.
Check all engine fluids daily.
Engine must be cold and on a level surface.
The automatic shutdown system stops en-
gine if oil pressure is too low or coolant tem-
perature 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.
NOTICE − Follow run-in procedure in en-
gine manual. If unburned fuel and oil collect
in exhaust pipe during run-in, see Section
10.
Fuel
NOTICE − Do not use gasoline. Gasoline
will damage engine.
NOTICE − Do not use ether to start engine.
Add fresh diesel fuel before starting to pre-
vent air from entering the fuel system (see
OM-243 907 Page 26
NOTICE − Follow run-in
procedure in engine manu-

engine maintenance label for fuel specifica-
tions). Leave filler neck empty to allow room
for expansion.
Engine stops if fuel level is low.
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).
NOTICE − Engine may use oil and wets-
tacking may occur during run-in. Check oil
several times daily during run-in.
Coolant
Check coolant level in radiator before start-
ing unit the first time. Add coolant if below
bottom of filler neck (see Section 8-8 for ra-
diator filling instructions).
Check coolant level in recovery tank daily.
If coolant is below Cold Full level, add cool-
ant until level in tank is between Cold Full
and Hot Full levels. If recovery tank coolant
level was low, check coolant level in radiator
(see Section 8-8).
Remove air bleed screw
when filling radiator.
See Section 8-8.
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.
NOTICE − Incorrect engine temperature
can damage engine. Do not run engine with-
out a properly working thermostat and ra-
diator cap.
.
Check radiator coolant
level when fluid is low in
recovery tank.

To improve cold weather starting:
Use Engine Start/Preheat switch to op-
erate glow plug (see Section 6-1).
Keep battery in good condition. Store
battery in warm area.
Use fuel formulated for cold weather
(diesel fuel can gel in cold weather).
Contact local fuel supplier for fuel in-
formation.
Use correct grade oil for cold weather
(see Section 8-1).
