HYDRAULIC OIL SPECIFICATIONS

Table 11. Hydraulic Oil SAE Viscosity Grade Operating Temperature Ranges
Hydraulic System Operating Temperature Range
+0° to + 180° F (-18° to +83° C)
+0° to + 210° F (-18° to + 99° C)
+50° to + 210° F (+10° to + 99° C)
Note: Hydraulic oils require anti-wear qualities at least to API Service Classification GL-
3 and sufficient chemical stability for mobile hydraulic system service. JLG In-
dustries recommends standard UTTO.
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 viscosities. If use of hydraulic oil other than standard UTTO is de-
sired, contact JLG Industries for proper recommendations.
Note: Machine operation using non-JLG approved hydraulic fluids or operation out-
side of the temperature boundaries outlined in the hydraulic fluid operation
charts may result in premature wear or damage to components of the hydraulic
system.
Note: Machines may be equipped with standard UTTO biodegradable and non-toxic
hydraulic oil. This is a fully synthetic hydraulic oil that possesses the same anti-
wear and rust protection characteristics as mineral oils, but will not adversely af-
fect the ground water or the environment when spilled or leaked in small
amounts.
Note: When temperatures remain consistently below 20° F (-7° C), JLG Industries rec-
ommends the use of a premium "cold weather" hydraulic fluid (Viscosity Gr. 32).
