Preparation of fuel mixture: proportion of oil and gasoline for chainsaws

Engine Chainsaws is the "heart" of the tool, so it is very important to use a properly prepared fuel mixture.

Fuel mixture for chainsaws Prepared from two components - oil and gasoline. Chainsaws are equipped with two-stroke engines, so oil is added not to the lubricant system (like a four-stroke engine), but directly to gasoline. At the same time, it is very important to observe the correct proportions of the ingredients, of course, in no case try to work on pure gasoline, because in this way you will quickly "kill" a chain saw.

Oil must be intended for two-stroke engines of gardening and forest equipment (That is, in no case cannot use oil for boat engines or scooters). As practice is shown, this can be bought in any store or service center, where there are chainsaws or maintenance of the latter.

If we talk about what gasoline to fill in chainsaw, it will be optimally used fuel with an octane number A-95In this case, the savings on the stuff can turn into deplorable. Often, European manufacturers indicate that gasoline A-90 or A-92 can be used, but in the post-Soviet countries the quality of gasoline is inferior to European, so in our realities it is better to use better gasoline.

As for Samoa the proportions of the benzo-oil mixtureHere everything is simple: you need to follow the instructions for the instrument. All indicate the necessary relationship in the operating manual or in the instrument passport, in addition to the proportion for refueling, chainsaws may differ depending on the chain saw model. As a rule, the proportion of oil and gasoline to the chainsaw of eminent producers is a ratio of 1:40 or 1:50, which means 1 part of the oil on, for example, 40 parts of gasoline. Now arithmetic 1 l gasoline \u003d 1000 ml of gasoline, divide by 40 and get 25ml oil. If you perform the same actions to the ratio 1:50, then we get 20 ml oil on 1 liter of gasoline. As for budget chainsaw of Chinese production, the situation is slightly different. The ratio of gasoline and oil for chainsaws made in China. 1:25, that is, 1000ml gasoline divide on 25, we get 40ml oil. The thing is that in branded chainsaws, the strong assembly and the distance between pistons and cylinders in the engine is much less than that of Chinese chainsaws, therefore the required amount of oil differs almost twice.

In order to measure the proper portion of the oil, use the usual medical syringe sufficient volume.

Another subtlety - In a dry canister for gasoline, first pour gasoline, and then oil. The procedure on the contrary is fraught with a low-quality fuel mixture, because the oil is more denser, the canister sticks to the bottom - what is good mixing here.

Be sure to prepare the fuel mixture in the canister and pour into the benzobak already ready-made special curtain! Never cook and do not mix it directly in the fuel tank chainsaws!

If with the question how to breed gasoline for chainsaws, then on the conditions of storage and timing of the fuel mixture It is worth saying a few words. It is best to prepare a benzo-oil mixture to 1 liter of gasoline, it is recommended to do it immediately before work with the tool. Fuel tanks chainsaws have a volume from 0.3 to 1 liter. Under household conditions, one session is rarely used by the entire volume of cooked combustible mixture, so the residue can be saved until the next session. Store the fuel mixture is necessary in a special canister for gasoline, in a dry dark place. Optimally expect that the shelf life of the finished mixture will be 7-10 days. The fact is that the oil presented now on the market is not synthetic, but organic, that is, natural. After 10 days, all lubricants are lost, gasoline simply "eats" oil. Naturally, it is impossible to use such a fuel, it can cause a breakdown and failure of chainsaws.

At the end of the work, it is necessary to drain the fuel mixture, start a chainsaw, the tool will stall (so that the saw has a dry carburetor) and now you can leave it until the next session of operation.

Unsuitable fuel mixture must be disposed of.
