Engine must be cold and on a level sur- face. See maintenance label (Section 9-2) for fluid specifications.

Starting engine for the first time:

Add fresh fuel to bottom of filler neck. Open fuel shut-off valve.

If coolant level is below bottom of radiator filler neck, add coolant to overflow bottle.

Run-in period (first 100 hours):

Engine may use oil and wetstacking may occur during run-in (see Section 12). Check oil several times daily during run-in.

Daily pre-start checks:

Add fresh fuel to bottom of filler neck.

Check oil. If oil is not up to full mark on dip- stick, add oil. Unit is shipped with 10W30 engine oil.

Check coolant level in overflow bottle. If

14coolant is below Low level, add coolant un- til level in tank is between Low and Full lev- els. If overflow bottle coolant level was low, check coolant level in radiator (see Sec- tion 9-2).

Engine damage can result from:

S Low oil level

S High engine temperature S Incorrect coolant mixture

S Running out of fuel (air in fuel lines) S Using gasoline

S Using ether to start engine S Wetstacking

Engine stops if oil pressure is low, engine coolant temperature is high, or fuel level is low. Some conditions may cause engine damage before the engine shuts down.

Oil: Check oil level often and do not use the oil pressure shutdown system to moni- tor oil level.

Engine Temperature: Incorrect engine temperature can damage engine. Do not run engine without a properly working ther- mostat and radiator cap.

Keep radiator and air intake clean.

Coolant: A solution of 50% ethylene gly- col base antifreeze and 50% water must be used in this engine. Do not use 100% antifreeze or severe damage will occur.

15Fuel: Engine will shut down if fuel level is low. Air in the fuel system causes starting problems.

Do not use gasoline. Using ether voids warranty.

Wetstacking: If unburned fuel and oil col- lect in exhaust pipe during run-in, see Sec- tion 12.

. To improve cold weather starting:

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 information.

Use correct grade oil for cold weather.
