.Check all engine fluids daily.

Engine must be cold and on a level surface. Unit is shipped with 20W break-in oil.

Automatic shutdown system stops engine if oil pressure is too low or coolant tempera- ture 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 10.

Fuel

YDo not use gasoline. Gasoline will damage engine.

The unit is shipped with enough fuel to pre- vent air from entering fuel system. Add fresh diesel fuel before starting (see engine main- tenance label for fuel specifications). Leave filler neck empty to allow room for expansion.

Do not run out of fuel or air will enter fuel sys- tem and cause 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).

Coolant

Check coolant level in radiator before start- ing unit the first time. If necessary, add cool- ant to radiator until coolant level is at bottom of filler neck.

Check coolant level in recovery tank daily. If necessary, add coolant to recovery tank until coolant level is between Cold Full and Hot Full levels. If recovery tank coolant level was low, also check coolant level in radiator. Add coolant if level is below bottom of radia- tor filler neck.

Unit is shipped with an engine coolant mix- ture of water and ethylene glycol base anti-

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.

YIncorrect engine temperature can damage engine. Do not run engine without a properly working thermo- stat and radiator cap.

.To improve cold weather starting: Use Preheat switch (see Section 6-2).

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 8-2).
