Step 7. Check fuel supply to injectors.
WARNING
Severe burns, illness, or death may result if
personnel fail to handle diesel fuel oil
properly. Observe the following precautions:
· · Do not inhale vapor.
· · Do not check fuel supply near open flame,
sparks, or excessive heat.
· · Be certain fuel lines and connections are
not disconnected.
· Work in a well-ventilated area.
a. With engine cool, loosen line nuts on injectors one full turn. Check that
3-way selector valve is properly alined.
b. Hold a lint-free cloth around injector line nuts to collect leakage.
To prevent starter from overheating, do not
crank engine with starter for more than 10
seconds.
Battery life will be lengthened if 60 seconds
is allowed to elapse between starting attempts.
Under any condition, if engine does not start
on initial attempt, allow engine rotation to
stop completely before again engaging starter.
Prime the centrifugal pump as soon as possible
after engine starts. Rotation of impeller without
water in volute will damage pump components.
c. Without depressing pushbutton of fault sensitive control switch, push
START button and observe fuel flow from injector fittings until air
is cleared from lines.
If there is no fuel flow, replace fuel filter and clean fuel feed pump
strainer as described in table 4-1, step 4.
