Lubrication
Hydraulic Oil
NOTE: Hydraulic oils must have anti-wear qualities at least to API
Service Classification GL-3, and sufficient chemical stabil-
ity for mobile hydraulic system service. JLG Industries rec-
ommends Mobilfluid 424 hydraulic oil, which has an SAE
viscosity index of 152.
NOTE: When temperatures remain below 20° F (-7° C), JLG Indus-
tries recommends the use of Mobil DTE13.
NOTE: Aside from JLG recommendations, it is not advisable to
mix oils of different brands or types, as they may not con-
tain the same required additives or be of comparable vis-
cosities. If use of hydraulic oil other than Mobilfluid 424 is
desired, contact JLG Industries for proper recommenda-
tions.
