wrench to compress the washer.
NOTE: When installing a new spark plug, tighten 1⁄2-turn 

after the spark plug seats to compress the washer. When 

reinstalling a used spark plug, tighten 1⁄8- to 1⁄4-turn after 

the spark plug seats to compress the washer.

The spark plug must be tightened 

securely. A loose spark plug can become very hot 

and can damage the engine.

If the engine has been running, allow it to cool for at least half 

an hour before cleaning. Periodically remove dirt build-up from 

engine. 

Do not spray the engine with water to 

clean it because the water could contaminate the 

fuel. Using a garden hose or pressure washing 

equipment can also force water into the muffler 

opening. Water that passes through the muffler can 

enter the cylinder and cause damage.

Accumulation of debris around the 

muffler could cause a fire. Inspect and clean before 

every use.

Engines stored over 30 days need to be drained of fuel to 

prevent deterioration and gum from forming in the fuel 

system or on essential carburetor parts. If the gasoline in your 

engine deteriorates during storage, you may need to have the 

carburetor, and other fuel system components, serviced or 

replaced.

Remove all fuel from the tank by running the engine until it

furnace, water heater or clothes dryer. Avoid any area with 

a spark producing electric motor, or where power tools are 

operated.
If possible, avoid storage areas with high humidity.
