With the extension on the sediment valve, drain water
and crud into a clean glass container.
If the fuel is clear, you're OK. If the fuel does not run
clear, close the valve and report it to your mechanic.
Put drained fuel into an approved hazardous waste con-
tainer.
Never
dump it down a drain or onto the ground.
Get rid of any dirty fuel by opening the
fuel tank's sediment valve before opera-
tion. Clean up that dirty job by having
your mechanic make a valve extension.
Here's how:
* Cut a 16-in piece of 1/4-in rubber hose,
NSN 4720-01-164-7803, and slide it onto
a pipe fitting, NSN 4730-00-200-0531.
* Use a hose clamp, NSN 4730-00-908-
3195, to tighten down the hose.
* Screw the pipe fitting into the grader's
drain valve.
Drain Dirty Fuel
T
he diesel engine in your road grader can take a lot of punishment on the job. But
one thing it can't take is contaminated fuel.
Dirty fuel clogs the engine's fuel injectors. Over time, it causes hard starting,
engine knocking, misfiring, black exhaust and loss of power.
It's real simple: there is no fuel like clean fuel—always keep it free from dirt and
water!

A
fter you mechanics clean out the 130G
grader's battery boxes, check out the tool
box. It's right above the circle drive on the
vehicle's main frame.
Any water or mud that sits in the bottom
of the box will turn to rust. So eyeball the
area around the box's mounting bolts.
Enough rust in this area could let the box
fall off the frame!
Use a wire brush to scrape off rust and
old paint. After cleaning, protect the bare
metal inside the box with bituminous coat-
ing compound, NSN 8030-00-290-5141.

Wipe Away Crud
Before you start re-fueling, wipe off any dirt and water (that includes snow and
ice) from around the filler cap. If it's raining or dusty, wrap a clean rag around the
nozzle when you add fuel to the tank. When you're done, make sure the fuel cap is
snapped down tight to keep dirt and water out.
