TROUBLE SHOOTING

If the tensioning screw wheel has unscrewed from its 
post

, it can be re-screwed into place. Hold the mask shell with 

your thumb inside the shell, pressed against the base of the post; 
grasp the dual beam element with your fingers, as illustrated, and 
replace the tensioning screw inside its slot, perpendicular to the 
post. Turn the screw clockwise until it threads on the post.

6.  Leaks are eliminated by applying moderate pressure along 

the embedded wire to bend the mask shell to match their 
facial contours and reduce air leaks. Adjust straps and mask 
shell as needed.

 

When bending the mask shell, support the opposite side of 

the mask so that adjustments only affect a specific part of 
the shell. 

7.  If necessary, pull the mask away from face and reset on face; move mask 

higher or lower; adjust strap lengths or upper strap position through headgear 
frame.

Retaining Clip

Elbow Assembly Lip

CORRECT

Not all Mojo masks feature a retaining clip. If your mask 
does feature a retaining clip, and the mask elbow has 
come off the mask

: you will need to re-insert the retaining clip 

between the mask shell and the lip of the elbow assembly. Cup the 
mask shell in your hands and support the mask elbow and swivel 
with your fingers. Use your thumbs to press the retaining clip under 
the lip of the elbow assembly, inside the mask shell. Ensure the clip 
is secure between the lip of the elbow and the mask shell. If the 
elbow assembly can rotate without popping out, then the retaining 
clip is correctly in place.
