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

HYDRAULIC FLUID
100–400 ssu*
100–400 ssu*
100–400 ssu*
100–400 ssu*
Petroleum based
(Premium grade, anti-wear, non-conductive)
VISCOSITY
(At min. and max. operating temps)
(20–82 centistokes)
NOTE:
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.
