Remove all dirt from exterior of engine and equip- ment.

Follow lubrication recommendations.

Refer to engine manual for correct engine storage instructions.

Store equipment in a clean, dry area. Do not store in an area where equipment is present that may use a pilot light or has a component that can create a spark.
