Proper hydraulic breaker/ rock hammer maintenance requires a sufficient supply of the correct grease to the tool (chisel). The hydraulic breaker tool must be pressed against a hard surface until it stops up inside the hammer. This prevents grease from entering hydraulic breaker piston impact area and ensures proper distribution of grease between the tool and tool bushings.

         Grease Your Hydraulic Hammer and Grease them Correctly
     Proper hydraulic breaker/hydraulic rock hammer maintenance requires a sufficient supply of the correct grease to the tool (chisel).  The hydraulic breaker tool must be pressed against a hard surface until it stops up inside the hammer.   This prevents grease from entering hydraulic breaker piston impact area and ensures proper distribution of grease between the tool and tool bushings.
Grease Intervals
     If the hammer is not connected to an autolube system, the hydraulic hammer must be greased at regular intervals to get the best life from the tool and tool bushing, there are two ways to determine grease intervals

     First, grease the hammer at the beginning of the job until grease comes out between the hydraulic hammer chisel and the lower tool bushing.  Run the hammer until the shank of the tool starts to look dry.  This determines the time interval for the greasing of this particular hammer on this particular job.   Typically, this is 1 to 4 hours.   Also, note the amount of grease needed to re-grease the tool.  This gives you the amount of grease and how often it must be applied.  An example would be that a particular hammer, on a particular job, requires half a tube of grease every 3 hours.  This would be the greasing schedule you would set up.  If this hammer was moved to another job, another grease schedule may have to be determined.

    Second, if you can’t control the grease schedule, such as hydraulic breaker rental units, then have the operator grease the hammer once every hour of hammer operation.  Again, grease the hammer until grease comes out between the tool and tool bushing.  This is usually more often than required, but is far cheaper than replacing prematurely worn tools and tool bushings.
