Observe the following rules in order to carry
out performance tests accurately and safely.
The machine
Repair any defects and damage found,
such as oil or water leaks, loose bolts,
cracks and so on, before starting to test.
Test area
Select a hard, flat surface.
Secure enough space to allow the
machine to run straight more than 20m,
and to make a full swing with the front
attachment extended.
If required, rope off the test area and
provide signboards to keep unauthorized
personnel away.
Precautions
Before starting to test, agree upon the
signals to be employed for communication
among coworkers. Once the test is
started, be sure to communicate with each
other using these signals, and to follow
them without fail.
Operate the machine carefully and always
give first priority to safety.
While testing, always take care to avoid
accidents due to landslides or contact with
high voltage power lines. Always confirm
that there is sufficient space for full swings.
Avoid polluting the machine and the
ground with leaking oil. Use oil pans to
catch escaping oil. Pay special attention
to this when removing hydraulic pipings.
Make precise measurements
Accurately calibrate test instruments in
advance to obtain correct data.
Carry out tests under the exact test
conditions prescribed for each test item.
Repeat the same test and confirm that the
test data obtained can be procured
