INSTRUCTION MANUAL AND PARTS LIST
WATER JET SYSTEM Manual • #96-617 • Rev 12/03
NOZZLE CHART
Correct nozzle size is important for optimum cleaning efficiency. Water Jet is shipped with two #3, 15° nozzles in rotary swivel,
and one #6, 40° 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 Water Jet.
