3. Setup and Assembly
3.1 Unpacking and Initial Inspection
Carefully remove all components from the packaging. Inspect for any damage that may have occurred during shipping. If any parts are missing or damaged, contact your dealer immediately.
3.2 Handlebar Assembly
- Attach the handlebar to the shaft using the provided clamp and bolts.
- Ensure the handlebar is centered and securely tightened to prevent rotation during operation.
3.3 Guard and Cutting Head Installation
- Mount the safety guard to the shaft above the cutting head, ensuring it is firmly secured.
- Install the 3-tooth steel blade onto the cutting head, following the rotation direction indicated on the blade. Use the provided tools to tighten the retaining nut securely.
- Alternatively, if using a trimmer line head, ensure the line is properly spooled and secured.
3.4 Fueling the Engine
The Hecht 142 BTS uses a 2-stroke engine and requires a specific fuel mixture of unleaded gasoline and 2-stroke engine oil. Refer to the engine unit for the exact mixing ratio (typically 25:1 or 40:1, consult engine label).
- Always mix fuel in a separate, approved fuel container.
- Pour the correct amount of 2-stroke oil into the gasoline and shake well to ensure thorough mixing.
- Carefully pour the mixed fuel into the brush cutter's fuel tank. Do not overfill.
- Securely close the fuel cap.
Caution: Gasoline is highly flammable. Handle with extreme care. Do not refuel while the engine is hot or running. Refuel in a well-ventilated area away from open flames or sparks.
4. Operating Instructions
4.1 Starting the Engine
- Place the brush cutter on a flat, stable surface.
- Set the engine stop switch to the "ON" position.
- Engage the choke lever (if the engine is cold).
- Press the primer bulb several times until fuel is visible in the return line.
- Pull the starter cord firmly and steadily until the engine starts. Do not pull the cord to its full extension.
- Once the engine starts, gradually disengage the choke. Allow the engine to warm up for a few moments before operating at full throttle.
4.2 Operating the Brush Cutter
Attach the backpack harness and adjust it for comfortable weight distribution. Hold the brush cutter firmly with both hands on the handlebar. Maintain a balanced stance. Apply throttle gradually to increase cutting speed. Use a sweeping motion to cut vegetation. Avoid striking hard objects like rocks or metal.
4.3 Stopping the Engine
To stop the engine, release the throttle trigger and move the engine stop switch to the "OFF" position. Allow the engine to cool down before storing.
5. Maintenance
Regular maintenance ensures the longevity and optimal performance of your brush cutter.
5.1 Cleaning
After each use, clean the exterior of the machine, especially the cutting head and guard, to remove grass, dirt, and debris. Do not use high-pressure water directly on the engine or electrical components.
5.2 Air Filter Maintenance
Check the air filter regularly (e.g., every 10 operating hours). A dirty air filter can reduce engine performance. Clean or replace the air filter as needed. Refer to the engine manual for specific instructions on accessing and cleaning the air filter.
5.3 Spark Plug Inspection
Inspect the spark plug periodically (e.g., every 25 operating hours). Clean or replace if it is fouled or worn. Ensure the correct spark plug gap is maintained.
5.4 Cutting Blade Care
Regularly inspect the 3-tooth steel blade for sharpness and damage. A dull or damaged blade can reduce cutting efficiency and increase vibration. Sharpen or replace the blade as necessary. Always wear heavy-duty gloves when handling the blade.
5.5 Storage
For long-term storage, drain the fuel tank or run the engine until it runs out of fuel to prevent fuel degradation. Clean the machine thoroughly. Store in a dry, well-ventilated area, out of reach of children.
