9-4. Overload Protection (Kohler-Powered Units)

Tools Needed:

!

Stop engine.

 

 

. If

the

unit is extremely over-

 

 

 

loaded, weld and generator pow-

 

 

 

er will stop. Turn unit off and re-

 

 

3/8 in

start

reset

the

generator

 

 

 

protection

circuit and restore

 

 

 

weld and generator power out-

 

 

 

put.

 

 

 

 

 

 

 

If the rated output of the unit is ex-

 

 

 

ceeded, engine speed may vary

 

 

 

rapidly until the weld or generator

 

 

 

power load is reduced.

 

 

1 Circuit Breaker CB4 (See Parts

 

1

 

List)

 

 

 

 

 

CB4

protects

the

generator

 

 

 

 

excitation circuit. If CB4 opens, there

 

 

will be no/low weld and generator

 

 

power output.

 

 

 

 

 

Press button to reset breaker.

 

 

2 Fuse F6 (See Parts List)

 

 

F6 protects the engine wiring

 

 

harness. If F6 opens, the engine

 

 

does not crank. If F6 opens while the

 

 

engine is running, the engine stops.

 

 

Replace fuse if open. Reinstall panel

before operating unit.

 

 

.

 

 

 

 

 

 

 

 

If a fuse or circuit breaker opens,

 

 

 

it usually indicates a more seri-

 

 

 

ous problem exists. Contact a
