Cleaning the Cooling Fins
Air must pass freely through the cylinder cooling fins to
prevent poor engine performance and shortened engine
life. Regularly check and clean all debris from the cooling
fins by removing the engine cover (Fig. 17).

Servicing the Muffler and
Exhaust Ports
The muffler must be removed and serviced after each
100 hours of use. The exhaust ports must be cleaned and
inspected at the same time. Contact an authorized Toro
dealer for this service.
Adjusting the Idle Speed
Idle speed is the only available adjustment.
Do not tamper with the carburetor setting to increase the
maximum engine speed.
If adjustment is needed, have it performed by your
authorized Toro service dealer. Carburetor adjustments are
made at the factory and are not adjustable without
disassembling the carburetor.
Storage
For storage over 30 days, perform all regular maintenance
procedures and needed repairs, then complete the
following procedure:
1. If you are not using an oil formulated with a fuel
stabilizer/conditioner , add a petroleum based
stabilizer/conditioner to fuel in the tank. Follow
mixing instructions from stabilizer manufacturer
(1 oz. per gallon). Do not use an alcohol based
stabilizer (ethanol or methanol).

Note: A fuel stabilizer/conditioner is most effective when
mixed with fresh gasoline and used at all times.
IMPORTANT: Do not store stabilizer/conditioned
gasoline over 90 days.
2. Run the engine to distribute conditioned fuel through
the fuel system (5 minutes).
3. Stop the engine, allow it to cool, and drain the fuel
tank by disconnecting the fuel-return line from the
carburetor. Then gently hold the tickler lever down
while pumping the primer bulb until fuel stops
discharging from the fuel-return fitting.
4. Restart the engine and run it until it stops.
5. Prime the engine.
6. Start and run the engine until it will not start again.
Use the primer, several times to ensure no fuel remains
in primer system.
7. Dispose of fuel properly. Recycle as per local codes.
8. Remove the spark plug and insert a small amount of
oil into the cylinder. Slowly pull the starter cord and
bring the piston to a position closest to the spark plug
hole. Re-install the spark plug.
9. Apply a thin coating of oil to all the metal surfaces and
store the backpack blower in a dry place.
Emission Control
Information
To protect the environment in which we all live, Kawasaki
has incorporated an exhaust emission control system (EM)
in compliance with acceptable regulations of the
California Air Resources Board.
Fuel Information
This engine is certified to operate on unleaded regular
grade gasoline only. A minimum of 87 octane of the
antiknock index is recommended. The antiknock index is
posted on service station pumps in the USA.
Exhaust Emission Control
System (EM)
The exhaust emission control system applied to this
engine consists of a carburetor and an ignition system
having optimum ignition timing characteristics.
The carburetor has been calibrated to provide lean air/fuel
mixture characteristics and optimum fuel economy with a
suitable air cleaner and exhaust system.
