Viscosity Index ...............................................Min. 100
Standard mineral or synthetic oil can be used.
Applicable Oil Types
When the tool works continuously, the oil temperature
will steady at a certain level called the oil working
temperature. Depending on the nature of the job and
the cooling capacity of the system, the oil working
temperature will be 20 °C to 40 °C (68 °F to 104 °F)
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 °C to 70 °C (–4 °F to 158 °F).
The viscosity index expresses the dependence of the
viscosity on the temperature. Thus, a high viscosity
index is preferable so that the oil can be used within
a wide temperature interval.
