Hydraulic Oil
NOTE: Hydraulic oils must have anti-wear qualities at least
to API Service Classification GL-3, and sufficient
chemical stability for mobile hydraulic system ser-
vice. JLG Ind. recommends Mobilfluid 424 hydraulic
oil, which has an SAE viscosity index of 152.
NOTE: When temperatures remain consistently below 20
degrees F. (-7 degrees C.), JLG Industries recom-
mends the use of Mobil DTE-13.
NOTE: Machines may be equipped with Mobil EAL224H bio-
degradable and non-toxic hydraulic oil. This is Vege-
table oil based and possesses the same anti-wear
and rust protection characteristics as mineral oils,
but will not adversely affect the ground water or the
environment when spilled or leaked in small
amounts. Mobil EAL224H has a viscosity of 34 cSt at
40° C. and viscosity index of 213. The operating tem-
perature range of this oil is -18° C. to +83° C.
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.
