1.6 MAJOR COMPONENT WEIGHTS
DO NOT REPLACE ITEMS CRITICAL TO STABILITY WITH ITEMS OF DIFFERENT
WEIGHT OR SPECIFICATION (FOR EXAMPLE: BATTERIES, FILLED TIRES, PLAT-
FORM) DO NOT MODIFY UNIT IN ANY WAY TO AFFECT STABILITY.
1.7 HYDRAULIC OIL
NOTE: Hydraulic oils require anti-wear qualities at least API Ser-
vice Classification GL-3, and sufficient chemical stability
for mobile hydraulic system service.
NOTE: 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.
OIL SAMPLING
This machine is equipped with an oil sampling valve to
allow for verification of hydraulic oil condition. Refer to
Section 5 - Hydraulics for Oil Sampling procedures.
