When using "Turbo Mode" for the first time, press and hold to disable the 30-second auto shut-off function. Keep in mind that the motor will heat up quickly in Turbo Mode, and after 10 seconds, overheat protection will kick in, causing the motor to stop until it cools down. Since the turbo fan generates strong suction at high speed, make sure to keep the exhaust port clear of any foreign objects to prevent damage.
