14).
2. Change the engine oil
3. Pull the starter slowly until a resistance is felt. This closes the
valves and protects them from dust and corrosion.
4. Coat all surfaces liable to rust with a thin film of oil. Cover the
lawnmower and store it on a flat surface in a dry, dust free place.
Do not use a plastic cover since this retains dampness.
NOTE: If the lawnmower is to be stored for a period of more than 3
months, remove the spark plug and pour 5 to 10 cc of clean engine
oil into the cylinder; then pull the starter slowly 2 or 3 times to spread
the oil. Do not leave the lawnmower lying on its side over long
periods. This may cause difficult starting and gear oil leaks.
