1.7 LUBRICATION
Hydraulic Oil
NOTE: Hydraulic oils must have anti-wear qualities at least to
API Service Classification GL-3, and sufficient chemi-
cal stability for mobile hydraulic system service. JLG
Industries recommends Mobilfluid 424 hydraulic oil,
which has an SAE viscosity index of 152.
NOTE: When temperatures remain consistently below 20°F (-7°C),
JLG Industries recommends using Mobil DTE13.
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 Mobilfluid 424 is desired,
contact JLG Industries for proper recommendations.
