LUBRICATION
Hydraulic Oil
NOTE: Hydraulic oils must have anti-wear qualities at least
to API Service Classification GL-3, and sufficient
chemical stability for mobile hydraulic system ser-
vice. JLG Industries recommends Mobilfluid 424
hydraulic oil, which has an SAE viscosity of 10W-30
and a viscosity index of 152.
NOTE: When temperatures remain consistently below 20° F
(-7° C) JLG recommends the use of Mobil DTE11
hydraulic oil.
NOTE: Operate lift function through one complete cycle
before checking oil level. Oil level should read at
full mark or within 1/2" below full
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 Mobilfluid 424 is desired, contact JLG Indus-
tries for proper recommendations.

SERIAL NUMBER LOCATIONS
For machine identification, a serial number plate is affixed
to the machine. The serial number plate is located on the
left rear side of the machine frame, just above the left rear
tire and wheel assembly. In addition, if the serial number
plate is damaged or missing, the machine serial number is
stamped on the right front of the frame. Cylinder Specifi-
cations.
