Water Distribution Chart. The water distribution chart is attached to both of the control panels. These charts
provide water usage rates based on various combinations of truck engine speed, truck transmission gear selection, water
distributor engine speed, and one or both spray nozzles open. The card contains a chart for each of the three truck-
tractors that may be used to tow the water distributor (M916, M920, and M123A1C).
Water Distribution Charts
(1)
Choose the chart for the appropriate truck-tractor.
(2)
Select the application rate (in gallons per 100 feet of travel) which most closely matches the
desired application rate.
(3)
After the application rate has been selected, look at the top of the chart to determine the
transmission gear and engine speed for the truck-tractor. Look to the left of the selected application rate to determine the
proper water distributor engine speed and the number of nozzles to open.
