 TO REMOVE/REPLACE BASE PLATE

To remove, first remove the shield.  Remove 
two screws from each base plate with a flat 
blade screwdriver or a coin 

.  Remove 

plates from helmet shell.  Note the right and 
left base plate for proper reinstallation.

 

To replace, place base plate over the threaded 
screw receptacles in the helmet.  Install the 
two screws through each base plate into the 
helmet finger tight 

, do not fully tighten.  

Install shield, lower the shield to fully closed 
position and press the front center of the 
shield to bring it against the eyeport trim.  
While still pushing on the shield to keep a 
tight seal against the eyeport trim, tighten the 
base plate screws 

③ 

– but be careful not to 

overtighten, as the screws may break.  It may 
be necessary to do one side at a time, with 
a smoothing pressure from the shield center 
toward each base plate and tightening one 
and then the other for best results.

To remove the tether connecting the side pod 

and base plate, compress the tether spring hook 

at the side pod. 

Pull the tether out from the slot .

To remove tether from the base plate, remove 

base plate from helmet.  Pull tether until it stops, 

then bend it toward the back of the base plate 

to release it.

To reinstall, reverse the removal procedure.
