The Preventive Maintenance Checklist Every Hydraulic Breaker Owner Should Follow

Hydraulic breakers are the muscle behind many construction, demolition, and mining projects. But like any hardworking piece of equipment, they need proper care to keep delivering maximum power, efficiency, and reliability. Neglecting maintenance not only shortens a breaker’s lifespan but can also lead to costly downtime and expensive repairs.

Whether you run a single unit or manage a fleet, this preventive maintenance checklist will help you keep your breaker in peak condition.

1. Daily Inspections Before Operation

A quick daily check can catch small issues before they become major problems.

• Check for leaks in hoses, fittings, and connections.
  
  

• Inspect tool (chisel, moil, blunt) for wear or cracks.
  
  

• Ensure retaining pins and bushings are secure and not excessively worn.
  
  

• Listen for abnormal sounds during operation — grinding, rattling, or hissing can be early warning signs.
  
  

💡 Tip: Always perform inspections with the breaker off and depressurized.

2. Monitor Hydraulic Oil Quality and Level

The breaker’s lifeblood is hydraulic oil. Contaminated or insufficient oil can destroy internal components.

• Maintain correct oil viscosity based on your machine and ambient temperature.
  
  

• Check for signs of contamination (milky appearance = water, dark oil = overheating).
  
  

• Replace oil and filters according to the manufacturer’s schedule.
  
  

3. Grease — and Then Grease Again

Lubrication is critical for reducing wear between the breaker’s tool and bushing.

• Apply high-quality chisel paste before starting work and every 1–2 hours during operation.
  
  

• Focus on the lower bushing — dry running here is a common cause of premature wear.
  
  

• Avoid over-greasing, which can attract dust and cause buildup.
  
  

4. Check Nitrogen Pressure Regularly

Most breakers use nitrogen in the back head to assist impact force.

• Test pressure monthly or according to manufacturer’s recommendation.
  
  

• Low pressure reduces power; excessive pressure increases stress on components.
  
  

• Always use the correct gauge and follow safety protocols.
  
  

5. Inspect Mounting Hardware

Loose or damaged mounting bolts can cause misalignment and frame damage.

• Tighten bolts to specified torque values.
  
  

• Look for cracks or deformation on mounting brackets.
  
  

• Ensure the breaker is securely attached to the carrier.
  
  

6. Replace Worn Parts Before Failure

Waiting until a part breaks can cause secondary damage.

• Monitor bushings, tool retainers, and wear plates for limits set in your breaker’s manual.
  
  

• Keep a small inventory of common wear parts to minimize downtime.
  
  

7. Follow Seasonal Maintenance Adjustments

Your breaker’s needs change with the environment.

• Cold weather: Use low-viscosity hydraulic oil, warm up before heavy work.
  
  

• Hot weather: Check cooling system efficiency, monitor oil temperature closely.
  
  

• Dusty conditions: Increase greasing frequency and air filter maintenance.
  
  

8. Keep Service Records

Documenting maintenance helps track performance, warranty compliance, and resale value.

• Log all inspections, pressure checks, part replacements, and oil changes.
  
  

• Use a simple spreadsheet or maintenance management app.
