1.4 TORQUE REQUIREMENTS
When maintenance becomes necessary or a fastener has
loosened, refer to the applicable Torque Chart in this sec-
tion of the manual to determine proper torque values for
various size fasteners.

NOTE:
All dimensions are given in inches (in), with the met-
ric equivalent, centimeters (cm), given in parenthe-
ses.
1.6 SERIAL NUMBER LOCATIONS
For machine identification, a serial number plate is affixed
to the machine. The plate is mounted on the base frame
between the front caster wheels under the front cover. The
serial number is also stamped on the front of the mast
assembly near the amber beacon.
1.7 LUBRICATION
Hydraulic Oil
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 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 recom-
mends using Mobil DTE 13 hydraulic oil.
Aside from JLG r ecommendations, 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.
