No. Yeah, this one's a major safety hazard. Never run it in an enclosed area like a garage, even with the door partially open. The exhaust contains poisonous carbon monoxide gas, which can build up rapidly and cause unconsciousness or death.
Always start and operate the engine outdoors in a well-ventilated area. For easy restarting and max performance from the Auto Choke System, let the engine run for at least three minutes after starting before you begin mowing.
Heads up: The same goes for refueling. Gasoline vapor can explode. Refuel outdoors with the engine off. Never smoke near it.
