1.11 TORQUE SPECIFICATIONS
1.12 LUBRICATION SPECIFICATIONS
Refer to Section 1.17, Operator Maintenance & Lubrica-
tion, for specific lubrication procedures.
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.
Aside from JLG recommendations, it is not advis-
able 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 Mobil DTE 11M is desired, contact JLG
Industries for proper recommendations.
1.13 CRITICAL STABILITY WEIGHTS
DO NOT REPLACE ITEMS CRITICAL TO STABILITY WITH ITEMS
OF DIFFERENT WEIGHT OR SPECIFICATION (FOR EXAMPLE: BAT-
TERIES, FILLED TIRES, PLATFORM) DO NOT MODIFY UNIT IN
ANY WAY TO AFFECT STABILITY.
