truck and the trailer to prevent equip-
ment damage.
The pump’s fuel tank has a vent
valve in the cap. During normal opera-
tions, set this valve to the OPEN posi-
tion to release the pressure that builds
up in the tank.
Don’t worry about the engine oil
pressure reading until the engine is run-
ning. Before you start the engine, the
oil pressure gauge may show a read-
ing. Disregard it. The gauge is elec-
tronic, and it may show the oil pres-
sure before the engine was last shut
down. Then, when you pull out the
START/STOP switch to make a start,
the gauge will show 0 pressure. The
real reading is the one taken when the
engine is running.

The pump uses a 12-volt starting
system. It has two 12-volt batteries con-
nected in parallel. If you use jumper
cables to start the pump, hook them up
across only one battery in the slaving
vehicle and one battery in the pump.
Don’t overtighten the battery
holddowns. Snug will do. Too tight can
crack the battery case.
Set both fuel shutoff valves to
the same position—TANK or FUEL
AUX—before you try to start the en-
gine. Otherwise, it won’t start no
matter how long you crank the starter.
For fording or swimming, however,
set the valve to the CLOSED position
so water cannot get into the fuel.
Eyeball the underside of the fuel cap
to make sure the valve is set correctly
for your operation. See Para 2-11 of
TM 10-4320-324-14 for the details.
Pull the tow bar out as far as pos-
sible before towing the pump. You
can hook up the bar while it’s in the
stowed position, but there won’t be
enough maneuver room between the
