Yong Heng Will Not Turn On

Received a yong heng in the mail yesterday. When I first turned it on it paused for a second and then started. Filled up my gun just fine. Came back an hour or two later and it once again paused before starting.

This morning I turned it on and it took 10 seconds to start up. Now it has nothing. Wont turn on at all.

I just went and turned it on again. It clicked about three times in the switch and then turned on.

Any suggestions?
 
Two things, make sure the outlet is a 30 amp circuit like on a washing machine, and open the bleed valve when starting. Also because the second stage seals are brand new and haven't worn in yet the piston will be very tight, if pump doesn't start emedietly turn it back off wait a moment and try again. It's not a good idea to leave the pump stalled when trying to start up, could cause damage.
