O
perators, when the vehicle sits idle for several weeks at a time, make sure you
prime the backhoe loader’s (BHL) turbocharger during start up. Do the same when
the engine’s oil Flter gets replaced.

this
CAUTION
statement scattered throughout TM
5-2420-231-10.
That’s
because
the impeller inside the engine’s
turbocharger
needs
lubrication
when it Frst starts and warms up.
Without oil being pumped into
the impeller’s bearings, they can
burn out. Then you’re stuck while
your BHL goes to support or a DOL
shop for a ruined turbocharger. Did
someone say heavy chump change
and unnecessary downtime?
o
perators, don’t leave the curbside door in the open position next to the exhaust pipe
while the excavator idles.
It doesn’t take long for the heat from the exhaust to cook the mirror. The heat will crack
the mirror’s glass, especially in cold weather. Also, the mirror’s plastic housing will melt. Talk
about
á la mode!
So, make sure you close the door after you open it, or at least keep it away from the
exhaust pipe.
