# Oil change intervals

Portable hydraulic equipment are susceptible to contamination due to the extreme conditions in which they work. Although selected fluids are designed to suffer less degradation than another product, we recommend an oil change and filter at least every 750 hours of use, or once a year, whichever occurs first.

It is recommended to periodically check the color of the oil and level seeking extreme contamination or loss of oil level that will require to refill the tank.

For oil changes or refilling, it is always recommended to use the same oil in the pump.

In case of an emergency and having to refill the tank and mix different types of fluids, it is preferred to use fluids with no additives as the HL or HLP fluids. After that, and always before a period of 2-4 working days, replace the oil with recommended oils.
