Hydraulic Hoses
Hydraulic hoses are subject to extreme conditions such
as pressure differentials during operation and exposure
to weather, sun, chemicals, very warm storage condi-
tionsormishandling duringoperation andmaintenance.
Theseconditionscancausedamageorprematuredete-
rioration. Some hoses are more susceptible to these
conditions than others. Inspect the hoses frequently for
signs of deterioration or damage.
WARNING
Before disconnecting or performing any work
on hydraulic system, relieve all pressure in
system. Stop engine; lower or support all cut-
ting units.
When replacing a hydraulic hose, be sure that the hose
is straight (not twisted) before tightening the fittings.
This can be done by observing the imprint on the hose.
Use two wrenches; hold the hose straight with one
wrench and tighten the hose swivel nut onto the fitting
with the other wrench.
Keepbodyandhandsawayfrompinholeleaks
or 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 injected into the skin, it must be surgi-
cally removed within a few hours by a doctor
familiar with this type of injury. Gangrene may
result from such an injury.
