TROUBLESHOOTING
IMPORTANT: It is essential that all operator safety mechanisms be connected and in proper operating
condition prior to mower use.
When a problem occurs, do not overlook the simple causes. For example, starting problems could be
caused by an empty fuel tank.
The following table lists some of the common causes of trouble. Do not attempt to service or replace
major items or any items that call for special timing of adjustments procedures. Have this work done by
your Service Dealer.
