- Secure Cap: Tightly close the fuel cap. Wipe away any spilled fuel.
4. Operating Instructions
4.1 Starting the Engine
- Prime the Carburetor: Press the primer bulb several times until fuel is visible.
- Set Choke: Move the choke lever to the 'CLOSED' or 'START' position.
- Set Throttle: Place the throttle lever in the 'START' or 'HALF THROTTLE' position.
- Pull Starter Rope: Hold the brush cutter firmly. Pull the starter rope slowly until resistance is felt, then pull sharply and quickly. Repeat until the engine fires (usually 1-3 pulls).
- Open Choke: Once the engine fires, move the choke lever to the 'OPEN' or 'RUN' position.
- Restart (if necessary): If the engine stalls, repeat steps 4 and 5. If it runs, let it warm up for a few seconds before engaging the throttle fully.
4.2 Stopping the Engine
- Release Throttle: Allow the engine to idle for a few seconds.
- Press Stop Switch: Press and hold the engine stop switch until the engine completely shuts off.
4.3 Cutting Techniques
Always wear the backpack harness for balanced weight distribution and reduced fatigue.
- Line Trimmer Operation (430 mm cutting width): Use a sweeping motion from side to side. For automatic line feed, tap the cutting head gently on the ground while the engine is running at full throttle.
- Blade Operation (255 mm cutting width): For dense brush and small saplings, use the 3-tooth blade. Cut with a controlled, steady motion. Be aware of potential kickback.
- Maintain Control: Always keep a firm grip on the handlebar and maintain good balance.
