.
Check all engine fluids daily.
Engine must be cold and on a level surface.
Unit is shipped with 20W break-in oil. The
Automatic shutdown system stops engine if
oil pressure is too low or coolant tempera-
ture 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.
Y Do not use ether to start engine.

tions). Leave filler neck empty to allow room
for expansion.
Do not run out of fuel or air may enter fuel
system and cause starting problems. See
engine 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. 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 4-6 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 4-6).
Check radiator coolant
level when fluid is low in
recovery tank.

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.
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:
Use Engine Start/Preheat switch to op-
erate glow plug (see Section 5-1).
Keep battery in good condition. Store
battery in warm area off concrete sur-
face.
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 7-1).
