Is this a karcher hds unit?
There is a device by the air intake that looks like a semi-circle. This adjusts the air flow to the burner chamber. You can adjust this according in order to get rid of the smoke but you have to get it right in order not to have to much air in order to blow out the flame.
If this does not work you may have to clean out the fuel injector and housing. Then if it continues you may have to clean the exterior of the coil.
If you are to clean the exterior of the coil make sure you take the cover off from the bottom three bolts (bolt on to base of machine) and not the three bolts at the top of the housing(were fuel injector is). You can use a karcher product called RM 81 which acts as a degreaser and pressure wash the coil( making sure all electrics are covered up).
I have come accross this a few times as the injector sprays diesel on the coil if the air flow is not fixed correctly and then the smoke you are seeing is the machine burning off the diesel that is on the coil.
