The EB808 is a powerful two-stroke, air-cooled backpack blower designed for various outdoor tasks, including clearing fallen leaves, snow removal, road cleaning, dust removal, and even assisting in forest fire fighting efforts.
2. Safety Information
2.1 General Safety Precautions
- Always wear appropriate personal protective equipment (PPE), including eye protection, hearing protection, gloves, and sturdy footwear.
- Do not operate the blower in enclosed spaces due to exhaust fumes.
- Keep children, bystanders, and pets at a safe distance (at least 15 meters / 50 feet) from the operating area.
- Inspect the work area for objects that could be thrown or entangled in the blower.
- Never point the blower nozzle at people or animals.
- Ensure all connections are secure before starting the engine.
2.2 Fuel Safety
- Gasoline is highly flammable. Handle fuel with extreme care.
- Mix fuel in a well-ventilated area, away from sparks or open flames.
- Use a clean, approved fuel container.
- Do not smoke while handling fuel.
- Wipe up any spilled fuel immediately.
- Store fuel in a cool, dry place, away from heat sources.
3. Product Components
Familiarize yourself with the main components of your EB808 Backpack Gas Leaf Blower:

- Main Engine Unit (with fuel tank and air filter housing)
- Backpack Harness
- Flexible Blower Tube
- Rigid Blower Tubes (multiple sections)
- Nozzle (flat or round, depending on model)
- Control Handle (with throttle and cruise control)
- Spark Plug Wrench
- Fuel Mixing Bottle (if included)
4. Assembly Instructions
Follow these steps to assemble your EB808 Leaf Blower:
- Attach the Flexible Tube: Secure the flexible blower tube to the outlet on the main engine unit using the provided clamp. Ensure a tight fit to prevent air leaks.
- Connect Rigid Tubes: Connect the rigid blower tube sections together. The EB808 features a four-section segmented coupling type for tool-free connection. Push and twist until secure.
- Attach Nozzle: Secure the desired nozzle (e.g., flat or round) to the end of the rigid blower tube.
- Mount Control Handle: Attach the control handle to the flexible or rigid tube at a comfortable operating position. Tighten any fasteners to secure it.
- Adjust Backpack Harness: Adjust the shoulder straps and waist belt of the backpack harness for a comfortable and secure fit. The padded design helps with long-term work.

5. Fueling and Starting the Engine
5.1 Fuel Mixture
The EB808 uses a two-stroke engine and requires a specific mixture of unleaded gasoline and two-stroke engine oil. Refer to your engine oil's instructions for the correct mixing ratio (commonly 25:1 or 50:1, but always verify). Use fresh, high-quality unleaded gasoline with an octane rating of 89 or higher.
- Mix the gasoline and two-stroke oil in an approved fuel container.
- Shake the container thoroughly to ensure proper mixing.
- Carefully pour the mixed fuel into the blower's fuel tank (Tank capacity: 1.2L), avoiding overfilling.
- Securely close the fuel cap.
5.2 Starting Procedure
- Place the blower on a flat, stable surface.
- Ensure the ON/OFF switch is in the "ON" position.
- Move the choke lever to the "CLOSED" (cold start) position.
- Press the primer bulb several times until fuel is visible in the return line.
- Pull the starter cord firmly and smoothly until the engine attempts to start (usually 3-5 pulls).
- Once the engine "pops" or attempts to start, move the choke lever to the "OPEN" (run) position.
- Pull the starter cord again until the engine starts.
- Allow the engine to warm up for a few moments before applying full throttle.
- To stop the engine, move the ON/OFF switch to the "OFF" position.
6. Operating the Blower
Once the engine is running and warmed up, you can begin operation.
- Put on the backpack blower, ensuring the harness is snug and comfortable.
- Hold the control handle firmly. The constant speed cruise handle allows for stable output and reduces fatigue during long-term work.
- Gradually increase the throttle to achieve the desired blowing force.
- Sweep the blower nozzle from side to side to move debris effectively.
- For heavy or wet debris, use a lower angle to lift and move the material.
6.1 Applications
- Leaf Clearing: Efficiently gather and move dry or wet leaves from lawns, driveways, and pathways.
- Snow Removal: Clear light, powdery snow from sidewalks and small areas.
- Road/Site Cleaning: Remove dust, debris, and light construction slag from surfaces.
- Forest Fire Fighting: Can be used to create firebreaks by blowing away combustible ground cover (requires specialized training and safety protocols).
7. Maintenance
Regular maintenance ensures optimal performance and extends the life of your blower.
7.1 After Each Use
- Clean the exterior of the blower, removing any debris, dust, or grass.
- Check for loose fasteners and tighten as necessary.
- Inspect the blower tubes for damage or blockages.
7.2 Every 10 Hours of Operation
- Air Filter: Remove and clean the air filter. If heavily soiled or damaged, replace it. A clean air filter is crucial for engine performance and longevity.
- Spark Plug: Inspect the spark plug for wear, carbon buildup, or damage. Clean or replace as needed. Use the provided spark plug wrench.
7.3 Seasonal Storage
- Drain all fuel from the fuel tank and run the engine until it stops to clear the carburetor. This prevents fuel degradation and carburetor issues.
- Clean the entire unit thoroughly.
- Store the blower in a dry, clean area, away from direct sunlight and extreme temperatures.
8. Troubleshooting
Here are some common issues and their solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Engine won't start | No fuel or incorrect fuel mixture ON/OFF switch in "OFF" position Choke not set correctly Fouled spark plug Clogged air filter | Check fuel level and mixture Move switch to "ON" Adjust choke according to starting procedure Clean or replace spark plug Clean or replace air filter |
| Loss of power during operation | Clogged air filter Incorrect fuel mixture Overheating | Clean or replace air filter Ensure correct fuel/oil ratio Allow engine to cool down; check for obstructions around cooling fins |
| Excessive smoke from exhaust | Too much oil in fuel mixture Wrong type of oil Clogged exhaust port | Use correct fuel/oil ratio Use recommended two-stroke engine oil Consult a service technician |
