INTRODUCTION
OPERATIONAL PERFORMANCE TESTS
Use operational performance test procedures to quan-
titatively check all system and functions on the ma-
chine.
Purpose of Performance Tests
1. To comprehensively evaluate each operational
function by comparing the performance test data
with the standard values.
2. According to the evaluation results, repair, adjust,
or replace parts or components as necessary to
restore the machine’s performance to the desired
standard.
3. To economically operate the machine under opti-
mal conditions.
Kinds of Tests
1. Base machine performance test is to check the
operational performance of each system such as
engine, travel, swing, and hydraulic cylinders.
2. Hydraulic component unit test is to check the
operational performance of each component such
as hydraulic pump, motor, and various kinds of
valves.
Performance Standards
“Performance Standard” is shown in tables to evaluate
the performance test data.
Precautions for Evaluation of Test Data
1. To evaluate not only that the test data are correct,
but also in what range the test data are.
2. Be sure to evaluate the test data based on the
machine operation hours, kinds and state of work
loads, and machine maintenance conditions.
The machine performance does not always deteriorate
as the working hours increase. However, the machine
performance is normally considered to reduce in pro-
portion to the increase of the operation hours. Accord-
ingly, restoring the machine performance by repair,
adjustment, or replacement shall consider the number
of the machine’s working hours.
Definition of “Performance Standard”
1. Operation speed values and dimensions of the new
machine.
2. Operational performance of new components ad-
justed to specifications. Allowable errors will be
indicated as necessary.
