For maximum performance, the spark arrester screen should be periodically cleaned as follows. See Figure 16. 1. Remove engine cover to expose muffler. Remove the spark arrester from the muffler. The arrester is press-fit in place; there are three screws to remove. 2. Use a plastic scraper or wire brush to remove carbon deposits from the arrester screen and wipe clean exhaust base. 3. Inspect the screen carefully, and replace any screen that has been perforated, distorted, or is otherwise unserviceable. 4. Press the spark arrester into the exhaust base. If carbon accumulation in the muffler or cylinder are severe, or if you do not notice an improvement in performance after servicing, have the unit inspected by an authorized servicing Shindaiwa dealer. Arrester Screen Cover Arrester Screen Muffler Figure 16 Long Term Storage Whenever the unit will not be used for 30 days or longer, use the following procedures to prepare it for storage: n Clean external parts thoroughly. n Drain all the fuel from the fuel tank. IMPORTANT! All stored fuels should be stabilized with a fuel stabilizer such as STA-BIL™ if Shindaiwa One oil with fuel stabilizer is not used. To remove the remaining fuel from the fuel lines and carburetor and with the fuel drained from the fuel tank. 1. Prime the primer bulb until no more fuel is passing through. 2. Start and run the engine until it stops running. 3. Repeat steps 1 and 2 until the engine will no longer start. n Remove the spark plug and pour about 10 cm3 (1/4 oz.) of 2-cycle mixing oil into the cylinder through the spark plug hole. Slowly pull the recoil starter 2 or 3 times so oil will evenly coat the interior of the engine. Reinstall the spark plug. n Before storing the unit, repair or replace any worn or damaged parts. n Remove the air cleaner element from the unit and clean it as outlined on page 10. n Store the unit in a clean, dust-free area. CAUTION! Gasoline stored in the carburetor for extended periods can cause hard starting, and could also lead to increased service and maintenance costs.
