Capacity: w/Overflow

Tank 6.9 qt (6.5 L)

Open Valve

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 low or engine tem- perature is high.

.This unit has a low oil pressure shut- down switch. However, some condi- tions may cause engine damage be- fore the engine shuts down. Check oil level often and do not use the oil pressure shutdown system to moni- tor oil level.

Follow run-in procedure in engine manu- al. If unburned fuel and oil collect in ex- haust 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 la- bel for specifications). Fill fuel tank up to 1/2 in. (13 mm) from top to allow room for expansion. Open fuel shut-off valve.

Do not run out of fuel or air enters fuel system and causes starting problems. See engine manual to bleed air from fuel system.

Oil

After fueling, check oil with unit on level surface. If oil is not up to full mark on dip- stick, add oil (see maintenance label).

YEngine may use oil and wetstack- ing may occur during run-in. Check oil several times daily dur- ing run-in.

Coolant

Check coolant level in radiator before starting unit the first time. Add coolant if below bottom of filler neck (see Section 4-4 for radiator filling instructions).

Check coolant level in recovery tank dai- ly. If coolant is below Cold Full level, add coolant 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 4-4).

Engine coolant is a mixture of water and ethylene glycol base antifreeze. A solu- tion of 50% antifreeze and 50% water must be used in this engine. Do not use 100% antifreeze or severe damage will occur.

Keep radiator and air intake clean.

YIncorrect engine temperature can damage engine. Do not run engine without a properly working ther- mostat 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.
