I have a LX 665 with 2500 hours. The arms and bucket have almost no power until the hyd oil gets above 38⁰F. Any suggestions? After the oil gets warm, it works great.
 
What oil is in it? Oil condition? Milky? Hydraulic filter age? Just the first questions that come to mind.
 
yeah that makes me think the oil is to thick for your temps now. that is if the oil is in good shape ,no water.filter not restricted.
 
I'd start there. 10w30 is call for. And I can tell you that 15w40 will not work right.
