LUBRICATION
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 service2.
NOTE:
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 viscosi-
ties.

PRESSURE SETTINGS
Cold temperatures have a significant impact on pressure read-
ings. JLG Industries Inc. recommends operating the machine
until the hydraulic system has warmed to normal operating
temperatures prior to checking pressures. JLG Industries Inc.
also recommends the use of a calibrated gauge. Pressure read-
ings are acceptable if they are within ± 5% of specified pres-
sures.
