Troubleshooting & Repair
TROUBLESHOOTING
While normal care and routine maintenance will extend the life of your chipper/shredder, prolonged or constant use may eventually require that service be performed to allow it to continue operating properly. The troubleshooting guide below lists the most common problems, causes and remedies.
See the service information on the following pages for instructions on how to do most of these minor repairs yourself. If you prefer, all of these procedures can be performed for you by your local authorized dealer.
WARNING
Never attempt to perform any of these procedures with the engine running. Always turn the engine off, let the rotor come to a complete stop, and disconnect the spark plug wire from the spark plug before attempting to correct any operating problems.
Failure to comply with this safety requirement can result in serious personal injury to you or bystanders.
