1.7 LUBRICATION
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 service. JLG Industries recom-
mends Mobilfluid 424 hydraulic oil, which has an SAE vis-
cosity index of 152.
NOTE: When temperatures remain consistently below 20 degrees
F. (-7 degrees C.), JLG Industries recommends the use of
Mobil DTE10.
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.
