Troubleshooting

⚠WARNING

 Turn OFF the machine, allow all moving parts to come to a complete stop, and disconnect the

spark plug wire before moving the machine, emptying the bag, unclogging the inlets or outlets,

filling the gas tank, or performing maintenance and repairs.

 While normal care and regular maintenance will extend the life of your equipment, prolonged or

constant use may eventually require that service be performed to allow it to continue operating

properly.

 To avoid serious injury, perform maintenance on the unit only when the engine is stopped.

 Always disconnect the spark plug wire and fasten it away from the plug before beginning the

maintenance, to prevent accidental starting of the engine.

Review the troubleshooting and procedures in this section to fix your machine if a problem develops.
