DRAINING THE FUEL TANK AND CARBURETOR

1. Remove the carburetor bowl
drain bolt and sealing
washer with a 10 mm
wrench, and drain the
carburetor bowl fuel into an
approved gasoline container.
2. Move the fuel valve lever to
the ON position (see
page 3). This will allow the
fuel tank to drain through the
carburetor bowl.
3. After draining the carburetor and fuel tank, install the drain bolt and
sealing washer and tighten securely.

ENGINE OIL

1. Change the engine oil (see
page 5).
2. Remove the spark plug (see
page 6) and pour a
tablespoon (5 - 10 cc) of
clean engine oil into the
cylinder. Using the recoil,
crank the engine a few
revolutions to distribute the
oil in the cylinder, then
reinstall the spark plug.
3. Pull the starter rope slowly until resistance is felt. This closes the
valves and will help to protect the engine from internal corrosion.

STORAGE PRECAUTIONS

If your engine will be stored with gasoline in the fuel tank and
carburetor, it is important to reduce the hazard of gasoline vapor
ignition. Select a well-ventilated storage area away from any appliance
that operates with a flame, such as a furnace, water heater, or clothes
dryer. Also avoid any area with a spark-producing electric motor, or
where power tools are operated. If possible, avoid storage areas with
high humidity, because that promotes rust and corrosion. If there is
gasoline in the fuel tank, leave the fuel valve in the OFF position (see
page 4). Keep the engine level during storage. Tilting can cause fuel or
oil leakage. With the engine and exhaust system cool, cover the
engine to keep out dust. A hot engine and exhaust system can ignite
or melt some materials. Do not use sheet plastic as a dust cover. A
nonporous cover will trap moisture around the engine, promoting rust
and corrosion.

REMOVAL FROM STORAGE

Check your engine as described in the BEFORE OPERATION
CHECKS section of this manual (see page 3). If the fuel was drained
during storage preparation, fill the tank with fresh gasoline. If you keep
a container of gasoline for refueling, be sure it contains only fresh
gasoline. Gasoline oxidizes and deteriorates over time, causing hard
starting. If the cylinder was coated with oil during storage preparation,
the engine will smoke briefly at startup. This is normal.

TRANSPORTING

Keep the engine level when transporting to reduce the possibility of
fuel leakage. Turn the fuel valve to the OFF position (see page 4).
