Do not operate the tool at oil temperatures above 140 °F (60 °C). Operation at higher temperatures can cause operator 

discomfort at the tool.

VISCOSITY 

(At min. and max. operating temps)

(20–82 centistokes)

When  choosing  hydraulic  fluid,  the  expected  oil  temperature  extremes  that  will  be  experienced  in  service  determine 

the most suitable  temperature viscosity characteristics. Hydraulic  fluids with a viscosity index over 140 will  meet the 

requirements over a wide range of operating temperatures.
