Htma Requirements - Stanley IDO7 Service Manual

HTMA Requirements

Hydraulic System
Requirements
Flow rate
Tool Operating Pressure
(at the power supply outlet)
System relief valve setting
(at the power supply outlet)
Maximum back pressure
(at tool end of the return hose)
Measured at a max. fluid viscosity of:
(at min. operating temperature)
Temperature
Sufficient heat rejection capacity
to limit max. fluid temperature to:
(at max. expected ambient temperature)
Min. cooling capacity
at a temperature difference of
between ambient and fluid temps
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.
Filter
Min. full-flow filtration
Sized for flow of at least:
(For cold temp. startup and max. dirt-holding
capacity)
Hydraulic fluid
Petroleum based
(premium grade, anti-wear, non-conductive)
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.
*SSU = Saybolt Seconds Universal
NOTE: These are general hydraulic system requirements. See tool Specification page for tool specific
requirements.
