How to Maintain Your Hydraulic Breaker: A Complete Guide to Extend Its Lifespan

A hydraulic breaker (also known as a hammer) is a powerful attachment used in construction, demolition, and mining. Proper maintenance is crucial to ensure maximum performance, longevity, and safety. Neglecting maintenance can lead to costly repairs, downtime, and reduced efficiency.

This guide covers essential maintenance tips, common issues, and best practices to keep your hydraulic breaker in top condition.

Why Hydraulic Breaker Maintenance Matters

• Prevents premature wear – Reduces damage to internal components.

• Improves efficiency – Ensures consistent breaking power.

• Saves money – Avoids expensive repairs and replacements.

• Enhances safety – Reduces the risk of sudden failures.

Daily Maintenance Checklist

1. Lubrication (Most Critical Step)

• Use high-quality grease (preferably lithium-based with EP additives).

• Grease every 2 hours of operation or as per manufacturer’s guidelines.

• Apply grease until it purges from the tool bushing (prevents dust ingress).

2. Check Hydraulic Fluid & Filters

• Monitor oil levels – Low fluid causes overheating and damage.

• Change filters regularly – Clogged filters reduce hydraulic efficiency.

• Use the correct oil (ISO VG46 or VG68, depending on climate).

3. Inspect for Leaks & Damage

• Check hoses and connections for cracks or leaks.

• Look for loose bolts – Tighten them to the manufacturer’s torque specs.

• Examine the tool (chisel/moil point) – Replace if worn or cracked.

Weekly & Monthly Maintenance

1. Clean the Breaker

• Remove dirt, debris, and built-up material around the piston area.

• Use compressed air or a brush (never water, as it causes rust).

2. Check Nitrogen Pressure (If Applicable)

• Most breakers have a nitrogen gas chamber for shock absorption.

• Maintain proper pressure (varies by model, usually 14-16 bar).

3. Inspect Bushings & Seals

• Worn bushings cause misalignment and reduce efficiency.

• Replace damaged seals to prevent oil leaks.

Common Problems & Solutions

Long-Term Maintenance Tips

1. Store Properly When Not in Use

• Keep in a dry, covered area to prevent rust.

• Release hydraulic pressure before storage.

2. Avoid Dry Firing (Running Without Contact)

• Causes piston and seal damage – Always operate against material.

3. Follow Manufacturer’s Service Intervals

• Replace wear parts (bushings, seals) as recommended.

• Professional inspection every 500 hours.

Conclusion: Maximize Your Breaker’s Lifespan

By following these maintenance steps, your hydraulic breaker will:
✅ Last longer (up to 50% extended lifespan)
✅ Perform better (consistent breaking power)
✅ Save repair costs (fewer breakdowns)
