5. Operating the Blaster
5.1 Powering On and Firing
- Ensure eye protection is worn.
- With the loaded magazine inserted, locate the acceleration trigger (usually a small button or lever near the main trigger).
- Press and hold the acceleration trigger to power on the motor. You will hear the motor rev up.
- While holding the acceleration trigger, pull the main trigger to fire a round. The Hera MXVII-1200 is semi-automatic, meaning one round is fired per pull of the main trigger.
