The Koering 6644LEX is a versatile and powerful skid steer loader, popular for its ability to handle heavy-duty tasks in tough environments. However, like all complex machinery, it can experience occasional issues, especially with its joystick control system. Joysticks are the primary interface for controlling the machine's movement, and any malfunction can greatly impact the operator's ability to control the equipment effectively.
This article will explore common joystick issues found in the Koering 6644LEX, offer troubleshooting tips, and discuss potential solutions to keep the machine running smoothly.
Understanding the Joystick Control System
The joystick on a skid steer like the Koering 6644LEX controls both the movement and operation of the loader. It is typically used for steering, lifting, tilting, and operating auxiliary hydraulics. Given its critical role, any malfunction in the joystick can make the loader difficult or even unsafe to operate.
The joystick system consists of:
Several issues can arise with the joystick system on the Koering 6644LEX. These problems can lead to jerky movements, unresponsiveness, or full mechanical failure. Below are some common joystick-related issues:
1. Unresponsive Joystick Movement
One of the most common problems reported with the Koering 6644LEX joystick is a lack of response. This might manifest as the joystick not moving the loader, or it might result in jerky movements that are difficult to control.
Another common problem is when the joystick moves the loader in a jerky, uncoordinated manner or with a significant delay. This problem can make precise movements, such as loading or lifting materials, challenging and unsafe.
A joystick that sticks or binds during use can be frustrating, especially in tight workspaces where precise movements are crucial.
When the joystick is used for steering, inconsistent or unpredictable steering behavior can be a major issue. The loader may drift to one side or fail to respond accurately to steering inputs.

Understanding the Joystick Control System
The joystick on a skid steer like the Koering 6644LEX controls both the movement and operation of the loader. It is typically used for steering, lifting, tilting, and operating auxiliary hydraulics. Given its critical role, any malfunction in the joystick can make the loader difficult or even unsafe to operate.
The joystick system consists of:
- Mechanical components: These components convert the physical movement of the joystick into electrical signals that the loader's hydraulic and electrical systems interpret.
- Electrical connections: Joysticks on modern machines often come with integrated sensors, which transmit signals via wires to the main control system.
- Hydraulic feedback: For some systems, the joystick also controls hydraulic flow to various components, meaning the feedback from the joystick can impact the load and steering functionality.
Several issues can arise with the joystick system on the Koering 6644LEX. These problems can lead to jerky movements, unresponsiveness, or full mechanical failure. Below are some common joystick-related issues:
1. Unresponsive Joystick Movement
One of the most common problems reported with the Koering 6644LEX joystick is a lack of response. This might manifest as the joystick not moving the loader, or it might result in jerky movements that are difficult to control.
- Potential Causes:
- Faulty joystick sensor: Over time, the sensors that detect joystick movement may become worn out or damaged.
- Wiring issues: If the electrical connections are loose or damaged, they can prevent the joystick from transmitting signals properly.
- Hydraulic issues: A malfunction in the hydraulic system that affects joystick-controlled movements can also cause the machine to behave erratically.
- Faulty joystick sensor: Over time, the sensors that detect joystick movement may become worn out or damaged.
Another common problem is when the joystick moves the loader in a jerky, uncoordinated manner or with a significant delay. This problem can make precise movements, such as loading or lifting materials, challenging and unsafe.
- Potential Causes:
- Dirty or worn-out potentiometer: The potentiometer is responsible for measuring the angle and direction of the joystick movement. If it gets dirty or worn, it can send incorrect readings, resulting in erratic control.
- Low hydraulic fluid levels: Insufficient hydraulic fluid can cause delays or jerks when operating the machine’s movements, including the joystick-controlled features.
- Electronic control malfunction: The joystick system might have an issue in its controller, such as faulty wiring or software problems, leading to delayed responses.
- Dirty or worn-out potentiometer: The potentiometer is responsible for measuring the angle and direction of the joystick movement. If it gets dirty or worn, it can send incorrect readings, resulting in erratic control.
A joystick that sticks or binds during use can be frustrating, especially in tight workspaces where precise movements are crucial.
- Potential Causes:
- Lack of lubrication: Joysticks rely on smooth mechanical movement to operate properly. Without sufficient lubrication, the moving parts can become stuck or resist movement.
- Mechanical wear: Over time, the mechanical components inside the joystick can wear out, causing the joystick to bind or feel sluggish.
- Lack of lubrication: Joysticks rely on smooth mechanical movement to operate properly. Without sufficient lubrication, the moving parts can become stuck or resist movement.
When the joystick is used for steering, inconsistent or unpredictable steering behavior can be a major issue. The loader may drift to one side or fail to respond accurately to steering inputs.
- Potential Causes:
- Steering linkage issues: The hydraulic steering mechanism may be misaligned or have air trapped in the system.
- Control system malfunction: The joystick might not be properly calibrated with the loader’s control system, leading to erratic steering behavior.
- Hydraulic fluid contamination: Contaminants in the hydraulic fluid can cause poor performance, especially in the steering components.
- Steering linkage issues: The hydraulic steering mechanism may be misaligned or have air trapped in the system.
If you are experiencing joystick problems with your Koering 6644LEX, follow this troubleshooting guide to help identify and resolve the issue.
1. Check the Joystick for Physical Damage
- Inspect the joystick for any visible cracks or damage that could be affecting its movement. If the joystick has been physically damaged, it may need to be replaced.
- Loose or corroded wiring: Examine all electrical connections, including those on the joystick and its control system, for signs of wear, corrosion, or loose wiring.
- Testing electrical signals: Use a multimeter to test if the joystick is properly transmitting signals to the control system. A failure to transmit signals can indicate a wiring or sensor issue.
- Verify the hydraulic fluid level in the system. Low levels can cause jerky movements or unresponsiveness from the joystick-controlled actions. If necessary, top off the hydraulic fluid, ensuring you use the correct type specified in the owner's manual.
- If the joystick is jerky or unresponsive, check the potentiometer for dirt or wear. Clean it carefully or replace it if it's damaged.
- If the joystick’s steering or lifting response is erratic, it may need recalibration. Consult the machine’s manual for the specific procedure for recalibrating the joystick.
- In some cases, joystick issues may be related to the software in the loader’s electronic control system. Ensure the control system firmware is up to date.
- If you’re unable to identify or fix the issue through the steps above, it may be time to contact a technician or service center. Some joystick problems, especially those related to the hydraulic or electrical systems, may require professional diagnosis.
To prevent joystick issues from recurring, it’s important to follow a few key maintenance practices:
- Regular Lubrication: Periodically lubricate the joystick mechanism to prevent binding and wear.
- Routine System Checks: Check hydraulic fluid levels, electrical wiring, and system components regularly.
- Keep the Potentiometer Clean: Prevent dirt and grime from building up on the potentiometer by regularly cleaning it during maintenance.
The joystick on a Koering 6644LEX is essential for the loader’s operation, controlling both its movements and hydraulic actions. While joystick issues can be frustrating, understanding the common problems and following the troubleshooting steps can help operators address these issues quickly and effectively.
