General Information
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-
tions, or mishandling during operation or maintenance.
These conditions can cause damage or premature dete-
rioration. Some hoses are more susceptible to these
conditions than others. Inspect the hoses frequently for
signs of deterioration or damage.
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 and
tighten the hose swivel nut onto the fitting with the other.
Before disconnecting or performing any
work on hydraulic system, all pressure in
system must be relieved by stopping the
engine and lowering or supporting the
box and/or other attachment.
Keep body and hands away from pin hole
leaks or nozzles that eject hydraulic fluid
under high pressure. Use paper or card-
board, 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 surgical-
ly removed within a few hours by a doctor
familiar with this type of injury. Gangrene
may result from such an injury.
WARNING
Hydraulic Fitting Installation
O–Ring Face Seal
1. Make sure both threads and sealing surfaces are
free of burrs, nicks, scratches, or any foreign material.
2. Make sure the O–ring is installed and properly
seated in the groove. It is recommended that the O–ring
be replaced any time the connection is opened.
3. Lubricate the O–ring with a light coating of oil.
4. Put the tube and nut squarely into position on the
face seal end of the fitting and tighten the nut until finger
tight.
5. Mark the nut and fitting body. Hold the body with a
wrench. Use another wrench to tighten the nut to the cor-
rect flats from finger tight (F.F.F.T.). The markings on the
nut and fitting body will verify that the connection has
been tightened.
