5.17 GROUND SPEED CONTROL
This water truck may have a variable speed option
for the water pump, or Ground Speed Control. This
allows the operator to set water distribution to match
the ground speed of the chassis, avoiding over-water-
ing at low speeds or incomplete coverage at higher
speeds.
To adjust variable speed settings, the chassis engine
must be running and the parking brake set.
Press buttons 1, 3, 4 & 5 at the same time to open
the calibration settings page. Release the parking
brake and drive forward at the slowest speed you will
be using while watering.
Press the Min Driving Speed button.
Accelerate to the fastest speed you will be using
while watering.
Press the Max Driving Speed button.
Using the sliding bar, adjust the upper and lower water
output levels. If the ground travel speed is below the
minimum set driving speed, the water pump output
will be the lowest level set.
If the ground travel speed is above the maximum
level set, the water pump output will be the upper
limit set.
Once the speeds and water pump output levels are
set, press X to return to the main screen and begin
watering operations. The settings will remain saved
in the Water Control System the next time the water
truck is operated.
