INSTALL - Continued.
Hydraulic fitting 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.
c.
Apply hydraulic fitting sealant to male threads
of 37° flare fittings. To protect against
hydraulic system clogging, do not apply
sealant to first thread turn of fittings.
When tightening a tube or hose
coupling nut (6), secure mating fitting
with backup wrench (5). Failure to
secure
mating
fitting
can
stress
connecting components and may
result
in
failure
of
tube
and
accessories.
d.
Install and tighten coupling nut (6) on 37° flare
fitting. Using backup wrench, tighten coupling
nut until firmly seated. Check 37° flare fittings
for leakage during system startup. At that
time, leaking 37° flare fittings can be tightened
as needed to stop leakage.
NOTE
Large diameter hydraulic hoses take
a set during initial hours of operation.
When installing a replacement hose,
it
must
be
manually
shaped
to
duplicate curvature and orientation of
the hose it replaces.
e.
When replacing a 1-1/2 in. (38 mm) diameter
hose, install and finger tighten one end of hose
first. With help of another person, use pipe
wrenches to rotate and bend hose to
approximate curvature of used hose and
connect remaining loose end of hose to fitting.
