9-1. Wetstacking

1	Welding Generator
Run diesel engines near rated out-
put during run-in period to properly
seat piston rings and prevent wets-
tacking. See nameplate or rating
label to find rated output.
. Do not idle engine longer than
2	necessary. Piston rings seat
	faster if engine runs at weld/
	power rpm, and the welding
	generator is kept loaded during
	run-in.
2	Engine Exhaust Pipe
Wetstacking is unburned fuel and
oil in the exhaust pipe and occurs
during run-in if the engine is run too
long at light load or idle rpm.

	If exhaust pipe is coated with a wet,
	black, tar-like substance, dry the
	engine using one of the following
1	run-in procedures.
	See the engine manual for addition-
	al engine run-in information.
