ENGINE PROBLEMS

 

 

 

Engine will not idle down to low

 

 

1.

Idler Switch on HIGH Idle.

 

 

 

speed. (For Codes 10158, 10160

 

 

2.

Engine choke is not fully open.

 

 

 

only.)

 

 

3.

External load on welder or

 

 

 

 

 

 

 

auxiliary power. - Remove load.

 

 

 

 

 

 

4.

Machine output is under load or

 

 

 

 

 

 

 

idle switch in wrong position.

 

 

 

 

 

 

5.

Idle solenoid does not pull in.

 

 

 

Engine idles down to low idle but

 

 

1.

Engine low idle RPM may be set

 

 

 

will not stay at low idle. (For Codes

 

 

 

too low. - Contact Lincoln Field

 

 

 

10158, 10160 only.)

 

 

 

Service Facility.

 

 

 

 

 

 

 

 

 

 

 

Engine will not go to high idle when

 

 

1.

Check Work and Electrode

 

 

 

attempting to weld or use generator

 

 

 

cables for loose or faulty

 

 

 

power. (For Codes 10158, 10160

 

 

 

connections.

 

 

 

only.)

 

 

2.

Mechanical linkage from

 

 

 

 

 

 

 

solenoid to engine stuck.

 

 

 

 

 

 

3.

Open connection in weld circuit.

 

 

 

 

 

 

4.

No output from receptacles or

 

 

 

 

 

 

 

load too small.

 

 

 

 

 

 

5.

Idler pc board is not sensing

 

 

 

 

 

 

 

output current.

 

 

 

 

 

 

6.

Faulty idler pc board.

 

 

 

Engine will not go to high idle when

 

 

1.

Auxiliary load less than 100

 

 

 

using auxiliary power. (For Codes

 

 

 

watts.

 

 

 

10158, 10160 only.)

 

 

2.

Circuit breaker CB1 or CB2

 

 

 

 

 

 

 

tripped or faulty.

 

 

 

 

 

 

3.

Mechanical linkage from

 

 

 

 

 

 

 

solenoid to engine stuck.

 

 

 

 

 

 

 

 

 

 

 

Engine runs erratic or stops running

 

 

1.

Oil level may be low activating

 

 

 

or engine surges at low idle. (For

 

 

 

the engine “Oil Gard” shutdown

 

 

 

Codes 10158, 10160 only.)

 

 

 

system. - Check oil level.

 

 

 

 

 

 

2.

Idle solenoid linkage or engine

 

 

 

 

 

 

 

idle misadjusted.

 

 

 

 

 

 

 

 

 

 

 

Recoil starter is hard to pull.

 

 

1.

Crankcase may be over-filled

 

 

 

 

 

 

 

with oil. - Check oil level.

 

 

 

Engine will not start or starts but

 

 

1.

Water in engine from rain and / or

 

 

 

runs rough with low power.

 

 

 

condensation. - Remove spark plug and

 

 

 

 

 

 

 

dry it if wet. Blow low pressure compressed

 

 

 

 

 

 

 

air in spark plug port while pulling recoil

 

 

 

 

 

 

 

starter. Re-install spark plug.

 

 

 

 

 

 

2. Spark plug may be faulty.

 

 

 

 

 

 

3. Air filter element saturated with water and /

 

 

 

 

 

 

 

or oil - Replace.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

RECOMMENDED COURSE OF ACTION

If all recommended possible areas of misadjustment have been checked and the problem persists,

Contact your local Lincoln Authorized Field Service Facility.

CAUTION

If for any reason you do not understand the test procedures or are unable to perform the tests/repairs safely, contact your local Authorized Field Service Facility for technical troubleshooting assistance before you proceed.
