Troubleshooting Chart - General
Symptom Possible Cause(s)
Engine will not start 1. Engine switch is set to "OFF".
2. Fuel valve is turned to "CLOSE".
3. Choke is open.
4. Engine is out of gas.
5. Engine is filled with contaminated or
old gas
6. Spark plug is dirty.
7. Spark plug is broken.
8. Unit is not on level surface.
9. Oil is low.
Engine runs but 1. Circuit reset button is off.
there is no electrical
output 2. Bad connecting of wires / cables.
3. Bad electrical device connected to
generator / welder.
Generator / welder 1. Generator / welder is overloaded
runs but does not
support all electrical
devices connected. 2. Short in one of the connected devices.
3. Air cleaner is dirty.
Troubleshooting Chart - Generator
Symptom Possible Cause(s)
No output voltage 1. Engine speed is too slow
2. Open, shorted, or incorrect wiring
3. Faulty capacitor
4. Open or shorted field windings
5. Open diodes
6. Front panel switch set incorrectly
7. Circuit breaker tripped
Low output voltage 1. Engine speed is too slow
with no load 2. Open diodes
3. Faulty capacitor
4. Open or shorted fi eld windings
5. Voltage setting on front panel
incorrect
High output voltage 1. Faulty capacitor
with no load 2. Engine speed is too fast
3. Voltage setting on front panel
incorrect
Low output voltage 1. Open diode
under load 2. Engine speed too slow at full load
3. Excessive load applied
4. Voltage setting on front panel
incorrect
Erratic output 1. Unbalanced engine
voltage 2. Dirty, corroded, or loose wiring
connection
3. Unstable load applied
Noisy operation 1. Loose welder / generators or engine
bolt
2. Short circuit in welder / generators
field or load
3. Faulty bearing
★ These diagnostic and repair procedures should be performed by an authorized service center.
Corrective Action
1. Set engine switch to "ON".
2. Turn fuel valve to "OPEN" position.
3. Close the choke.
4. Add gas.
5. Change the gas in the engine.
6. Clean spark plug.
7. Replace spark plug.
8. Move unit to a level surface to prevent low oil shutdown from
triggering.
9. Add or replace oil.
1. Wait for 2 minutes and push the circuit reset button to the "ON"
position.
2. If you are using an extension cord, try a different one.
3. Try connecting a different device.
1. Turn off all electrical devices. Unplug all electrical devices. Turn off
generator / welder. Wait several minutes. Restart generator / welder.
Try connecting fewer electrical loads to the generator / welder.
2. Try disconnecting any faulty or short-circuited electrical loads.
3. Clean or replace air cleaner.

2. Adjust engine speed ★
3. Reduce the applied load
4. Adjust setting on front panel
1. Refer to engine manual
2. Referring to the wiring diagram, clean and reconnect all wiring ★
3. Remove all loads, then apply each one individually to determine which
one is causing erratic function
1. Tighten all mountings
2. Test winding resistance, replace fi eld winding if necessary ★
Test load devices for shorts. Replace defective load device.
3. Replace bearing
