Operating Instructions
1. Starting the Engine
- Place the blower on a flat, stable surface.
- Ensure the fuel tank is filled with the correct fuel mixture.
- Set the ON/OFF switch to the 'ON' position.
- Move the choke lever to the 'CLOSED' (start) position.
- Press the primer bulb 5-7 times until fuel is visible in the return line.
- Pull the starter cord firmly and smoothly until the engine attempts to start (usually 1-3 pulls).
- Once the engine 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 30-60 seconds before applying full throttle.
2. Using the Blower
Once the engine is running and warmed up, put on the backpack and adjust the throttle to the desired blowing power. Direct the nozzle towards the debris you wish to clear. The blower features a shock absorption system for reduced vibration during operation.

3. Stopping the Engine
To stop the engine, release the throttle and allow the engine to idle for a few seconds. Then, move the ON/OFF switch to the 'OFF' position.
Maintenance
Regular maintenance ensures optimal performance and extends the life of your blower. Always disconnect the spark plug wire before performing any maintenance.
1. Spark Plug Check
Periodically inspect the spark plug for wear, carbon buildup, or damage. Clean or replace as necessary. A properly functioning spark plug is crucial for easy starting and efficient engine operation.

2. Air Filter Cleaning
The air filter should be cleaned regularly, especially in dusty conditions. Remove the air filter cover, take out the filter element, and clean it with warm, soapy water. Rinse thoroughly and allow it to dry completely before reinstallation. Replace if damaged.
3. Fuel Filter
Inspect the fuel filter located inside the fuel tank periodically. Replace if it appears clogged or dirty to ensure proper fuel flow to the engine.
4. General Cleaning and Storage
After each use, clean the exterior of the blower to remove dirt and debris. For long-term storage, drain the fuel tank and run the engine until it stops to clear the carburetor of fuel. Store the blower in a dry, clean area away from direct sunlight and extreme temperatures.
