How do you check hydraulic oil level?
Check the hydraulic fluid level by looking at the sight glass on the side of the hydraulic tank (a Geoprobe® Model 54LT is shown), or on some units, by checking the dipstick on the hydraulic cap. Check your Owner’s Manual for the correct fluid levels.
Does hydraulic oil expand when hot?
Thermal expansion of hydraulic oils The volume of a specific hydraulic oil not only changes due to pressure changes, but also due to changes in temperature. When the temperature increases, the density of the oil decreases, leading to an increase in volume.
Why do hydraulics overheat?
Why Do Hydraulic Systems Overheat? Heating of hydraulic fluid in operation is caused by inefficiencies. Inefficiencies result in losses of input power, which are converted to heat. If the total input power lost to heat is greater than the heat dissipated, the hydraulic system will eventually overheat.

Do you check hydraulic oil hot or cold?
