(22) Hose Couplings - The swivel nut at the end of each hose assembly is a free turning part which holds the
nipple tightly against the companion fitting. There will be some binding as the nut bears tight against the flare of the
nipple. Always hold the Hex Collar of the nipple stationary as the swivel nut is tightened or loosened. This prevents
damage to the hose.

HOW TO USE THE TROUBLE SHOOTING GUIDE ON
PAGE 45
1. In the "Troubles" listed across the top of the following
page, find the symptom which most closely describes the
actual problem with the paver hydraulic system.
2. Follow the guide line downward from that problem to
the circled No. . Then follow the guide line to the right
hand column where a probable cause and remedy is listed.
The cause shown for No.
will be the most common
occurrence and the remedy will often require the easier
checking and corrective work. A remedy may be given
outright, or may be a reference to manual pages and
paragraphs which give complete details on function,
maintenance, test, or repair of the component part
suspected of malfunction.
3. If the No. cause is not the actual problem proceed
to the No.
on that same vertical guide line and-make the
check or correction suggested. If that also fails to produce
the solution proceed to No. etc.
As the circled number of a cause and remedy goes
higher, the work required for making the check and
correction usually increases.
The higher numbered
possibilities are also less common in occurrence. For these
reasons it is wise to start with and progress numerically.
