[esh.01]

I recently purchased a 2018 bobcat s570 with 1300hrs. Machine sat in a yard for sometime and seems to operate well lots of power and no error codes. However the last time i used it i noticed a weird hissing/whistle noise when operating the machine i am new to heavy machinery and this is my first skid steer any help on where i should start to diagnose this would be greatly appreciated.

Sorry, I can not hear a hissing noise or any unusual noise for that matter from that video.
