Essential Maintenance Practices to Extend Your Hydraulic Hammer's Lifespan

A hydraulic hammer is a significant investment that, with diligent care, can deliver reliable performance for 8–10 years. Maximizing its lifespan depends heavily on consistent and proper maintenance during and between uses. Neglecting key operational steps can significantly shorten its service life. To help you ensure optimal function and safety, here are three essential tips for extending the durability and reliability of your hydraulic hammer.

1. Ensure Proper Carrier Setup and Flow Compatibility
The first and most critical step is to verify that the skid steer, mini-excavator, or excavator you are using is flow-tested before operation. This ensures the carrier supplies hydraulic oil within the hammer’s specified range. Exceeding the recommended flow can shorten the hammer’s life, while insufficient flow will reduce power output and compromise lubrication.

2. Follow Correct Operating Procedures
To prevent overheating and internal damage, avoid cycling the hammer in the same spot for more than 20 seconds. Prolonged localized use can melt demolition tools and damage internal components. Additionally, never “blank fire” the hammer—always ensure the tool is firmly pressed against the material before operation. Firing without contact places extreme stress on fasteners and retainers, often leading to broken tie rods and severe internal damage. Adhering to these practices helps maintain structural integrity and performance over time.

3. Use Specialized Lubricant and Maintain Regular Greasing
Standard chassis grease is not suitable for hydraulic hammers. Instead, use a dedicated chisel paste or hydraulic hammer lubricant with high metal content and a high melting point, designed to withstand intense metal-to-metal contact during operation. Applying 10–20 pumps of grease every two hours while the hammer is in a vertical position helps prevent bushing wear and reduces friction. Proper lubrication keeps the tool bushing area filled, which is essential for heat dissipation and smooth operation. Our experts can guide you on the appropriate type and quantity for your specific hammer model.

4. Store in a Vertical Position
Improper storage can lead to premature failure. Never store a hydraulic hammer horizontally, especially when hot, as this can deform seals and allow moisture intrusion. Over time, water entry can cause rust damage to the piston and cylinder. Always store the hammer vertically to preserve seal integrity and prevent internal corrosion.

5. Schedule Periodic Inspections and Maintenance
Like any complex machinery, hydraulic hammers require routine inspections. Check nitrogen levels regularly, and examine the hammer every forty hours of operation for missing, broken, or loose fasteners, as well as lower bushing wear. A single broken tie rod or side bolt can cause extensive internal damage if not detected early. Worn bushings may lead to piston scuffing and other failures. Scheduled professional maintenance helps identify and resolve issues before they compromise the hammer’s lifespan.

By integrating these practices into your equipment care routine, you can enhance safety, improve reliability, and significantly extend the service life of your hydraulic hammer.
