Understanding the Stihl BR600
The BR600 features a 64.8 cc 2‑stroke engine that delivers up to 712 CFM (cubic feet per minute) of air volume at 238 mph. Its anti‑vibration system reduces operator fatigue, while the adjustable harness distributes weight evenly across the shoulders and hips. The blower uses a primer bulb, choke lever, and a decompression valve to simplify starting. Familiarity with these components is essential before you attempt to fire the engine.
Key components include:
- Primer bulb – draws fuel into the carburetor for a richer mixture during cold starts.
- Choke lever – restricts air intake to enrich the mixture further when the engine is cold.
- Decompression valve – lowers compression temporarily, making the pull‑start easier.
- Throttle trigger – controls engine speed once the blower is running.
- Fuel tank – holds a 50:1 gasoline‑to‑oil mixture; always use fresh fuel.
Safety Precautions Before Starting
Safety is the first step in any equipment operation. Follow these precautions every time you prepare the BR600:
- Wear hearing protection, safety glasses, and a dust mask.
- Inspect the harness for frayed straps or broken buckles; replace if damaged.
- Check the fuel system for leaks; tighten the fuel cap securely.
- Clear the work area of bystanders, pets, and flammable materials.
- Ensure the blower is on a stable, level surface before pulling the starter rope.
- Never operate the blower in enclosed spaces; exhaust contains carbon monoxide.
Adhering to these rules reduces the risk of injury and prevents damage to the machine.
Required Tools and Materials
Gather the following items before you begin the starting routine:
- Fresh 50:1 pre‑mixed fuel (or mix your own with high‑quality 2‑stroke oil).
- Clean, lint‑free cloth for wiping the spark plug and air filter.
- Spark plug wrench (usually 13 mm) for inspection or replacement.
- Small screwdriver for adjusting the idle screw if needed.
- Owner’s manual for reference to torque specifications and service intervals.
Having everything at hand eliminates interruptions and ensures a smooth start.
Step‑by‑Step Starting Procedure
Follow this ordered sequence each time you need to start the BR600. The steps assume a cold engine; adjustments for a warm engine are covered in the next section.
- Position the blower – Place the unit on the ground, harness straps loosened, and ensure the throttle trigger is in the idle position.
- Open the fuel valve – Turn the fuel valve lever to the “ON” position; verify fuel flows by gently squeezing the primer bulb until fuel appears.
- Set the choke – Move the choke lever to the full choke position (usually marked “C” or “Full”).
- Press the primer bulb – Pump the primer bulb 5–7 times until you see fuel in the bulb. This primes the carburetor.
- Engage the decompression valve – Push the decompression valve button (often a red button) down; it will stay depressed.
- Grip the starter handle – Hold the starter handle firmly with your dominant hand, keeping the other hand on the blower frame for stability.
- Pull the starter rope – Pull the rope briskly until you feel resistance, then give a strong, smooth pull. Repeat up to three times.
- Release the decompression valve – Once the engine fires, let the decompression valve return to its original position.
- Adjust the choke – As the engine runs, gradually move the choke lever to the “Run” position (often marked “R” or “Open”).
- Allow warm‑up – Let the engine idle for 30–60 seconds before applying full throttle.
If the engine does not start after three pulls, return to step 3 and verify choke and primer settings before trying again.
Cold Start vs Warm Start
A cold start requires the full choke and primer routine described above. A warm start (engine has been run within the last 10–15 minutes) needs less enrichment: (See Also:How To Get Red Science In Leaf Blower Revolution)
- Set the choke to the half‑choke or “Run” position.
- Press the primer bulb only 2–3 times.
- Depress the decompression valve, pull the starter rope once or twice.
- Release the decompression valve and allow the engine to settle.
Using the correct procedure for the engine temperature prevents flooding and reduces wear on the starter mechanism.
Troubleshooting Common Starting Issues
Even a well‑maintained BR600 can refuse to start. The table below lists frequent symptoms, likely causes, and corrective actions.
| Symptom | Possible Cause | Remedy |
|---|---|---|
| Engine cranks but won’t fire | Stale or incorrect fuel mixture | Drain tank, refill with fresh 50:1 mix |
| Engine fires then dies immediately | Clogged air filter or dirty spark plug | Clean or replace air filter; inspect and clean spark plug |
| Hard pull on starter rope | Decompression valve not engaged or seized piston | Ensure valve is depressed; if still hard, service piston rings |
| Excessive smoke on start | Over‑rich mixture (too much oil) | Verify 50:1 ratio; adjust oil amount |
| No fuel in primer bulb | Fuel line blockage or empty tank | Check fuel lines for kinks; refill tank |
If the problem persists after these checks, consult an authorized Stihl service dealer.
Maintenance Tips for Reliable Starts
Regular maintenance is the backbone of dependable starting. Incorporate these tasks into your routine:
- Daily – Wipe the exterior, check for loose bolts, and verify the harness is secure.
- Every 25 hours – Clean the air filter; replace if torn or excessively dirty.
- Every 50 hours – Inspect the spark plug; clean carbon deposits or replace if the electrode is worn.
- Every 100 hours – Replace the fuel filter and inspect fuel lines for cracks.
- Seasonally – Drain old fuel, run the engine dry, and store the blower in a dry, ventilated area.
Keeping a maintenance log helps you track intervals and anticipate parts replacement before a failure occurs.

- Store the unit with the fuel valve off and the tank empty if it will sit unused for more than 30 days.
- Periodically check the anti‑vibration mounts for cracks; replace them to maintain operator comfort.
- Keep the cooling fins clean; debris buildup reduces airflow and raises engine temperature.
Consistent care translates into fewer breakdowns and lower total cost of ownership. (See Also:How To Take Apart A Black And Decker Leaf Blower)
Common Mistakes to Avoid
Even experienced operators can fall into habits that compromise starting reliability:
- Skipping the primer bulb – Leads to a lean mixture and hard starts.
- Leaving the choke on too long – Floods the engine, causing sputtering and excess smoke.
- Using automotive gasoline without oil – Destroys the 2‑stroke engine quickly.
- Pulling the starter rope at an angle – Increases wear on the recoil spring and can snap the rope.
- Neglecting the air filter – Allows dirt into the carburetor, resulting in poor performance.
Awareness of these pitfalls helps you develop a smooth, repeatable starting routine.
Frequently Asked Questions
How often should I replace the spark plug on a Stihl BR600?
Inspect the spark plug every 50 hours of operation. Replace it if the electrode is worn, the insulator is cracked, or carbon buildup cannot be cleaned off. A fresh plug ensures reliable ignition and easier starts.
Can I use ethanol‑blended gasoline in the BR600?
Stihl recommends fuel with no more than 10 % ethanol (E10). Higher ethanol blends can attract moisture, cause phase separation, and damage the carburetor. Use fresh fuel and add a fuel stabilizer if the blower will sit idle for weeks.
What is the correct 50:1 fuel‑to‑oil ratio for the BR600?
Mix 2.6 oz (77 ml) of high‑quality 2‑stroke oil per gallon (3.78 L) of gasoline. Measure accurately; an incorrect ratio leads to either excessive smoke or insufficient lubrication.
Why does my BR600 stall when I engage the throttle?
Stalling under load often indicates a dirty air filter, a clogged fuel filter, or an idle speed set too low. Clean the filters first, then adjust the idle screw per the manual until the engine holds a steady idle before applying throttle. (See Also:How To Change Spark Plug On Stihl Leaf Blower)
Is it necessary to run the blower dry before long‑term storage?
Yes. Running the engine until it stops from fuel starvation removes residual gasoline from the carburetor, preventing gum formation. Afterward, store the blower in a cool, dry place with the fuel valve closed.
How do I know if the decompression valve is working?
When you press the decompression valve, you should feel a distinct click and the starter rope should pull noticeably easier. If the rope remains stiff, the valve may be stuck or the internal spring broken; service the valve before further use.
