- Engine Maintenance: We recommend checking and cleaning the air filter regularly. A dirty filter reduces engine efficiency. Check the spark plug every 25 hours of work. Clean the carburetor periodically to avoid dirt buildup that could compromise engine operation.
- Fuel System: Check the fuel tank and fuel filter. Clean the tank and replace the filter if necessary. Always use a fresh mixture of petrol and oil (for 2-stroke engines) in the proportions recommended by the manufacturer.
- Transmission and Cutting Head: Lubricate the transmission shaft according to the manufacturer's instructions. Use the specific grease recommended for your model. Check the cutting head and replace the nylon line or blades when worn. Ensure the head is mounted correctly and that there are no abnormal vibrations during use.
- Storage: Store the brushcutter in a dry place protected from the weather. Avoid direct exposure to sunlight or humid conditions. Drain the fuel from the tank if the tool will not be used for a long period. Start the engine until the fuel in the carburetor is completely exhausted to prevent deposits.
8. What Percentage of Mixture is Needed for a Petrol Brushcutter?
The percentage of mixture needed for a petrol brushcutter depends on the type of engine. Two-stroke (2T) engines require a mixture of petrol and specific two-stroke oil, while four-stroke (4T) engines use only petrol and oil separately. Here we focus on two-stroke engines, which are the most common in brushcutters.
Recommended Mixture Percentage:
- 2% (50:1). Many modern two-stroke engines require a 2% mixture, i.e., 50 parts of petrol for 1 part of oil. This is the most common mixture recommended by major manufacturers.
- 2.5% (40:1). Some engines require a slightly richer 2.5% mixture, which corresponds to 40 parts of petrol for 1 part of oil. This percentage is often used in older engines or with specific requirements.
- 3% (33:1). In particular cases or for very old engines, a 3% mixture may be necessary, i.e., 33 parts of petrol for 1 part of oil. This is less common but still used in some models.
Below are some useful tips on preparing the mixture and its storage:
- Use Unleaded Petrol: Prefer fresh, high-quality petrol with an adequate octane number (often 95 or higher).
- Prepare Only the Necessary Amount: The petrol and oil mixture has a limited shelf life, generally no more than 30 days. Prepare only the amount you expect to use during this period to avoid mixture degradation.
- Store Properly: Store the mixture in an airtight, fuel-resistant container in a cool place away from direct sunlight.
9. What Happens if Petrol is Used Instead of the Mixture?
Using pure petrol in a two-stroke petrol brushcutter that requires a mixture of petrol and oil can cause serious engine damage. Here is what happens and why it is essential to always use the correct mixture:
- Lack of Lubrication: Two-stroke engines do not have a separate lubrication system like four-stroke engines. The oil in the mixture is essential for lubricating the engine's moving parts, such as pistons, cylinders, and bearings. Without oil, the engine's moving parts operate dry, causing a rapid increase in friction and heat. This leads to accelerated wear and damage to metal surfaces.
- Engine Overheating: The oil in the mixture also helps dissipate the heat produced by the engine. Without oil, the engine cannot effectively dissipate heat, leading to overheating. Overheating can cause piston deformation, gasket melting, and engine seizure, where parts lock up and stop functioning properly.
- Component Wear: The lack of lubrication leads to rapid deterioration of engine components, such as piston rings and bearings. This can cause irreparable damage that requires engine replacement or costly repairs. When the engine's moving parts overheat and expand, they can seize, rendering the engine unusable.
- Ignition Problems: Using pure petrol can lead to abnormal carbon deposits on spark plugs and in the carburetor, compromising ignition and engine operation.
10. What Does It Mean When a Brushcutter Emits White Smoke?
White smoke emitted by a brushcutter can indicate various problems, often related to fuel combustion and engine lubrication. Here are the most common causes and how to address them:
- Incorrect Fuel Mixture. If the petrol and oil mixture contains too much oil, the engine will burn more oil than necessary, producing dense white smoke. It is important to follow the manufacturer's recommended proportions. We also remind you that using non-specific oil for two-stroke engines or low-quality oil can cause incomplete combustion and produce white smoke.
- Carburetion Problems. An incorrectly adjusted carburetor can cause an overly rich air-fuel mixture, increasing oil combustion and producing white smoke. A dirty or clogged carburetor can compromise the correct fuel dosage, leading to inefficient combustion and the formation of white smoke.
- Environmental Conditions.. At low temperatures, the engine may not quickly reach optimal operating temperature, causing incomplete combustion and the production of white smoke. In high humidity conditions, water present in the fuel can evaporate during combustion, contributing to the formation of white smoke.
- Engine Wear and Problems. Worn or damaged gaskets can allow oil to enter the combustion chamber, causing white smoke. A worn cylinder or piston can compromise engine sealing, allowing oil to burn along with the fuel.
11. What is the Difference Between a 2-Stroke and a 4-Stroke Brushcutter?
2-stroke and 4-stroke brushcutters are mainly distinguished by engine operation, which affects various aspects such as power, maintenance, fuel efficiency, and usability. Here is a detailed overview of the main differences between these two types of engines:
1. Engine Cycle
- 2-Stroke Brushcutter: The 2-stroke engine completes a combustion cycle in two phases: the piston's upward stroke (compression and ignition) and the downward stroke (expansion and expulsion). It uses a mixture of petrol and oil to lubricate the engine, meaning the oil is burned along with the fuel.
- 4-Stroke Brushcutter: The 4-stroke engine completes a combustion cycle in four distinct phases: intake, compression, combustion, and exhaust. It uses pure petrol and has a separate lubrication system for the oil, which is not burned along with the fuel.
2. Power and Performance
- 2-Stroke Brushcutter: Generally more powerful at the same displacement due to combustion every two piston cycles. Tends to be lighter and more compact, facilitating transport and prolonged use.
- 4-Stroke Brushcutter: Slightly less powerful than 2-strokes at the same displacement, as combustion occurs every four piston cycles. Greater fuel efficiency and fewer emissions due to more complete combustion and a separate lubrication system.
3. Maintenance and Durability
- 2-Stroke Brushcutter: Requires a precise mixture of petrol and oil and frequent cleaning of the spark plug and carburetor due to oil combustion. May have a shorter lifespan compared to 4-strokes if not properly maintained due to faster wear of moving parts.
- 4-Stroke Brushcutter: Requires regular oil changes but does not require mixing petrol and oil. Maintenance is more similar to that of a car. Generally more durable due to separate lubrication and more efficient combustion.
4. Usability
- 2-Stroke Brushcutter: Simpler and quicker to start due to the simpler engine design. Ideal for heavy work and for those who need a lightweight and manageable machine.
- 4-Stroke Brushcutter: Heavier and more complex, requiring more attention in maintenance. Suitable for those seeking fuel efficiency and lower emissions, preferred for longer and continuous work.
12. What is the Ideal Power for a Garden Brushcutter? How Many Horsepower (HP) Should a Good Brushcutter Have?
