E xcavator-mounted hydraulic breakers are an ideal attachment to help break rock, concrete, asphalt and other construction and aggregate materials. However, to achieve long-lasting attach- ment performance, routine maintenance needs to be top of mind. A lack of routine maintenance can easily derail production, costing you valuable time, money, and potentially decreasing the attachment's lifes- pan. By following these six tips, you can get optimal performance and life out of your heavy-duty hydraulic breaker. Tip No. 1: Complete a visual inspection Although it only takes a few minutes to visually inspect a hydraulic breaker for wear and tear, many operators overlook this step. A visual inspection should be completed each time the breaker will be used to help identify any worn or damaged components and prevent unexpected downtime. "Daily visual checks can give an early look at worn items that can lead to potential failures down the road," says Lee Smith, Doosan attach- ment product specialist. "Check hydraulic hoses, the breaker shell, attach- ment pins, tool retainers and locks; and the tool point, for any cracks or gouges." Tip No. 2: Use the correct maintenance tools Many breaker manufacturers provide a specialized check tool to measure the breaker's lower bushing, top angle of the breaker tool, and retaining pins. "Using this maintenance tool for its recommended checks will de- crease the likelihood of early component failure," Smith says. The fi rst step to using the maintenance tool is removing the retainer pins and breaker tool. Once the breaker tool is removed, it is a good AGGREGATES MANAGER / August 2017 23 For a long life in a harsh operating environment, be sure to take proper care of your hydraulic breaker.
