Stop engine. Disconnect

If the unit is extremely over-
loaded, weld and generator
power will stop. Turn unit off
and restart to reset the genera-
tor protection circuit and re-
store weld and generator pow-
er output.
If the rated output of the unit is
exceeded, engine speed may
vary rapidly until the weld or
generator power load is re-
duced.

Fuse F1 (See Parts List)
F1 protects the generator excitation
circuit. If F1 opens, there is no/low
weld and generator power output.

Fuse F6 (See Parts List)
F6 protects the engine wiring sys-
tem. If F6 opens, the engine does
not crank. If F6 opens while the en-
gine is running, the engine stops.
Replace any open fuses. Reinstall
cover before operating.
If a fuse opens, it usually indi-
cates a more serious problem
exists. Contact a Factory Au-
thorized Service Agent.
