HYDROSTATIC MOTOR EFFICIENCY TEST
This test can be used to check the operating
efficiency of the motor.
IMPORTANT: When connecting a flowmeter into the
pump/motor circuit, make sure the meter is
connectedproperly and the control lever is stroked in
the direction being tested. If not, the hydrostatic
system and/or flowmeter may be damaged.
Efficiency Test Procedure
