.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 en- gine if fuel level or oil pressure is too low, or coolant 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 11.

Fuel

YDo not use gasoline. Gasoline will damage engine.

The unit is shipped with enough fuel to pre- vent air from entering fuel system but not enough fuel to prevent low fuel shutdown. Add fresh diesel fuel before starting to pre- vent low fuel shutdown (see engine mainte-

freeze rated to −34 ° F (−37 ° C). Add anti- freeze to mixture if using the unit in tempera- tures below −34 ° F (−37 ° C).

Keep radiator and air intake clean and free of dirt.

.To improve cold weather starting:

Use Starting Aid switch (see Section 6-1or 7-1).

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 in- formation.

Use correct grade oil for cold weather (see Section 9-2).
