NOTE:
Hydraulic oils require anti-wear qualities at least API Ser-
vice 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. They may not contain
required additives or be of comparable viscosities. If
hydraulic oil other than Mobil 424 is desired, contact JLG
Industries for proper recommendations.
