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 minimum operating temperature)
Temperature: Suffi cient heat rejection capacity to limit
maximum fl uid temperature to:
(At maximum expected ambient temperature)
Minimum cooling capacity at a temperature diff erence 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 minimum full-fl ow fi ltration
Sized for fl ow of at least:
(For cold temp startup and maximum dirt-holding capacity)
Hydraulic fl uid, petroleum based (premium grade, anti-
wear, non-conductive) Viscosity (at minimum and maximum
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.
