How do I start the Stihl BR 340/BR 380 blower?

To start the Stihl BR 340/BR 380, first ensure the stop switch is in the 'I' (run) position. Set the choke to the closed position if the engine is cold. Pull the starter rope until you feel resistance, then give it a strong pull. Once the engine fires, open the choke.

What type of fuel should I use for my Stihl BR 340/BR 380?

Use a high-octane, unleaded gasoline mixed with high-quality 2-stroke engine oil in a 50:1 ratio. This ensures optimal performance and longevity of the engine.

How can I troubleshoot if my blower won't start?

Check the fuel level and ensure fresh, properly mixed fuel is used. Inspect the spark plug for wear or damage and replace if necessary. Also, check the air filter for clogs or dirt.

Why is my Stihl blower vibrating excessively?

Excessive vibration could be caused by a damaged impeller or fan. Inspect these components for damage or imbalance. Additionally, make sure all screws and mounts are securely fastened.

How often should I clean the air filter on my BR 340/BR 380?

Clean the air filter after every 10 hours of operation or more frequently if operating in extremely dusty conditions. Replace it if it shows signs of wear or damage.

What should I do if the engine is running but the blower is not producing air?

Inspect the blower tube and fan for blockages. Ensure the throttle is engaged properly. Also, check for any mechanical failure in the fan or drive system.

How do I maintain the spark plug on my Stihl blower?

Inspect the spark plug every 25 hours of operation. Clean it with a wire brush and check the electrode gap, which should be 0.5 mm. Replace the spark plug if it's damaged or worn.

What are the signs of a clogged fuel filter?

Signs of a clogged fuel filter include difficulty starting the engine, erratic engine performance, and decreased power. Replace the fuel filter regularly to prevent these issues.

How can I tell if the carburetor needs adjustment?

If the engine is stalling, idling roughly, or not reaching full power, the carburetor may need adjustment. Refer to the user manual for specific instructions on adjusting the carburetor settings.

What is the proper way to store the blower during the off-season?

Empty the fuel tank and run the engine until it stops to clear the carburetor. Clean the blower thoroughly and store it in a dry, dust-free place. Consider using a cover to protect it from dirt and debris.
