FOUR QUICK STEPS TOWARD INCREASED UPTIME
he hydraulic breaker attachment (one of the most common attachments for a remote-controlled demolition machine) generates as much as 1,500 foot-pounds of force at its tip. Typical wear and tear is expected, which is why keeping up on breaker maintenance is vital to ensure optimum performance on the jobsite. “Operators often overlook breakers, so they might not receive the proper time and attention they deserve in a maintenance regiment,” said Keith Becker, managing member of Becker Equipment. “To get the most out of their investment, operators should consider the breaker as another piece of equipment with its own service schedule rather than a simple attachment, such as a bucket scoop.
While the breaker requires the machine’s hydraulic system to provide the pressure to run, it is just as important as the machine itself and requires regular servicing.” Ready to begin servicing, but not sure where to begin? It is simple. Take the time to follow these four steps and you will be on your way to increased uptime and maximum breaker life.

Step one: choose the right grease
Not all grease is the same. Look for a chisel paste that can withstand temperatures as high as 235°C. Keep in mind, if grease is running down the tool, it is most likely not correct. Proper greasing minimizes metal-
on-metal contact to prevent the tool from overheating, which can prematurely wear tool steel, damage bushings, and ruin hydraulic seals. Using standard grease may save you nickels and dimes now but could eventually cost you time and money by requiring more frequent greasing. And if the tool steel is not properly lubricated, you will see added costs in tool steel replacements. Some companies offer a durable, molybdenum-based chisel paste. This paste contains small copper and graphite particles that roll up like ball bearings between the tool steel and working bushing. The paste is also more viscous than standard lubricants, which allows it to CONTINUED ON PAGE 24
