Multi-Viscosity Oils (SF, SF-SE, SF-CC, SF-CD).
* Not recommended for severe service - including high
RPM operation.
Deutz F3L912/F3L1011 Engine.
Single Viscosity Oils (CD-SE, CD-SF).
Multi-Viscosity Oils (CD-SE, CD-SF).
* This viscosity can be used at colder temperatures only
with engine oil preheating.
Wisconsin VG4D Engine.
Single Viscosity Oils (MS or SD).
Multi-Viscosity Oils (MS, SD, SE).
NOTE: Crankcase oil should meet one of the following API
classification grades: SE/CC, SE/CD, SF/CC, SF/
CD.
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 of 10W-30
and viscosity index of 152.
When temperatures remain consistently below +20°
F. (-7° C.), an amount of no. 2 diesel fuel, not to
exceed 20% of system capacity, may be added to
the hydraulic oil reservoir. This diesel fuel will “thin”
the hydraulic oil for easier cold weather operation,
and will almost completely dissipate from the hydrau-
lic system over a several month period of time. When
cold weather is past, it may be necessary to drain
and refill the hydraulic system to rid the system of
any remaining diesel fuel.
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 is desired or Mobilfluid 424,
contact JLG Industries for proper recommendations.
