Here is a quick guideline to getting your truck mounted Site Spreader up and running when it is equipped with the automatic controller. This can also be found in the Resources section of our website here: http://www.stoltzspreaders.com/resources/science-best-practices.php.
Filling The Spreader:
-Close the rear gate
-Close the butterfly valve on the bottom of the filter can (if equipped) or open the lids over the pop up bags and pull the bags out.
-Connect the fill hose and begin to fill.
-Keep line and tanker pressure below about 8 psi.
Spreading in Automatic Mode:
-Set your desired spreading rate in pounds per square yard (kg/sq meter) in the console.
-Hold the Open Gate button until the gate gets to about 8-10 inches (200-250 mm) for a typical rate.
-Enable Auto Mode.
-Press Start. The spreading auger will turn on automatically. Note that the PTO must be engaged!
-Start driving. The drag chain will start discharging material when the truck starts moving.
-Keep an eye on the “Alarms” section of the display. If it says “OVERSPEED”, the hydraulic system cannot keep up. Select a lower gear, raise the gate, or select a lower target spread rate.
-Press Stop when done spreading.
After spreading, visually check to see if the depth of material is uniform from edge to edge. Adjust the openings in the cross auger to achieve a uniform spread pattern.
Calibrating the Spreader:
This spreader is calibrated by changing the Material Cal Number in the Auto Mode Setup screen.
-The spreading auger must be manually adjusted to achieve a level spread pattern. Do a few short test runs and adjust the openings in the auger to achieve a full width, level spread pattern.
-Place the 1 sq.yd. tarp about 30 feet in front of the spreader.
-Spread over it while in Auto Mode.
-Weigh the loaded tarp with the hanging scale.
If the application rate is not correct, change the Material Cal No. according to the following formula:
New Material Cal No. = Current Cal No. X Actual Application Rate (Amount on Tarp) / Desired Application Rate
Alternatively, if you have measured out how far you expect your load to spread, you can use the following formula:
New Material Cal No. = Current Cal No. X Expected Distance / Actual Distance Spread
Note: Decreasing the Cal No. will increase output while increasing the Cal No. will decrease output.
