INSTALL TAPERED PIPE THREAD FITTINGS.
Pipe sealant can cause eye damage
or skin irritation. Wash after skin
contact. Wear safety goggles/glasses
when using. Avoid contact with eyes
or skin. If sealant contacts eyes,
flush
eyes
with
water
and
get
immediate medical attention.

Apply pipe sealant to tapered pipe threads of
fitting (16).
b.
Install and tighten fitting (16) in mating
component (17) until snug. Connect tube or
hose per step c.
c.
Check fitting for leaks during system startup. If
leaking, loosen connecting tube or hose and
tighten hydraulic fitting, then retighten tube or
hose.
4.
INSTALL HYDRAULIC HOSES AND TUBES.
Use caution when installing tubes.
Do not bend kink, or twist tubes
during installation. Bends, kinks, and
twists can lead to tubing breaks
during equipment operation.
NOTE
If installing auxiliary or propulsion
system hoses and/or tubes, you
should
perform
pump
priming
procedure per step D at this time.
Some of the hydraulic hoses used in
the
paving
machine
are
routed
between and under other hoses and
components. This task refers to
these hoses as "embedded hoses
a.
If replacing an embedded hose, use a male-to-
male adapter from hydraulic systems test and
repair tool outfit (HSTRU) to connect used and
replacement hoses. Lubricate outer surface of
replacement hose and if possible, outer
surface of embedded hose, where it can be
reached, with petrolatum. With help from
another person, route replacement hose by
pulling free end of used hose from equipment.
NOTE
Refer
to
paragraph
2.55
for
installation
details
applicable
to
specific valve panel components.
b.
Route new hoses and tubes. Do not allow
tubes to bend, crimp, or twist. Provide
maximum bend radius at hose turns to prevent
hose crimping.
