our dozer came back from the paint shop looking like new.
But before you hop in the cab for the day’s run, eyeball the back of the fuel tank.
Make sure there’s a stenciled “Fll line” on the tank. It’s a quick reminder not to
overFll the tank.
When a tank is Flled to the brim, diesel fuel that spills causes fumes in the cab
area. Enough fumes will leave you lightheaded and nauseated.
If the paint line was painted
over, have your mechanic use
black CARC paint to stencil a
new Fll line at the bottom of
the Fller neck—about 3 inches
below the top of the fuel tank.
Below the Fll line, stencil
“CAUTION—DO NOT FILL
ABOVE THIS LINE TO
ALLOW FOR EXPANSION”
in 3-in letters. The stencils are
part of the Standard Automotive
Tool Set.
a
drop in temperature may cause a
“slow down” in your excavator’s upper
structure
when
it
traverses
during
operation.
But if it continues to move erratically
or at a snail’s pace, the structure needs
some lube now!
Two grease Fttings that lubricate the
structure’s swing bearing are located
directly under the access cover for the
boom’s hydraulic hoses.
Needless to say,
they get overlooked a lot!
So grab your grease gun and put
some “swing” back into the swing
bearing by following these steps from
Page 15-1 of TM 5-3805-280-10 (±eb 00).
Repeat this procedure three times to
get the right amount of lube into the
swing bearing.
1.±
Park the excavator on level ground.
2.±
Lower the bucket to the ground.
3.±
Turn the idle switch off.
4.±
Run the engine with the needle about
one third of the way up the rpm gauge,
without a load, for two minutes.
5.±
Decrease the rpm level to the slow idle
position.
6.±
Turn the key switch to OFF, then remove
the key.
7.±
Attach a “Do Not Operate” tag on the
right control lever inside the cab.
8.±
Pull the pilot control shut-off lever to
the locked position.
9.±
During scheduled services, give both
fittings ten shots of grease each.
10.±
Start the engine.
Raise the excavator’s
bucket several inches off the ground.
Turn the upper-structure 45 degrees.
