Securing the BC to the Cylinder
Note: BC cylinder bands adjust for all standard cylinder diameters:
6.9” (17.5 cm), 7.25” (18.5 cm), and 8.0” (20.3 cm). The cylinder
bands are properly threaded to the buckles when the BC leaves the fac-
tory. If rethreading is necessary, follow the procedure in the next section,
“Threading the Cylinder Band.”
1. Remove the free end of the cylinder band
from outer slot on the buckle (Fig. 4).
2. Wet the cylinder band and then slide it
over the cylinder so that the BC is at the
desired position in relation to the cylinder
valve. Make sure the cylinder valve air
outlet is facing the back of the BC. While
holding the cylinder secure, pull the free
end of the cylinder band until there is a
very tight fit between the pack and the
cylinder (Fig. 5).
3. Close the buckle halfway to hold the cyl-
inder band taut (Fig. 6a), and thread the
free end of the band through the open
slot in the end of the buckle (Fig. 6b).
4. Pull the cam buckle closed so that it lies
flat against the cylinder. Secure the end
of the cylinder band with the hook & loop
attachment.
5. Test the tightness by pushing/pulling the
back frame and cradle. Tighten and se-
cure the weight pocket strap.
WARNING: The cylinder band will initially stretch as it be-
comes wet. Always wet the band before making the final
adjustment; apply enough tension to ensure that the cylin-
der is completely secure. Test this connection before every
dive. If the cylinder slips free from the BC during the dive,
you may lose your air supply, which could lead to serious
injury or death.
