Genuine JLG Recommended Fluids
High-quality fluids for JLG scissor lifts, boom lifts, and telehandlers including DEF fluid, engine oil, hydraulic oil, and gear oil.
Hydraulic oil is the lifeblood of any construction machine, and the cleanliness of the oil is just as important as the proper amount. Dirty or contaminated hydraulic oil can damage internal components and void the manufacturer’s warranty. JLG recommendations for hydraulic oil cleanliness levels are based on the three-digit ISO code for 4 micron/6 micron/14 micron particle sizes found in 1 ml of fluid (reference ISO 4406:1999(E)). The acceptable level is 19/17/14 or below; anything higher requires system cleaning and filter replacement.
Always follow the JLG Service Manual for the appropriate maintenance intervals based on hours of operation. Equipment exposed to extremely dirty or hostile conditions may require more frequent service. Use only genuine JLG filters to assure necessary filtration requirements are met.
