearward one or more times to insure
    the chamber is empty. Watch for a live round or empty case to
    be ejected. Rotate the cocking lever upward slightly and lock it
    into the indent in the cocking lever housing to lock the bolt
    open.
    • INSPECT CHAMBER – Inspect chamber for the presence of a
    live round or empty case.
    Visually – View chamber through open ejection port.
    Physically –  Insert index finger through magazine well or

    case in the chamber.

    from within the weapon or magazine before handling the
    weapon further.
