4. Setup and Assembly
Follow these steps to assemble your brush cutter before first use.
4.1 Attaching the Handlebar
- Loosen the handlebar clamp bolts on the main shaft.
- Position the handlebar onto the shaft at a comfortable working height and angle.
- Ensure all control cables are routed correctly and not pinched.
- Tighten the clamp bolts securely.
4.2 Installing the Cutting Guard
- Slide the cutting guard onto the lower shaft, ensuring it is oriented correctly to protect against debris.
- Secure the guard with the provided screws or bolts. Do not operate the brush cutter without the guard properly installed.
4.3 Mounting the Cutting Head
Your HECHT 135 BTS comes with two interchangeable cutting heads: a 3-tooth metal blade and a dual-line spool head.
- Ensure the engine is off and the spark plug cap is removed.
- Insert the locking pin into the gearbox hole to prevent the shaft from rotating.
- For Metal Blade: Place the blade onto the shaft, ensuring it sits correctly on the support flange. Secure it with the washer and nut, tightening firmly (often left-hand thread).
- For Spool Head: Thread the spool head onto the shaft, turning clockwise until it is securely fastened.
- Remove the locking pin.
4.4 Attaching the Shoulder Strap
- Attach the shoulder strap to the designated hook or loop on the main shaft.
- Adjust the strap length so the cutting head is balanced and comfortable for your working posture, allowing for a slight bend in your arms.
4.5 Fueling the Brush Cutter
The HECHT 135 BTS uses a 2-stroke engine, requiring a specific petrol-oil mixture. Refer to the engine manufacturer's recommendations for the correct mixing ratio (typically 25:1 or 50:1, depending on the oil type).
- Use fresh, unleaded petrol and high-quality 2-stroke engine oil.
- Mix the fuel in a separate, approved fuel container.
- Ensure the engine is off and cool before refueling.
- Carefully pour the mixed fuel into the fuel tank (capacity 0.7 L), avoiding spills.
- Securely close the fuel cap.
5. Operating Instructions
5.1 Starting the Engine
- Place the brush cutter on a flat, stable surface.
- Set the ON/OFF switch to the 'ON' position.
- Engage the choke (if the engine is cold).
- Press the primer bulb several times until fuel is visible.
- Hold the brush cutter firmly with one hand on the handlebar and the other on the starter grip.
- Pull the starter cord slowly until resistance is felt, then pull sharply and quickly until the engine fires (usually 1-3 pulls).
- Once the engine fires, disengage the choke (if applicable).
- Allow the engine to warm up for a few moments before applying full throttle.
5.2 Using the Brush Cutter
Hold the brush cutter firmly with both hands on the handlebar. Maintain a wide stance for balance. The shoulder strap should support the weight of the machine, allowing you to guide it with minimal effort.
- Cutting Technique: Use a sweeping motion from side to side. For dense growth, cut in smaller sections.
- Blade Use: Ideal for thick weeds, brush, and small saplings. Be aware of kickback when using the blade.
- Spool Head Use: Best for grass, light weeds, and trimming around obstacles. Advance the line as needed by tapping the head on the ground (tap-and-go system) or manually.
- Maintain RPM: Operate at a consistent, high RPM for efficient cutting and to prevent engine strain.
- Avoid Obstacles: Do not strike hard objects like rocks, fences, or concrete with the cutting head.
5.3 Stopping the Engine
- Release the throttle to allow the engine to idle.
- Move the ON/OFF switch to the 'OFF' position.
- Wait for all moving parts to come to a complete stop before setting the machine down.
6. Maintenance
Regular maintenance ensures the longevity and safe operation of your HECHT 135 BTS brush cutter.
6.1 After Each Use
- Clean the Unit: Remove grass, dirt, and debris from the engine, cutting head, and guard. Use a brush or compressed air.
- Inspect Cutting Head: Check the blade for sharpness and damage, or the line spool for wear and proper function. Replace or sharpen as needed.
- Check Fasteners: Ensure all nuts, bolts, and screws are tight.
6.2 Periodical Maintenance
- Air Filter: Clean the air filter regularly (every 5-10 hours of operation, more often in dusty conditions). Wash foam filters in warm, soapy water, rinse, dry, and lightly oil. Replace paper filters if heavily soiled.
- Spark Plug: Inspect the spark plug every 20-30 hours. Clean carbon deposits and adjust the gap if necessary. Replace if electrodes are worn or damaged.
- Fuel Filter: Inspect and replace the fuel filter in the tank annually or if fuel flow issues occur.
- Gearbox Lubrication: Check and replenish the grease in the gearbox (at the cutting head end) as per manufacturer recommendations, typically every 25-50 hours.
- Cooling Fins: Keep the engine's cooling fins clean to prevent overheating.
6.3 Storage
- For long-term storage, drain the fuel tank and run the engine until it stops to clear the carburetor of fuel.
- Clean the entire unit thoroughly.
- Store in a dry, well-ventilated area, away from direct sunlight and heat sources.
