The color of the smoke will tell a lot. Typically, black smoke will be a fuel problem and white smoke will be an oil problem.
With that machine being new I would suspect some white-ish smoke as the unit is new and there will be oil in the engine head area and muffler that is put there when made to prevent rust. Some mufflers also have a coating that burns off after a few minutes of use. The coating is there to prevent rust as well.
If the machine had fuel in the tank while in transit from the store to your home; that could have caused some fuel to seep into the head and now the engine is smoking while it burns that off.
In general, any smoke on a new machine should go away after about 10 minutes of fun time at full throttle.
If after that amount of time you still have smoke I would check to make sure the oil isn’t overfilled. If that looks good and you still have the smoke you might want to get a technician to come take a look at the machine. With it being new, I cannot see it being anything serious.
