The ratio of gasoline and oil for the Partner chainsaw

Petrol

The main component of the fuel mixture for chainsaw engines is gasoline with an octane number of at least 92. Consumables with expired storage, made on the basis of gas condensate, which have water and mechanical impurities in their volume, are not suitable for the preparation of fuel.

  • The opinions of experts on the use of gasoline of different brands are ambiguous. On the one hand, the incomplete compliance of domestic gasoline A-92 with European standards is recognized.
  • On the other hand, the quality of A-95 gasoline is questioned due to the high content of anti-knock additives. It is possible to use this fuel for the preparation of fuel for a chainsaw only with full confidence in its quality.
  • The difficulty lies in the presence of various improving additives, with the help of which unscrupulous manufacturers and distributors increase the performance properties of motor gasoline with a lower octane index.

Also, irreversible changes in the working properties of the fuel occur when it is stored for a sufficiently long time in a plastic container, regardless of the level of its petrol and oil resistance.

Why you need to observe the proportion of gasoline and oil?

Many buyers, when purchasing a chainsaw, are perplexed why the oil with gasoline recommended by the manufacturer should be added in the exact amount. It’s all about the intricacies of a two-stroke engine, which differs from its 4-stroke counterpart in a number of specific design solutions.

One of them: the manufacture of a single-cylinder engine, in which there is no crankcase for filling with lubricating consistencies. This is seen as the technological success of its time.

You can imagine how the incoming combustible mixture loses oil molecules, which are deposited on the cylinder stacks. Subsequently, it creates a sliding protective film in the rubbing units and parts of the internal combustion engine, reducing the physical contact of the piston rings with the wall of the cylinder, connecting rod and crankshaft.

To provide the unit with maximum performance, long-term operating conditions are achieved by the correct ratio of pure gasoline to the recommended oil. Violation of the rule guarantees a quick exit of the instrument from the functional state. ICE breakdown will require significant funds for repair or replacement with a new analogue.

Many users of mechanized hand tools consider the oil reservoir present in the unit as a reservoir for lubrication and a power plant. This is fundamentally wrong. The lubricant is designed for the chain during operation. Only. The oil reservoir is a priori not connected by the pipeline with the engine.

Depending on what power is required to be obtained from the units, the appropriate component dilution is selected:

In one liter of fuel, 40 to 50 parts of oil are diluted. These are the ideal proportions of gasoline and oil.

Along the way, we inform you that only unleaded gasoline of the AI-92 or AI-95 brands is used. Leaded combustible product is considered a poor choice for internal combustion engines, as it shortens the engine’s service life.

Features of running in a new tool

This concept includes the gentle operation of the chainsaw at the initial stage of its operation. The technology also provides for the operation of the engine on a mixture with an engine oil increased by 20%.

The running-in time in engine hours is indicated in the attached instructions. In practice, for the tool to reach the working level, it is enough to generate 3-5 refills of the saw’s gas tank.

New models do not need running-in, but the first hours of operation are not recommended for the chainsaw to be used with heavy loads.

Step-by-step instructions for refueling

If you want to refuel your chainsaw, you need to follow a simple algorithm:

Features of preparation and storage of the fuel mixture

Safety regulations prescribe to dilute gasoline and oil in a metal canister. This eliminates the risk of static electricity and fuel ignition.

Experts advise to pour oil into an incomplete container, mix thoroughly, and then top up with clean gasoline to the specified level. Saving working time by preparing the working mixture directly in the gas tank of the chainsaw should be excluded from everyday practice.

This technology is fraught with fuel system failures due to the ingress of a large amount of oil into the carburetor, the need for disassembly and thorough flushing.

Why gasoline is mixed with oil for refueling chainsaws

It is necessary to dilute gasoline with oil in order to avoid the failure of the internal combustion engine. The reason for this is the design features of the lubrication system for two-stroke motors. In the design of such engines there is no chamber for filling engine oil, and if you fill in fuel without lubricant, then the crankshaft, piston, bearings and connecting rods will not receive lubrication. This will significantly reduce the service life of all the listed parts, therefore, it is prohibited to fill in clean fuel.

Gasoline and oil for the chainsaw must be poured in the appropriate proportions, which makes it possible to effectively lubricate the rubbing parts. Lack of lubricant or its excess will lead to negative consequences in the form of carbon deposits. In order for the tool to work properly, from the first day of operation of the tool, it is necessary to fill it not only with high-quality materials, but also observe the correct proportions.

For the engine to work properly, the main thing is to fill it with clean fuel without contamination.

Chainsaw refueling instructions

Knowing the ratio of the preparation of the petrol-oil mixture, you can start refueling it. Refueling instructions are as follows:

  • First you need to prepare the mixture. Having combined the two main components, you should mix them thoroughly.
  • Place the tool on a clean and level surface. Before unscrewing the gas tank cap, it is necessary to clean or blow off sawdust, dust and dirt.
  • The filler neck must point upwards.
  • Install a small watering can in the neck, then pour fuel
  • Control the refueling process, as the volume of the tank is small, so it fills up quickly
  • Do not fill up to the full maximum, since when the tank cap is closed, the remaining fuel will splash out.
  • After the fuel is poured into the tank, immediately add chain lubricant.
  • Fuel consumption and chain lubrication are approximately the same, therefore both tanks must be filled at the same time.
  • After refueling, you can start starting the engine.

It is better to start the engine not in the place where the refueling was carried out, but to move to a distance of 2-3 m. The tool is ready for work, and you can start to start it. How the chainsaw engine starts, you can read in this material (link).

What happens if you pour working off into a chainsaw

If you do not want your chainsaw to fail at the wrong time, use only high-quality fuels and lubricants. It is forbidden to mix working off with gasoline. The reasons for this are the following factors:

  • Other viscosity of the material, therefore, mining is not able to provide effective lubrication of rubbing parts and mechanisms
  • The mining contains small particles of metal and shavings, which, getting into the tank, will cause clogging of the fuel filter and channel. If the grease enters the cylinder together with small particles, they will leave their imprint in the form of accelerated wear of the piston rings.
  • Emitting a lot of black smoke, which indicates burning of oil

It is impossible to pour surrogate materials not only into the gasoline tank, but also into the chain lubrication tank. What happens if you use the development in the tank for chain lubrication can be seen in the video.

Using the instructions, you can independently prepare the correct fuel mixture on which the chainsaw will work. If the fuel mixture is diluted incorrectly, not only will the tool life be reduced, but also its performance will decrease.

Gasoline and oil for chainsaws. which is better

Often beginners ask, which one is better to take gasoline for their instrument? In order not to make a mistake in the choice, it is recommended to read the instructions for the tool. In the instructions, each manufacturer indicates the corresponding brand of fuel. If the manufacturer indicates that the octane number should not be lower than 95, then it is not recommended to pour 92 gasoline.

Motor oils for two-stroke engines are produced by the following manufacturers:

Usually, the ratio is indicated on the lubricant bottle, so it will be difficult even for beginners to get confused with the preparation of the fuel mixture. Do not under any pretext use the working off even as a chain lubricant. This will lead to the fact that soon it will be necessary to repair the tool.

Finished fuel cannot be stored for more than 25-30 days, because the oxidation process changes its composition. Engine breakdown caused by overexposed fuel is considered non-warranty. The amount of repairs reaches 80% of the cost of a new chainsaw. After the end of the working season, use up the remaining fuel, turn off the engine, remove the remaining fuel mixture.

Remember, your goal is to create a mixture that will ensure smooth operation of the engine, complete combustion of fuel without the formation of deposits, smoke or scuffing.

How to properly dilute gasoline for a chainsaw

What to mix? On sale are canisters with graduated marks and two holes. for oil and gasoline. Pour in ingredients, screw on lids and stir by tilting the bowl.

Many people use glass and plastic bottles, baby horns and syringes. Be careful with glass and plastic for static electricity. Make sure that no solid particles or water droplets get into the mixture. Be sure to stir the mixture thoroughly.

How to pour gasoline into a STIHL chainsaw?

The work of any chainsaw, a wide selection of which is presented at zakazik.ua/products/benzopila.html. provided by a 2-stroke engine, the design of which does not imply the presence of an oil pump. That is why only a mixture of gasoline and oil is poured into them. It is strictly forbidden to use gasoline in its pure form.

Mineral or synthetics?

Yes, just like for cars, there are both mineral and synthetic oils for chainsaws. Due to the lower price, in most cases, mineral oil is used. However, synthetic provides a longer service life of the chainsaw, since no carbon remains on the cylinder walls with it.

But don’t be afraid of mineral oil if you can’t get a synthetic one. Although there is carbon deposits with it, there is not much of it. However, the service life of the saw with such oil will be slightly lower (but not catastrophic).

What you just can’t do is start using synthetic oil after you have used mineral water on your chainsaw for a long time (more than 100 hours). This is due to the fact that synthetics will wash away the accumulated carbon deposits and it can get in pieces where it is not needed. Therefore, if you initially started using mineral oil, then use only it.

Quality components needed

Practice proves the influence of the quality of the prepared mixture, taking into account the required proportions, on the service life of the tool, power, productivity:

  • It is not recommended to use components that have reached the end of their shelf life.
  • It is especially important for the constituent parts of gasoline and oil. do not use components obtained on the basis of gas condensates, since the molecular structure contains harmful ones, for the internal combustion engine, add water.
  • Partial non-compliance of AI-92 with international standards. AI-95 grade is saturated with additives that damp the detonation moments of the internal combustion engine.

Gasoline and oil for the chainsaw must be poured in the appropriate proportions, which makes it possible to effectively lubricate the rubbing parts. Lack of lubricant or its excess will lead to negative consequences in the form of carbon deposits. In order for the tool to work properly, from the first day of operation of the tool, it is necessary to fill it not only with high-quality materials, but also observe the correct proportions.

For the engine to work properly, the main thing is to fill it with clean fuel without contamination.

How much oil should be poured into gasoline in milliliters? Calculated per ml, the proportion of oil and gasoline 1 to 50 is 20 ml per 1 liter. To prepare the correct mixture, you should fill 1 liter of gasoline in a plastic bottle and dilute it with 20 ml of oil. To correctly measure how much oil to pour, you should take a special measuring container and fill it up to the appropriate mark. If you plan to immediately prepare 2 liters of fuel, then 40 ml of lubricant must be added to this amount of gasoline.

There are other ratios that different manufacturers offer. These values ​​of the ratios differ insignificantly, but if you have subtracted other values ​​in the instrument’s passport, then you need to adhere to them. A value of 1 in 50 or 40 is standardized. Pour 15 ml of oil into 1 liter of fuel in the summer, and in winter, add at least 20-25 ml. Knowing the recipe for preparing the mixture, you should also figure out what kind of gasoline to pour into the chainsaw?

Advantages and disadvantages of the Partner 350 chainsaw

  • easy start;
  • high power;
  • affordable and easy service;
  • unpretentiousness in the fuel mixture and lubricating oil;
  • high-quality assembly;
  • durable plastic case;
  • strong and reliable tire;
  • durable chain.

The main malfunctions of the chainsaw and their elimination

  • the engine of the chainsaw was started incorrectly;
  • the proportions of the mixture in the carburetor are not preserved;
  • dirty spark plug or fuel filter.

To understand where the cause lies, try disassembling your Partner 350, checking your chainsaw settings, and fixing any problems you find.

If your chainsaw is not running at full power or is unstable, try replacing the spark arrester, cleaning the air filter, or adjusting the carburetor. How the carburetor is adjusted correctly can be seen in the video below.

In the case when the chainsaw is unstable, intermittently, and a strong, smoky exhaust is emitted during operation, then, most likely, you have not correctly observed the fuel to oil ratio. Try replacing the fuel mixture with a new one.

Important conditions

The power plants in chainsaws are internal combustion engines fueled with certain brands of gasoline diluted with the required parts of oil.

Knowledge and strict adherence to the preparation of a combustible mixture is the key to long-term operation, productive use of small-scale mechanization units.

The main fuel component is the AI ​​grade. It is not recommended to use below or above 92 octane number. Optimal for many types of mechanized sawmills of domestic or foreign manufacture.

The ideal ratio of gasoline to chainsaw oil:

  • increases the performance of the unit;
  • increases the service life;
  • saves money.

Why you need to mix oil and gasoline

When using the saw, gasoline should always be mixed with oil. The reason for this is the design features of a two-stroke internal combustion engine. It does not have a dedicated lubrication system for parts (as in other internal combustion engines) and, accordingly, its cylinders with O-rings, crankshaft, bearings and connecting rods must be lubricated directly in the process of obtaining fuel.
