GAS INFLATION SYSTEM

6 - 5
Warning: The charged gas cylinder can become a lethal projectile if discharged to
atmosphere when not fitted with a diffuser cap. Always fit diffuser caps to a
cylinder valve outlet when handling a fully charged cylinder.
1. Inspect hoses and non-return valves for visual defects and security.
2. Weigh the cylinder and check it against the weight marked on the cylinder. Refer to Table B in
Chapter 8 – Assembly for information on weight tolerance.
Note: The charged weight does not include the weight of the bleeding down tool or a
diffuser cap, and due allowance for these items must be made when checking
the full weight.
3. Check that the syphon tube (IPL Fig. 2, Item 30) inside the cylinder is still serviceable. Shake the
cylinder, if the tube is still flexible it will strike the wall of the cylinder with a ringing sound. If
there is a noticeable delay before the sound is heard, the tube has stiffened and is no longer
serviceable. The cylinder must be rejected.
Note: Refer to Chapter 8 – Assembly for recharging instructions. If a cylinder is to be
recharged, it is imperative that the correct quantities of CO
2
/N
2
gas are
achieved.
4. Check the date of the last hydrostatic pressure test. (Refer to Chapter 4, Testing)
Note: Hydrostatic testing is required by the DOT within the past 5 years before a
cylinder can be recharged.
Note: A cylinder valve inflation test will need to be performed at every other
inspection (6 years).
Note: Perform a hydrostatic test and overhaul the cylinder valve after every cylinder
valve inflation test.
5. The external condition of the cylinder must be checked. (See Chapter 8 – Assembly for details)
