Cleaning the Mower

1. With the engine
running on a flat paved
surface, spray a stream
of water in front of the
right rear wheel.
The water will splash into the path of the blade,
cleaning out the clippings.
2. When no more clippings come out, stop the water
and move the mower to a dry area.
3. Run the engine for a few minutes to dry the
housing to prevent corrosion.
