These conditionscan cause hosedamageand deterio-
ration. Some hoses are more susceptible to these
conditions than others. Inspect all machine hydraulic
hoses frequently for signs of deterioration or damage:
Hard, cracked, cut, abraded, charred, leaking or
otherwise damaged hose.
Kinked, crushed, flattened or twisted hose.
Blistered, soft, degraded or loose hose cover.
Cracked, damaged or badly corroded hose fittings.
When replacinga hydraulic hose, besure that thehose
is straight (not twisted) before tightening the fittings.
This can be done by observing the imprint (layline) on
thehose.Usetwowrenches;holdthehosestraightwith

WARNING
Beforedisconnectingor performing any workon
hydraulic system, relieve all pressure in system
(seeRelievingHydraulic System Pressure inthis
section).
Keepbodyandhandsawayfrompinholeleaksor
nozzles that eject hydraulic fluid under high
pressure. Use paper or cardboard, not hands, to
search for leaks. Hydraulic fluid escaping under
pressure can have sufficient force to penetrate
the skin and cause serious injury. If fluid is in-
jected into the skin, it must be surgically re-
moved within a few hours by a doctor familiar
withthistypeofinjury.Gangrenemayresultfrom
such an injury.
