OPERATING TEMPERATURE
RANGE
+0° to +180° F (-18° C to +83° C)
+0° F to +210° F (-18° C to +99° C)
+50° F to +210° F (+10° C to +210° C)
NOTE: Hydraulic oils must have anti-wear qualities at least to API
Service Classification GL-3, and sufficient chemical stabil-
ity for mobile hydraulic system service. JLG Industries
recommends Mobilfluid 424 hydraulic oil, which has an
SAE viscosity index of 152.
NOTE: When temperatures remain below 20° F (-7° C), JLG
Industries recommends the use of Mobil DTE 13M.
