OPERATIONAL PERFORMANCE TEST / Introduction
PREPARATION
TESTS
Observe the following rules in order to carry out
performance tests accurately and safely.
THE MACHINE
1. Repair any defects and damage found, such as
oil or water leaks, loose bolts, cracks and so on,
before starting to test.
TEST AREA
1. Select a hard and flat surface.
2. Secure enough space to allow the machine to
run straight more than 300 m (984 ft 3 in), and to
make a full swing with the front attachment ex-
tended.
3. If required, rope off the test area and provide
signboards to keep unauthorized personnel
away.
PRECAUTIONS
1. Before starting to test, agree upon the signals to
be employed for communication among cowork-
ers. Once the test is started, be sure to commu-
nicate with each other using these signals, and to
follow them without fail.
2. Operate the machine carefully and always give
first priority to safety.
3. While testing, always take care to avoid acci-
dents
due
to
high-voltage power lines. Always confirm that
there is sufficient space for full swings.
4. Avoid polluting the machine and the ground with
leaking oil. Use oil pans to catch escaping oil.
Pay special attention to this when removing hy-
draulic pipings.
MAKE PRECISE MEASUREMENT
1. Accurately calibrate test instruments in advance
to obtain correct data.
2. Carry out tests under the exact test conditions
prescribed for each test item.
3. Repeat the same test and confirm that the test
data obtained can be produced repeatedly. Use
mean values of measurements if necessary.
