🔧What's Wrong with This Machine?
A wheel loader operator notices that the machine is taking longer than usual to raise its bucket. The loader still has enough power to drive around the jobsite, but the lift arms move noticeably slower than normal, especially when the machine is cold.
The operator also notices that the hydraulic system seems noisier than usual. After running the machine for a while, the hydraulic oil temperature begins to climb higher than it normally does.
