HTMA / EHTMA REQUIREMENTS
HTMA
HYDRAULIC SYSTEM REQUIREMENTS
Flow Range
Nominal 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. fl uid viscosity of:
(at min. operating temperature)
Temperature: Suffi cient heat rejection
capacity to limit max. fl uid temperature to:
(at max. expected ambient temperature)
Min. cooling capacity at a temperature
difference of between ambient and fl uid
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-fl ow fi ltration
Sized for fl ow of at least:
(For cold temp. startup and max.
dirt-holding capacity)
Hydraulic fl uid Petroleum based
(premium grade, anti-wear, non-conductive)
Viscosity (at min. and max. operating temps)
NOTE:
When choosing hydraulic fl uid, the expected oil temperature extremes that will be experienced in service determine the
most suitable temperature viscosity characteristics. Hydraulic fl uids with a viscosity index over 140 will meet the requirements
over a wide range of operating temperatures.
