This is basically a “plug and play” installation. For Maximizer 2 and Maximizer 3 with an EZ-2S or EZ-3S controller; installation instructions are the same.
1. Disconnect GPS system from harness and remove. Cable has a 4 pin connector and is typically located inside the frame rail of the truck chassis. See picture 1
Picture 1
2. Locate an area on the chassis where the Radar Horn can be mounted so that the face of the sensor has an unobstructed view of the ground. Choose an area that will provide protection from damage. Avoid areas of high heat or high vibration. The Radar horn should be mounted so that the face of the sensor is from 18 to 48 inches above the ground.
3. Mount the Radar Horn facing parallel to the direction of travel and at an angle of 35 degrees with the ground using bracket (Leeboy #15716). See picture 2

4. Plug Radar Horn connector into the harness running through the chassis frame. The connectors are the same for GPS or Radar Horn.
Verify Calibration of Speed
The distributor tank must be empty. This procedure must be done in the “SPRAY” position but the spray bar does not have to be opened. If the tank has emulsion in it; the emulsion will gravity flow into the pump and spray bar.
1. Measure off 500 ft or more (it is best to measure 1000 ft if possible)
2. Select “MANUAL” mode.
3. Turn manual pump control to the center position or until screen shows 0 G.P.M.
4. Turn rotary switch to “SPRAY/BAR CRCLT” position.
5. Push all individual spraybar switches up to the “OFF” position.
6. Turn spraybar master switch to the “BAR CRCLT” position.
7. Select the “TOTAL” screen and push “TOTALS/CLEAR” switch up to clear totals.
8. With the truck in low gear; approach the start line. As you pass the start line; move the spraybar master switch to the down (“SPRAY or ON”) position. The screen should start to show total feet. At the end of the measured distance; move the spraybar master switch to the up position. (BAR CRCLT)
9. If the total distance on the screen is the same or very close to the measured distance; the unit will not need calibration. If the distance displayed does not correspond to the measured distance; proceed to the Calibrate Speed section and calibrate the unit.
Calibrate Speed
1. Turn system power “OFF”, hold the “SCREEN SELECT SWITCH” down while turning the system power back “ON” and then, release the “SCREEN SELECT SWITCH”.
2. Screen will show “CIRCULATE G.P.M. SET”.
3. Move “SCREEN SELECT SWITCH” down. Screen will display “TO CALIBRATE FLOW PRESS CLEAR”. Do NOT press “CLEAR”.
4. Move “SCREEN SELECT SWITCH” down again. Screen will display “TO CALIBRATE SPEED PRESS CLEAR”. At this point press “CLEAR”.
5. Screen will display “PRESS CLEAR TO START”. Do not press “CLEAR” at this time.
6. With the truck in low gear; approach the start line. As you pass the start line; then press “CLEAR”. The screen will display “PRESS CLEAR TO STOP” and the screen will start to display “TOTAL FEET”.
7. At the end of the measured distance press the “CLEAR” switch. The total distance displayed will stop and the screen will display “ENTER REAL DISTANCE”. At this point enter the measured distance.
8. After entering the “REAL DISTANCE”; the screen will display “THE NEW CALIBRATION SPEED CONST. IS ____” This number will not be the same on all units.
9. Push “SCREEN SELECT SWITCH” down until the screen displays “EXIT=PUSH DATA + SAVE=PUSH DATA -”.
10. Push “DATA UPDATE” switch down to save the new speed calibration number. The screen will display the original operation screen.
11. Check the speed calibration setting after the unit is calibrated by referring to steps 1 thru 9 above in the “VERIFY CALIBRATION OF SPEED” section.
Example:
Measure a course that is 1000 ft long.
Drive the truck in low gear through the 1000 ft measured course.
Press the “CLEAR SWITCH” to start the beginning of the 1000 ft measured distance.
Travel to the end of the measured 1000 ft distance and then press the “CLEAR SWITCH”.
If the screen displays 950 ft then use the “DATA UPDATE” switch to enter the 1000 ft value that is the measured length of the course.
