1.5 TORQUE REQUIREMENTS
* Check swing bearing bolts for security after first 50
hours of operation and every 600 hours thereafter.
1.6 LUBRICATION
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. JLG Industries recommends Mobilfluid 424
hydraulic oil, which has an SAE viscosity index of
152.
NOTE: When temperatures remain consistently below 20
degrees F. (-7 degrees C.), JLG Industries recom-
mends the use of Mobil DTE11.
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. If use of hydraulic oil other than Mobilfluid 424 is
desired, contact JLG Industries for proper recommenda-
tions.
Some machines may be specially equipped with Mobil
EAL224H biodegradable and non-toxic hydraulic oil. This
oil is vegetable oil based and possesses the same anti-
wear and rust protection characteristics as mineral oils,
but will not adversely affect ground water or the environ-
ment when spilled or leaked in small amounts. Mobil
EAL224H has a viscosity of 34 cST at 40° C and a viscosity
index of 213. The operating range of this oil is -18° C to
+83° C.
IT IS RECOMMENDED THAT MOBIL EAL224H HYDRAULIC OIL BE
STORED ABOVE FREEZING (0° C) AS THE OIL MAY APPEAR
CLOUDY AFTER EXPOSURE TO LOW TEMPERATURES FOR
EXTENDED PERIODS OF TIME. THE CLOUDINESS WILL DISAPPEAR
WHEN THE OIL IS WARMED TO AT LEAST 10° C AND AGITATED. DO
NOT ATTEMPT TO "THIN" THE OIL WITH NO.2 DIESEL FUEL. FOR
BEST RESULTS, STORE THE OIL ABOVE FREEZING.
NOTE: Accidentally mixing Mobil EAL224H hydraulic oil with
other mineral oils will cause no loss of performance
characteristics. However, biodegradability may be
reduced and toxicity may be increased, depending
on the oil and level of contamination.
