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.
When you are using hydraulic cylinders and puller studs, always ensure
that the rated capacity of the puller stud meets or exceeds the rated
capacity of the hydraulic cylinder. If the puller stud does not meet or
exceed the rated capacity of the hydraulic cylinder, a sudden failure of
the puller stud could occur. The sudden failure of the puller stud could
result in personal injury or death.
Personal injury can result from hydraulic oil pressure and hot oil.
Hydraulic oil pressure can remain in the hydraulic system after the
engine has been stopped. Serious injury can be caused if this pressure is
not released before any service is done on the hydraulic system.
Make sure all of the work tools have been lowered to the ground, and
the oil is cool before removing any components or lines. Remove the oil
filler cap only when the engine is stopped, and the filler cap is cool
enough to touch with your bare hand.
