Precautions for Hydraulic Testing

The most effective method for isolating problems in the hydraulic system is by
using hydraulic test equipment such as pressure gauges and flow meters in the
various hydraulic circuits to perform various operational checks (refer to the
Special Tools (page 2–13)).
Remember that pressure specifications that appear on hydraulic schematics are
the design specifications for the specific component. Actual system pressure
will vary depending on fluid temperature, the location of the test port, and the
specific components used in the hydraulic circuit.
The hydraulic test procedures listed in this manual represent actual
performance for this machine. To correctly measure product or
component performance, be sure to follow the test procedures
provided.
All obvious areas such as fluid supply, filter, binding linkages, loose fasteners,
or improper adjustments must be checked before assuming that a hydraulic
component is the source of the problem.
Keep body and hands away from pin hole leaks or nozzles that eject
hydraulic fluid under high pressure. Do not use hands to search
for leaks; use paper or cardboard. Hydraulic fluid escaping under
pressure can have sufficient force to penetrate the skin and cause
serious injury. If fluid is injected into the skin, it must be surgically
removed within a few hours by a doctor familiar with this type of
injury. Gangrene may result from such an injury.
Failure to use gauges with recommended pressure (psi) rating as
listed in test procedures could result in damage to the gauge and
possible personal injury from leaking hot hydraulic fluid.
All testing should be performed by two (2) people. One person
should be in the seat to operate the machine, and the other should
read and record test results.
