spray tips represented in the 844 Spray Control.
Color coding of spray tips is not uniform from manufacturer to manufacturer. Flow rates
for all nozzles should be checked prior to use. Tips that are worn should be replaced to
ensure an accurate application rate.
4. Feature: Based on the tip programmed and nozzle spacing, the 844 console will calculate the required
speed to achieve the application rate that was entered in the last programming step. The speed will be
displayed in the lower left corner of the display window. Keep in mind that this speed is based on a
spraying pressure of 40 psi. More calculations can be performed in the next programming step.
5. When the correct flow rate for the spray tips being used has been entered, depress the key to
accept the value and advance to the next step.
