At operating temperature, the hydraulic oil is hot and under pressure.
Hot oils can cause burns.
To prevent possible personal injury, release the pressure in the work
tool hydraulic circuit (boom, stick, bucket, and swing), travel circuits,
and the hydraulic oil tank at the filler cap before any hydraulic lines or
components are disconnected or removed.
Remove the filler cap only when the engine is stopped and the filler cap
is cool enough to touch.
Cylinders equipped with lock valves can remain pressurized for very
long periods of time, even with the hoses removed.
Failure to relieve pressure before removing a lock valve or
disassembling a cylinder can result in personal injury or death.
Ensure all pressure is relieved before removing a lock valve or
disassembling a cylinder.
