Securing the BC to the Cylinder

F

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 factory. If rethreading is necessary, follow the procedure in the next section,

“Threading the Cylinder Band.”

Remove band from outer slot

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 cylinder 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.

WARNING: The cylinder band will initially stretch as it becomes wet. Always wet the band before making the final adjustment; apply enough tension to ensure that the cylinder 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.
