Fuel Stabilizer

Gasoline left in the fuel system for extended 

periods without a stabilizer will deteriorate, 

resulting in gum deposits in the system. These 

deposits can damage the carburetor and the 

fuel hoses, filter and tank. Prevent deposits 

from forming in the fuel system during storage 

by adding a quality fuel stabilizer to the fuel. 

Follow the recommended mix ratio found on 

the fuel stabilizer container.

Start Engine

1.  Make sure control lever is in neutral 

position.

2.  Move the engine switch to the ON 

position.

3.  Open the fuel shut-off valve.
4.  Set the choke lever based on engine 

temperature.

5.  Slowly pull the recoil starter until engine 

compression makes pulling difficult. 
Let the starter rewind a little and then 
pull smoothly and quickly to start the 
engine.

6.  Repeat Step 5 as needed.
7.  Fully open the choke and set the throttle 

to full fast before operating the unit.

Stop Engine

1.  Return cylinder to fully retracted 

position.

2.  Move throttle lever to slow position.
3.  Move the engine switch to the OFF.

  CAUTION!  Avoid injury! Explosive 

separation of tire and rim parts is possible 
when they are serviced incorrectly:

•  Do not attempt to mount a tire without 

the proper equipment and experience 
to perform the job.

•  Do not inflate the tires above the 

recommended pressure.

•  Do not weld or heat a wheel and tire 

assembly. Heat can cause an increase 
in air pressure resulting in an explosion. 
Welding can structurally weaken or 
deform the wheel.

•  Do not stand in front or over the tire 

assembly when inflating. Use a clip-on 
chuck and extension hose long enough 
to allow you to stand to one side.
