The typical frequency for lubricating a hydraulic breaker is once every 2 hours of operation. However, in actual use, this should be adjusted according to specific working conditions and manufacturer requirements:
1. Normal working conditions: If the breaker is operating in a normal temperature, low-dust environment, lubrication can be performed every 2 hours. It is crucial to inject the grease while the chisel is pressed in; otherwise, the grease will rise into the impact chamber and enter the cylinder with the piston, causing hydraulic system contamination.
2. Harsh working conditions: High-temperature, high-dust, or high-intensity working environments, including continuous long-term operation, breaking hard or abrasive materials such as granite or reinforced concrete, operating in dusty, muddy, or high-temperature environments such as quarries and mines, or operating the hydraulic breaker at high impact frequencies. Why? These conditions accelerate grease deterioration and loss. Neglecting timely lubrication can lead to overheating, premature bushing wear, and even tool jamming or hydraulic breaker malfunction. It is recommended to shorten the lubrication interval to once every hour to ensure lubrication and reduce component wear.
3. Special Models or Manufacturer Requirements: Some hydraulic breaker models or manufacturers may have special requirements. For example, some large or high-performance hydraulic breakers may require more frequent lubrication or have specific requirements regarding the type and amount of grease to add. In this case, strictly follow the equipment manual or manufacturer’s instructions.
Note that when adding grease, use high-quality grease that meets the requirements (such as high-viscosity molybdenum disulfide extreme pressure lithium-based grease), and ensure that the filling tools and grease fittings are clean to prevent impurities from entering the breaker’s interior.
Daily Inspection of Automatic Lubrication System
If your hydraulic breaker is equipped with an automatic lubrication system, please inspect it daily. Confirm that the grease tank is full, grease lines and connections are unobstructed, the pump is operating normally, and the lubrication frequency setting matches your workload. Why?
Automatic lubrication systems can silently fail due to blockages, air locks, or mechanical malfunctions. Operating a hydraulic breaker without grease can lead to serious damage. Daily inspections help detect problems early and avoid costly downtime.
