• Blockages: In certain conditions, particularly with wet or sticky materials, blockages can occur in the feed hopper or jaw cavity. These blockages can disrupt operation, requiring downtime to clear and reset the machine.
  
• Overheating: Prolonged use or inadequate cooling can cause the machine's engine or hydraulic components to overheat. Ensuring proper cooling systems are in place and regularly maintained is crucial to preventing such issues.
  

Maintenance and Care for the Terex Pegson AX866
Regular maintenance is essential to keep the Terex Pegson AX866 performing at its best. Proper maintenance not only extends the lifespan of the machine but also minimizes the risk of costly downtime or repairs. Here are some key maintenance tasks to consider:
1. Inspection of Jaw Plates
Jaw plates should be inspected regularly for wear and damage. Worn-out jaw plates can reduce the efficiency of the crusher and lead to uneven crushing. Replacing jaw plates at the appropriate intervals ensures the crusher operates optimally.

• Signs of Wear: Uneven wear, cracks, or chips on the plates are clear signs that replacement is needed.
  
• Replacement Frequency: The frequency of replacement depends on the material being crushed and the intensity of usage. Regular monitoring will help determine the right time for a change.
  

2. Hydraulic System Checks
The hydraulic system is vital for controlling jaw settings and ensuring smooth operation. Operators should regularly check for leaks, monitor hydraulic fluid levels, and inspect hoses and seals for wear.

• Fluid Levels: Low hydraulic fluid levels can cause erratic behavior and damage to the system. Ensure the fluid is topped up and at the proper viscosity.
  
• Leak Detection: Any visible leaks in the system should be repaired immediately to prevent further damage.
  

3. Cooling System Maintenance
Overheating can severely affect the performance of the AX866. Regular maintenance of the cooling system, including the engine and hydraulic cooling components, is necessary to avoid temperature-related issues.

• Radiator and Coolant: Ensure the radiator is clean and coolant levels are sufficient. Blockages in the cooling system can lead to overheating.
  
• Fan and Hoses: Check the cooling fan and hoses for any wear or damage. Replace them as needed to ensure proper airflow and cooling.
  

4. Regular Lubrication
Like all heavy equipment, the AX866 jaw crusher requires regular lubrication to reduce friction and wear on moving parts. Operators should follow the manufacturer’s lubrication schedule and use the recommended lubricants for optimal performance.

• Lubricating Points: Ensure that all moving parts, including bearings, pins, and other mechanical components, are adequately lubricated.
  
• Lubricant Quality: Using the wrong type of lubricant can lead to premature wear and system failure, so always adhere to manufacturer specifications.
  

Troubleshooting Common Issues
While the Terex Pegson AX866 is a reliable machine, certain issues may arise during operation. Here are some troubleshooting tips for common problems:
1. Slow Crushing or Reduced Output
If the machine is running slower than usual or not producing the desired output, it could be due to several factors:

• Blocked Feed Hopper: Ensure that the feed hopper is free from blockages.
  
• Worn Jaw Plates: Inspect the jaw plates for signs of wear or damage and replace if necessary.
  
• Clogged Hydraulic System: Check the hydraulic fluid levels and ensure the system is functioning correctly.
  

2. Excessive Vibrations
Vibrations during operation can indicate a misalignment or imbalance in the machine. Potential causes include:

• Loose Components: Check for loose bolts or parts that may be causing an imbalance.
  
• Worn Bearings: Inspect bearings for wear or damage and replace them if necessary.
  
• Damaged Jaw Plates: Ensure that the jaw plates are securely mounted and not cracked or worn unevenly.
