The Excellent 160 and 170 pressure washers come with a 3-in-1 Multipurpose nozzle. If you want to remove the 3-in-1 nozzle from the lance or re-connect it, you need to ensure the nozzle is on the Rough setting and not on Gentle 1 or Gentle 2. To put the lance on the rough setting, the small and large dot should be aligned.
