Normal maintenance, replacement or repair of emission control devices and systems may be performed by any
repair establishment or individual; however, warranty repairs must be performed by a Kohler authorized
service center.
For safety and health reasons, many states require special licensing or certifi cation for servicing LPG/NG fuel
systems. Check local and state regulations before choosing a repair establishment to perform fuel system repairs.
WARNING: Accidental Starts!
Disabling engine. Accidental starting can cause severe injury or death. Before working on the engine or equipment,
disable the engine as follows: 1) Disconnect the spark plug lead(s). 2) Disconnect negative (-) batt ery cable from batt ery.
Before disconnecting the negative (-) ground cable, make sure all switches are off . If on, a spark will occur at the ground cable
