9.2Run-In Procedure Using Load Bank

S-0683

YStop engine.

YDo not touch hot exhaust pipe, engine parts, or load bank/grid.

YKeep exhaust and pipe away from flammables.

1 Load Bank

Turn all load bank switches Off. If needed, connect load bank to 115 volts ac wall receptacle or genera- tor auxiliary power receptacle.

2

Welding Generator

 

4

Set Amperage control at min.

 

 

3

Weld Cables

 

 

Connect load bank to generator

2

1

weld output terminals using proper

size weld cables with correct

 

 

connectors. Observe correct

 

 

polarity.

 

 

Start engine and run for several minutes.

Set load bank switches and then adjust Amperage control so load and output are 180 A.

Check generator and load bank meters after first five minutes then every fifteen minutes to be sure generator is loaded properly.

. Check oil level frequently dur-

 

ing run-in; add oil if needed.

3

After one hour (minimum), place Amperage control in minimum posi- tion, then turn off load bank to remove load. Run engine several minutes at no load.

YStop engine and let cool.

4 Engine Exhaust Pipe

Repeat procedure if wetstacking is present.
