4-2. Engine Prestart Checks
Ref. 802 579-B
1/2 in
(13 mm)
Full
Diesel
Check all fluids daily. Engine must be cold
and on a level surface. Unit is shipped with
10W30 engine oil.
Engine stops if oil pressure is too low or en-
gine temperature is too high.
. This unit has a low oil pressure shut-
down switch. However, some condi-
tions may cause engine damage before
the engine shuts down. Check oil level
often and do not use the oil pressure
shutdown system to monitor oil level.
Follow run-in procedure in engine manual. If
unburned fuel and oil collect in exhaust pipe
during run-in, see Section 9.
Fuel
Y Do not use gasoline. Gasoline will
damage engine.
Add fresh diesel fuel before starting engine
the first time (see maintenance label for
specifications). Fill fuel tank up to 1/2 in. (13
mm) from top to allow room for expansion.
Do not run out of fuel or air enters fuel sys-
tem and causes starting problems. See en-
gine manual to bleed air from fuel system.
Oil
After fueling, check oil with unit on level sur-
face. If oil is not up to full mark on dipstick,
add oil (see maintenance label).
Y Engine may use oil and wetstacking
may occur during run-in period.
Check oil several times daily during
run-in.
Coolant
Check coolant level in recovery tank before
starting unit the first time. Add coolant if
coolant is below bottom of radiator filler neck
(see Section 4-3 for radiator filling instruc-
tions.
Check coolant in recovery tank daily. If cool-
ant is below Full level, add coolant until cool-
ant level in tank is between Full and Low lev-
els. If recovery tank coolant level was low,
also check coolant level in radiator (see
Section 4-3).
Engine coolant is a mixture of water and
ethylene glycol base antifreeze. A solution
of 50% antifreeze and 50% water must be
used in this engine. Do not use 100% anti-
freeze or severe damage will occur.
Keep radiator and air intake clean and free
of dirt.
Y Incorrect engine temperature can
damage engine. Do not run engine
without a properly working thermo-
stat and radiator cap.
. To improve cold weather starting:
Keep battery in good condition. Store
battery in warm area off concrete
surface.
Use fuel formulated for cold weather
(diesel fuel can gel in cold weather).
Contact local fuel supplier for fuel
information.
Use correct grade oil for cold weather.
