WARN I N G
Injury or death to personnel can result from sudden machine move-
ment.
DO NOT disconnect or remove any hydraulic system line or fitting
unless engine is shut down and hydraulic system pressure has been
relieved. Tighten all connections before applying pressure. Escaping
hydraulic fluid under pressure can penetrate skin, causing injury to
personnel.
At opening temperature, hydraulic oil is hot. Allow hydraulic oil to
cool before disconnecting any hydraulic lines. Failure to follow this
warning may result in injury to personnel.
To prevent injury to personnel, wear protective eye covering and
gloves.

CAU T I ON
Wipe area clean around all connections to be opened during removal. Cap
lines and hoses and plug openings after removing lines. Contamination of
system could result in premature failure.
N OT E
Tag hoses prior to removal to ensure correct installation.
Use a container to catch any fluid that may drain from hoses or sys-
tem. Dispose of fluid IAW local policy and ordinances. Ensure all
spills are cleaned up.
This section provides probable causes to known problems. Since
there may be several probable causes, specific inspections or instru-
ment tests may be recommended. These inspections and tests will
help to identify causes that are the most probable.
Make sure you use an oil with the correct viscosity for operating
conditions.
Ensure that the tasks in Brake System Tests, Inspections, and Adjust-
ments (WP 0015 00) have been performed before continuing with
troubleshooting.
Many of these problems can create diagnostic or event codes in ET.
These codes can help find the root cause of a problem. ET should be
used to retrieve logged and active codes.
