2. Safety Information

Always prioritize safety when operating power equipment. Failure to follow these safety instructions may result in serious injury or property damage.

• Read the Manual: Understand all instructions and warnings before use.
• Personal Protective Equipment (PPE): Always wear eye protection (safety glasses or goggles), hearing protection, long pants, sturdy footwear, and gloves.
• Fuel Handling: Handle gasoline with extreme care. It is highly flammable. Store fuel in approved containers, away from ignition sources. Refuel outdoors in a well-ventilated area with the engine off and cool.
• Ventilation: Operate the blower in well-ventilated outdoor areas only. Exhaust fumes contain carbon monoxide, which is a colorless, odorless, and deadly gas.
• Clear Work Area: Keep children, bystanders, and pets at a safe distance (at least 50 feet/15 meters) from the operating area. Inspect the area for debris that could be thrown by the air stream.
• Secure Grip: Maintain a firm grip on the control handle during operation.
• Avoid Loose Clothing: Do not wear loose clothing, scarves, or jewelry that could get caught in moving parts.
• Inspect Before Use: Before each use, check for loose fasteners, damaged parts, or fuel leaks. Do not operate if damaged.
• Emergency Stop: Familiarize yourself with the location and operation of the engine stop switch.

5. Assembly

Follow these steps to assemble your leaf blower:

1. Attach Flexible Hose: Connect the flexible blower hose to the outlet on the main blower unit. Secure it with the provided hose clamp.
2. Assemble Blower Tube: Connect the various sections of the blower tube together. Ensure they are firmly seated.
3. Attach Control Handle: Slide the control handle assembly onto the blower tube and secure it at a comfortable operating position. Tighten any fasteners to prevent rotation.
4. Connect Throttle Cable: Connect the throttle cable from the control handle to the carburetor on the engine, ensuring smooth operation of the throttle trigger.

6. Fuel Mixture

This leaf blower uses a 2-stroke engine and requires a specific gasoline-to-oil mixture. Do not use straight gasoline or automotive oil.

• Mixing Ratio: The recommended fuel mixture ratio is 25:1 (Gasoline to 2-Stroke Engine Oil).
• Fuel Type: Use fresh, unleaded gasoline with an octane rating of 89 or higher.
• Oil Type: Use high-quality 2-stroke engine oil specifically designed for air-cooled engines.
• Mixing Procedure:
  1. Pour the correct amount of 2-stroke oil into the fuel mixing bottle.
  2. Add the corresponding amount of gasoline.
  3. Securely close the bottle and shake it vigorously to ensure thorough mixing.
  4. Always mix fuel in a well-ventilated area, away from sparks or open flames.
• Filling the Tank: With the engine off and cool, carefully pour the mixed fuel into the blower's fuel tank using the provided funnel. Do not overfill.

7. Starting Procedure

Follow these steps to start your Ebikestar 72CC Gas Backpack Leaf Blower:

1. Fuel Primer Bulb: Before each start, press the fuel primer bulb 6-7 times until fuel is visible in the bulb and lines. This supplies fuel to the carburetor.
2. Choke Control: For a cold engine, move the choke control lever to the 'CLOSED' (or 'START') position. For a warm engine, the choke may not be necessary or can be set to 'OPEN' (or 'RUN').
3. Ignition Switch: Ensure the ignition switch is in the 'ON' position.
4. Starting Pull: Place the blower on a flat, stable surface. Hold the unit firmly with one hand and pull the starter handle slowly until resistance is felt, then pull sharply 5-8 times. The engine should fire or attempt to start.
5. Open Choke: Once the engine fires or starts briefly, immediately move the choke control lever to the 'OPEN' (or 'RUN') position.
6. Final Pulls: Pull the starter handle again 1-3 times until the engine starts and runs smoothly.
7. Warm-up: Allow the engine to warm up for a few moments before applying full throttle.

Important Note: If the engine runs out of fuel during operation, it may be difficult to restart immediately after refueling. Allow the engine to cool down for a period before attempting to restart, and ensure the primer bulb is fully primed.

8. Operating Instructions

Once the engine is running, you can begin operation.

• Wearing the Blower: Adjust the backpack straps for a comfortable and secure fit. The weight should be evenly distributed across your shoulders and back to reduce fatigue.
• Throttle Control: Use the throttle trigger on the control handle to increase or decrease engine speed and airflow.
• Cruise Control: For extended periods of blowing at a consistent speed, engage the cruise control feature. This allows you to release the throttle trigger while maintaining the desired engine RPM, reducing hand fatigue.
• Blowing Technique: Sweep the blower tube from side to side, moving debris in front of you. Avoid directing the air stream at people, animals, or fragile objects.
• Applications: This blower is suitable for clearing leaves, grass clippings, light snow, dust, and other loose debris from various surfaces such as lawns, driveways, patios, and construction sites.

9. Maintenance

Regular maintenance ensures optimal performance and extends the life of your leaf blower.

• Air Filter: Check and clean the air filter regularly (every 5-10 hours of operation, or more frequently in dusty conditions). Remove the filter cover, clean the filter element with warm, soapy water, rinse thoroughly, and allow it to dry completely before reinstallation. Replace if damaged.
• Spark Plug: Inspect the spark plug every 20-30 hours of operation. Clean any carbon deposits and check the electrode gap. Replace if worn or fouled. Refer to the specifications for the correct spark plug type and gap.
• Fuel Filter: The fuel filter, located inside the fuel tank, should be checked periodically and replaced if clogged or damaged.
• Cooling Fins: Keep the engine's cooling fins clean and free of debris to prevent overheating.
• General Cleaning: After each use, clean the exterior of the blower with a damp cloth. Remove any accumulated debris from the fan housing and blower tube.
• Fasteners: Periodically check all nuts, bolts, and screws for tightness and tighten as necessary.

12. Storage

Proper storage is crucial for maintaining your leaf blower, especially during off-season periods.

• Short-Term Storage: After each use, allow the engine to cool. Clean the exterior of the blower. Store in a dry, well-ventilated area, away from direct sunlight and heat sources.
• Long-Term Storage (Over 30 days):
  1. Drain Fuel: Run the engine until it runs out of fuel to empty the fuel tank and carburetor. This prevents fuel degradation and gumming.
  2. Clean: Thoroughly clean the entire unit, including the air filter and cooling fins.
  3. Spark Plug: Remove the spark plug and pour a small amount (approx. 1 teaspoon) of 2-stroke engine oil into the cylinder. Pull the starter cord a few times to distribute the oil, then reinstall the spark plug.
  4. Store: Store the blower in a clean, dry, and secure location, out of reach of children.
