OPERATING THE MACHINE HYDRAULIC BREAKER AND HYDRAULIC CRUSHER Select a breaker or crusher that is the correct size and weight for your machine. See your authorized dealer for correct break- er information. Carefully study the operation manuals of the machine, breaker and crusher, and perform the required checks and/or inspec- tion before connecting the breaker or the crusher to the arm. IMPORTANT: Precautions for connecting breaker or crush- er piping. Do not allow impurities to enter into the system when switching the breaker or the crusher with the bucket.
When the breaker or crusher is not used, apply the cover to the pipe opening on the arm top and install the plug into the hose end of the breaker or the crush- er to prevent impurities from entering the system. Be sure to provide spare covers and plugs in the tool box so that they will be available when needed. After connecting, check the connecting seal fitting for oil leakage, and pipe clamp bolts for looseness. 5-18
