4. Operating Instructions

Starting the Engine:

1. Place the strimmer on a flat, stable surface.
2. Ensure the fuel tank is filled with the correct fuel mixture.
3. Set the choke lever to the 'START' position (usually closed).
4. Press the primer bulb several times until fuel is visible in the return line.
5. Pull the starter cord firmly and smoothly 4-6 times until the engine briefly fires.
6. Once the engine fires, move the choke lever to the 'RUN' position (usually open).
7. Pull the starter cord again until the engine starts and runs smoothly.
8. Allow the engine to warm up for a few moments before engaging the throttle.

Operating the Strimmer:

• Wear the adjustable shoulder strap for comfortable and balanced operation.
• Hold the handle firmly with both hands.
• Engage the throttle to increase engine speed. The throttle adjustment switch allows for speeds between 6500-7000rpm/min for optimal cutting.
• Move the cutting head steadily across the vegetation. For grass trimming, use a sweeping motion. For brush cutting, approach thicker vegetation carefully.
• Avoid hitting hard objects like rocks, fences, or concrete to prevent damage to the cutting head or blade.
• To stop the engine, release the throttle and press the engine stop switch.

• **Spark Plug:** Inspect and clean the spark plug. Replace if it's fouled or worn.
• **Fuel Filter:** Check and clean or replace the fuel filter in the fuel tank.
• **Carburetor:** The diaphragm-type carburetor is designed for smoother operation. If issues arise, professional servicing may be required.

8. User Tips

• **Comfortable Operation:** Utilize the adjustable and thick shoulder straps to distribute the machine's weight (approx. 7.0kg) evenly, reducing fatigue during extended use.
• **Versatile Use:** Remember to switch between the 3T metal blade for tougher brush and the high-strength rope for general grass trimming, optimizing performance for different terrains.
• **Fuel Freshness:** Always use fresh fuel mixture. Stale fuel can cause starting difficulties and engine performance issues.
