.Check all engine/compressor fluids daily.

Engine must be cold and on a level surface. Unit is shipped with 20W break-in oil. The 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 14.

Fuel

NOTICE − Do not use gasoline. Gasoline will damage engine.

Add fresh diesel fuel before starting to pre- vent air from entering the fuel system (see engine maintenance label for fuel specifica- tions). Leave filler neck empty to allow room for expansion.

Engine stops if fuel level is low on units with low fuel shutdown option. Do not run out of fuel or air may enter fuel system and cause starting problems. See engine manual to bleed air from fuel system.

Engine 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 for engine oil specifications).

Compressor Oil

1Compressor Oil Level Indicator (On Tank)

Check oil with unit on level surface. Add oil

if oil is not up to full mark on indicator (see maintenance label for oil specifications).

Cold Weather Starting

.To improve cold weather starting:

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

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 9-1).
