what are the small hydraulic lines on a mini excavator used for?

[Rebeldad1]

I have a E26C mini excavator. Along with the two lines on the boom for the thumb I have 2 smaller (about 1/2 the diameter) lines at the end of the boom. What are these for or... what can I use these for?
Thanks in advance

They are for hooking up a breaker attachment I believe.
