+50° to + 210° F (+10° to +99° C
NOTE: Hydraulic oils must have anti-wear qualities at least to API
Service Classification GL-3, and sufficient chemical stability
for mobile hydraulic system service. JLG Ind. recommends
Standard UTTO fluid, which has an SAE viscosity index of
152.
NOTE: When temperatures remain consistently below 20° F
(-7° C), JLG Industries recommends the use of Premium
Hydraulic Fluid.
NOTE: Machines may be equipped with Mobil EAL224H biode-
gradable and non-toxic hydraulic oil. This is Vegetable oil
based and possesses the same antiwear and rust protec-
tion characteristics as mineral oils, but will not adversely
affect the ground water or the environment when spilled or
leaked in small amounts. Mobil EAL-224H has a viscosity of
34 cSt at 40° C. and viscosity index of 213. The operating
temperature range of this oil is -18° C to +83° C.
NOTE: Aside from JLG recommendations, it is not advisable to mix
oils of different brands or types, as they may not contain
the same required additives or be of comparable viscosi-
ties. If use of hydraulic oil other than Standard UTTO is
desired refer Figure 2-3., Hydraulic Oil Operating Tempera-
ture Specifications.
