NOZZLE CHART
Correct nozzle size is important for optimum cleaning efficiency. Surface Cleaner Unit is shipped with two #2, 25°
nozzles in rotary swivel, and one #3, 15° nozzle in shut-off gun. Review correct nozzle size for your pressure washer.
See chart below for correct nozzle size. To obtain the correct nozzle size in the rotary swivel, divide the minimum
nozzle size for the pressure by two. Round this figure up to the nearest half nozzle size. These are the 1/8" nozzles
only (two needed) for the rotary swivel on the Surface Cleaner Unit.
