Hydraulic Oil
NOTE:
Hydraulic oils must have anti-wear qualities at least to API Ser
-
vice Classification GL-3, and sufficient chemical stability for
mobile hydraulic system service. JLG Industries recommends
standard UTTO, which has an SAE viscosity index of 152.
NOTE:
When temperatures remain below 20° F (-7 degrees C), JLG
Industries recommends the use of Mobil DTE 10.
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.
