Do NOT remove hydraulic tank filler cap or disconnect or remove any hydraulic system line or fitting
unless hydraulic system pressure has been relieved. Hydraulic system pressure can be over 2,500 psi
(17,237 kPa), even with engine and pump off. To relieve pressure, lower all hydraulic attachments to the
ground and shut down engine. Move control levers through all operating positions, then slowly loosen
hydraulic tank filler cap. After maintenance, tighten all connections before applying pressure. Escaping
hydraulic fluid under pressure can penetrate skin, causing injury or death.
Hydraulic oil is very slippery. Immediately wipe up any spills. Failure to follow this warning may cause
Wipe area clean around all connections prior to removal. Cap hydraulic oil lines and plug openings after
removal. Contamination of hydraulic system could result in premature failure.
Use container to capture draining hydraulic oil. Dispose of hydraulic oil IAW local policy and ordi-
nances. Ensure all spills are cleaned up.
Tag hose and tube assemblies prior to removal to ensure correct installation.
