First verify if it is low hydraulic oil level warning or a filter restriction indicator. Cold oil is thicker and harder to flow through the system. Check for fine metal/debris in the hydraulic filter or oil indicating a pump or component failure occurring and if clean check for a faulty sensor or wiring in the hydraulic tank causing false alarms. If this is only when cold you may want to see if a lower viscosity oil that meets your machine spec would be better for your climate and outside temps. Try warming up the machine hydraulic tank using a torpedo space heater and then see once warm if the same symptoms exist or if it resolves. I am in the northeast and all equipment is sluggish in this cold weather and take a long time for hydraulics to heat up. One trick is once run for 20-30 minutes, put a function into a stall by deadheading the function to its stop and hold it there at a high rpm for several minutes at a time and this will bring the oil up to temp faster.
