Storage Precautions; Removal From Storage - Honda HHT31S Owner's Manual

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
ignition switch is in the STOP (O) position.
Drain the fuel from the fuel tank to a suitable
container. Press the primer bulb a few times to
draw any remaining fuel out of the carburetor,
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 37). 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.

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. If 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.
