How to Dilute Gasoline To a Saw

The chainsaw is an indispensable assistant to owners of summer cottages and private houses. With its help, you can not only prepare firewood for the bath and barbecue, but also tidy the garden. Having decided to build a wooden structure on the site, you need to purchase this practical tool. The choice of a saw should be taken with all seriousness, as well as the observance of the rules for its operation. So the tool will last as long as possible. And for this you need to know how to dilute gasoline for a chainsaw.

Fueling principle

Before starting the saw, dilute the fuel mixture and fill the tank with it. To visually control the fuel level, the walls of the fuel tank are made translucent. Thanks to this, the owner sees that it is time to refuel the tank. This must be done carefully so that the fuel mixture does not spill. No need to fill the tank to the brim, let there be some free space left.

A domestic-made saw, such as Friendship or the Urals, can be refueled with a mixture containing A-76 gasoline. But for the import (Partner, Husqvarna, Stihl, Champion) you need to use only 92 brands. Shake the mixture before refueling the fuel tank.

Engine power system

As you can see in the photo, the fuel system consists of the following elements:

  • Tank for fueling;
  • Fuel filter that prevents foreign particles from entering the system;
  • Carburetor
  • Pre-fuel pump.

Chainsaws with a capacity of 2 kW have a fuel tank, which holds about 500 ml of fuel. With such a quantity of gasoline, they can be operated at full power for about 30 minutes, since the flow rate is 1.2 l / h. The smaller the tank volume, the less time the saw will work on one tank refueling. Along with the fuel tank, the oil tank should also be filled. Oil is poured there to lubricate the saw mechanism.

Tool manufacturers Stihl, Husqvarna, Partner, Champion produce special lubricant compositions for saws that contain impurities that allow them to stay on the chain for a long time. The cost of the branded mixture is quite high, so the owners wanting to save money use the usual engine oil instead. Maybe this is not a good option, but there are no special negative consequences of such a replacement. The downside can be considered a more significant expense, but comparing the cost of the disadvantage does not seem significant.

If we compare the consumption of fuel and oil tanks, then the production of lubricant does not occur as fast as fuel. When the gas has run out, very little content should remain in the oil tank. This indicates a properly adjusted system. Any deviations signal that you need to check the operation of the engine and carburetor and, if necessary, carry out repairs and replace parts.

How to dilute

In order for the saw to serve for a long time, it is necessary to use only high-quality fuel. You can dilute the fuel mixture yourself. To do this, you will need two components: gasoline A-92 or A-95 and a special two-stroke oil. If the fuel is clear, then the choice of lubricant may raise questions.

The proportions in the gasoline-oil mixture are very important. For tools with power up to 1.5 kW, the ratio of lubricant to gasoline is applied 1:40, for more powerful. 1:30 and 1:20. Information about the exact proportions can be found in the instructions for the tool.

The mixture should be diluted in a dry container made of metal or antistatic plastic. Conventional plastic containers are not recommended for such purposes, as the resulting static electricity can cause a fuel to ignite. The lack of moisture on the container is a very important and fundamental condition.

After adding the components of the mixture, close the container tightly and shake the contents well to obtain a homogeneous mixture. The fuel prepared in the correct ratio should be used up within a month. Longer storage leads to oxidation of the composition, which makes it unsuitable for refueling the chainsaw in the tank. If fuel remains in the tank after work, it should be drained.

Fuel tank

To avoid unpleasant surprises, it is necessary to follow the rules of refueling a fuel tank, namely:

  • Do not fill the tank near an open flame, do not smoke near the saw;
  • The holes for filling the tanks should be directed upwards, be clean and dry;
  • The tank covers must be unscrewed carefully so that the remaining fuel does not spill;
  • It is convenient to fill the tank with a combustible mixture using a funnel. Both oil and gasoline should be poured slowly and carefully;
  • After refueling, screw the covers all the way and lock. This will protect against accidental unscrewing;
  • Each time, check the tightness of the tank. If it proceeds to work with the saw is dangerous and strictly forbidden;
  • Do not start the saw directly at the gas station. Need to move a few meters.

Compliance with the operating rules makes working with a chainsaw as safe as possible, whether it be Friendship, the Urals or foreign-made tools. By listening to the recommendations of this article, you can extend the life of the tool and save on repairs.
