1.7 LUBRICATION
Engine (Crankcase) Oil
NOTE: Crankcase oil must be a high quality detergent type
meeting one of the following API service classifica-
tions: CC/SE, CC/SF, CD/SE, CD/SF, CE/SF or CE/
SG.l
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 Kendall Hyken
052 hydraulic oil, which has an SAE viscosity of
10W-20 and a viscosity index of 152, or Mobilfluid
424, which has an SAE viscosity of 10W-30 and a
viscosity index of 152. Kendall Hyken 052 and Mobil-
fluid 424 are fully compatible and can be mixed as
necessary.
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 viscosities. If use of hydraulic oil other
than Kendall Hyken 052 or Mobilfluid 424 is desired,
contact JLG Industries for proper recommendations.
Kendall Hyken 052 and Mobilfluid 424 are fully com-
patible and can be mixed as necessary.
NOTE: When temperatures remain consistentlybelow 20
degrees F. (-7 degrees C), JLG Industries recom-
mends the use of Mobil DTE11.
Lubrication Specifications
NOTE: Refer to Figure 1-2 for specific lubrication proce-
dures.
