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. start-up 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.
