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. Gaso-
	line will damage engine.
	Add 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
	problems. See engine manual to
	bleed air from fuel system.
	Oil
	After fueling, check oil with unit on
	level surface. If oil is not up to full
	mark on dipstick, add oil (see main-
	tenance label).
	. Engine stops if oil pressure is
	too low.
	. To improve cold weather
	starting:
	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.
Full	Use correct grade oil for cold
	weather.
