2. Do not allow children to operate. Do not allow

PREPARATION
1. Do not wear loose fitting clothing that could get

4. When cleaning, repairing or inspecting, make
certain all moving parts have stopped. Disconnect
the spark plug wire, and keep the wire away from
the plug to prevent accidental starting.
Handle gasoline with care--it is highly flammable.

or hot engine or fill guel tank indoors. Wipe
up spilled gasoline.

tank inside of a building where fumes may reach
an open flame of spark. Allow the engine to cool
before storing in any enclosure.

leaves, wood chips, excessive grease and oil.

overspeed the engine. Excessive engine speeds
