Troubleshooting - Lambretta Uno50 Owner's Manual

TROUBLESHOOTING

1. Scooter won't start, electric starter doesn't operate
Check to make sure that the ignition is in the "ON" position, and that the engine stop switch
is in the "RUN" position. The starter will not run unless either the front or rear brake is
engaged. Check to make sure that both battery leads are securely connected, and check
fuses. If no other problem is found, the battery may be dead or the starter may be broken.
Try kick starting. The battery may need to be recharged or replaced.
2. Scooter won't start, electric starter operates slowly
Check that battery terminals are securely connected and clean. Battery may be low. Get
battery charged to prevent battery damage. Try kick starting.
3. Scooter won't start but starter operates or kick starting fails
Check fuel level. Check that battery cables are securely connected and that fuses are intact.
If the engine has been flooded due to a failed start attempt, wait an hour for the fuel to
evaporate off of the spark plug and retry. The fuel may have gone stale or there may be an
electrical problem. Take the scooter to your Lambretta dealer for service.
4. Scooter starts, but runs poorly
The fuel in your scooter may have deteriorated, is of poor quality, is not 91 octane minimum
or the scooter may be out of adjustment or need service. Take your scooter to your
Lambretta dealer for service before operating further.
5. Scooter runs, but gauges or lights don't work
Check battery connection and fuses. If this does not correct the problem, the battery may be
low or damaged. Take your scooter to your Lambretta dealer for service.
