Hontai 805 Quadcopter

[Silverline102]

Hello,
I am new to this forum as well as to drones.
I just brought a Hontai 805 quadcopter. When I turn it on the lights flash, the control also come on, but I can't seem to get the rotors to start. I did it once when 3 of the 4 started spinning. The instructions says to pull the left lever to tye bottom left and the right lever to the bottom right and let them go and it should start spinning, but it has not been working.
Please advice on any problem solving techniques.
Thanks
