.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.

Fuel

Add fresh fuel before starting engine the first

time (see engine maintenance label for fuel specifications).

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.

Engine coolant is a mixture of water and ethylene glycol base antifreeze. 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:

Keep battery in good condition. Store battery in warm area off concrete sur- face.

Use correct grade oil for cold weather (see Section 8-1).
