Maintenance and Longevity
Maintaining a skid steer loader like the Gehl 7800 is crucial for ensuring its longevity and preventing costly repairs. Regular maintenance and inspection can help keep the machine in optimal condition, reduce downtime, and extend its lifespan. Here are some essential maintenance practices for the Gehl 7800:

1. Engine Maintenance: Regularly check the engine oil and coolant levels, and change the engine oil every 250 hours of operation or as recommended by the manufacturer. Keep the air filter clean and replace it when necessary to ensure proper airflow to the engine.
   
2. Hydraulic System: The hydraulic fluid should be checked regularly for contamination, and the fluid level should be maintained at the proper level. If the machine experiences slower-than-usual hydraulic function, it could be a sign of low fluid or a problem with the hydraulic filter, which should be replaced periodically.
   
3. Tire and Track Inspection: The 7800 comes with a set of durable tires or tracks, depending on the model. These should be inspected regularly for wear and tear. Proper tire inflation is essential for ensuring that the machine operates efficiently, while track tension should also be checked for optimal performance.
   
4. Greasing: All moving parts of the machine, including the boom, lift arms, and pivot points, should be regularly greased to reduce friction and prevent premature wear. This is an important step to ensure the longevity of the loader’s hydraulic components and overall performance.
   
5. Cooling System: Inspect the radiator and cooling system regularly to avoid overheating. Clean the radiator screen to remove debris and ensure proper airflow. Overheating can cause engine damage, so maintaining the cooling system is essential.
   
6. Fuel System: Regularly clean the fuel injectors and inspect the fuel lines for any signs of leaks or damage. Using the proper grade of fuel and keeping the fuel system clean will help maintain engine efficiency.
   

Common Issues and Troubleshooting
Though the Gehl 7800 is a reliable machine, like all heavy equipment, it can experience issues over time. Being aware of potential problems and knowing how to troubleshoot them can save time and money. Some common issues owners face with the Gehl 7800 include:

1. Hydraulic Problems: Slow or unresponsive hydraulics can be caused by low hydraulic fluid, a clogged filter, or a malfunctioning pump. Ensure that the fluid is at the correct level and that filters are replaced regularly. If problems persist, inspect the hydraulic pump for damage.
   
2. Engine Overheating: If the engine begins to overheat, it could be due to a clogged radiator, low coolant levels, or a malfunctioning thermostat. Always clean the radiator and check coolant levels to prevent overheating.
   
3. Electrical Issues: Electrical problems, such as starting issues or lights not working, are often caused by a weak battery, loose connections, or a faulty alternator. Ensure that the battery is charged and inspect all electrical components for wear and corrosion.
   
4. Reduced Power or Performance: If the machine starts to lose power or perform below expectations, it could be a result of clogged air filters, dirty fuel injectors, or issues with the fuel system. Regularly clean or replace air filters and fuel injectors to keep the machine running at peak performance.
