POTENTIAL HAZARD
Gasoline can vaporize if stored over long
periods of time.
WHAT CAN HAPPEN
Vaporized fuel can explode if it comes into
contact with open flame.
HOW TO AVOID THE HAZARD
Do not store gasoline (fuel) over long periods of
time.
Do not store lawn mower with fuel in the tank
in an enclosure with an open flame. (Example:
a furnace or water heater pilot light.)
Allow the engine to cool before storing in any
enclosure.
Empty the fuel tank when mowing the last time before
storing the lawn mower.
1. Run the lawn mower until the engine stops from
running out of fuel.
2. Prime the engine and start it again.
3. Allow the engine to run until it stops. When you can
no longer start the engine, it is sufficiently dry.
Preparing the Engine
1. While the engine is still warm, change the oil in the
crankcase. Refer to Changing the Engine Oil on
page 14.
2. Remove the spark plug (Fig. 31).
3. Using an oil can, add about one tablespoon of oil
through the spark plug hole.
4. Slowly rotate the engine several times using the starter
rope to distribute the oil.
5. Install the spark plug but do not connect the wire to
the spark plug.
General Information
1. Clean the lawn mower housing. Refer to Cleaning the
Underside of the Lawn Mower Housing on page 15.
