1. To operate the launcher, remove the black Schrader valve cap and connect a manual tire pump.
2. Load the rocket over the launch tube.
3. Slide the blue part of the slide valve in the direction of the arrow that shows “Pressurize” (away from the pump, towards the launcher).
4. Pump to desired pressure – check the gauge on your pump. Lower pressures (10-30 PSI) for large indoor spaces such as a gym. Higher pressures up to ≈120 PSI (where the overpressure valve will leak) outdoors.
5. When using with children, it is best to locate the launcher on a table, with the launch tube angled down range, so the rocket launches over the length of the table. The table prevents people from getting too close or leaning over the launcher.
6. Do a countdown, and slide the blue part of the slide valve away from the launcher. You will hear a hiss as the air escapes the orange tube, triggering the QEV to open in about 1 millisecond, venting the charge of air from the tank and launching the rocket!
To store or transport, make sure pressure tank is discharged by pulling on the ring at the end of the over pressure valve to vent any residual pressure. Unscrew and slide the launch tube into the larger notch in the base, and secure with Velcro strap. The smaller notch in the base is for a 3/8” launch tube which works with standard stomp rockets. A length of 3/8” pipe and a ½ NPT male to 3/8 NPT female adapter is required to use that size launch tube.
