PRE-ISSUE INSPECTION

Before each use, the system must be given a thorough visual inspection and
functional test. NEVER use an EBIS which shows signs of damage, leakage
or substandard performance until it has received inspection and service from
a factory trained service technician.
1. Carefully inspect the first stage to
make sure all external components (dial
pressure gauge, dual swivel, safety plug,
etc) are properly secured. Ensure the
safety wire is firmly attached and in good
condition (Fig. 22).
WARNING:
An inspection must be performed and the safety wire replaced prior to issue.
2. Ensure the medium pressure hose is securely connected to the second stage. Inspect
the hose and hose fittings to ensure that there is no blistering, cuts, or corrosion present.
3. Verify the inflator hose is securely connected to the inflator mechanism and the heat
shrink seal is in place and not damaged. Check the inflator hose is firmly attached to
the QD fitting. Inspect the entire length of the inflator hose, along with the upper and
lower inflator tubes to ensure there is no blistering, cuts or damage present.
4. Visually inspect the entire system for any external damage, such as dents, gouges,
cracks or external corrosion.
5. Confirm the handwheel is closed and the system depressurized. Inspect the
dial pressure gauge to ensure that it reads "0 PSI / BAR" (Fig. 23).
0 PSI / BAR
DO NOT issue an EBIS if the safety wire is missing or damaged.
