Should your tube be hangi ng low when the switch is flippe d, the gun may immed iately elevote ... which can smash up anythi ng under the breech , including somebody's leg. (You can get similar troubles if your contro l handle s are not in neutra l when the switch is flipped .)

Allowing the bore evacu ator to partial ly hang onto the end of the gun tube when remov ing it. This'll foul the thin seal on the rear inside of the evacu ator. When remov ing or installing the evacu ator, keep its center line paralle l with the center line of the gun tube.
