RUN THE FAN Before you run the fan make sure that e The motor selected is one of the recommended motors e An appropriate ESC is being used e An appropriate LiPo battery is being used e All the screws and set screws are secured with threadlocking compound e All the fan parts are properly attached to the fan and to the airframe e If any part of this fan should become damaged replace all parts Never attempt to repair damaged parts e Keep the fan away from objects as it will try to suck them in which can cause damage to the fan and or bodily injury e Always use eye protection when operating the fan unit e NEVER look into the fan as it is running e Ensure all persons in the immediate area are using eye protection while the fan is in operation e NEVER point the fan in the direction of anyone e Make sure you inspect the fan and all its parts before each run e Never use motors larger than those recommended e Never run a fan that is damaged in any way e Never run the fan while holding it in your hands e NEVER run the fan above 50 000 rpm e Never run the fan rotor on any motor outside of the housing This is a device that runs at very high rom and as such it needs to be handled carefully There is a very short break in period that needs to be followed to ensure that all parts fit well everything is tight and that no excessive vibration is present when running the fan Also if the power system chosen has
