The line is delicate and can be damaged easily. Before reinstalling the new filter element, inspect the condition of all the fuel system components (fuel pick-up line, fuel return line, tank vent line, tank vent, fuel cap and fuel tank). If damage, splitting or deterioration is noted, the unit should be removed from service until it can be inspected or repaired by a Shindaiwatrained service technician. 139/150-Hour Maintenance ................................................................................ Hooked wire Maintenance after first 139-hours, then every 150-hours thereafter. Y Combustion chamber should be decarbonized, and the valve clearance should be adjusted. It is highly recommended that this is done by a Shindaiwa-trained service technician. Valve Adjustment 1. Remove cylinder cover, rocker arm cover, and spark plug. Rotate the crankshaft while observing the piston through the spark plug opening. When the piston is at the top of the compression stroke (TDC), the valves can be adjusted. CAUTION! Y Performing a valve adjustment incorrectly may cause hard starting and/or can damage the engine. Y If you are unfamiliar with this engine or uncomfortable with this procedure, consult with an authorized Shindaiwa servicing dealer. Y Replace the spark plug annually: Use only the type recommended in the ”Specifications” section or an equivalent resistor type spark plug of the correct heat range. Set spark plug electrode gap to 0.6 -0.7 mm. 2. Loosen adjuster locknut so that the 2.5 mm Allen socket head adjustment screw can turn freely. 3. Insert 0.10 mm feeler gauge between valve stem tip and rocker arm. 4. Turn adjustment screw (clockwise = tighter, counter-clockwise = looser) until feeler gauge is almost snug. Back off just enough to allow gauge to slip out with limited resistance. 5. While holding the adjustment screw in place with the Allen driver, tighten the locknut with a wrench. Y The valve clearance should be adjusted annually or every 135 hours. It is highly recommended that this is done by a Shindaiwa-trained service technician. 6. Turn engine over several times, and returnthe to TDC-compression. Recheck with proper feeler gauge to make sure clearance adjustment did not change as a result of tightening the locknut. Readjust as necessary. 7. Replace rocker arm cover gasket to assure proper sealing and install cover. IMPORTANT! If a new gasket is not available and/or the old gasket is not damaged, the old gasket may be reused. Never use cracked or damaged gaskets! Maintenance (continued) ........................................................................H If the engine becomes sluggish and low on power, check and clean the spark arrester screen. WARNING! Never operate the unit with a .................................................................. arrester! Operating with a missing or ............................................................................ and could also damage your hearing. 1. With a 3 mm hex wrench remove the engine cover screws and the engine cover. 2. With a 4 mm hex wrench, remove the 3 muffler bolts and the muffler. 3. With a small flat bladed screwdriver remove the 2 screws holding the spark arrester screen and cover to the muffler. 4. Remove the screen and clean it with a stiff bristle brush. 5. Inspect the cylinder exhaust port for any carbon buildup. 6. Reassemble the spark arrester, muffler and engine cover in the reverse order of disassembly. IMPORTANT! If you note excessive carbon buildup, consult with an authorized servicing dealer. Long Term Storage Whenever the unit will not be used for 30 days or longer, use the following procedures to prepare it for storage: Y Clean external parts thoroughly. Y Drain all the fuel from the carburetor and the fuel tank. To do so: 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. Engine Cover Screws Engine Cover .................................................................. Spark Arrester Screen Spark Arrester Cover Cover Screws CAUTION! Gasoline stored in the carburetor for extended periods can cause hard start- ing, and could also lead to increased service and maintenance costs. IMPORTANT! All stored fuels should be stabilized with a fuel stabilizer such as STA-BIL. NOTE Damage caused by stale or contaminated fuel is not covered by the Shindaiwa warranty policy. Y Remove the spark plug and pour about 7 mL (.25 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. Y Before storing the unit, repair or replace any worn or damaged parts. Y Remove the air cleaner element from the carburetor and clean it thoroughly with soap and water, let dry and reassemble the element. Y Store the unit in a clean, dust-free area.
