Choosing a petrol cutter for yourself functions, features, characteristics
To spend less time and effort mowing grass in the area, you need to use the mechanisms designed for this, petrol cutters, trimmers and lawn mowers. With their help, it will be possible to maintain the area adjacent to the house in excellent condition. The advantage of a brushcutter is that it is not tied to a power source like electric scythes. In addition, its application allows mowing grass on uneven terrain, as well as in hard-to-reach places (for example, under a bush). It is also less safe, since when using electricity there is always a possibility of electric shock.
What to look for when choosing a petrol cutter?
Since the purpose of the scythe is precisely to mow vegetation, the first thing to do is to look at the cutting tool. Domestic petrol cutters are equipped with steel or plastic knives. A saw blade or nylon scaffolding is also used as a cutting part. Based on this, it must be taken into account that the fishing line is absolutely unsuitable for work in areas where there are thickets of bushes. She also will not be able to cut small branches and young shoots from trees. Plastic knives, in turn, cannot be sharpened.
It is better to purchase more versatile models that have the ability to change the cutting tool. In this case, you need to ask how easily and quickly such a replacement is made. You need to understand that steel knives and discs become dull during operation. What then? If they are sharpened, how? Can you do it yourself? If the manufacturer provides spare cutting tools, how much is included in the package and can be purchased at retail? After all, the petrol brush itself is designed for a long service life. A steel knife may break, but where to get another?
Chainsaws are usually equipped with a 2 or 4 stroke engine. The first ones are somewhat lighter, but their operation is much more noisy. Although the set may include headphones that are used during work. Therefore, everyone chooses a model at their discretion. The scythe power can be up to 1.5 hp. Another such nuance of the 4T model needs to be kept somewhat tilted, at an angle. This is necessary for oil to get on all parts of the braid. But the 2T models can be held as you like, in any position they work stably.
Practice shows that corner models are less reliable, and their power is less. However, with a bent bar, steel knives are not used, since with such a configuration, the knife is easy to break. There are models with a folding bar, but they are short-lived.
The handles can be of various shapes. They are called T, D or J shaped. The T-handle is well suited for work in open and relatively level areas. This configuration follows the shape of a traditional braid and allows for large, wide sweeps. The D-shaped handle is more suitable for working in difficult areas: along fences and buildings, under bushes, among trees. For areas with high vegetation, a scythe with a J-handle works well. By the way, it is the best in terms of safety.
And yet, focusing on the technical characteristics and cost of a particular model, do not forget about the convenience of using this particular braid. If it fits well in your hands, does not impede movement, then, most likely, your choice was made correctly. I recommend to see the specialist tells about the choice of brushcutters and its maintenance:
Oil selection and fuel mixture for petrol cutters
So, have you finally become the owner of a petrol brushcutter or lawn mower? And your imagination is already creating images of how you courageously cope with the dense grass. However, the dream of a perfect lawn remains a dream, when the question involuntarily arises: what oil to use and what are the proportions of mixing it with gasoline?
You can find a lot of information on the correct preparation of the fuel mixture on the Internet. This topic is actively discussed on forums and other thematic resources. But, despite such an active discussion, there are many inconsistencies that have to be dealt with.
In fact, it doesn’t matter what technique is used, it can be a lawn mower, a brushcutter or a chain saw, they are united by one two-stroke gasoline engine. Unlike the 4T, it does not have an oil sump. It requires the preparation of a special fuel mixture, consisting of gasoline and oil. The resulting liquid is fed directly to the engine (carburetor). In the process of use, all actively working parts are thoroughly lubricated, contributing to trouble-free operation under all operating conditions.
Lawn Mower Engine Oil
Depending on the chemical composition, lubricants are divided into the following main groups:
Mineral. They are made on the basis of oils obtained from petroleum distillates. They are characterized by high viscosity and require frequent replacement. The material is intended for low power appliances with an air cooling system. Recommended for use in warm weather.
Semi-synthetic. They represent a kind of golden mean. They are based on a mixture of mineral and synthetic oils. A similar lubricant can be used in 2T and 4T engines, gardening and other equipment with air and liquid cooling.
Synthetic. They are made on the basis of special synthetic components containing esters. They are characterized by low viscosity and long service life. Can be used all year round, regardless of temperature conditions. Ideal for demanding, demanding applications with constant variable performance.
Any two-stroke oil, due to its 20% solvent composition, mixes well with fuel and has the feature of complete combustion. Their second characteristic feature is the color, which can be green, red or blue. Of course, this does not mean that some lubricant is better, but some worse. This is done solely so that it is convenient for the user to distinguish oil from pure gasoline.
Classification of engine oils:
The required parameters of oils for 2T engines are prescribed in the requirements of API TC JASO FC, API TC JASO FC ISO GD and API TC JASO FC E-GC. The most widely used classification systems are API. Based on this, 2T engine oils are divided into 4 large groups:
TA. Suitable for household appliances with an air cooling system and an engine volume of no more than 50 cm3.
TB used for more powerful equipment with an air cooling system and a motor volume of 50.200 cm3.
TC. Used in technology with high demands for oil quality. It is a high-quality lubricant for two-stroke engines with a volume of 50.200 cm3. Great for lawn mowers, brushcutters, trimmers, chain saws and other garden equipment.
TD. For outboard boat motors with liquid cooling.
Most suitable material for 2T motors of API-TB and API-TC class. However, it is necessary to refer directly to the product passport, where the manufacturer indicates the brand of engine oil recommended for its equipment.
Important! For brushcutters, lawn mowers and other 2T garden equipment, a special engine oil is provided for two-stroke engines with an air cooling system and a marking for garden equipment. Do not use lubricant for 2T engines with liquid cooling system. Also not recommended for outboard engines, motorcycles and other equipment.
Oil to gasoline ratio for brushcutters: why is accuracy so important?
We all loved to cheat in childhood, so the process of preparing a fuel mixture is not only simple, but also interesting. First of all, it is worth considering the fact that the proportions of the mixture may be different. This depends on engine configuration, oil markings and manufacturer recommendations. The fact is that with an insufficient amount of lubricant, the cylinder and piston heat up, which leads to shallow scuffing of all rubbing surfaces and, consequently, to the failure of the cylinder. Piston group. Well, in the case of its excess, on the contrary, we get coking of the piston ring and the formation of a large amount of carbon deposits.
And even in spite of the fact that there is a generally accepted mixing ratio of 2% (for every liter of gasoline, 20 ml of lubricant). The proportions in the mixture are still recommended to be kept exactly.
How much oil to pour into gasoline for petrol cutters?
Everything is quite simple, with the right balance, the engine runs at full capacity, all parts are thoroughly lubricated and do not wear out. As a result, we get a confidently working technique that will last more than one season.
To know how much oil to add to the brushcutter, you need to familiarize yourself with the performance characteristics of the product. Proportional ratios can be presented in the following form: 1:25, 1:40 and 1:50, which means 1 part of oil for 25, 40 or 50 parts of gasoline.
1 liter of gasoline = 1000 ml
To determine the required amount of oil for a ratio of 1:25, you need 1000/25 and we will get a ratio of 40 ml.
We carry out the same actions for the ratio 1:40 and 1:50:
1:40 (for 1 liter of gasoline 25 ml of oil)
1:50 (for 1 liter of gasoline 20 ml of oil)
In order for the proportion of oil for petrol cutters to be observed correctly, it is recommended to use a special measuring container (not plastic). Eliminate the possibility of dirt and water getting into the fuel mixture. This may affect its quality. It is better to start preparing the mixture with gasoline. Pour it up to the required mark, then add oil. A couple of tilts of the container are sufficient for mixing. The liquid quickly combines and acquires a uniform hue, which, depending on the structure of the oil, can be red, green, blue or other. After that, the properly prepared mixture is poured into the equipment fuel tank.
Before using the equipment, make sure that the tank cap is tightly closed. If you have more fuel, then the remainder can be stored in a special canister or mixing container (no more than 14 days). It is recommended to drain the unused fuel.
Important! Be sure to follow the safety instructions. Mix fluids outdoors to prevent corrosive gasoline fumes from accumulating indoors. Wear gloves and long sleeves. Do not smoke or ignite anything.
Gasoline with an octane rating of AI-92 is considered the most popular fuel for two-stroke engines. Due to its relatively low cost, it is extremely rarely falsified. Therefore, not one hundred percent, but you can be sure of its quality. It is also permissible to use AI-95 fuel.
As for the storage of fuel, its period should not exceed 3 months. Over time, gasoline loses its properties, the resin content becomes higher and a polymerization process occurs, which adversely affects the combustion chamber. The fuel mixture for petrol cutters made of low-quality materials settles in the form of carbon deposits, as a result of which the main components and systems of the engine suffer.
Recommendations for use and storage
The fuel is ready, poured into the fuel tank, the first spurt and the long-awaited start. However, if you want the equipment to work as long as possible, it is recommended to run it in for the first time. To avoid overheating the engine, it is recommended to adhere to the average load. After the main elements of the system have been thoroughly lubricated, the load can be increased.
Certain rules should also be followed when preparing the braid for off-season storage:
Drain the remaining fuel from the fuel tank and carry out the final run until the fuel is completely depleted. Then, pause operation and make sure the engine is completely cool.
Unscrew the spark plug carefully and add about 5 ml of lubricant. Pull the starter handle slowly to distribute the oil evenly inside the engine. Then, return the candle to its original state. Store equipment in a cool dry place.
A little advice. Try not to let the line come into contact with hard objects when cutting. With this contact, the line will be cut. And since in this trimmer the line is not fed automatically, then every time you have to stop work, remove the reel and release the line again.
Spare coil storage space
It is very simple to install such a fishing line into the reel according to the internal scheme inside the reel. We insert the center of the line with a metal mount in the upper part of the reel, and draw the ends of the line along the grooves and bring it out.
It is stored at the top of the trimmer body.
In addition to the standard lawn line, my trimmer has a thick line for cutting rough weeds. It has the shape of a pigtail, i.E. Three lines are tightly intertwined. This line has its own spool.
We fill the line in the trimmer.
I want to devote today’s article to the sore subject of summer residents and gardeners of the entire post-Soviet space How to fill the line in the trimmer. Not many trimmer manufacturers answer this question in their instruction manuals. Therefore, it is difficult for ordinary gardeners to figure out how to do it correctly.
I want to start with a brief description of the technical characteristics of the trimmers.
So, trimmers are electric and gasoline. The cutting element for trimmers can be a line and a knife. The line is ordinary, four. Pentahedral and intertwined (in the form of a pigtail). Knives come in 2, 3 and 4 bladed knives. There are also plastic and metal knives.
The line feed system from the trimmer is manual, semi-automatic and automatic.
The development engineers who create new models of trimmers clearly calculate the diameter (thickness) of the line and the number of knife blades, according to the power of the trimmers. Otherwise, the motor is overloaded, resulting in damage. And these are additional and significant costs.
Trimmers on the market today:
With one nozzle only with a line.
With two line nozzles and three-four-blade knife.
With one nozzle only three-four-bladed knife.
Our Kulibins have long ago learned to improve any mechanisms. So, for example, some gardeners make successful, in their opinion, replacement of fishing line with a metal cable, or fishing line. But at the same time, they do not think about the safety of their own and their loved ones, because, like a cable with the power of a working trimmer, it can easily break out and not only injure the mower and others, but leave him crippled for life. Using a fishing line can and gives a better effect, I have never personally tried it than a trimmer line, but such work has a number of inconveniences: when it comes into contact with hard objects, it loosens or can simply be pulled out of the reel without limit.
So, what is called closer to the topic. Here is an example of how to thread the line into the trimmer (Trimmer BOSCH Art 30). Everything is very simple. We started.
After you have chosen the line for refueling, you need to cut off the required amount of line, because all the line in the skein will not be wound into the reel.
Cut off and start winding.
Remove the coil and the protective cover from the coil.
They took it off. We fasten one end of the line into the gap and carefully and evenly wind the line.
The amount of line should be such that the protective cover of the reel closes and the line on the reel unwinds a little by itself.
We put the other end of the line into the hole in the protective casing.
Next, we take the coil and the protective cover of the coil. We squirt the end of the line from the reel into the metal hole on the reel’s protective cover. We tighten the line a little.
We put it all on the trimmer. Turn the coil clockwise until it clicks.
They fixed it. Now we connect the trimmer to the network. We put the trimmer in the starting position for work. We turn on the trimmer. Excessive line length will be cut on the trimming blade.
Coil in trimmer
That’s all we start working on.
Heavy-duty line in a reel
This reel is attached to the trimmer in the same way as a reel with an ordinary line.
How to properly refuel your chainsaw to extend its life?
The engine of a modern chainsaw is a one- or two-cylinder carburetor engine. As a rule, two-stroke models are installed, although four-stroke models are occasionally found. The rotational speed of the working shaft reaches 13.5 thousand revolutions, which puts forward stringent requirements for the quality and composition of the fuel mixture.
Manufacturers inform users in sufficient detail how to refuel a chainsaw, but for many this issue remains not entirely clear. Let’s take a closer look at it.

What fuel should I use for my chainsaw?
Choosing the right fuel is an important and significant issue. The only correct approach to its solution is a careful study of the user manual, which indicates the type and brand of fuel, the proportions of mixing gasoline and oil, and also reflects all the features of this tool. Modern standards require the use of high-octane refined fuels and special types of engine oil.
Chainsaw device features
The chainsaw is a chain hand tool, the cutting body of which is driven by a carburetor engine.
Typically, this is a single cylinder two-stroke engine.
This design is simple, economical, and can work in any position.
The structure of the saw, in addition to the engine, includes:
- Cutting body (chain);
- Centrifugal clutch;
- Ignition, fuel supply system, air filters;
- Chain lubrication system;
The engine can be positioned vertically (heavy duty professional models) or horizontally (light household tools). Heavy duty saws are used for felling and crosscutting trunks and have a large frame size. Lightweight saws are used for cutting branches or sawing wood, and are usually purchased by private house owners, farmers, gardeners, etc.
The design of the tool is simple, which guarantees high strength and reliability. The engine shaft drives the drive sprocket through the clutch, which moves the chain along the tire using the drive sprocket. The two-stroke engine does not need a camshaft, valve system and other elements, which also contributes to increased structural reliability.
The centrifugal clutch is equipped with two clutches, which at low shaft speeds are pressed against each other, and with an increase in rotation speed, under the action of centrifugal force, they are pressed against the outer part of the clutch and drive the drive sprocket. The motor power determines the type of chain; the more powerful the saw, the greater the chain pitch (the distance between the teeth that determines the performance of the tool).
Refueling your chainsaw
For beginners, the question of how to refuel a chainsaw is especially relevant. However, the refueling process itself is not difficult at all. The main task is to formulate the fuel / oil mixture in the correct proportions. They are indicated in the instructions for the tool. Before refueling, you should carefully study the information given by the manufacturer in order to exclude the possibility of errors in the composition of the fuel mixture.
Storage conditions for the finished mixture
Most users usually prepare the fuel mixture for future use. This is due to the saving of time, it is believed that it is more correct to mix a large volume once, and then simply add fuel to the tool tank. This point of view is valid, but with important limitations. The finished mixture should not be stored for too long, as irreversible changes occur in it.
Ideally, it should only be cooked for one day, but this is considered too irrational by many. The permissible shelf life depends on the ratio and grade of the components. Most experts recommend not storing the mixture for more than 3 months. It is recommended to use metal cans and keep the mixture under a canopy, away from direct sunlight.
Gasoline to oil ratio
The standard ratio of oil to gasoline, which is relevant for most chainsaws, is 1 to 50. This means that 20 ml of oil must be added to 1 liter of gasoline. However, each manufacturer has its own requirements for the composition of the fuel mixture, which are due to the design of the engine, the peculiarities of its parameters and other factors. It is impossible to determine on your own what proportions are best suited for a given instrument.
Complete and accurate information can only be obtained from the user manual. If it does not contain any indication of the composition of the fuel mixture, then generally accepted practice should be followed and make it in a ratio of 1: 50. There are other options, from 1: 20 to 1: 50.
