NOTE: Remember, adjusting the shoulder straps too tightly will transfer
the cylinder weight from the hips onto the shoulders, and may restrict
your arm movement.

5. Readjust the cummerbund, if necessary, so that it is comfortably snug but
not restricting, with an overlap of at least 3 inches. Fasten together the
male and female side-squeeze buckles of the outer waist strap over the

NOTE: Your BC is equipped with an elastic outer waist strap. It can
be adjusted inside the BC, behind the cummerbund, so that it will be
snug when fastened. This will help your cummerbund to remain snug
when your wetsuit becomes compressed at depth, and can also help
prevent squeeze when your BC is inflated on the surface.

6. Fasten the sternum and waist straps, if equipped, and pull the free ends
until they are comfortably snug but not restricting.

WARNING: Be sure to avoid over tightening your BC’s adjustments.
Check to ensure that you can move your arms comfortably and take
deep, full breaths. Over tightening can restrict your respiration and
blood circulation, which can lead to serious injury or death.

Pre-Dive Inspection

Before each use, the BC must be visually inspected and tested. NEVER dive
with a BC that shows any signs of damage to its air cell or valves until it has
been serviced by an Authorized XS Scuba Dealer.

Inspection Checklist:
1. Connect the power inflator to a clean air source via the LP quick disconnect
hose. Depress and release the inflator button intermittently to ensure that
the airflow is unobstructed, and that the airflow stops completely when the
button is released.
2. Ensure that the air cell does not contain any water from a previous dive or
from internal rinsing. An excessive amount of water inside the air cell can
reduce the BC’s internal air volume and lift capacity.
3. Manually operate the lower overpressure valve (OPV) by pulling on the
attached ball and cord to release air from inside the BC, and then fully
inflate the BC until the shoulder OPV valve opens. Examine the operation
of the shoulder OPV valve by repeatedly inflating the BC to ensure that it
opens to relieve excess pressure, yet close immediately afterward to allow
the air cell to remain fully inflated.
