Use only BPR6ES (NGK) type spark plug or equivalent. Using an 
incorrect spark plug may damage the engine.
5. When installing a new spark plug, adjust the plug's gap to the 
specication on the Specications Chart. Do not pry against 
the center electrode, the spark plug can be damaged.
6. Apply anti-seize material to Spark Plug threads. Install the 
new spark plug or the cleaned spark plug into the engine.
● Finger-tighten until the gasket contacts the cylinder head, then 
tighten about 3/4 turn more.
Tighten the Spark Plug properly. If loose, the Spark Plug will 
cause the engine to overheat. If over tightened, the threads in 
the engine block will get damaged.
7. Apply dielectric spark plug boot protector (not included) to the 
end of the spark plug and reattach the boot securely.
8. Replace Spark Plug Access Cover and Access Panel.
Storage
When the equipment is to remain idle for longer than 20 days, 
prepare the engine for storage as follows:
1. CLEANING:
Wait for the engine to cool, then clean the engine with a dry cloth.
Do not clean using water. The water will gradually enter the 
engine and cause damage.
2.FUEL:
Gasoline Treatment/Draining the Fuel Tank 
To protect the fuel tank during storage, ll the tank with fresh 
gasoline that has been treated with a fuel stabilizer additive. 
Follow fuel stabilizer manufacturer's recommendations for use.
Fill tank in a well-ventilated area away from ignition sources. If the 
engine is hot from use, shut the engine off and wait for it to cool 
before adding fuel. Do not smoke.
Draining the Carburetor
After closing the Fuel Valve, place an appropriate container under the 
Carburetor and carefully remove the Drain Bolt from the bottom of the 
Carburetor Bowl, allowing the fuel to drain completely. Replace the 
Drain Bolt after draining.
Aged gasoline that has not been treated with stabilizer ahead of time 
must be safely drained and disposed of, never run old gasoline through 
the engine.
3.  LUBRICATION:
a. Change engine oil.
b. Clean out the area around the spark plug.  Remove the spark 
plug and pour one tablespoon of engine oil into the cylinder 
through the spark plug hole.
c. Replace spark plug, but leave spark plug cap disconnected.
d. Pull Starter Handle to distribute oil in the cylinder.  Stop after 
one or two revolutions when you feel the piston start the 
compression stroke (when you start to feel resistance).
4.  STORAGE AREA: 
Cover and store in a dry, level, well-ventilated area out of reach 
of children.  The storage area should also be away from ignition 
sources, such as water heaters, clothes dryers, and furnaces.
To prevent serious injury and re, close the Fuel Valve before 
draining the Carburetor.
During extended storage periods the engine must be started 
every 3 months and allowed to run for 15-20 minutes.
5. AFTER STORAGE:
Untreated gasoline will deteriorate quickly. Drain the fuel tank and 
change to fresh fuel if untreated gasoline has been sitting for a month, 
if treated gasoline has been stored beyond the fuel stabilizer's 
recommended time, or if the engine does not start.
