Hydraulic Oil
NOTE: Hydraulic oils require anti-wear qualities at least API Service
Classification GL-3, and sufficient chemical stability for mobile
hydraulic system service.
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. If use of
hydraulic oil other than Mobil 424 is desired, contact JLG Indus-
tries for proper recommendations.
