Recommended Hydraulic Oil
To protect the environment, LIFTON recommends the use of biodegradable oil.
Viscosity (ideal) .................................................................................................... 20-40 cSt
Viscosity (allowable)......................................................................................... 15-1000 cSt
Viscosity index .......................................................................................................Min. 100
Standard mineral or synthetic oil can be used.
When the tool works continuously, the oil temperature will steady at a certain level called
the oil working temperature. This will, depending on the nature of the job and the cooling
capacity of the system, be 20-40°C above the air temperature. At working temperature,
the oil viscosity must be within the ideal area. The tool may not be operated, if the oil
viscosity is not within the allowable area, or if the temperature is not within ÷20°
→
+70°C.
The viscosity index expresses the dependence of the viscosity on the temperature. That
is the reason why a high viscosity index is preferable, so that the oil can be used within a
wide temperature interval.
