NOTE:	(22° C)	(22° C)	(22° C)	(22° C)

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

Filter

Min. full-flow filtration Sized for flow of at least:

(For cold temp. startup and max. dirt-holding capacity)

25 microns	25 microns	25 microns	25 microns
30 gpm	30 gpm	30 gpm	30 gpm
(114 lpm)	(114 lpm)	(114 lpm)	(114 lpm)

Hydraulic fluid Petroleum based	100-400 ssu*	100-400 ssu*	100-400 ssu*	100-400 ssu*
(premium grade, anti-wear, non-conductive)		(20-82 centistokes)
Viscosity (at min. and max. operating temps)

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.
