The fire starter is equipped with 2 working modes: Heat + blower mode - will heat the air and increase the temperature around the nozzle tip, therefore ignite the fuel. Blower only mode - will increase the airflow and spread the heat after the fuel is ignited, to create strong flame. Adjust the unit's mode with the mode switch next to the power switch. Slide it forward to set the fire starter to heat + blower mode. Slide it backward to set the fire starter to blower only mode.
