1. Issue Overview
On the Panswork forum, a user reported issues with their Bobcat machine's hydraulic hammer. The user mentioned that the hydraulic hammer was working intermittently and its performance was affected. Since hydraulic hammers are commonly used in construction and demolition tasks, any performance issues can significantly impact efficiency and the lifespan of the equipment. Therefore, the user sought solutions for diagnosing and resolving the issue.
2. Common Causes of Failure
Issues with the Bobcat hydraulic hammer are typically related to insufficient hydraulic pressure, poor fluid quality, internal component failure, or loose connection parts. By checking and maintaining the hydraulic system pressure, oil quality, inspecting the hydraulic pump and pressure regulator, and ensuring the hammer's internal components and connections are in good condition, the hydraulic hammer’s performance can be restored.
Regular maintenance and inspection of the hydraulic system, ensuring clean and sufficient hydraulic fluid, and replacing worn components can significantly extend the hydraulic hammer’s lifespan. If the issue persists after troubleshooting, it is recommended to seek professional assistance for further diagnosis and repair.

2. Common Causes of Failure
- Insufficient Hydraulic System Pressure
- The hydraulic hammer relies on the normal pressure of the hydraulic system to operate. If the hydraulic pressure is too low, the hammer may work sluggishly or fail to activate. Insufficient hydraulic fluid, a malfunctioning hydraulic pump, or issues with the pressure regulator can all contribute to this problem.

- Poor Hydraulic Fluid Quality or Insufficient Fluid
- Hydraulic fluid is critical to the operation of the hydraulic system, and the quality and quantity of the fluid directly affect the hammer's performance. If the hydraulic fluid is of poor quality or there isn't enough fluid, it can cause increased friction within the system, affecting the hammer's efficiency.

- Internal Hammer Malfunctions
- Problems within the hydraulic hammer itself, such as damaged valves, pistons, or seals, can also be the root cause. These components may wear out or get damaged over time due to prolonged use or inadequate maintenance, leading to operational issues with the hammer.

- Loose or Worn Connection Parts
- If the connection between the hydraulic hammer and the Bobcat machine is loose or the parts are worn, it may hinder hydraulic fluid transfer, impacting the hammer’s performance. This includes issues with hydraulic lines and fittings that may cause leakage or pressure instability.

- Check the Hydraulic Oil System
- First, check the hydraulic system’s oil level and pressure. Ensure that the hydraulic fluid is at the proper level and that the fluid quality meets the required standards. If the oil is dirty or degraded, replace it with fresh hydraulic fluid. Make sure the oil type is suitable and that the fluid is clean.

- Inspect the Hydraulic Pump and Pressure Regulator
- Check the hydraulic pump and pressure regulator to ensure they are functioning properly. If the hydraulic pump is faulty, it may need to be repaired or replaced. If the pressure regulator is malfunctioning, it may require adjustment or replacement.

- Examine the Internal Components of the Hammer
- If the hydraulic system appears to be functioning well but the hydraulic hammer is still experiencing issues, it is advisable to disassemble the hammer and inspect internal components such as the valve, piston, and seals. Look for signs of wear, damage, or jamming. Replace any damaged parts as needed.
