Chainsaw gasoline dilution ratio

Let’s start with the engine

Engine care includes blowing out the cylinder cooling fins, checking the spark plug, oil, fuel and air filters.

The air filter and cylinder cover must be removed to clean the cylinder fins. When refitting the cylinder cover, check that the wires of the switch and the sealing ring are in the correct position.

To clean the fuel and oil filters, you need to remove them and rinse them with gasoline for chainsaws, or replace with a new filter.

It does not hurt to check the spark plug periodically. In case of contamination, clean the electrodes with a wire brush and restore the gap to 0.65 mm.

To check the air filter, we take it out, remove dust from the surface. If it is heavily clogged, then it is better to rinse it in gasoline.

If cleaning with compressed air, direct the jet towards the inner surface.

Chainsaw care. engine, chain, tire

Before moving on to the topic of caring for a chainsaw, it is worth talking a little about the safety of use. The FUBAG FPS 56 model selected as an example is equipped with a chain brake that prevents the chain from rotating in the event of a kickback. Always check that the chain brake is working properly before starting work.

How to do it? We start the saw at full speed for a couple of seconds and press the protection lever. The chain must stop immediately. If this does not happen, but you need to contact the service.

The chain brake is easy to check with the engine off. It is enough to hit the end of the tire on a hard surface, the protection lever should automatically fold back. Remember? Moving on.

Correct use guarantees the correct operation of the tool for many years. After each working session, it is advisable to clean all the elements in order to get rid of accumulated dust.

Chainsaw chain maintenance

During operation, the chain stretches and does not fit well on the saw teeth. If the chain nuts are too loose on the saw teeth, then tighten the chain and then tighten the blade itself. When the chain is worn out, you need to change it, but first you can try to sharpen it.

Learning about link wear is simple:

  • Sawdust becomes powdery
  • It takes more effort to work
  • The saw vibrates strongly
  • Fuel consumption increases

You will need a file to sharpen the chain (Fubag already has it in the kit). Having prepared the tool, you can get down to business:

Lock the chain in place
2. Take a round file of the appropriate size
3. Place the file on the bit and start sharpening, keeping it straight.
4. After sharpening each cutter, measure the depth and bring to the desired size.
5. To minimize the chance of kickback and link breakage, round off the leading edge.

TEST # 2.Check the chain oil supply

With the engine sorted out. Now let’s evaluate the correct supply of chain oil.

To do this, after starting the engine, run the chain at medium speed to remove excess oil. If necessary, adjust the feed with a screwdriver. It is necessary to insert it from the underside of the coupling and set the desired oil flow.

Assembling a chainsaw using the example of Fubag FPS 56

Like most analogues, the chainsaw is supplied unassembled: a body, a separate tire and a saw headset. In addition to the main parts, the kit includes: a set of tools, a container for gasoline mixture, a tire cover, a bumper, a file for sharpening a chain and reliable safety goggles.

Everything is clear with the kit. let’s move on to the assembly:

Move the guard towards the front handle to make sure the chain brake is disengaged.

Loosen the nuts and remove the chain cover.

Install the cutting link (for the FUBAG FPS 56 chainsaw it is included in the kit).

We turn the chain on the sprocket, and at the same time install the tire on the saw body.

Check if the direction of rotation of the saw chain is correctly set.

Install the chain cover on the main saw body and tighten the nuts by hand.

Adjust the chain tension by turning the tensioning screw until the connecting link touches the underside of the guide.

Raise the end of the tire and finally tighten the nuts.

Manually check the uniformity of rotation and the degree of saw tension.

If the chainsaw has a gas-powered tensioning system, as, for example, the FPS 37 saw model, then the assembly process will take no more than a minute. For this you need:

Position the bar and chain on the chainsaw pins in the correct way (the cutting teeth must point in the direction of travel).
2. Install the cover. For correct installation of the cover, adjust the position.
pins on it so that they go into the holes of the tire.

Extend the screw stop and tighten a little until the bar and chain do not dangle, but there is some freedom to adjust the chain tension.
4. Adjust the chain tension by rotating the wheel.

Pull out the stop and tighten the cover, ensuring reliable fixation of the equipment.

It is not necessary to tighten the chain all the way, because soon it can stretch again. The chain should have a small margin, slightly sag. It is not difficult to check with your hand. Ideal if it lends itself to bend off the tire by a millimeter.

TEST No. 1. Checking the supply of the fuel mixture

Our saw is fueled. Let’s start the engine and test the oil flow.

How to make the fuel mixture Salemmaster chiansaw

We check the caps of the gas tank and oil tank. They must be tightly closed.
2. This model has an easy start system and a primer. a fuel pumping button. Pull out the air damper handle and turn on the ignition switch.

Pull the recoil starter. Important! In this case, the saw should not be in hand, only on the ground! This is necessary to avoid injury when jerking.

Let the engine run for 30-40 seconds at idle, after which the air damper can be moved to its original position.

The saw is ready to work, press the start levers. This model is equipped with an anti-vibration system, which significantly reduces the burden on the operator. To stop the saw, simply release the start button. The chain will stop and the engine should be idled for a few minutes. After that, turn the ignition switch to position O.

In what proportions to mix oil and gasoline for chainsaws?

The chainsaw is equipped with a single-cylinder two-stroke engine that uses a fuel mixture for operation. To refuel, you will need 92 gasoline and a special oil for air-cooled two-stroke engines.

Prepare a mixture in the proportion of oil and gasoline. 1:40. In other words, we observe the ratio per 1 liter of gasoline. 25 grams of butter. Most often, such a volume is contained in a standard cap of a container with a technical liquid.

Mix the mixture well in a separate container. Owners of FUBAG FPS 56 are in luck, because it is already included in the kit. After completing the preparation of the fuel mixture, pour it into the gas tank.

Which chainsaw oil to choose? For our engines, we recommend Fubag 2T Extra semi-synthetic oil. optimally selected quality composition. Please note that oil for four-stroke engines or for outboard motors will not work in any way.

READ  Partner Chainsaw Oil Pump Replacement

Chainsaw fuel mixture isn’t the only one that uses oil. The devices have one more technological tank, where the lubricant for the chain is poured. By the time the fuel runs out, the chain oil also runs out, so it will need to be refilled every time after refueling.

How to choose chain oil? We recommend the special brand Fubag Super Chain oil.

Chainsaw tire care

The tire is an important part of the chainsaw. It is on its serviceability that the performance and quality of the device largely depend.
The tire needs regular cleaning.

To clean the tire you need:

  • Remove the guide bar and remove wood dust from the bar groove
  • Clean lubrication hole
  • Provide lubrication to the front of the gear train from the hole at the end of the bar

Check for oil leaks. Check the tightness of the fasteners and the integrity of the main parts, the working condition of the handle connections and the fastening of the guide bar. Only then get to work.

To prevent the tire from wearing out, it must be turned over from time to time. The guide must always have a perpendicular profile. If the tire still needs to be changed, then use the tire with the parameters recommended by the saw manufacturer. This will extend the life of both the saw headset and the entire saw.

The sprocket should also be checked periodically for cracks and signs of wear. If they are found, the part must be replaced. Putting on a new chain on a worn out wheel, or vice versa, is not allowed!

Butter

According to the international classification, oils of the following markings are used for chainsaws:

  • API-TB;
  • API-TS;
  • JASO-FB;
  • JASO-FD.
  • Use oil for 2-stroke engines only;
  • Do not use the material after the expiration date;
  • It is strictly forbidden to add working off (it contains many unnecessary impurities. harmful to the central mechanism of the chainsaw);
  • You can not use chain lubricant (for each device: chain and engine. it is its own);
  • It is preferable to use synthetics or semi-synthetics (during development, it almost does not form combustion products, but the price of such material is higher than that of mineral oils).

Formula

  • High-quality fuels and lubricants;
  • Correct proportions;
  • Mixing tools and technology.

Technology

Not only the quality and proportion of fuels and lubricants is important (although it is dominant in this matter), but where and how (how) gasoline is diluted with oil for chainsaws.

The technology provides for the use of containers with graduated marks, some brands (along with chainsaws and oil) produce containers for mixing and storing fuel. Made of special non-combustible material, they are produced in the form of a canister or bottle, often endowed with measuring lines, and some of them have two entrances (separate for each type of fuel and lubricants).

Often, improvised means are used for mixing:

  • Plastic / glass bottles;
  • Syringe (no needle);
  • Measuring cups;

When using household products, be extremely careful, because during the mixing process, when combustible material interacts with the surface of non-specialized containers, static electricity can be generated. this is fraught with an explosion. When making a mixture, oil is added to gasoline, since it has a higher density.

How to dilute gasoline with chainsaw oil

The surest solution is to follow the recommendations specified in the instructions for the product! In the absence of such an opportunity, you can use a special fuel preparation formula.

Proportions

There are several options for the ratio of fuel and lubricant. As a rule, this number ranges from 20 to 50 ml of oil per 1 liter of gasoline.

Again, you must follow the instructions for the product or the recommendations indicated on the oil label (priority of the instruction). In the absence of such, before diluting gasoline, you need to pay attention to the power indicator of the product, since the created proportion directly depends on it.

For chainsaws with power:

  • Up to 1.5 kW, the recommended ratio is 25 ml of oil per 1 liter of gasoline;
  • Above 1.5kw 20ml / l.

In gasoline for a chainsaw, it is allowed to add oil a little more than the recommended proportions (up to 5 ml per 1 liter). In this case, you should be extremely careful, because non-observance of the proportions can lead to breakdown, and as a result, expensive repairs.

If gasoline is diluted with a large volume of oil, then during operation the number of shock loads on the cylinder-piston system will be increased, and carbon deposits may also form, as a result of which the CHP will fail.

The addition of a small amount of oil to gasoline for a chainsaw can lead to insufficient lubrication of the surfaces of moving elements, which will lead to additional friction of the elements and their heating, followed by the destruction of the entire mechanism.

Petrol

According to experts, it is necessary to use unleaded fuel with an octane rating exceeding 90. Gasoline A92 and Ai92 is considered ideal. You can use the 95th, but there is an opinion that it is better to refrain from this kind of gasoline, since some of them are made on the basis of the 92nd with the addition of additives. The latter, in turn, are harmless for 4-stroke car engines, but they will be superfluous for the “sensitive” mechanisms of 2-stroke motors.

It is recommended to use fresh gasoline for chainsaws, since when stored in cans the fuel can lose its octane properties.

Fuel quality

If you want the tool to do its job perfectly and serve for more than one year, you must provide it with fuel and lubricant of the proper quality.

Storage

It is recommended to dilute the fuel in a small amount without excess. It is impossible to store such a mixture for a long time (the properties of gasoline are lost), up to a maximum of 25-30 days. At the end of the work, it will not be superfluous to drain the remaining fuel and idle to work out its resource. This is due to the fact that storing the mixture in the product tank increases the wear of the seals.

Remember, the use of high-quality fuel and compliance with the manufacturer’s recommendations guarantees a long and fruitful operation of the product.

Shelf life of ready-made fuel mixture for chainsaws

So, pure gasoline can be stored not very long, and the ready-made fuel mixture is even less. Some manufacturers indicate that in a diluted state, storage up to one month is allowed.

But experts recommend storing no more than 8-10 days.

It’s just that as soon as you mix, the oil immediately begins to gradually lose its properties. As a result, after a few days this fuel mixture is not the same as it was originally. What can we say about storage for more than a month.

Therefore, do not prepare the mixture for future use. You need to cook as much as you are going to use for the upcoming work. How much needs to be prepared in this case, only experience can tell. If you still do not have enough of it, then prepare no more than one liter of the fuel mixture. If it is not enough, then cook some more. it will not take long. If it remains, then it will not be such a large number as to regret it.

Store the ready-made fuel mixture in a closed opaque container. Or, if the container is translucent, then put it in a dark place. The container must be petrol resistant. For example, plastic bottles from various drinks (“poltorashki”) will not work. Their plastic is eaten away by gasoline and all this stuff gets into the engine.

You can use special metal or plastic canisters for flammable materials. Or just use an empty canister from any used oil, having previously rinsed it from the inside with clean gasoline several times. Glass containers will work too, but keep in mind that they are easy to break.

What oil to use?

The oil, as already mentioned, should be for two-stroke engines. over, it should be suitable specifically for chainsaws, as indicated on its packaging. There are just two-stroke oils, for example, purely for boat motors or scooters. They should not be used, since the operating mode of such equipment is not so intense, therefore, the requirements for oil are somewhat lower.

At the same time, there are oils where it is indicated that they are suitable for both chainsaws and boat motors and scooters. This oil can be used. But if it is only for boat motors or scooters, then it is impossible.

READ  Where To Pour Oil Into A Chainsaw

Oil color

Two-stroke engine oil is usually red, blue or green in color. This does not affect the operational properties in any way. The dye is added only so that in the future you do not confuse the gas-oil mixture with pure gasoline and pour it somewhere where it should not be poured.

What gasoline to use?

It is better to use AI-92 gasoline for modern chainsaws. It is better not to use the 95th. Firstly, because the saws are set up to work with 92 gasoline. And, secondly, 95th gasoline is obtained by adding special additives to gasoline with a lower octane number. And as experts say, this is not good.

In general, fill in 92nd gasoline and you will be happy. Just do not stock up on it, as its octane number drops during long-term storage.

In general, they say (they say!) That our refineries can produce only 80th gasoline in pure form. But already it is brought to the 92nd and 95th due to additives. In 95, there are naturally more additives. So, during long-term storage, these additives “evaporate” and gasoline again becomes 80th. True or not. I don’t know, but I learned this information back in 2009 at one of the seminars on servicing gasoline equipment from the head of the service department in Russia of one of the manufacturers of gasoline equipment. If this was true, then maybe today (2018) the situation has improved.

In any case, it is better to buy gasoline at proven gas stations, where you have already refueled and everything was fine.

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. Even though there is soot with it, there is not so 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.

Oil producers

One of the best oils, admittedly by most experts, is produced by Stihl, the same one that also makes chainsaws very well. Therefore, if you have an expensive chainsaw, then it is better not to save by buying cheaper oils.

Another major global chainsaw manufacturer, Husqvarna, also produces a two-stroke oil of the same name. But many users noted that when it is used on equipment of other brands, it leads to excessive smoke, and in general chainsaws do not work at full capacity. At the same time, Husqvarna equipment itself works perfectly with this oil. Therefore, if you have a Husqvarna chainsaw, then buy the same oil for it. For other equipment, it is better not to take.

There are also well-known world brands producing various malas, including two-stroke ones. For example, Ravenol. Oil from such manufacturers can also be bought without fear.

There are oils produced in Russia. In principle, they are not bad if the saw is used for domestic use. That is, it will certainly somewhat reduce the resource of the chainsaw, but in everyday life you will not notice this, since the engine of the chainsaw, in any case, in such gentle operating conditions, serves for many years. For professional activities, I do not recommend taking such oil.

Correct proportions

So, I will not beat around the bush for a long time, but I will go straight to the numbers. The most common dilution ratios are 1:50 and 1:40. That is, one part of oil is poured into 50 or 40 parts of gasoline. For those who did not understand, I will explain in more detail. We take one liter of gasoline and divide it by 50 or 40, respectively. As a result, we get the right amount of oil for one liter of gasoline. That is, one liter is 1000 ml. Divide 1000 ml by 50, we get 20 ml of oil. Divide by 40, we get 25 ml. This is exactly how much oil you need to add to one liter of gasoline.

But you will say that you do not know what the proportion should be on your chainsaw. Well, if you have lost the instruction or for some reason there is no information about the proportion in it, then you can use the following rules:

  • if the chainsaw and oil are from the same brand (for example, Stihl chainsaw and Stihl oil), then dilute gasoline with oil in the proportion indicated on the oil (usually 1:50);
  • if the chainsaw and oil are of different brands, then observe the ratio of 1:40;
  • if the brand is the same, but there is no information on the oil, then dilute in a ratio of 1:40;
  • if nothing is known at all. you do not know the brand of the chainsaw or the oil., then you still dilute in a ratio of 1:40. The main thing is to know that the oil is exactly suitable for two-stroke engines of chainsaws.

If the saw is new and runs in, it is recommended to increase the amount of oil for the first three fuel tank fillings by about 20%. That is, the proportion of 1:50 turns into 1:42, and 1:40 into 1:33. Or 24 or 30 ml of oil per 1 liter of gasoline, respectively. Well, I note here that in addition to increasing the amount of oil in the fuel mixture, no more running-in measures with a chainsaw need to be carried out, unless otherwise indicated in the instructions. That is, it is not necessary, for example, to leave it idling for a long time or to cut it not at full speed, as this will lead to its overheating and faster failure. Always cut only at maximum speed. And after running out of three tanks of fuel (meaning the tank of the chainsaw), go to the usual proportions of 1:50 or 1:40.

But sometimes it happens that the manufacturer indicates a different proportion, compared to those that I gave above. For example, 1:25 or 1:32. In this case, these proportions must be observed. Although if you know about them, then what did you forget in this article?

How to properly breed?

The numbers of dilution proportions are not in vain given with such accuracy. That is, it does not say that “take approximately this amount of oil.” The exact proportion cannot be observed by eye, so you have to use something that will allow you to measure the exact amount of oil and gasoline.

Some inexpensive chainsaws usually come with a measuring tank with risks. As a rule, it has several scales for different proportions. Or one, if the manufacturer implies that this tank will only be used with the saw with which it comes in the kit. There should be two horizontal marks on this scale. The lower one shows the level to which you need to pour gasoline. Upper. the level to which the mixture should reach after adding oil to gasoline.

How to mix fuel for chainsaw

For more accurate metering of oil, you can use a medical syringe. Preferably not less than 20 ml.

In general, pour gasoline into a measuring container, add the required amount of oil measured with a syringe and shake.

Preparation of the mixture must be done in a separate container, and not directly in the tank of the chainsaw. Otherwise, the oil, without having time to dilute with gasoline, can get into the carburetor, which will complicate starting, up to the need to remove the carburetor and clean it.
