ENGINE OIL LEVEL CHECK
Check the engine oil level with the engine stopped and in a level position.
1. Remove the filler cap/dipstick and wipe it clean.
2. Insert and remove the dipstick without screwing it into the filler neck. Check the oil level
shown on the dipstick.
3. If the oil level is low, fill to the edge of the oil filler hole with the recommended oil.
4. Screw in the filler cap/dipstick securely.
Running the engine with a low oil level can cause engine
damage.
The Oil Alert system (applicable engine types) will automatically stop the engine before the
oil level falls below safe limit. However, to avoid the inconvenience of an unexpected
shutdown, always check the engine oil level before startup.
ENGINE OIL CHANGE
Drain the used oil while the engine is warm. Warm oil drains quickly and completely.
1. Place a suitable container below the engine to catch the used oil, and then remove the
filler cap and the drain plug.
2. Allow the used oil to drain completely, and then reinstall the drain plug, and tighten it
securely.
Please dispose of used motor oil in a manner that is compatible with the environment.
We suggest you take used oil in a sealed container to your local recycling center or
service station for reclamation. Do not throw it in the trash; pour it on the ground; or
down a drain.
3. With the engine in a level position, fill to the outer edge of the oil filler hole with the

An incorrect spark plug can cause engine damage.
1. Disconnect the spark plug cap, and remove any dirt from around the spark plug area.
2. Remove the spark plug with a spark plug wrench.
3. Inspect the spark plug. Replace it if the electrodes are worn, or if the insulator is cracked
or chipped.
4. Measure the spark plug electrode gap with a suitable gauge.
The gap should be 0.028 -0.031 in (0.70 - 0.80 mm). Correct the gap, if necessary, by
carefully bending the side electrode.
5. Install the spark plug carefully, by hand, to avoid cross-threading.
6. After the spark plug seats, tighten with a spark plug wrench to compress the water.
If reinstalling the used spark plug ，tighten 1/8 - 1/4 turn after the spark plug seats.
If installing a new spark plug, tighten 1/2 turn after the spark plug seats.

7. STORAGE/ TRANSPORTING
STORING YOUR ENGINE
Storage Preparation
Proper storage preparation is essential for keeping your engine trouble free and looking
good. The following steps will help to keep rust and corrosion from impairing your engine’s
function and appearance, and will make the engine easier to start after storage.
Cleaning
If the engine has been running, allow it to cool for at least half an hour before cleaning.
Clean all exterior surfaces, touch up any damaged paint, and coat other areas that may
rust with a light film of oil.
lUsing a garden hose or pressure washing equipment can force water into the
air cleaner or muffler opening. Water in the air cleaner will soak the air filter,
and water that passes through the air filter or muffler can enter the cylinder,
causing damage.
lWater contacting a hot engine can cause damage. If the engine has been
running, allow it to cool for at least half an hour before washing.
Fuel
Gasoline will oxidize and deteriorate in storage. Old gasoline will cause hard starting, and
it leaves gum deposits that clog the fuel system. If the gasoline in your engine deteriorates
during storage, you may need to have the carburetor and other fuel system components
serviced or replaced.
The length of time that gasoline can be left in your fuel tank and carburetor without causing
functional problems will vary with such factors as gasoline 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 gasoline was not fresh when you filled the fuel tank.
The Distributor’s Limited Warranty does not cover fuel system damage or engine
performance problems resulting from neglected storage preparation.
You can extend fuel storage life by adding a fuel stabilizer that is formulated for that
purpose, or you can avoid fuel deterioration problems by draining the fuel tank and
carburetor.

17
ADDING A 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.
1. Add fuel stabilizer following the manufacturer’s instructions.
2. 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.
3. Stop the engine.
4. Move the fuel valve to the OFF position.
If engine has a KNOB FUEL SWITCH, then follow step 1 2 3 and 4, If
engine not has a KNOB FUEL SWITCH, then follow step 1 2 3.
DRAINING THE FUEL TANK AND CARBURETOR
1. Place an approved gasoline container below the carburetor, and use a funnel to avoid
spilling fuel.
2. Remove the carburetor drain bolt, and then pull out the fuel tube.
3. After all the fuel has drain into the container, reinstall the drain bolt and fuel tube.
Tighten them securely.
Storage Precautions
1. Change the engine oil.
2. Remove the spark plugs.
3. Pour a tablespoon (5-10 cc) of clean engine oil into the cylinder.
4. Pull the starter rope several times to distribute the oil in the cylinder.
5. Reinstall the spark plugs.

18
6. Pull the starter rope slowly until resistance is felt. This will close the valves so moisture
cannot enter the engine cylinder. Return the starter rope gently.
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.
Be sure all fuel has been drained from the fuel tank, to reduce the possibility of fuel
leakage.
Position the equipment so the engine is level. 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.
If equipped with a battery for an electric starter, recharge the battery once a month while
the engine is in storage. This will help to extend the service life of the battery.
Removal from Storage
Check your engine as described in the chapter CHECK BEFORE OPERATION.
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 cylinders were coated with oil during storage preparation, the engine may smoke
briefly at startup. This is normal.
TRANSPORTING
If the engine has been running, allow it to cool for at least 15 minutes before loading the
engine-powered equipment on the transport vehicle. A hot engine and exhaust system can
burn you and can ignite some materials.
Keep the engine level when transporting to reduce the possibility of fuel leakage.
