Operating Instructions

Starting the Engine:

1. Place the brush cutter on a flat, stable surface.
2. Press the manual fuel pump (primer bulb) several times until fuel is visible in the bulb.
3. Set the choke lever to the "START" or "CHOKE" position (cold start).
4. Pull the starter cord firmly and smoothly until the engine fires. Do not pull the cord to its full extension.
5. Once the engine fires (usually after 1-3 pulls), move the choke lever to the "RUN" position.
6. Allow the engine to warm up for a few moments before engaging the throttle.

Operating the Brush Cutter:

• Always hold the brush cutter firmly with both hands.
• Maintain a balanced stance and good footing.
• Swing the cutting head in a smooth, sweeping motion, cutting from right to left for optimal efficiency.
• Avoid hitting hard objects like rocks or fences, as this can damage the cutting line or head.
• To extend the cutting line, tap the Tap&Go head gently on the ground while the engine is running at full throttle.
• Take frequent breaks to avoid fatigue.
