What is the reason why the engine failure light of John Deere 9970 cotton picker is on

The sound of a big throttle speeding car appears when it is started.

John Deere Cotton Picker 7660 Troubleshooting: Hello dear! Glad for your question!

One of the reasons why the air conditioner of the 7006 cotton picker is not refrigerated: the freon is not enough (commonly known as the lack of fluorine) solution: The addition of freon can solve the problem of air conditioning not refrigerating, and most of the reasons for this non-refrigeration are mostly in the air conditioning that has been used for three or four years, and most of them are also a normal phenomenon, which belongs to the normal consumption of air conditioning refrigerant (that is, we often say freon or refrigerant) after long-term use, but this is only manifested as insufficient refrigeration of the air conditioner compared with the previous normal situation, and will not be completely uncooled, because the pressure is not enough, which is not too far from the normal value, in which case you just need to add it; Of course, there are also refrigerant leaks due to installation reasons or the machine itself, which is a common and relatively easy to find reason, and this kind of problem is relatively easy to deal with.

Use a pressure gauge to check the pressure after the beat, and if it is not enough, just add it. The second reason why the air conditioner is not cooling: the voltage of the power supply is not enough to solve the problem

Maintain a normal power supply voltage has encountered such a user, at home always said that the air conditioner is not cool enough, to check and found that it is normal, checked several times and did not find a problem. Later, an inspection finally found that the power supply voltage there was unstable and often could not reach the normal voltage, especially during the peak of electricity consumption. This problem manifests itself as:

When the voltage is normal, the air conditioner is also normal, and when the voltage is unstable, it will affect the air conditioner sometimes not to cool (the internal unit works, the compressor does not work). We have to start with the provision of a stable voltage. The third reason why the air conditioner does not refrigerate:

The power of the air conditioner is not enough to make the solution of no refrigeration: The power of the air conditioner needs to match the cooling capacity required by the space is also one of the reasons for a common non-refrigeration (poor refrigeration effect), but there are many reasons for this non-refrigeration, such as: small power air conditioning pipe large area of the room, and some although the air conditioning power and the room area seem to match, but because the room is relatively unsealed (such as doors and windows are wide open, etc.), or there is a heat source in the room (such as many computers) Of course, the west sun of the glass house is also one of the heat sources, and so on.

This kind of situation is easy for us to ignore, if we can find this as the cause and solve it well, it can not only make the air conditioner more basic and cooling, but also save electricity, and can also extend the service life of the air conditioner.

Hello, I'm glad to answer for you. You can adjust by adjusting the relative position of the adjusting plate and the round hole on the bracket to achieve the stove reputation, from rotating the adjusting plate until the spring just touches the hidden pressure plate, the front cotton picking head continues to rotate and adjust to 3 holes of the adjusting plate, and the rear cotton picking head is adjusted to 4 holes, aligned with the fixed holes on the bracket, insert the flange screw, and can also be adjusted to the front 4 and the rear 4. When adjusting, the pressure plate on the cotton picking head should be adjusted first, and the pressure plate of the virtual ear on the cotton picking head should be tightened only when necessary.

If the spring pressure is too small, there are fewer impurities in the picked cotton, but the residual cotton increases; If the pressure is too high, the net recovery rate will increase, but the cotton impurities will increase, and the wear of the machine parts will be increased.

Summary. Hello, I am glad to answer for you, the common fault code of John Deere cotton machine 7760 is, E001: The battery voltage is too low; e002:

The battery voltage is too high; E003: Engine oil pressure is too low; E004: Engine Oil Temperature Is Too High; e005:

The hydraulic oil temperature is too high; E006: Hydraulic oil pressure is too low; E007: Air Filter Blocked; e008:

Blocked hydraulic oil filter; E009: Oil-water separator is clogged; E010: Air Cleaner Sensor Fault; e011:

Hydraulic oil filter sensor failure; E012: Oil-water separator sensor fault. <>

Dear, can you provide specific information about your John Deere 7760 fault code? <>

Coolant circuit failure.

Hello, I am glad to answer for you, the common fault code of John Deere cotton machine 7760 is, E001: The battery voltage is too low; E002: Battery voltage is too high; e003:

The engine oil pressure is too low; E004: Engine Oil Temperature Is Too High; E005: Hydraulic oil imitation cherry blossom temperature is too high; e006:

The hydraulic oil pressure is too low; E007: Air Filter Plex Cleaner Blocked; E008: Hydraulic Oil Filter Clogging; e009:

Oil-water separator blockage; E010: Air Cleaner Sensor Fault; E011: Hydraulic Oil Filter Sensor Failure; e012:

Oil-water separator sensor malfunction. <>

Dear, the fault code of the coolant circuit is that the fault code indicates that the oil-water separator is blocked, which is caused by sediment or impurities in the coolant circuit. It is recommended that you inspect the coolant circuit, remove any sediment or impurities, and replace the water separator. <>

Is there a solution to the water tank when it is always gasy.

Dear, the solution to the problem of the water tank is always angry, 1Check if the pump impeller is damaged or badly worn, and if so, the pump needs to be replaced. 2.

Check that the tank lid is well sealed, if not, you will need to replace the tank cover or replace the gasket. 3.Check the cold cavity excavation system for vulnerabilities, and if so, fix the holes and refill the coolant.

4.Check the cooling system for the presence of air, and if so, the cooling system exhaust operation needs to be carefully checked. <>
