10-3. Run-In Procedure Using Resistance Grid

		!	Stop engine.
		! Do not touch hot exhaust
			pipe, engine parts, or load
6			bank/grid.
		!	Keep exhaust and pipe away

	2		from flammables.
		NOTICE − Do not perform run-in

		procedure at less than 20 volts weld
		output and do not exceed duty
		cycle or equipment damage may
		occur.
		1	Resistance Grid
	1	Use grid sized for generator rated
		output.
		Turn Off grid.
		2	Welding Generator
		Place A/V range switch in maxi-
		mum position, A/V control in mini-
		mum position, and Output Selector
		switch (if present) in either DC
		position.
		3	Weld Cables
		Connect grid to generator weld
		output terminals using proper size
		weld cables with correct connec-
		tors (polarity is not important).
		4	Voltmeter
		5 Clamp-On Ammeter
3	5	Connect voltmeter and ammeter as
		shown, if not provided on generator.
		Start engine and run for several
		minutes.
		Set grid switches and then ad-
		just generator A/V control so
4		load equals rated voltage and
		current of the generator (see

		nameplate, rating label, or the
		specifications section in this
		manual).
+		Check generator and meters after
		first five minutes then every fifteen
		minutes to be sure generator is
		loaded properly.
		NOTICE − Check oil level frequent-
		ly during run-in; add oil if needed.

It is recommended to run the weld- ing generator for two hours mini- mum and up to four hours under load. Place A/V control in minimum position, then shut down grid to remove load. Run engine several minutes at no load.

! Stop engine and let cool.

6 Engine Exhaust Pipe

Repeat procedure if wetstacking is present.
