or starts up and then stops
immediately
1) Engine switch (28) at position OFF
2) Lack of or insufficient oil in the motor
3) Faulty motor stopping device (oil-alert)
4) Lack of fuel in tank or fuel tap closed
5) Dirty or faulty spark plug
6) Cold motor
7) Other causes
1) Position switch to ON
2) Refill or top off
3) Replace
4) Refill the tank. Open the fuel tap
5) Clean or check and eventually replace
6) Hold down the CHOKE button, after start-up,
for a longer period of time
7) Consult the motor Operating Manual.
The motor does not accelerate.
Inconstant speed.
Too little power provided by
motor.
1) Air or fuel filter clogged
2) Bad gasoline
3) Overload
1) Check the air filter
2) Drain fuel tank and carburetor. Refuel with
fresh gasoline
3) Check the connected loads and if necessary

No current under no-load con-
ditions in weld mode
1) Faulty welding control board
2) Faulty Hall sensor
3) Chopper welding bridge broken
4) Faulty alternator
1) Ask for intervention of Service Department
to replace the board.
2) Ask for intervention of Service Department
to replace the Hall sensor.
3) Ask for intervention of Service Department
to replace the Chopper Bridge.
4) Disconnect the welding and auxiliary power
cables. Use a voltmeter to check that there
is 48 Vac at the outputs in weld and appro-
ximately 145 Vac between the outputs in
generation. Carry out the check when the
engine idles (disconnect one of the two
wires to the solenoid).
Irregular or inconsistent wel-
ding current
1) Faulty welding control board
2) Faulty Hall sensor
3) Chopper bridge short circuit
