S-0683
Y Stop engine.
Y Do not touch hot exhaust
pipe, engine parts, or load
bank/grid.
Y Keep exhaust and pipe away
from flammables.
Y Do not perform run-in
procedure at less than 20
volts weld output and do not
exceed duty cycle or equip-
ment damage may occur.
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
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 load bank to generator
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 generator A/V control so
load equals rated voltage and
current of generator (see name-
plate, rating label, or the specifi-
cations section in this manual).
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.
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 turn off load bank to
remove load. Run engine several
minutes at no load.
Y Stop engine and let cool.
4 Engine Exhaust Pipe
Repeat procedure if wetstacking is
present.
