Every 135 hours of operation, remove 

and clean the muffler.

 WARNING!

damaged or missing muffler or spark 

arrester! Operating with missing or 

damaged exhaust components is a fire

hearing.

2.  Remove the two 4 mm engine cover 

screws (located at the top of the recoil 

housing).

3.  Loosen the 5 mm engine top cover

6.  Remove the spark arrester screen and 

clean with a stiff bristle brush.

7.  Gently tap the muffler on a wood surface

carbon buildup. 

IMPORTANT!

If you note excessive carbon buildup, con-

sult with an authorized servicing dealer.

Long Term Storage

Whenever the unit will not be used for 30 

days or longer, use the following proce-

dures to prepare it for storage:


  Clean external parts thoroughly and 

apply a light coating of oil to all metal 

surfaces.



  Drain all the fuel from the fuel tank.

IMPORTANT!

All stored fuels should be stabilized with 

a fuel stabilizer such as STA-BIL™, if             

oil with fuel stabilizer is not used.

To remove the remaining fuel from the 

fuel lines and carburetor and with the fuel 

drained from the fuel tank. 



  Remove the spark plug and pour about 

1/4 ounce of 2-cycle mixing oil into the 

cylinder through the spark plug hole. 

Slowly pull the recoil starter 2 or 3 times 

so oil will evenly coat the interior of the 

engine. Reinstall the spark plug.



  Before storing the unit, repair or replace 

any worn or damaged parts.



  Remove the air cleaner element from the 

carburetor and clean it thoroughly with 

soap and water. Let dry and reassemble 

the element.



  Store the unit in a clean, dust-free area.

CAUTION!
Gasoline stored in the carburetor for 

extended periods can cause hard start-

ing, and could also lead to increased 

service and maintenance costs.

1.  Prime the primer bulb until no more fuel 

is passing through.

2.  Start and run the engine until stops  

running.

3.  Repeat steps 1 and 2 until the engine will 

no longer start.
