WARNING
TO PREVENT SERIOUS INJURY FROM
ACCIDENTAL STARTING TURN THE POWER
SWITCH OF THE ENGINE TO ITS “OFF” POSITION.
Wait for the engine to cool, and remove the spark plug wire
before performing any inspection, maintenance, or cleaning.
Changing /Cleaning the Air Filter
1. Remove the wing nut from the air cleaner cover, and remove the air cleaner cover.
2. Remove the wing nut from the air filter, and remove the filter.
3. Remove the foam filter from the paper filter.
4. Inspect both air filter elements, and replace them if they are damaged. Always replace the paper air filter element at the scheduled interval.
5. Clean the air filter elements if they are to be reused.
Paper Air Filter
Tap the filter element several times on a hard surface to remove dirt, or blow compressed air not exceeding 30 psi through the filter element from the inside. Never try to brush off dirt; brushing will force dirt into the fibers.
Foam Air Filter
Clean in warm soapy water, rinse, and allow drying thoroughly. Or clean in nonflammable solvent and allow drying. Dip the filter element in clean engine oil, and then squeeze out all excess oil. e engine will smoke when started if too much oil is left in the foam.
6. Wipe dirt from the inside of the air cleaner base and cover, using a moist rag. Be careful to prevent dirt from entering the air duct that leads to the carburetor.
7. Place the foam air filter element over the paper element, and reinstall the assembled air filter. Be sure the gasket is in place beneath the air filter. Tighten the air filter wing nut securely.
8. Install the air cleaner cover, and tighten the cover wing nut securely.

Maintenance
Spark Plug Maintenance:
1. Disconnect spark plug wire from end of plug. Clean out debris from around the spark plug.
2. Using the spark plug wrench provided, remove the spark plug. Inspect the spark plug. If the electrode is oily, clean it using a clean, dry rag. If the electrode has deposits on it, polish it using emery paper. If the white insulator is cracked or chipped, replace the spark plug.
3. When installing a new spark plug, adjust the plug’s gap to the specication on the technical specication chart. Do not pry against the electrode or the insulator, the spark plug can be damaged (see Figure 6). A recommended spark plug replacement is F7RTC or other equivalent.
4. Install the new spark plug or the cleaned spark plug into the engine. Gasket style spark plugs should be nger-tightened until the gasket contacts the cylinder head, then turned about 1/2 to 2/3 more rotation. Non-gasket-style spark plugs should be nger-tightened until the plug contacts the head, then about 1/16 turn more.

Storage
Draining the Carburetor
1. Let the engine to cool and clean the engine with a cloth.
2. When the engine is to be stored for longer than 20 days, prepare it for storage by emptying the fuel tank and draining all fuel lines (see Figure 9). Clean out area around spark plug and remove. Pour one tablespoon of engine oil into the cylinder through the spark plug hole. Reinstall the spark plug, but leave the spark plug wire disconnected. Pull recoil 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).
3. Apply a thin coat of rust preventive oil to all uncoated metal parts.
4. Cover and store in a dry, well-ventilated area out of reach of children.
Adding a Fuel Stabilizer
An alternative to draining the carburetor for storage is to add fresh gasoline and a fuel stabilizer to the gasoline tank. When adding a fuel stabilizer, fill the fuel tank with fresh gasoline. If only partially filled, air in the tank will promote fuel deterioration during storage.
1. Add fuel stabilizer following the manufacturer’s instructions.
2. After adding a fuel stabilizer, run the engine outdoors for 10 minutes to be sure that treated gasoline has replaced the untreated gasoline in the carburetor.
3. Stop the engine, and move the fuel valve to the OFF position.
!
CAUTION
If your engine will be stored with gasoline in the fuel tank and carburetor, it is important to reduce the hazard of gasoline vapor ignition. Select a well-ventilated storage area away from any appliance that operates with a flame, such as a furnace, water heater, or clothes dryer. Also avoid any area with a spark-producing electric motor, or where power tools are operated. Leave the fuel valve in the OFF position to reduce the possibility of fuel leakage. Position the equipment so the engine is level to avoid fuel or oil leakage.
