It is highly recommended that this is done by a Shindaiwa-trained service technician. ¦ 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 mm. IMPORTANT! 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! ¦ Performing a valve adjustment incorrectly may cause hard starting and/or can damage the engine. ¦ If you are unfamiliar with this engine or uncomfortable with this procedure, consult with an authorized Shindaiwa servicing dealer. 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. 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) Spark Arrester Screen Maintenance If the engine becomes sluggish and low on power, check and clean the spark arrester screen. WARNING! Never operate the unit with a damaged or missing muffler or spark arrester! Operating with a missing or damaged spark arrester is a fire hazard and could also damage your hearing. 1. With a 3 mm hex wrench remove the 4 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 Shindaiwa servicing dealer.

During the break-in period your engine performance will increase and exhaust emissions will stabilize. Idle speed can be adjusted as required. High Altitude Operation This engine has been factory adjusted to maintain satisfactory starting, emission, and durability performance up to 1,100 feet above sea level (ASL) (96.0 kPa). To maintain proper engine operation and emission compliance above 1,100 feet ASL the carburetor may need to be adjusted by an authorized Shindaiwa service dealer. IMPORTANT! NOTE: If the engine is adjusted for operation above 1,100 feet Every unit is run at the factory and the carburetor is set in ASL, the carburetor must be re-adjusted when operat-compliance with emission regulations. Carburetor adjusting the engine below 1,100 feet ASL, otherwise severe ments, other than idle speed, must be performed by an engine damage may result. authorized Shindaiwa dealer. Maintenance (continued) Adjusting Engine Idle Adjusting Engine Idle The engine must return to idle speed whenever the throttle lever is released. Idle speed is adjustable, and must be set low enough to permit the engine clutch to disengage the cutting attachment. Idle Speed Adjustment 1. Place the unit on the ground, then start the engine, and then allow it to idle 2-3 minutes until warm. 2. If the attachment rotates when the engine is at idle, reduce the idle speed by turning the idle adjustment screw counter-clockwise. 3. If a tachometer is available, adjust idle. Check Specifications page for correct idle speed. Replacing the Edger Blade WARNING! The cutting attachment must NEVER rotate at engine idle! If the idle speed cannot be adjusted by the procedure described here, return the unit to your Shindaiwa dealer for inspection. NOTE Carburetor fuel mixture adjustments are preset at factory and cannot be serviced in the field. Idle Ajust- ment Screw WARNING! Always wear gloves when handling the edger blade. 1.
