NOTE) Working Weight does not include bracket bushings and bracket pins.
Always operate the breaker with proper oil flow and working pressure shown above.
＊1) Cracking pressure means a pressure observed constant flow after the relief valve starts
opening by the pressure increased at the inlet port of the relief valve.
＊2) When the Breaker body temperature is 40℃（104F）.
