HTMA 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. 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 FLUID
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 require-
ments over a wide range of operating temperatures.
