Page 3: Safety Notes
Protect from sunlight and prevent exposure to temperatures exceeding 50’C. Keep out of reach of children. Discard used canisters in a safe place and do not puncture or incinerate, even when empty. Avoid deliberate inhalation. WREN 75 - High Performance Gas Turbine Engine Page... - Page 4 The mounting must be properly secured as the thrust from this small engine is considerable and users are asked to use “belt and braces” in mounting to avoid any possibility of the stand being pushed over WREN 75 - High Performance Gas Turbine Engine Page...
- Page 5 The outlet of the gas tank is fed via 3mm tube direct to the gas solenoid valve and the flow is then controlled by the screw-down valve on its outlet in the normal way. WREN 75 - High Performance Gas Turbine Engine Page...

The engine is supplied ready-to-run and has already been tested with all components supplied so you know it is properly prepared.

- Page 8 The tank does not need to be any more than about 1/3 full for several successful starts. Do not attempt to fill more than this as it is unnecessary and will not aid gas supply. WREN 75 - High Performance Gas Turbine Engine Page...

- Page 10 ECU needs this cycle to relearn the throttle stick position to rpm match and it is good practice to do this at the beginning of all engine runs. You can now explore the response time of the engine. All turbines have a throttle lag, but the Wren 75 is remarkably quick to respond. Shutting down.
