SECTION 3 - SPRAYER OPERATION
SCS-205 Control has Mechanical Pressure Sensing (Less Pressure Transducer).
12’ extension cable assemblies are available.
Order PN 8A1285 for SCS-205 Control.
Order PN 8A4340 for SCS-450 Control.
11. ELECTRIC - HYDRAULIC TIP LIFT ON TRUCK SPRAYERS
The electric-hydraulic tip lift is a self-contained hydraulic system. It requires little maintenance other than clean oil filled to
the proper level, a good 12-volt power source, and a secure ground.
3.3 INITIAL SETUP OF SPRAY SYSTEM
1. DETERMINE TIP SIZE
Determine tip size by examining a nozzle tip for the stamped number.
2. DETERMINE APPLICATION RATE
a. Choose a desired ground speed within factory recommended range of 4 to 12 miles per hour (mph).
b. By knowing tip size and desired ground speed, refer to English or Metric Application Rate Chart (shown
on following pages) to determine application rate (U.S. gallons per acre or liters per hectare) based on
different operating pressures.
c. Example of how to obtain 5.0 U.S. gallons per acre application rate:
1. Determined tip size to be XR8001.
2. Select a desired ground speed of 6 miles per hour (mph).
3. Refer to English Application Rate Chart (shown on following page) to see that XR8001 tips traveling at
6 mph will deliver 5.0 U.S. gallons per acre at 40 psi operating pressure.
d. Spraying solutions other than water: All tabulations in this manual are based on spraying water, which
weighs 8.34 lbs per gallon. Conversion factors must be used when spraying solutions that are heavier or
lighter than water. To determine the proper size nozzle for the solution to be sprayed, multiply the desired
rate by the conversion factor. Then use the new converted GPM or GPA rate to select the proper size
nozzle.
