T
he right amount of clean hydraulic fluid will lubricate the small emplacement
excavator’s components and keep ‘em operating smoothly. That is, if the hydraulic
hoses are in good shape.
Hoses get brittle from constant exposure to the elements. Hoses to the front loader
bucket get the worst of this exposure—especially where they bend and mount into
the shutoff valves.
Brittle hoses can leak, then there’s not enough hydraulic pressure to operate the
front loader bucket.
So eyeball each hose, including
the ones tucked behind other hoses.
Look for oil stains behind or along
the bottom of each hose. A Class
III leak deadlines the SEE.
Always wear safety goggles
when tracking down a leak—oil
can be forced out of a pinhole-
sized opening with damaging
force. If you find a leaking or dam-
aged hose, call in your mechanic to
replace the hose—ASAP!
Check hoses for
cracks and oil stains
well,
that’s
one
reason you
should keep
my hoses in
good shape!
it’s a chilling
story, bonnie!
but
-there’s a
lesson
in it.
“ice or snow on hills or
curves can mean
trouble
.
speeds must be adjusted
for road conditions.”
I just heard
about private
unser’s accident.
what happened?
winter weather
brings lots of
hazards. snow…
sleet… ice…
Things a
driver’s
got to be
ready for.
