Assembling the Blower WARNING! Danger from rotating impeller! Stop the engine before installing or removing the blower tubes! Never perform any maintenance or assembly procedures on this unit while the engine is running! Push the blower tube over the discharge port and locking pin Place the blower upright on the ground or on a sturdy work surface. 1. Grasp the blower tube as shown, and push the tube over the blower discharge port and locking pins. Locking Pin Blower 1 Tube Rotate clockwise to lock 2.
Mixing Fuel WARNING! Alternative fuels, such as E15 (15% ethanol), E-85 (85% ethanol) or any fuels not meeting Shindaiwa requirements are NOT approved for use in Shindaiwa gasoline engines. Use of alternative fuels may cause performance problems, loss of power, overheating, fuel vapor lock, and unintended machine operation, including, but not limited to, improper clutch engagement. Alternative fuels may also cause premature deterioration of fuel lines, gaskets, carburetors and other engine components.
Mixing Instructions 1. 2. 3. 4. Fill an approved fuel container with half of the required amount of gasoline. Add the proper amount of engine oil to gasoline. Close container and shake to mix oil with gasoline. Add remaining gasoline, close fuel container, and remix. IMPORTANT! Spilled fuel is a leading cause of hydrocarbon emissions. Some states may require the use of automatic fuel shut-off containers to reduce fuel spillage. After use • DO NOT store a unit with fuel in its tank. Leaks can occur.
Starting the Engine (continued) 4. Slide the ignition switch to the “I” (ON) position, then depress the throttle lever half way and lock throttle by moving throttle lock lever halfway down. See Figure 6. Full Throttle Idle Throttle Lock Lever 6. Using your right hand, pull the starter handle slowly until you feel the starter engage. See Figure 7. 7. As the starter engages, pull the starter handle upward rapidly. 8. If necessary, repeat Steps 6 and 7 until the engine starts. When The Engine Starts– 1.
Operating Blower WARNING! Engine exhaust IS HOT, and contains Carbon Monoxide (CO), a poison gas. Breathing CO can cause unconsciousness, serious injury, or death. Exhaust can cause serious burns. ALWAYS position unit so that exhaust is directed away from your face and body. WARNING! Always wear safety glasses, hearing protection and a face filter mask or serious personal injury may result. Do not point the blower pipe in the direction of people or pets.
Throttle Control IMPORTANT! To avoid engine damage due to over-revving do not block blower pipe. 1. Use only during appropriate hours. 2. Control engine speed with throttle lever, or for continuous use, set engine speed with throttle lock lever. 3. Use lower speed to blow debris from hard surfaces. Additional speed may be necessary to clean debris, snow, etc. from lawns and flowerbeds. Note: Never use a higher speed setting than necessary to perform a task.

Air Filter 1. Remove the air cleaner cover by loosening the thumb screw and lifting up. See Figure 13A. Figure 13A Unscrew Fasteners 2. Remove and inspect the pre-filter. If the pre-filter is torn or otherwise damaged, replace it with a new one. See Figure 13B. 3. Clean the pre-filter with soap and water. Let dry before reinstalling. 4. Inspect the air cleaner element. If the element is damaged or distorted, replace it with a new one. See Figure 13B. 5.
Spark Plug CAUTION! Never allow dirt or debris to enter the cylinder bore! Before removing the spark plug, thoroughly clean the spark plug and cylinder head area! Allow the engine to cool before servicing the spark plug! Cylinder threads can be damaged by tightening or loosening the spark plug while the engine is hot! 1. Use the spark plug wrench to remove the spark plug. See Figure 14. 2. Clean and adjust the spark plug gap to 0.6mm (0.024 in.).
Valve Adjustment ■■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. ■■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.
Exhaust System Spark Arrester Maintenance WARNING! Never operate this blower with a damaged or missing muffler or spark arrester! Operating with missing or damaged exhaust components is a fire hazard, and can also damage your hearing! Hard starting or a gradual loss of performance can be caused by carbon deposits lodged in the spark arrester screen. For maximum performance, the spark arrester screen should be periodically cleaned as follows. See Figure 16.
Idle Adjustment Before adjustment make sure that: • Air filter is clean and properly installed. • Spark arrestor screen is free of carbon. Idle Ajustment Screw • Blower pipes are installed. 1. Start engine, run at idle for 2-3 minutes. 2. Check idle speed and reset if necessary. If a tachometer is available, idle speed screw should be set to the specifications found on Page 6 “Specifications” of this manual. Turn idle screw clockwise to increase idle speed; counter clockwise to decrease idle speed.
Troubleshooting Guide ENGINE DOES NOT START OR HARD TO START Possible Cause What To Check Vaporlock. Valve adjustment. Remedy Engine hot/heat soaked. Let cool completely and restart. Low fuel quality. Refill with fresh, clean unleaded gasoline with a pump octane of 89 or higher mixed with an air cooled engine oil that meets or exceeds ISO-L-EGD and/or JASO FD classified oils at 50:1 gasoline/oil ratio. Valve clearance too tight. Consult with an authorized Shindaiwa servicing dealer.
Troubleshooting Guide (continued) LOW POWER OUTPUT What To Check Is the engine overheating? Engine is rough at all speeds. May also have black smoke and/or unburned fuel at the exhaust. Possible Cause Operator is overworking the unit. Use a lower throttle setting. Carburetor mixture is too lean. Consult with an authorized Shindaiwa servicing dealer. Improper fuel ratio.
Troubleshooting Guide (continued) ADDITIONAL PROBLEMS Symptom Poor acceleration. Engine stops abruptly. Possible Cause Clogged air filter. Clean the air filter. Clogged fuel filter. Replace the fuel filter. Lean fuel/air mixture. Consult with an authorized Shindaiwa servicing dealer. Idle speed set too low. Adjust idle. Check Specifications page for correct idle speed. Ignition switch turned off. Reset the switch and re-start. Fuel tank empty.
