As long as you use the manifold heater switch and the purge pump, you must con-
tinue to hold the starter switch. That’s because the starter’s electrical circuit controls
the manifold heater’s current.
Once the engine is running smoothly at about 700 rpm, stop pumping. Release
the heater manifold switch and starter button, and increase rpm to 1,000-1,200 for
the warm-up period.
During warm-up and afterwards, don’t idle at less than 700 rpm. Low idling
causes engine cooling, not heating. When you idle your engine for long periods, use
high idle—1,500-1,600 rpm.
If you must idle at a lower speed, watch the exhaust. If you see white smoke,
increase the rpm to 1,500-1,600. If the engine misfires or blows heavy blue-white
smoke, you’ll have to blow out the induction and exhaust systems.
To do that, increase rpm to 1,600-1,800 for 30 seconds to one minute.
Stop the
engine fast if the power plant warning light comes on.
If the engine
won’t
start
Stop cranking after 15 seconds. Wait 3-5 minutes and try again. If it still won’t
start, don’t grind away on the starter. It’ll burn up and then the engine definitely
won’t start.
Follow the -10 TM troubleshooting procedures to get the tank started. If that
doesn’t work, it’s time to call your mechanic.
w
hat do a bear and your AVLB have in common, drivers? They both like to hiber-
nate when the weather gets cold!
Follow these steps to wake up that big diesel:
1.
Follow your -10 TM to the letter. Test for hydrostatic lock. Make sure all your
controls are set right.
2.
Pump the purge pump until you feel firm back pressure. It takes about a minute.
shouting won’t
help. there’s
only
one way
to get your
avlb out of
hibernation in
cold weather.
If the engine starts
Keep pumping the purge pump with steady strokes, holding the manifold heater
switch and the engine starter button until the tachometer reads 450-500 rpm.
