7.8 DECK
The underside of the mower deck should be cleaned after each use to remove any grass clippings, leaves
and dirt. These residues contain active organic substances that favor rust and corrosion. The deck may be
cleaned by tilting the mower and scraping clean with a suitable tool (make certain the spark plug is
disconnected).
Always lay the mower on that side where the air filter is directed upwards. The air filter lying face
down will lead to fuel and oil spills.
