5. Operation
Proper operation ensures efficiency and safety. Always wear protective gear as outlined in Section 2.
5.1 Fueling the Brush Cutter
The FX-MS152 uses a 2-stroke engine and requires a specific fuel mixture.
- Fuel Mix: Prepare a mixture of unleaded gasoline and 2-stroke engine oil at a ratio of 1:40 (e.g., 25ml oil per 1 liter of gasoline). Use high-quality 2-stroke oil.
- Refueling: Ensure the engine is off and cool. Open the fuel tank cap slowly to release any pressure. Pour the prepared fuel mixture into the tank using a funnel to prevent spills. Securely close the fuel cap.
5.2 Starting the Engine
- Place the brush cutter on a flat, stable surface.
- Set the ignition switch to the 'ON' position.
- Engage the choke (usually by pushing a lever or button).
- Press the primer bulb several times until fuel is visible in the return line.
- Pull the starter cord firmly and steadily until the engine fires (it may run briefly and then stop).
- Once the engine fires, disengage the choke (move it to the 'OFF' or 'RUN' position).
- Pull the starter cord again until the engine starts and runs smoothly.
- Allow the engine to warm up for a few moments before engaging the throttle.
5.3 Operating Techniques
Adjust the shoulder harness for optimal balance and comfort. Hold the brush cutter with both hands on the ergonomic handlebar. Maintain a firm grip and keep the cutting head away from your body.
- Using the Line Head: For grass and light weeds, swing the cutting head in a sweeping motion from side to side. The automatic unwinding feature allows for easy line extension by tapping the head on the ground while running.
- Using the Blade: For thicker brush and small saplings, use the 3-tooth blade. Approach the material slowly and cut in a controlled manner. Avoid hitting hard objects like rocks or metal.
- Speed Control: Utilize the stepless speed regulator for personalized adjustment of cutting speed based on the task.

6. Maintenance
Regular maintenance is crucial for the longevity and optimal performance of your FUXTEC FX-MS152 brush cutter.
- Cleaning: After each use, clean the cutting head, protective shield, and engine housing to remove grass, dirt, and debris. Ensure cooling fins are clear.
- Air Filter: Regularly inspect and clean the air filter. A clogged air filter can reduce engine performance and increase fuel consumption. Replace if damaged.
- Spark Plug: Check the spark plug periodically. Clean or replace it if it is fouled or worn.
- Cutting Attachments: Inspect the blade for sharpness and damage. Sharpen or replace as needed. Check the line head for wear and replace the trimmer line when necessary.
- Drive Shaft: Periodically check the drive shaft for any signs of wear or damage. Lubricate as recommended in the full manual.
- Fuel System: To protect fuel lines and prevent issues, it is recommended to empty the fuel tank after each use, especially if storing the unit for an extended period. Do not use old fuel (more than a few weeks old) as it can degrade and cause engine problems.
- General Inspection: Regularly check all nuts, bolts, and screws for tightness. Tighten any loose fasteners.
