I have 2018 s70 only 300hrs for home use. this is what I noticed after using it here and there . is it air in the hydraulic fluid? should I be concern about it? it also make some noice when using the bucket lifting up and down. sometimes, the noice disappear at low rpm . it is come and go. I also noticed jerky movement while lifting bucket up with weight higher than 3-4 feet off the ground. any thought or advice? the machine runs fine otherwise.
