Severe thermal burns can occur on contact.

Combustible debris, such as leaves, grass, brush, etc. can catch fire.

	Fuel System

Maintenance

Fuel can become stale when stored over 30 days. Stale fuel causes acid and gum deposits to form in the fuel system or on essential carburetor parts. Mix fuel stabilizer with the fuel in the tank or storage container. Run the engine for a short time to circulate stabilizer through the carburetor and engine. Engine and fuel can then be stored up to 24 months.

If fuel stabilizer is used, you do not need to drain the gasoline prior to storage. If fuel stabilizer is not used, run the engine until it stops from lack of fuel.

Clean engine

Clean engine of surface debris, chaff, or grass.

Storage Area

Store in a clean, dry area. Do not store in the same area as a stove, furnace, water heater, or other appliance that uses a pilot light or has a device that can create a spark.
