Yong heng compressor help

Sometimes they are a bit reluctant to start for their first time. Try getting something through the guard and turning the fan a bit then try it powering it up again If that doesn't werq for you you should probably be contacting whoever you bought it from.

Like Odoyle says make sure you have a dedicated outlet with nothing else on the circuit these things are power hungry on start up. Don't use an extension cord unless it is rated for more than 15amps continues duty either.
