FUEL

NOTICE
Depending on the region where you operate your equipment, fuel
formulations may deteriorate and oxidize rapidly. Fuel deterioration and
oxidation can occur in as little as 30 days and may cause damage to the
carburetor and/or fuel system. Please check with your servicing dealer for local
storage recommendations.
Petrol will oxidize and deteriorate in storage. Old petrol will cause hard
starting, and it leaves gum deposits that can clog the small passages in the
fuel system. If the petrol in your mower deteriorates during storage, you
may need to have the carburetor and other fuel system components,
serviced or replaced.
The length of time that petrol can be left in your fuel tank and carburetor
without causing functional problems will vary with such factors as petrol
blend, your storage temperatures, and whether the fuel tank is partially or
completely filled. The air in a partially filled fuel tank promotes fuel
deterioration. Very warm storage temperatures accelerate fuel
deterioration. Fuel deterioration problems may occur within a few
months, or even less if the petrol was not fresh when you filled the fuel
tank.
If you keep a container of petrol for refueling, be sure that it contains only
fresh petrol.
If it will take more than 3 months to use the fuel in your storage container,
we suggest adding a fuel stabilizer to the fuel when you fill the container.
Short Term Storage (30-90 days)
If your lawnmower will not be used for 30 to 90 days, we recommend the
following to prevent fuel-related problems:
1. Add fuel stabilizer following the manufacturer's instructions.
When adding a fuel stabilizer, fill the fuel tank with fresh petrol. If only
partially filled, air in the tank will promote fuel deterioration during
storage.
Note:
– All stabilizers have a shelf life and their performance will deteriorate
over time.
– Fuel stabilizers will not reconstitute stale fuel.
2. After adding a fuel stabilizer, run the engine outdoors for 10 minutes to
be sure that treated petrol has replaced the untreated petrol in the
carburetor.
3. Stop the engine and turn the fuel valve to the OFF position.
4. Start the engine and continue to run the engine until it stops from the
lack of fuel in the carburetor fuel bowl. Running time should be less
than 3 minutes.
Long Term or Seasonal Storage (greater than 90 days)
Start the engine and allow it to run long enough to empty all the petrol
from the entire fuel system (including the fuel tank). Do not allow petrol to
remain in your engine for more than 90 days of inactivity.
The WARRANTY does not cover fuel system damage or engine
performance problems resulting from neglected storage preparation.

ENGINE OIL

Change the engine oil (page 12).

ENGINE CYLINDER

If the mower is to be stored for more
than 3 months, remove the spark plug
(page 12). Pour 5 ~ 10 cc of clean engine
oil into the cylinder [1]. Pull the starter
grip several times to distribute the oil in
the cylinder. Reinstall the spark plug.
Pull the starter grip slowly until
resistance is felt, then return the starter grip gently. This will close the
valves so moisture cannot enter the engine cylinder.

PLACING IN STORAGE

Since your mower will be stored with petrol in the fuel tank and
carburetor, it is important to reduce the hazard of petrol 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.
Place the mower with its wheels on a level surface. Tilting can cause fuel or
oil leakage. The handlebar can be folded for compact storage, shown
below.
With the engine and exhaust system cool, cover the mower 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 mower, promoting rust and corrosion.

REMOVING FROM STORAGE

Check your mower as described in PREPARATION AND CHECKS BEFORE USE
(page 4).
If the cylinder was coated with oil during storage preparation, the engine
will smoke briefly at startup. This is normal.

TRANSPORT

BEFORE LOADING

If the engine has been running, allow it to cool for at
least 15 minutes before loading the mower on the transport vehicle. A hot
engine and exhaust system can burn you and can ignite some materials.
Turn the fuel valve to the OFF position (page 9). This will prevent
carburetor flooding and reduce the possibility of fuel leakage.

HADLEBAR FOLDING

1. Remove the grass catcher. You can place it on top of the engine, with
the catcher opening to the front.
2. Support and hold the handlebar.
3. Unlock the handlebar adjust knobs

into the storage position.
NOTICE
Do not allow the control cables
while folding the handlebar down into the storage position. The cables or
engine control system may be damaged causing the lawnmower to not
function properly.
