• First, check whether your battery has been locked. Rapidly click the power button 5 times to lock or unlock the battery. 


• Next, check whether the power indicator lights up when you press the power button. If it doesn’t, and the battery is not locked, check to see whether the battery needs to be charged. 


• If the power indicator light does come on, but the battery doesn’t fire the tank, check to see that all connections and threads are clean and free of any dirt or residue. 


• Make sure the tank is turned to the locked position. 


• If you haven’t already done so, replace the coil in your tank and try it with the battery again. 


• If the above doesn’t resolve your issue, get in touch with our customer service team.
