a. Relieve hydraulic system pressure.
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.
Care must be taken to ensure that fluids are contained during
performance of inspection, maintenance, testing, adjusting, and repair
of the product. Be prepared to collect the fluid with suitable containers
before opening any compartment or disassembling any component
Refer to Special Publication, NENG2500, "Dealer Service Tool
Catalog" for tools and supplies suitable to collect and contain fluids on
Dispose of all fluids according to local regulations and mandates.
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.
