   NOTICE: Use only A5RTC type spark plug or equivalent. Using an incorrect spark plug may damage the engine.
6. When installing a new spark plug, adjust the plug's gap to the specification on the Specifications chart. Do not pry against the plug electrode, the spark plug can be damaged.
7. Apply anti-sieze material to Spark Plug threads.
   Install the new spark plug or the cleaned spark plug into the engine.

• Gasket-style: Finger-tighten until the gasket contacts the cylinder head, then tighten about 1/2-2/3 turn more.
• Non-gasket-style: Finger-tighten until the plug contacts the cylinder head, then tighten about 1/16 turn more.

NOTICE: Tighten the spark plug properly.
If loose, the spark plug will cause the engine to overheat.
If overtightened, the threads in the engine block will be damaged.

8. Apply dielectric spark plug boot protector (not included) to the end of the spark plug and reattach the cap securely.
9. 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 engine to cool, then clean engine with dry cloth.
   NOTICE: 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, fill the tank with fresh gasoline that has been treated with a fuel stabilizer additive. Follow fuel stabilizer manufacturer's recommendations for use. Refer to Checking and Filling Fuel.
   Aged gasoline that has not been treated with stabilizer ahead of time must be safely drained away and not run through the engine
   
   
   TO PREVENT SERIOUS INJURY FROM FIRE:
   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.
   
   To prevent serious injury and fire, close the Fuel Valve before draining the Carburetor.
   
3. LUBRICATION:
   1. Change engine oil.
   2. Clean out area around spark plug. Remove spark plug and pour one tablespoon of engine oil into cylinder through spark plug hole.
   3. Replace spark plug, but leave spark plug cap disconnected.
   4. Pull Starter Handle to distribute oil in 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. Storage area should also be away from ignition sources, such as water heaters, clothes dryers, and furnaces.
5. Avoid direct exposure to rain and sunlight.
   NOTICE: During extended storage periods the Engine must be started every 3 months and allowed to run for 15 – 20 minutes or the Warranty is VOID.
6. AFTER STORAGE:
   Before starting the engine after storage, keep in mind that 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 sitting beyond the fuel stabilizer's recommended time period, or if the engine does not start.
