before cleaning, repairing or inspecting the unit. Engine
should be turned off and cool, spark plug wire must be
removed from spark plug before any repairs or adjustments
are attempted. Never make adjustments or repairs with the
engine (motor) running. Disconnect the spark plug wire,
and keep the wire away from the plug to prevent accidental
starting. Remove the ignition key if equipped with an electric
start.
