STORAGE
Adding Fuel Stabilizer to Extend Fuel Storage
Life
When adding a fuel stabilizer, fill the fuel tank with
fresh gasoline. If only partially filled, air in the tank
will promote fuel deterioration during storage. If
you keep a container of gasoline for refueling, be
sure that it contains only fresh gasoline.
Add fuel stabilizer following the manufacturer's
instructions.
After adding a fuel stabilizer, run the engine
outdoors for 10 minutes to be sure that treated
gasoline has replaced the untreated gasoline in
the carburetor.
Draining the Fuel Tank and Carburetor
Disconnect the spark plug cap. Make sure the
engine switch is in the STOP position.
Drain the fuel from the fuel tank to a suitable
container. Press the priming bulb a few times to
then drain this fuel from the tank.
Engine Oil
Change the engine oil (see page 26).
Carburetor & Air Cleaner
Clean the air filter (see page 27) and move the
choke lever to the CLOSED position.
Blade
If a blade is installed, put the blade cover on the
blade.
Engine Cylinder
Remove the spark plug (see page 28). Pour a 1/4
tablespoon (1 - 3 cc) of clean engine oil into the
cylinder. Pull the starter rope several times to
distribute the oil in the cylinder. Reinstall the
spark plug. Pull the starter rope slowly until
resistance is felt then return the starter grip
gently. This closes the valves so moisture cannot
enter.
, draw any remaining fuel out of the carburetor,
STORAGE PRECAUTIONS
If your trimmer 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.
With the engine and exhaust system cool, cover
the trimmer 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 non-
porous cover will trap moisture, promoting rust
and corrosion.
REMOVAL FROM STORAGE
Check your trimmer as described in the BEFORE
OPERATION chapter of this manual.
If the fuel was drained during storage preparation,
fill
the tank with fresh gasoline. I f you keep a
container of gasoline for refueling, be sure that 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.
