Case 680G Gearshift Operation Guide

[MikePhua]

The Case 680G is a widely used loader in construction and agricultural fields. For many operators, mastering the gear shifting of this machine is crucial, especially when working under heavy loads to ensure smooth operation and prevent mechanical damage. This article will help you understand how to properly operate the gearshift system on the Case 680G.
Understanding the Case 680G Transmission
The Case 680G is equipped with a manual or semi-automatic transmission, depending on the configuration. While the basic operation remains similar, understanding the transmission's working principles can help operators use the machine more effectively and avoid damaging the machinery.
The machine typically has forward, reverse, and neutral gears, along with a speed-shifting system that allows the operator to choose the appropriate gear for various tasks.
Basic Gearshift Operation Steps

1. Starting the Machine
   Ensure the machine is in neutral and press the clutch pedal. Before starting the engine, make sure the parking brake is fully engaged.
   
2. Shifting from Neutral to Forward Gear
   To start moving forward, depress the clutch pedal and shift the gear lever from neutral to forward gear. Gradually release the clutch and gently press the throttle to begin moving forward.
   
3. Shifting to Reverse Gear
   To move backward, first stop the machine and ensure it is stationary. Depress the clutch and shift the gear lever from forward gear to reverse. Slowly release the clutch and gently apply the throttle to reverse the machine.
   
4. Accelerating and Decelerating
   Adjust the throttle to control speed based on the task at hand. Maintain the appropriate gear to avoid excessive load on the machine while keeping the speed under control.
   

Important Tips

1. Avoid High-RPM Driving
   When the machine is under load or climbing a slope, avoid using high gears to accelerate forcefully. This could overload the transmission and cause damage.
   
2. Use the Correct Gear
   Choose the appropriate gear based on the task. Don't use low gears when high RPM is needed, nor should you use high gears on flat ground.
   
3. Smooth Gear Shifting
   Always press the clutch pedal smoothly during shifting, and avoid abrupt gear changes or quickly releasing the clutch. This will reduce wear on the transmission.
   
4. Regular Fluid Level and Oil Quality Checks
   The transmission fluid level and quality significantly affect the smoothness of gear shifting and the overall lifespan of the machine. Check the fluid level regularly and ensure the fluid is clean.
   

Conclusion
Proper operation of the Case 680G gearshift system is essential for the machine's long-term performance and the operator’s safety. By understanding the basic principles of gear shifting, following the correct procedures, and ensuring the machine remains well-maintained, you can maximize productivity and extend the life of your equipment. If you experience any gearshift problems, it is advisable to inspect and repair the machine promptly to ensure it remains in optimal working condition.
