Serial Number Locations
For machine identification, a serial number plate is affixed to
the machine. The plate is located on the back of the mast, just
above the mast support bracket.
1.2 LUBRICATION
NOTE:
Also see Lubrication Interval Chart - Table 1-5., Lubrication Intervals for Various
Components in this section of the manual.
Hydraulic Oil
Hydraulic oils must have anti-wear qualities at least to API Ser
-
vice Classification GL-3, and sufficient chemical stability for
mobile hydraulic system service. JLG Industries, recommends
Standard UTTO hydraulic oil, which has an SAE viscosity of
10W-30 and a viscosity index of 152.
For cold weather applications, i.e. when temperatures remain
consistently below +20°F (–7°C) JLG recommends using Mobil
DTE 13 hydraulic oil.
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 Standard UTTO is desired, contact
JLG Industries for proper recommendations.
