General Information
Hydraulic Hoses
Hydraulic hoses are subject to extreme conditions such
as, pressuredifferentials duringoperationand exposure
to weather, sun, chemicals, very warm storage condi•
tions or mishandling during operation or maintenance.
These conditions can cause damage or premature
deterioration. Some hoses are more susceptible to
these conditions than others. Inspect the hoses fre•
quently for signs of deterioration or damage.
WARNING
Before disconnecting or performing any work
on the hydraulic system, all pressure in the
system must be relieved by lowering the cut•
ting unit to the ground and stopping the
engine.
When replacing a hydraulic hose, be sure that the hose
is straight (nottwisted) beforetighteningthefittings.This
can be done by observing the imprint on the hose. Use
two wrenches; one to hold the hose straight and one to
tighten the hose swivel nut onto the fitting.
Keep body and hands away from pin hole
leaks 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 do serious
damage. If fluid is injected into the skin, it
must be surgically removed within a few
hours by a doctor familiar with this type of
injury or gangrene may result.
