service with the engine or blade running. STOP blade. 
STOP engine. Set brake. Remove key. Remove spark 
plug wire from spark plug and secure wire away from 
spark plug. Engine and components can be extremely 
hot. Avoid burns by allowing engine and components 
sufficient time to cool. Wear heavy leather gloves 
when handling or working around cutting blades.
