1.5 TORQUE REQUIREMENTS
* Check swing bearing bolts for security after first 50
hours of operation and every 600 hours thereafter.
1.6 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 ser-
vice. JLG Industries 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 DTE11.
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.
