screws, alternating from side to side for a uniform fit,
until the wheel halves are drawn together (Fig. 35).

and tighten. Remove the 2 long screws or bolts and
replace them with 2 cap screws and 2 locknuts
(Fig. 35).

a spacer, and a locknut. Ensure that the spacer is

Storage
To prepare the lawn mower for off-season storage,
perform the recommended maintenance procedures. Refer
to Maintenance on page 15.
Store the lawn mower in a cool, clean, dry place. Cover
the lawn mower to keep it clean and protected.
Preparing the Fuel System
Warning
Gasoline can vaporize if you store it over long
periods of time and explode if it comes into
contact with an open flame.
Do not store gasoline over long periods of time.
Do not store the lawn mower with gasoline in
the fuel tank or the carburetor in an enclosure
with an open flame. (For example, a furnace or
a water heater pilot light.)
Allow the engine to cool before storing it 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 from the
crankcase. Refer to Changing the Engine Oil on
page 18.
2. Remove the spark plug (Fig. 12).
3. Using an oil can, add about one tablespoon of oil to
the crankcase 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.
