Frequently Asked Questions - EB8520RT Shindaiwa
How to start the Shindaiwa EB8520RT blower?
Make sure the switch is set to 'I', then pump the primer bulb 5 to 7 times until you see fuel in the tube. Pull the starter handle slowly until you feel resistance, then pull sharply. If the engine does not start, repeat while slightly opening the choke.
What is the fuel-oil mixture ratio?
The recommended mixture is 50:1 (50 parts unleaded gasoline to 1 part Shindaiwa 2-stroke oil or equivalent). Use a graduated container for precise measurement.
How to adjust the idle speed?
The idle should be adjusted so that the clutch does not engage. Turn the idle screw (usually marked 'T' or 'LA') clockwise to increase speed, counterclockwise to decrease. The fan should stop at idle.
How to clean the air filter?
Remove the filter cover, take out the foam element. Wash it in soapy water, rinse, squeeze dry, and let dry. Lightly soak it in air filter oil, squeeze out excess, and reassemble. Clean every 10 hours of use.
What type of fuel to use?
Use unleaded gasoline with octane rating 95 or higher (E10 max 10% ethanol). Avoid fuels with more than 10% ethanol as they can damage the engine.
What to do if the engine does not rev up?
First check the air filter: if dirty, clean it. Then check the spark plug: replace if black or fouled. Also ensure the main jet is not clogged.
How to store the blower during winter?
Completely drain the fuel tank and run the engine until it stops to empty the carburetor. Clean the cooling fins, air filter, and intake screen. Store the unit in a dry, frost-free place.
What causes difficult starting after storage?
Most often, it is due to degraded residual fuel (gum). Use fresh fuel and drain before storage. If the problem persists, clean the carburetor or replace the gasket kit.
How to replace the spark plug?
Disconnect the spark plug cap, use a spark plug wrench to remove the old one. Check the gap (0.6-0.7 mm). Screw the new one in by hand, then tighten an additional half-turn with the wrench. Replace the cap.
Is it possible to use a blower indoors?
No, indoor use is dangerous due to toxic exhaust gases (carbon monoxide). Always use outdoors in a well-ventilated area.
