Did he start it with the rotor brake on? Granted I don't know this helicopter. Does it have a clutch or did he start it with the brake on, if he did it's a damn good way to burn up a turbine.
The clutch is manually engaged by increasing engine RPM, and is centrifugal. Rotor brake can be on when engine is idling. You just need to disengage the rotor brake before moving throttle from the rearmost idle position.
