4-4. Engine Prestart Checks

Full

Capacity: 9 qt (8.5 L)

Full

Check all fluids daily. Engine must be cold and on a level surface.

Follow run-in procedure in engine manual. If unburned fuel and oil collect in exhaust pipe during run-in, see Section 9.

1 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. Open fuel shut-off valve.

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.

2 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.

.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.

3 Coolant

Add coolant if level is below bottom of radia- tor filler neck. Engine coolant is a mixture of water and ethylene glycol base antifreeze. Add anti-freeze to mixture if using unit in

temperatures below 0° F (–18°C).

Valve Open

Ref. ST-155 331-B / Ref. ST-154 954

Keep radiator, air intake, and cooling fins clean and free of dirt.

YIncorrect engine temperature can

damage engine. Do not run engine without a properly working 180°F (80°C) thermostat and a 7 psi (48 kPa) 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.
