Removing the shield on Mach V or Delta V Commander Helmet:

So, pretty easy process. If you just start by opening your shield, this typically works with the helmet facing towards you. Reach down here and you’ll look actually on this shield base plate. 

We have a little trigger, a little shutter you can get your fingernail on. Pull that towards you, it actually releases this part of the shield that pops off at the pivot point. The detent, or knob to the inside of that pivot point will pop out as well. 

Repeat on the other side. Again, grab this little release, pull towards you, and it will pop out. Shield is removed, simple as that.

Replacing the shield n Mach V or Delta V Commander Helmet :

Take your replacement shield, offered in various colors, tints, and mirrors. 

Again, works best when the helmet’s facing forward or towards you, I should say. 

Simply align that peg that pops out in the last shield with the hole on this shield base plate. And the detent (knob) in the semi circle opening at the top of that shield plate. You should hear a click to know it is flush against the helmet shell. This is important to ensure the shield is properly placed to avoid any closing or breaking issues for the shield. 

Line those up, simply press into place. 

This is spring activated, so that jaw essentially will grab that peg and hold the shield in place. Turn around, again press it into place. Spring loaded, so it’ll grab itself. Both shields, good to go.
