To start the Stihl BG 50 blower, first ensure the throttle trigger is in the idle position. Set the choke lever to the closed position, and press the fuel pump bulb at least 5 times. Pull the starter rope until the engine fires. Once it fires, move the choke lever to the open position and pull the starter rope again to start the engine.
The Stihl BG 50 blower requires a mixture of unleaded gasoline with a minimum octane rating of 89 and high-quality 2-cycle engine oil at a 50:1 ratio.
It is recommended to clean the air filter after approximately 10 hours of operation, or more frequently in dusty conditions. Regular maintenance will ensure optimal performance and longevity of the blower.
If the blower won't start, check the fuel level and ensure the fuel mixture is correct. Inspect the spark plug for wear or damage and replace if necessary. Also, ensure the air filter is clean and the choke lever is set correctly.
To replace the spark plug, first disconnect the spark plug boot. Use a spark plug wrench to remove the old spark plug. Install the new spark plug by hand to avoid cross-threading, then tighten it with the wrench. Reconnect the spark plug boot securely.
Loss of power can be due to a dirty air filter, clogged fuel filter, or a worn spark plug. Check and clean the air filter, replace the fuel filter if necessary, and inspect the spark plug. Regular maintenance helps prevent power issues.
Before storing for the winter, drain the fuel tank and run the engine until it stops to clear the carburetor. Clean the blower thoroughly and store it in a dry place. Consider removing the spark plug and adding a few drops of oil to the cylinder for extra protection.
To clean the fuel filter, first ensure the engine is off and cool. Remove the fuel cap and use a wire hook to gently pull the fuel filter out of the tank. Clean it with fresh gasoline or replace it if it's excessively dirty or damaged.
Carburetor adjustment should only be performed if necessary. Use a small flathead screwdriver to adjust the L and H screws on the carburetor. Turn the L screw to adjust low-speed performance and the H screw for high-speed. It's recommended to have a professional handle carburetor adjustments if you're unsure.
Routine maintenance includes cleaning the air filter, inspecting and replacing the spark plug as needed, checking the fuel filter, and ensuring all screws and fasteners are tight. Regularly inspect the blower tube and housing for damage.
