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

YDo 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).

YEngine 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.

802 330-B

Keep radiator and air intake clean and free of dirt.

YIncorrect 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.
