The brand of gasoline suitable for the specific model of tool is usually indicated in the instruction manual. If you neglect the manufacturer’s recommendations and fill the tank with the wrong octane rating, over time the device may simply fail. Trimmers come with two-stroke and four-stroke engines. Their refueling and service are significantly different.

Two-stroke petrol trimmers

Motor trimmers equipped with a two-stroke engine do not have a separate oil supply system for lubricating rubbing parts. Therefore, they need to be filled not with pure gasoline, but with a mixture of it with engine oil. Remember that the oil must be special, designed for two-stroke engines. Using automotive engine oil can damage the tool.

Trimmers with a two-stroke engine should be fueled with AI-92 brand gasoline. Of course, he will be able to work on gasoline with a higher octane rating. But when refueling with AI-95 gasoline, the engine will overheat and run unevenly.

Mix oil and gasoline in the right proportion. If there is too little grease, scuffing will appear on the piston surface and cylinder walls, then the piston ring will collapse and the engine will jam. An excess of oil is not so critical, but it will also lead to unpleasant consequences. Carbon deposits will form on the piston and the piston ring will coke, resulting in a drop in power.

Typically, the proportions of gasoline and oil are indicated in the instructions for the tool. Many manufacturers prescribe a 50: 1 ratio. one part of the oil is poured into 50 parts of the fuel. Therefore, per liter of fuel should be 20 ml of oil. If the engine is worn out, or the tool is operating at high load, the amount of lubricant can be increased to 25: 1 by pouring 40 ml per liter of gasoline.

Four-stroke petrol trimmers

Trimmers driven by a four-stroke engine have a more complex device. Gasoline and oil are poured into different containers, from where they are then fed into the engine. In such models, grease intended for two-stroke engines cannot be used.
Gasoline for a trimmer with such a motor should be AI-92 or AI-95. It is not recommended to use fuel with a lower octane rating. this will lead to unstable engine operation.

Many trimmer manufacturers are strongly advised to use fuels and lubricants manufactured under their own logo. Often they are more expensive than peers sold under other names. Is it worth it to overpay for branded oil?
Companies that produce gasoline tools do not produce fuels and lubricants. They buy these products from companies involved in the production of oils, and then pack the grease in containers with their own symbols. Therefore, you can safely buy the right oil from any manufacturer. The main thing is that it corresponds to the engine parameters.

For those people who have a summer house or a country house, very often difficulties arise with overgrown grass on the site. As a rule, several times a season it is necessary to mow it and get rid of thickets. Currently, the market offers a wide selection of equipment for the garden. One of these assistants can be attributed to the lawn mowing, in other words. a trimmer. For effective and long-term operation of such equipment, it is necessary to refuel it with high-quality fuel or correctly prepared fuel mixtures.

What gasoline can be poured into the trimmer?

Before determining which gasoline can be poured into the trimmer, It is necessary to define some of the concepts used.

  • Trimmers can be with four-stroke or two-stroke engines. Four-stroke trimmers are the most powerful and complex in design, the lubrication of parts of its engine is carried out by an oil pump. The engine runs on clean gasoline. For push-pull units. simpler ones. it is necessary to prepare a fuel mixture consisting of gasoline and oil. That’s due to the amount of oil that is in the fuel, and friction parts are lubricated in the cylinder of this engine.
  • To prepare the mixture you need gasoline of a certain brand AI-95 or AI-92. The brand of gasoline depends on its ignition rate. the octane rating. The lower this indicator, the faster gasoline burns and its greater consumption.

Many lawn mowers have two-stroke engines that operate primarily on AI-92 gasoline. Fuel for them must be mixed independently. It is better to pour gasoline of the brand that is specified for it by the manufacturer into the lawn mower, otherwise the trimmer will fail faster. For example, with AI-95 gasoline, the engine will quickly overheat, and when choosing AI-80, the fuel mixture is of very low quality, so the engine will be unstable and with low power.

In addition to choosing a brand of gasoline, when preparing the fuel mixture for lawn mowers, you need to use a special oil designed specifically for two-stroke engines. Semi-synthetic and synthetic oils are well suited for lawn mowing. Semi-synthetic oils are in the average price range, suitable for such equipment from any manufacturer, well lubricate the necessary elements of the motor. Synthetic oils are more expensive, but when they are used, the engine will last longer. In any case, when buying equipment, you should carefully read the instructions, as sometimes the manufacturer gives recommendations on the use of specific brands of oil.

If you purchase Russian-made oil, then it must be labeled. 2T. For the long service life of your equipment and its good condition, you never need to use oils of unknown production.

The proportion of the fuel mixture

If the mixture is diluted correctly, for example, following the instructions below, then the equipment will last you more than one year without serious technical breakdowns. At the same time, fuel consumption will be low, and the result of work will be high. The fuel preparation process should always be the same and constant. It is best to use the same ingredients always, without changing the brand specified by the manufacturer.

Do not add a lot of oil, this can damage the engine, but you should not save on it either. To maintain the correct proportions, always use the same measuring container so as not to be mistaken with the quantity. You can use medical syringes to measure the oil, but some manufacturers, along with the oil, provide complete and measured containers with risks.

The most correct ratio of oil to gasoline is considered to be 1 to 50, where 50 is the amount of gasoline, and the amount of oil is 1. For a better understanding, we explain that 1 liter is equal to 1000 ml. So, to get a ratio of 1 to 50, 1000 ml is divided by 50, it turns out 20 ml. As a result, you need to add only 20 milliliters of oil to 1 liter of gasoline. To dilute 5 liters of gasoline, you will need 100 ml of oil.

In addition to observing the correct proportion, it is necessary to observe the technology of mixing the ingredients. In no case can you just add oil to the gas tank. It is better to follow the following step-by-step instructions.

  • To dilute the mixture, you must prepare in advance a container in which you will mix gasoline and oil. This can be a clean metal or plastic canister with volumes of 3, 5 or 10 liters, to make it easier to calculate the amount of oil. Do not use bottles from under drinking water for this purpose. they are made of thin plastic, which can dissolve from gasoline. Use a special measuring container to measure the oil. But if there is none, then, as already noted, high-dose medical syringes are suitable.
  • Pour gasoline into the canister without adding a couple of centimeters to the full volume. In order not to spill gasoline, take a watering can or insert a funnel into the neck of the canister. Then, in the syringe or in the measuring device, draw the right amount of oil and pour into a container with gasoline. It is not recommended to do the opposite. pour gasoline into the oil.
  • Close the lid tightly with a bottle and stir the resulting mixture. If during the preparation of the mixture or its mixing a part of the fuel spills out, it is necessary to immediately wipe the canister with a dry rag.
  • Be sure to observe fire safety measures. Dilute the mixture away from fire and in no case do not leave leftovers of fuel and used materials out of the reach of children.

And one more important point: it is better to cook the mixture exactly the amount that fits in the fuel tank of your lawn mowers. It is undesirable to leave the remains of the mixture.

Features refueling lawn mowers

When the mixture is cooked and ready for use, it must be carefully poured into the fuel tank. Since gasoline is a toxic liquid, safety precautions must be observed when working with it. Work must be carried out in calm weather and away from strangers. And also for pouring fuel into the tank you need to use a watering can or funnel, with which you previously diluted the mixture. Otherwise, the mixture may spill, go unnoticed, and ignite when the engine is heated.

The fuel bank itself must be cleaned of external contaminants and only then unscrew its cover in order to refuel with the prepared fuel. After the fuel has been filled, the tank should not be left open, as insects or earth can get into it, as a result of which the fuel filter will clog. Pour fuel into the tank to the specified mark or less, and then topping up during operation.

As noted above, you should not prepare the mixture more than necessary for work, it is better to cook less and, if necessary, repeat the process, mixing gasoline with oil again. If you still have unused fuel, then you must use it for 2 weeks.

During storage, the container must be tightly closed with a lid. Fuel must be stored in a cool room, in a place where the sun does not penetrate. It is worth remembering that with prolonged storage of the mixture, the oil liquefies and loses its properties.

Whatever brand your equipment is, it requires respect and quality fuel. If you follow all the recommendations and use fuel economically, your lawn mower will serve you for more than one season, and the land will always be in perfect order, without weeds and dense thickets of grass.

Now there are not enough people who use the ordinary scythe in their own personal plot. This "grandfather" the method does not actually occur. Well, many already have no idea how to handle it, sharpen and rivet. With the development of technology, devices appeared under the name of trimmers.

Now there are not many people who use the ordinary braid on their own infield. This "grandfather" the method is almost never found. Yes, and many already have no idea how to handle it, sharpen and rivet. With the development of technology, devices called trimmers have appeared.

What are the trimmers?

There are two main types of such devices. It is gasoline and electric. From the name it is clear that their main difference is the power source. Each type has both advantages and disadvantages. The advantage of gasoline is the lack of a power cord, which does not limit the owner in moving around the site during operation. The electric one needs a 220 V network for power. There is no way to do without an extension cord, which will constantly interfere and get underfoot.

Modern trimmer, which runs on fuel, thanks to the presence of various interchangeable heads from an ordinary scythe has turned into a means of small mechanization with many functions. By installing the appropriate nozzle, it is not difficult for the owner to form a crown in the bushes on a personal infield. In the snowy winter it can be used as a snow blower. Replacing the working heads of the trimmer does not take much time and can be done both with the use of the tool, and without it.
