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.
