INTRODUCTION

Safety rules - Ecology and the environment Soil, air, and water are vital factors of agriculture and life in general. When legislation does not yet rule the treatment of some of the substances required by advanced technology, sound judgment should govern the use and disposal of products of a chemical and petrochemical nature. NOTE: The following are recommendations that may be of assistance: • Become acquainted with and ensure that you understand the relative legislation applicable to your country. • Where no legislation exists, obtain information from suppliers of oils, filters, batteries, fuels, antifreeze, cleaning agents, etc., with regard to their effect on man and nature and how to safely store, use, and dispose of these substances. • Agricultural consultants will, in many cases, be able to help you as well.

Helpful hints • Avoid filling tanks using cans or inappropriate pressurized fuel delivery systems that may cause considerable spillage. • In general, avoid skin contact with all fuels, oils, acids, solvents, etc. Most of them contain substances that may be harmful to your health. • Modern oils contain additives. Do not burn contaminated fuels and or waste oils in ordinary heating systems. • Avoid spillage when draining off used engine coolant mixtures, engine, gearbox and hydraulic oils, brake fluids, etc. Do not mix drained brake fluids or fuels with lubricants. Store them safely until they can be disposed of in a proper way to comply with local legislation and available resources. • Modern coolant mixtures, i.e. antifreeze and other additives, should be replaced every two years. They should not be allowed to get into the soil, but should be collected and disposed of properly. • Do not open the air-conditioning system yourself. It contains gases that should not be released into the atmosphere. Your NEW HOLLAND dealer or air conditioning specialist has a special extractor for this purpose and will have to recharge the system properly. • Repair any leaks or defects in the engine cooling or hydraulic system immediately. • Do not increase the pressure in a pressurized circuit as this may lead to a component failure. • Protect hoses during welding as penetrating weld splatter may burn a hole or weaken them, allowing the loss of oils, coolant, etc.

Autoguidance sensors - Clearance - Manual override sensor Follow the instructions below to check the clearances for the manual override sensor on Tier 4 T8 and T9 series tractors. 1. Ensure that the steering wheel does not rub on or bind with the Forward Neutral Reverse Park (FNRP) pod. 2. Remove the steering wheel. 3. Remove the screw that secures the top half of the FNRP pod to the lower half of the FNRP pod.

RAIL13PLM0003AA

RAIL13PLM0004AA

RAIL13PLM0005AA

4. Remove the top half of the FNRP pod.

5. Inspect the magnet ring (1) for clearance above the top of the steering column (2) and below the sensor (3). The distance between the magnet ring and the sensor should be equal to the distance between the magnet ring and the steering column. Adjust as necessary. The clearance between the steering column and the magnet ring (2) should be approximately 1.50 mm (0.06 in).

6. Ensure that the FNRP pod is seated correctly on the steering column. The tab on the FNRP pod should fit into the slot on the steering column. Adjust the FNRP pod as necessary.

RAIL13PLM0006AA

7. Tighten the bolt that secures the FNRP pod to the steering column. 8. Place the steering wheel back on the shaft while the FNRP pod is still disassembled. NOTE: Do not secure the steering wheel. 9. Re-assemble the FNRP pod and the mount the steering wheel on the shaft. 10. Test autoguidance functionality

Electrical systems - Autopilot/Autoguidance

Autoguidance sensors - Configure - Manual override sensor You can adjust the sensitivity of the autoguidance system if the steering wheel self-rotates while autoguidance is engaged. Prior operation: Check the clearance of the autoguidance manual override sensor: Autoguidance sensors - Clearance - Manual override sensor (55.680). NOTE: Perform this adjustment only if: • the steering wheel self-rotates when autoguidance is engaged, and • you have already checked the clearance of the manual override sensor (magnet ring). 1. Install the latest version of NAV II controller firmware (version 3.72 or above) using service tool 380002422. 2. Connect the Electronic Service Tool (EST) to the vehicle. 3. Click the EST icon to get the “Brand Selection” and “Equipment Selection” screens. 4. On the “Equipment Selection” screen, select “Intellisteer Auto Guidance System II/Precision Farming/GLOBAL POSITIONING SYSTEM (GPS).”

10. Enter the parameter “QORC” into the “Name” window. 11. Click the “Get” button. NOTE: The default value for this parameter is 2. The maximum value is 5. 12. Increase the value by 1. 13. Press the “Set” button to send the new value to the controller. 14. Test autoguidance performance in the field. • If the system no longer disengages without proper input, this completes the sensor configuration procedure. • If the system continues to disengage without proper input, repeat this procedure beginning with Step 2. If the maximum QORC value of 5 has already been reached, continue to Step 15. 15. Inspect the hand pump: • For binding in the steering column or binding at the pump-to-column connection • For internal leakage 16. Repair or replace the hand pump as required. 17. If the problem persists, copy the advanced configuration file and compress the .cn1 folder from the memory device into a .zip file and attach the .zip file to an ASIST concern. See Software - Download - Copy the .cn1 folder for submission to ASIST (55.785) and Software - Download - Copy the NAV II advanced configuration file for submission to ASIST (55.785).
