Introduction
Hydraulic hammers are powerful attachments used for demolition, excavation, and breaking operations in construction and mining. This comprehensive operational checklist ensures proper setup, safe operation, and effective performance monitoring of hydraulic hammers. Regular inspection using this checklist helps prevent equipment damage, extend service life, and maintain a safe working environment.
Whether you're operating a small breaker on a skid steer or a large hydraulic hammer on an excavator, this checklist covers critical inspection points including power unit compatibility, mounting hardware, hydraulic system integrity, lubrication requirements, and operational checks. Following this checklist helps maintain compliance with manufacturer specifications and OSHA safety standards while maximizing productivity and minimizing downtime.
Equipment Information
Pro Tips for Effective Hydraulic Hammer Operation
- Continuous Operation: Avoid operating the hammer continuously for more than 15-30 seconds in one spot. Move to a different location to prevent overheating and ineffective hammering.
- Proper Positioning: Always position the tool perpendicular (90°) to the work surface for optimal energy transfer and to prevent damage to the tool and housing.
- Greasing Intervals: Most hydraulic hammers require greasing every 2 hours of operation. Check manufacturer specifications for your specific model.
- Blank Firing Prevention: Never operate the hammer without resistance (blank firing). This can cause severe internal damage to the hammer components.

Operational Procedures
Follow these structured procedures to ensure safe and effective operation of your hydraulic hammer. These guidelines help maximize productivity while minimizing equipment damage and safety hazards.
Startup Procedure
- Ensure carrier is stable on level ground
- Allow carrier hydraulic oil to reach operating temperature
- Position hammer at work area without contacting surface
- Activate hammer briefly to ensure proper operation
- Apply tool to work surface before continuous operation
Proper Breaking Technique
- Position tool perpendicular (90°) to work surface
- Apply sufficient down pressure (but not excessive)
- Break material in manageable sections (15-30cm spacing)
- Work from edges or existing cracks when possible
- Avoid continuous operation for more than 30 seconds in one spot
Monitoring During Operation
- Watch for abnormal tool movement or bounce
- Listen for changes in hammer sound/rhythm
- Monitor for hydraulic leaks or hose movement
- Check carrier hydraulic oil temperature periodically
- Ensure proper penetration/breaking performance
Shutdown Procedure
- Remove tool from work surface before stopping
- Deactivate hammer and relieve hydraulic pressure
- Lower hammer to ground or rest position
- Inspect for damage, leaks, or overheating
- Clean tool and lubricate if continuing next shift
Troubleshooting Common Issues
Reference this guide to quickly identify and address common hydraulic hammer operational problems. Early intervention can prevent more serious damage and downtime.
Hammer Not Operating
- Check hydraulic connections and verify proper hookup
- Verify carrier auxiliary hydraulic activation
- Check for hydraulic flow and pressure
- Inspect for jammed or seized piston/tool
- Check accumulator nitrogen pressure (if equipped)
Low Impact Performance
- Verify carrier is providing proper flow and pressure
- Check for worn tool or bushings
- Inspect for internal leakage or seal damage
- Verify accumulator nitrogen pressure
- Check for proper down pressure application
Erratic Operation
- Check for air in hydraulic system
- Verify consistent hydraulic flow
- Inspect for damaged or worn internal components
- Check valve operation and control circuit
- Ensure proper lubrication of all components
Excessive Heating
- Check for hydraulic flow restrictions
- Verify hydraulic oil cooler is functioning
- Avoid prolonged continuous operation
- Check for internal leakage or bypass
- Ensure hydraulic oil is proper viscosity and level
