Before you plug in verify the 30 amp connector is 120 volts fed by a single breaker. Also check polarity. Notorious for being wired wrong.

Get a 100' extension. Check your running voltage the first few days. 108+ is fine. Some dip at start up is ok.

For best power get or make an extension with 30 amp connectors and #10 wire.
