| Symptom | Remedy |
|---|---|
| Accidental starting | Disconnect the battery cables before working on the engine. Remove the negative (–) lead first when disconnecting the battery. Reconnect the negative (–) lead last when reconnecting the battery. |
| Disabling the engine | Disable the engine as follows: 1) Disconnect the ignition coil. 2) Remove the battery cables, negative (–) lead first. Reconnect the negative (–) lead last when reconnecting the battery. |
| Battery acid cleanup | Add 500 g (1 lb.) of bicarbonate of soda (baking soda) to a container with 4 L (1 gal.) of water and mix the neutralizing solution. Pour the neutralizing solution on the spilled battery acid and continue to add the neutralizing solution to the spilled battery acid until all evidence of a chemical reaction (foaming) has ceased. Flush the resulting liquid with water and dry the area. |
| Battery short circuits | Disconnect the battery before maintenance. Remove all jewelry before servicing the equipment. Use tools with insulated handles. Remove the negative (–) lead first when disconnecting the battery. Reconnect the negative (–) lead last when reconnecting the battery. Never connect the negative (–) battery cable to the positive (+) connection terminal of the starter solenoid. Do not test the battery condition by shorting the terminals together. |
| Servicing the air cleaner | Do not operate the engine with the air cleaner/silencer removed. |
| Troubleshooting and/or repairing the sensors or the ECM | Make sure that the fuel supply is turned OFF and that the fuel supply valves are DISCONNECTED from the power source BEFORE turning the ECM power on. |
