The Stihl leaf blower model BG55 is a handheld, gas-powered blower built for homeowners who need to clear leaves, grass clippings and light debris from lawns, driveways and patios. This guide explains how to match the BG55 to your yard, start it correctly, run it efficiently and keep it in good working order. Follow the steps below and you should get reliable starts and steady airflow for years of seasonal cleanup.

Confirm the BG55 Fits Your Yard

The BG55 is a lightweight handheld unit, so it suits small to mid-sized yards where you mostly work on flat ground. Before you buy or use one, check that the tool matches your cleanup tasks. Its power is well suited to loose leaves and cut grass, but heavy wet debris packed against fences or in gutters will take longer. For a full overview of its design, see Stihl Leaf Blower BG55 Review: Features and Performance.

Start and Operate the BG55 Safely

Good starting habits prevent flooding and extend engine life. Work through these steps each time:

  1. Place the blower on flat, clear ground and keep your feet clear of the nozzle.
  2. Set the choke to the start position, and press the primer bulb five to ten times until fuel fills it.
  3. Hold the blower firmly with one hand on the handle and the other on the starter grip, then pull smoothly until the engine coughs.
  4. Once it starts, move the choke to run and let the engine idle for a few seconds before you apply throttle.
  5. Use the throttle lock sparingly and always release the throttle fully when you pause.

If the engine floods, set the choke to run, hold the throttle wide open, and pull the starter several times to clear the cylinder. For a step-by-step walkthrough of the same process on a sibling model, see Stihl BG 56 Leaf Blower: Setup, Starting and Care Guide.

Fuel the BG55 Correctly

Stihl specifies a mix of fresh unleaded gasoline and two-stroke engine oil, and the ratio depends on the oil you use. Mix fuel in a clean container, shake it well, and use it within about 30 days. Stale fuel is one of the most common causes of hard starting in stored blowers. Never run the engine indoors or in an enclosed space.

Keep the BG55 Running Well

Regular maintenance keeps airflow strong and starts reliable. Check the air filter after every few uses and clean or replace it when it looks clogged. Inspect the spark plug periodically, and keep the cooling fins free of grass and debris to prevent overheating. Drain fuel or run the tank dry before long storage.

Common Mistakes to Avoid

  • Using old or unmixed fuel, which leads to rough running and carbon buildup.
  • Skipping the air filter check, which starves the engine of air and cuts power.
  • Pulling the starter with the choke in the wrong position, causing repeated flooding.
  • Blowing wet, matted debris without breaking it up first, which strains the engine.
  • Storing the blower with fuel left in the tank, which gums the carburetor.

A few accessories make BG55 use easier and safer.

  • Ear protection helps reduce noise exposure during longer sessions. View on Amazon
  • Safety glasses keep grit and small debris out of your eyes while you blow. View on Amazon
  • A fuel mixing container with clear measurement marks makes the two-stroke ratio easier to get right. View on Amazon

FAQ

What fuel does the Stihl BG55 use?

The BG55 runs on a premixed blend of gasoline and two-stroke engine oil. Check the owner’s manual for the exact ratio that matches your oil.

Why won’t my BG55 start?

The most common causes are stale fuel, a flooded engine, a dirty air filter or a fouled spark plug. Check each of these before assuming a larger fault.

How often should I clean the air filter?

Inspect it after every few uses and clean it whenever it looks dirty or clogged. Replace it if cleaning no longer restores good airflow. For serious repairs, consult an authorized Stihl service dealer.

Conclusion

The Stihl leaf blower model BG55 performs best when you match it to your yard, start it with the correct choke and primer routine, and keep fuel fresh. A few minutes of filter and plug checks each season will keep it dependable. Follow the steps above and your cleanup days will run more smoothly.
