Check all fluids daily. Engine must be cold and on a level surface.

Follow run-in procedure in engine manual. If unburned fuel and oil col- lect in exhaust pipe during run-in, see Section 10.

Fuel

Y Do not use gasoline. Gasoline

	will damage engine.
	Add fresh diesel fuel before starting
	engine the first time (see mainte-
	nance label for specifications). Fill
	fuel tank up to 1/2 in. (13 mm) from top
	to allow room for expansion. Open
	fuel shut-off valve.
	Do not run out of fuel or air enters fuel
	system and causes starting prob-
	lems. See engine manual to bleed air
	from fuel system.
	Oil
	After fueling, check oil with unit on lev-
	el surface. If oil is not up to full mark on
	dipstick, add oil (see maintenance la-
	bel).
	. Your unit may have the optional
	low oil pressure	shutdown
	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.
	. To improve cold weather starting:
	Keep battery in good condition.
	Store battery in warm area.
Full	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.
