Lubrication
Hydraulic Oil (HO)
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, recommends Mobilfluid
424 hydraulic oil, which has an SAE viscosity of 10W-30 and a vis-
cosity index of 152.
For cold weather applications, i.e. when temperatures remain con-
sistently below +20°F (–7°C) JLG recommends using Mobil DTE
13 hydraulic oil.
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.
NOTE:
Refer to Lubrication Chart, Table 7-2 for specific lubrication
locations on machine.
