1. With the cartridge body removed from the TRM, place the TRM protrusion gauge over the firing pin.

2. Check the position of the inner center shaft of the gauge. It must be flush or slightly above the outer case of the gauge.

3. If the firing pin fails this test, it must be replaced.

FIRING MECHANISM COCKING TEST.- To complete the firing mechanism cocking test, you should perform the following steps in sequence.

1. Place the TRM clamp in a vise and position the TRM on the clamp. Screw the TRM cocking handle into the base of the TRM. Pull the cocking handle until the firing mechanism is fully extended.

2. In this position, install the test firing pin into the time-delay g-sensing release mechanism. The test firing pin is furnished as part of the TRM test set.

3. Release the tension on the cocking handle. Ensure the mechanism is cocked by pulling on the test firing pin. If the firing mechanism is cocked, it will be held firmly in place.

4. Remove the cocking handle from the TRM. Then remove the TRM from the clamp. The TRM is now cocked and ready for the barostat test check out.
