Pressurising the dart:
Hold the dart vertical with the needle/protection cap uppermost. Mount the DANiNJECT coupling adapter onto a dry standard 12 - 20 ml syringe. Introduce 13 ml of air into the syringe, (correct air pressure for a 3 ml dart).
Connect the syringe securely to the air chamber of the dart and, with a smooth continuous action, inject the 12 ml of air into the dart air chamber.
Now 13 ml of air is let in to the syringe though the coupling. The red plunger will act as a non-return valve and retain the air within the dart.
WARNING: THE DART IS NOW PRESSURISED AND EXTREME CAUTION MUST BE EXERCISED AT ALL TIMES. SAFETY CRITERIA MUST BE ADHERED TO
