WARN I N G
Personal injury or death can reult from sudden machine move-
DO NOT disconnect or remove anyhydraulic 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
At operating 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.
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

spills are cleaned up.
Many of these problems can creatediagnostic or event codes in the
