Miller Electric Big Blue 251D manual Servicing Air Cleaner

8-3. Servicing Air Cleaner

		Y	Stop engine.
		Y Do not run engine without air
			cleaner or with dirty element. En-
			gine damage caused by using a
			damaged element is not covered
			by the warranty.
		. The air cleaner primary element can
	4		be cleaned but the dirt holding ca-
			pacity of the filter is reduced with
1			each cleaning. The chance of dirt
			reaching the clean side of the filter
			while cleaning and the possibility of
2			filter damage makes cleaning a risk.
			Consider the risk of unwarrantable
			equipment damage when determin-
	3		ing whether to clean or replace the
			primary element.
			If you decide to clean the primary
			element, we strongly recommend
		8	installing an optional safety element
			to provide additional engine protec-
	7		tion. Never clean a safety element.
			Replace the safety element after
			servicing the primary element three
			times.
