How To Refuel The Trimmer

Gasoline for lawn mowers: which one to choose and how to dilute?

For those people who have a summer cottage or a country house, very often there are difficulties with the overgrown grass on the site. As a rule, it is necessary to mow it several times per season and get rid of thickets. A wide range of garden and vegetable garden equipment is currently on the market. One of these assistants can be attributed to the lawn mower, in other words. Trimmer. For effective and long-term operation of such equipment, it is necessary to fill it with high-quality fuel or properly prepared fuel mixtures.

What gasoline can I fill in the trimmer?

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

  • Trim tabs can be with four-stroke or two-stroke engines. Four-stroke trimmers The most powerful and complex in design, the lubrication of its engine parts is carried out by an oil pump. The engine runs on pure gasoline. For two-stroke units. simple ones. Requires preparation of a fuel mixture consisting of gasoline and oil. It is due to the amount of oil in the fuel that the rubbing parts in the cylinder of this engine are lubricated.
  • To prepare the mixture, you need gasoline of a certain grade AI-95 or AI-92. The brand of gasoline depends on its ignition speed. Octane number. The lower this indicator, the faster gasoline burns and the greater its consumption.
How To Refuel The Trimmer

Many models of lawn mowers have two-stroke engines running mainly on AI-92 gasoline. The fuel for them must be mixed independently. It is better to pour gasoline into the lawn mower of the brand that is defined for it by the manufacturer, 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 turns out to be of very low quality, therefore the engine will work unstable and with low power.

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

Fuel ratio

If the mixture is diluted correctly, for example, following the instructions below, then the technician will serve you for 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 must always be the same and constant. It is better to use the same ingredients always, and not change the brand indicated by the manufacturer.

It is NOT worth adding a lot of oil, it can damage the operation of the engine, but you should not save on it either. To maintain the correct proportions Always use the same volumetric container, so as not to be mistaken with the quantity. You can use medical syringes to measure the oil, but some manufacturers together with the oil Provide a set and a measuring container with risks.

The most correct ratio of oil to gasoline is 1 to 50, where 50 is the amount of gasoline and the amount of oil. 1. For a better understanding of the belt, that 1 liter is equal to 1000 ml. So, to get a ratio of 1 to 50, divide 1000 ml by 50, we get 20 ml. As a result, only 20 milliliters of oil need to be added to 1 liter of gasoline. To dilute 5 liters of gasoline, you need 100 ml of oil.

In addition to maintaining the correct proportion, you must also follow the mixing technology of the ingredients. In no case should you just add oil to the gas tank. 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 a volume of 3, 5 or 10 liters, to make it easier to calculate the amount of oil. DO NOT use drinking water bottles for this purpose. They are made of thin plastic, which can dissolve from gasoline. To measure oil Use a special measuring container. But if there is none, then, as already noted, medical syringes with a large dosage will do.
  • Pour gasoline into the canister, do not add 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 take the required amount of oil into a syringe or measuring device and pour it into a container with gasoline. It is not recommended to do the opposite. Pour gasoline into oil.
  • Close the bottle tightly and stir the mixture. If during the preparation of the mixture or its mixing, part of the fuel has spilled out, you must immediately wipe the canister with a dry cloth.
  • Be sure to follow fire safety measures. Dilute the mixture away from fire and under no circumstances leave leftover fuel or used materials within easy reach of children.

Features of refueling lawn mowers

When the mixture is prepared 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 to pour 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 heats up.

The fuel bank itself must be cleaned of external contaminants and only then Unscrew its cap in order to refuel with the prepared fuel. Once the fuel has been filled, the tank should not be left open, as insects or soil can enter the tank and clog the fuel filter. You need to fill the fuel in the tank to the indicated mark or less, and then refilled it during operation.

During storage, the container must be tightly closed with a lid. Store fuel in a cool room, out of the sun. It is worth remembering that during long-term storage of the mixture, the oil liquefies and loses its properties.

How to properly thread the line into the trimmer spool

There are different coils. For a reel working with one tendril, it is easier to thread the line than with others. There is a hole on the inside of the reel for fixing the line. You need to insert the tip of the fishing line into it and start winding.

Important. You need to wind in the opposite direction from the rotation of the coil to the trimmer. Look carefully, most likely in the same place, on the reel, the direction of winding will be indicated with an arrow. The winding can take about two to four meters of line. It depends on the size of the coil itself. At the end of the winding, leave a small piece free. It will protrude outward. In order to clamp it, there is a groove, which is the same on the inner surface of the coil. This groove secures the end of the line tightly and prevents it from unwinding when the spool is collected. If the reel design does NOT provide for this groove, then hold the end of the line with your hands yourself. The outside of the coil can now be attached. It also has a hole through which you need to thread the outer piece of your line. Now you can put the assembled coil back in place on the trimmer.

Now in coils designed to work with two tendrils. First you need to see how many line grooves there are on the reel. The presence of either one or two in different coil designs is provided. And then it already becomes clear how to wind it. Two tendrils at once in one groove, or # 8212; each antenna is separate. Please note that if there is one groove in your spool, then the line hole must be through. Now you need to rewind the fishing line about 2 4 meters and thread it into this through hole in such a way that the fishing line is the same on one side and on the other. Now look again, there will be an arrow indicating where to wind. Direction. Against the direction of rotation of the coil to the trimmer. Reel two tendrils of fishing line at once, together. We leave small ends. If there are special grooves. Clamp in them if not. We just hold it tightly with a hand, a finger. There will be two holes in the outer casing of the coil. Separate line for each end. To do, assembled the coil and put it on the trimmer.

If you have a reel with two grooves, then the unwound piece of fishing line (all the same 2-4 meters) must be folded in two, and in a special groove (it should be located just between the grooves), insert the line bend, that is, the middle, folding her in the form of a loop. As in the previous case, you need to reel both lines at once, only this time. Each with a separate groove. What next. As described above. Fixed, attached the upper body, attached the coil to the trimmer.

Another kind of coils. With a through hole on the inside. The outer case also has holes. That is, it turns out that the line needs to be passed through these holes both in the inner and outer parts, and immediately assemble the coil. And for winding, they use a button (this is the same button that is used to release the fishing line during operation). Only to wind the line now you need to rotate this button. over, the mechanism of this button is designed in such a way that it can be turned only in one direction, just the direction you need.

Line selection

For the trimmer to work like clock, you need to choose the right line, that is, choose it taking into account the trimmer model and the type of work. There are two fundamental parameters in this matter. This is the diameter and section.

The diameter of the fishing line must correspond to that recommended for this model (it must be indicated in the product passport). The cross-section of the fishing line is round, square, with sharp edges (pentahedron). A round line is designed for mowing young grass and lawn, square and pentagonal line will come in handy if the grass is hardened and weeds have grown on the lawn.

Trimmer head modification

Trimmer mowing heads can be of various modifications: single-string for trimming the lawn (mows with one line of line), two-string for mowing grass and Land clearing with automatic line feed or manual adjustment of the string length.

Modern growers are increasingly offering gardeners universal trimmers with two-line automatic mowing heads.

How to properly line the trimmer

What gasoline is needed for the trimmer. 2-stroke petrol trimmers

Mototrimmers 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 its mixture with engine oil. Remember that the oil must be special, designed for two-stroke engines. Using automotive engine oil can damage the instrument.

Trimmers with a two-stroke engine should be filled with AI-92 gasoline. Of course, it will be able to run on gasoline with a higher octane number. But when refueling with AI-95 gasoline, the engine will overheat and run unevenly.

Mix oil and gasoline in the correct proportion. If there is too little lubricant, seizures will appear on the surface of the piston and cylinder walls, then the piston ring will collapse, and the engine will jam. An overabundance 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, which will lead to a drop in power.

Usually the proportions of gasoline and oil are indicated in the instructions for the tool. Many manufacturers prescribe a ratio of 50: 1. One part oil is added to 50 parts of fuel. Therefore, there should be 20 ml of oil per liter of fuel. If the engine is worn out, or the tool is operated under high load, the amount of lubricant can be increased to 25: 1, pour 40 ml per liter of gasoline.

The grade of gasoline suitable for a particular tool model is usually indicated in the operating instructions. If you ignore the manufacturer’s recommendations and fill the tank with fuel with the wrong octane number, over time, the device may simply fail. Trimmers are available with two-stroke and four-stroke engines. Their refueling and maintenance are significantly different.

Petrol trimmers with four stroke engine

The trim tabs, powered by a four-stroke engine, are more complex. Gasoline and oil are poured into different containers, from where they are then fed to the engine. In such models, you cannot use a lubricant intended for two-stroke engines. Gasoline for a trimmer with such a motor must be AI-92 or AI-95. The use of fuels with a lower octane rating is not recommended. This will lead to unstable engine operation.

Many trimmer manufacturers insist on using fuels and lubricants produced under their own logo. They are often more expensive than analogues sold under other names. Is it worth overpaying for branded oil? Companies that make gasoline tools, not fuels and lubricants. They buy these products from firms that produce 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 matches the parameters of the engine.
