Before operating a hydraulic breaker hammer, it’s important to understand its main components and ensure compatibility with your carrier machine, whether it’s an excavator, digger, or skid steer. The main parts of a hydraulic rock hammer for excavators include:

• Hydraulic Breaker Chisel / Tool: The working end that strikes and breaks the material.
• Piston: Delivers powerful impact force.
• Hydraulic Cylinder: Drives the piston using pressurized hydraulic fluid.
• Valve System: Controls the hydraulic fluid flow and impact cycle.

Compatibility Checklist:

• Oil flow rate (L/min) matches the hydraulic breaker hammer’s requirements.
• Operating pressure is within the recommended range.
• Carrier weight class (excavator, digger, or skid steer) is suitable for the hydraulic rock hammer.
• Mounting brackets and pin sizes fit securely for your excavator breaker hammer or skid steer breaker.

Proper compatibility ensures optimal performance and helps avoid premature wear or damage.

A thorough pre-operation inspection is critical for any hydraulic breaker for skid steers, excavators, or diggers. Follow these steps to ensure your rock hammer is ready for safe, efficient use:

1. Oil Inspection:
   - Check hydraulic oil level and quality.
   - Replace hydraulic oil after the first 250 hours, then every 1,500 hours.
2. Chisel Clearance:
   - Inspect the hydraulic breaker chisel for wear and clearance before operation.
3. Stop Valve Check:
   - Make sure the stop valve is fully open during operation.
4. Bolt and Fastener Check:
   - Tighten all bolts, screws, and oil hoses evenly and diagonally. This is crucial for both digger hydraulic breakers and hydraulic rock hammers.
5. Bush and Lubrication:
   - Inspect the chisel bush and thrust bush for wear.
   - Grease bushings every two working hours, and always lubricate with the rock hammer pressed firmly in a working position.
6. Warm-Up Procedure:
   - Run the breaker at low load and low pressure until the hydraulic oil temperature reaches about 50°C.

Neglecting these checks can compromise the performance of your excavator breaker hammer and lead to expensive repairs.

Operating your hydraulic breaker hammer correctly is essential for maximizing efficiency and protecting your investment. Here are the top guidelines for daily operation:

• Avoid Operating at Cylinder Limit:
  Maintain at least a 10 cm clearance between the breaker and the excavator arm at full extension to prevent structural damage.
• Prohibit Blank Firing:
  Stop immediately if blank firing (striking without resistance) occurs. This can cause serious internal damage to your hydraulic breaker.
• Ensure Perpendicular Strikes:
  Always position the hydraulic breaker chisel perpendicular to the material. Angled impacts cause premature chisel wear or breakage and may damage the excavator breaker hammer housing.
• Do Not Strike in One Spot Continuously:
  If the material does not fracture within 30–60 seconds, reposition the chisel. Prolonged impact can overheat hydraulic oil and damage internal seals.
• Avoid Misuse (No Prying, Sweeping, or Pushing):
  Don’t use the hydraulic rock hammer to pry, sweep debris, or push materials. This can damage the chisel, housing, and excavator arm.
• Do Not Use for Lifting or Carrying:
  Never use the breaker to lift or carry heavy objects with your digger or skid steer. This can deform the chassis or mounting bracket.
• No Underwater Operation (Unless Properly Modified):
  Standard hydraulic breakers are not designed for underwater use. Special modifications are required for underwater applications.

Proper maintenance after every job can dramatically extend the life of your hydraulic breaker hammer and ensure consistent performance:

1. Clean the Breaker:
   - Remove dust and debris from the hydraulic breaker chisel, tool, and housing.
2. Inspect the Chisel:
   - Check for cracks, deformation, or excessive wear. Replace if necessary.
3. Check for Loose Bolts/Fittings:
   - Tighten any bolts, side bolts, or hydraulic fittings that may have loosened during operation.
4. Lubricate Moving Parts:
   - Apply grease to the chisel and bushings or ensure the automatic lubrication system is functioning.
5. Record Operating Hours:
   - Keep a log of daily use to plan timely maintenance and inspections.

Always refer to your model’s maintenance manual for specific guidelines.

Hydraulic breaker hammers, whether for excavators, diggers, or skid steers, are powerful and require strict adherence to safety protocols:

• Wear Personal Protective Equipment (PPE):
  Use a hard hat, safety goggles, gloves, steel-toed boots, and hearing protection.
• Control Bystander Access:
  Ensure only trained and authorized personnel are in the operating area.
• Never Use as a Lifting Device:
  Only use the hydraulic breaker hammer for its intended purpose.
• Operate on Stable Surfaces:
  Stabilize the carrier (excavator, digger, or skid steer) before operation.
• Train All Operators:
  Provide comprehensive training on safe operation, maintenance, and emergency procedures.

Efficient, safe operation of a hydraulic breaker hammer—whether a hydraulic rock hammer for excavators, a digger hydraulic breaker, or a hydraulic breaker for skid steers—requires proper equipment matching, thorough pre-operation inspection, correct handling, and regular maintenance. By following these guidelines from Jiangsuguchuan, you will:

• Extend the service life of your hydraulic breaker hammer
• Reduce unplanned downtime and repair costs
• Improve worksite safety and overall productivity
