1.10 SERIAL NUMBER LOCATIONS
A serial number plate is affixed to the left rear side of the
frame. If the serial number plate is damaged or missing,
the machine serial number is stamped on the left side of
the frame.
1.11 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 index of
152.
NOTE: When temperatures remain below 20° F (-7 degrees
C), JLG Industries recommends the use of Mobil
DTE 13M.
Aside from JLG recommendations, it is not advisable to
mix oils of different brands or types, as they may not con-
tain the same required additives or be of comparable vis-
cosities. If use of hydraulic oil other than Mobilfluid 424 is
desired, contact JLG Industries for proper recommenda-
tions.
