Chainsaw. first launch: assembly, proportions of oil and gasoline, care and storage

How to prepare a chainsaw for the first launch? How to prepare the correct fuel mixture and quickly change the headset? In this article, we will answer these and many other questions, as well as give some tips on maintenance and storage of a chainsaw.

A popular model will help to describe the main stages of tool assembly Fubag fps 56 chainsaws with a running engine for 2.5 kW.

Like most analogues, the chainsaws are delivered in disassembled form: case, separately tire and saw set. In addition to the main parts, the kit includes: a set of tools, a container for a gasoline mixture, a tire cover, a tire emphasis, a sawing file and reliable protective glasses.

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

We shift the protective casing towards the front handle to make sure that the chain brake is turned off.

Weaken the nuts and remove the chain casing.

Install the cutting link (for the fubag fps 56 chainsaw it is included).

four. Turn the chain on the chain wheel, and at the same time install the tire on the saw housing.

We check whether the direction of rotation of the saw chain is installed correctly.

She saw an alien. (HELP)

Install the casing of the chain on the main file of the saw and manually tighten the nuts.

We adjust the tension of the circuit, turning the tension screw until the connecting link touches the lower side of the guide.

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

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

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

one. Put the tire and chain on the hairpins of the chainsaws in the correct way (cutting teeth should be directed in the direction of movement). 2. Install the lid. To properly install the lid adjust the position. pins on it so that they enter the holes of the tire.

Put the screw emphasis and tighten a little until the tire and the chain do not dangle, but there was some freedom to adjust the chain stretch. four. Adjust the chain stretch with rotation of the wheel.

Put out the emphasis and tighten the lid, ensuring reliable fixation of the equipment.

It is not necessary to pull the chain to the stop, because soon it can stretch out again. The chain should have a small supply, sag slightly. It’s not difficult to check with your hand. Ideally, if it lends itself to a millimeter from the tire.

In what proportions to mix oil and gasoline for chainsaws?

The chainsaw is equipped with a single.cylinder two.stroke engine, which uses the fuel mixture to work. For refueling, you will need 92nd gasoline and special oil for two-stroke aero-cooled engines.

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

champion, understand

Mix the mixture well in a separate container. Owners Fubag FPS 56 were lucky, because it is already in the kit. At the end of the preparation of the fuel mixture, pour it into the gas tank.

What oil for chainsaws to choose? For our engines, we recommend Fubag 2T Extra semi.synthetic oil. optimally selected quality composition. We pay attention to the fact that oil for four.stroke engines or for boat engines will not work in any way.

The fuel mixture for the chainsaw is not the only thing where the oil is used. The devices have another technological tank where the lubricant is poured for the chain. By the time of fuel production, oil for the chain also ends, so it will be necessary to add it every time after refueling the tool.

Which oil to choose for lubrication of the chain? We recommend special branded Fubag Super Chain chain oil.

Test checking fuel mixture

Our saw is refuel. Launch the engine and test the oil supply.

one. Check the lids of the gas tank and the oil tank. They must be tightly closed. 2. This model has a light starting system and a primer. a fuel pump button. Stretch the handle of the air damper and turn on the ignition toggle switch.

Pull a hand starter. Important! The saw should not be in the hands, only on the ground! This is necessary in order not to get injured when jerking.

four. We give the engine to work for 30-40 seconds at idle, after which the air damper can be transferred to its original position.

I drank ready for work, click the launch levers. This model is equipped with an anti.vibration system, which significantly reduces the load on the operator. To stop the saw, just release the start button. The chain will stop, the engine needs to be held for several minutes at idle. After that, translate the ignition to the position of.

Test checking of chain oil

They figured out the engine. Now let’s evaluate the correctness of the supply of chain oil.

To do this, after starting the engine, drive the circuit at medium speed to remove excess oil. If necessary, we adjust the feed using a screwdriver. You need to insert it from the bottom of the coupling and set the desired oil consumption.

WARNING! Since the saw is a high.speed wood.cutting tool, special precautions should be taken to reduce the likelihood of accidents. The carelessness or improper use of this device can cause serious injuries. Read this instruction before use and strictly follow.

Do not use the saw that is faulty. on, improperly adjusted, collected

Keep the handles of saws with dry, clean, without oil and gasoline pollution.

Remember: This saw is intended primarily for unprofessional use. Suitable for the infrequent use of homeowners, summer residents and tourists for work such as cutting branches, workpiece and sawing firewood, etc.D. It is not intended for long.term professional use.

The rebound occurs when the moving circuit touches any object of the upper quarter of the terminal part of the guide tire or when the tree closes and pinches the saw in the puncture. The touch of the upper quarter of the end part of the guide tire to any object can make the chain plunge into the object, which for a moment will stop it. As a result, there is a sudden and fast reverse reaction that throws the saw up and back to the operator. Such saw reactions can lead to loss of control over it and serious injuries. Do not rely exclusively on the safety devices built into your saw. As a user of saws, you must take all measures to prevent the occurrence of accidents and wounds.

Hold the saw tightly and hard with both hands when working. The fingers of the left hand should

Use guide tires and chains allowed by the manufacturer.

Remember: a saw chain that reduces the rebound is a chain that reduces the bouncer and allows the cutting tool to gradually enter the wood.

Your saw is equipped with a security shortcut located on the brake handle of the backwater. This label, along with the safety rules described on these pages, should be carefully studied before starting work.

Champion 251-18: Owners reviews

Mikhalych, 65 years old, Kostroma

“I bought for a home after a thorough study of reviews on the network and consultations with sellers. He copes with all the tasks with a bang. Basil is indispensable in the household: powerful, light, economical. Great carburetor: the saw works evenly, does not stall, is gaining momentum well. I see no reason to buy an expensive branded tool when there is Champion 251-18 “.

“Bought a month ago. I saw it for three days, it cuts it normally. And then could not start. As it turned out, Magneto flew. I had to buy a new. After replacement, the chainsaw started up the first time. I think. the factory marriage was.

Advantages: low price, powerful engine and long tire.

Chain chain chapel Champion 251-18 is equipped with an engine with a volume of 50.8 cubic meter. cm. Power 3.13 l.With. (2300 W). Tire length 45 cm. The weight of the chainsaw is 5.6 kg.

Extra options

Oil quality criteria for:

  • A good degree of adhesion. You need to drop a couple of drops of oil on your fingers, squeeze them tightly and push them out. Adhesive oil will be pulled between the fingers. The remaining types of oil will simply lubricate the skin.
  • Density. The more liquid oil, the greater he has consumption. From our own experience we can say that the STIHL oil is more economically consumed and, accordingly, it is more economical. Thick oil is more slowly consumed, but it penetrates worse into areas of the chain and freeze very quickly in the cold. liquid oils penetrate the nodes better, but fly faster due to centrifugal force.
  • Environmental friendliness. To minimize the damage to the environment, it is advisable to choose a plant.based oil that can decompose after use.

How much to use?

There is a special tank for lubricating oil. Oil should be poured on the very neck. If you need to add the product, it is better to do this during the gas station refueling with fuel. During the consumption of a full fuel tank, there is usually a little butter. But if the oil does not add, it can be spent before gasoline ends and the chain will overheat.

Usually, the instructions for the saw indicate how much oil is needed for lubrication. But depending on the situation, the real amount of oil may change. For example, in frosts it is better to lubricate a chain with an oil with a low temperature of thickening, otherwise the oil pump may break. If there is no such oil, you can add a little dehydrated kerosene to the usual. The material will become more liquid, but its lubricants will decrease, so you need to work not so intensively with a saw at this time.

Before working with a saw, you need to turn it on and leave 5-10 to work idle-it takes time to get a lubricant into the chain and leaks through its nodes.

It is necessary to periodically check whether the details are lubricated, whether the oil flows to the housing. If there are problems with grease, this can be seen by the changed sound of the saw, the smell of a heating tree, an increase in the load.

How to run a chainsaw correctly

Today, chainsaws are produced by various manufacturers (known. Stihl, Husqvarna, Makita, Interskol and others, and little.known. Carver, Echo IT.P.), but the processing process for all devices will be the same. It is the performance of the following actions:

  • After starting the motor, you need to give it to work for 3 minutes (while it warms up), while performing regular extension. Leaving the chainsaw constantly working on idle is strictly contraindicated. Whoever advises you is to do, however, this approach is not true in the roots.
  • Proceed to sawing small logs (gradually increase their diameter), which is carried out at reduced values ​​of high speeds (below 600-700 revolutions per minute from the maximum value).
  • Every 5 minutes of sawing logs are made breaks. In the process of sawing, you also need to take breaks, for example, we sawed off one log, and let the tool work on xx 15-30 seconds, after which we continue further. After 5 minutes of sawing, again let the engine work on xx, after which you need to drown it out, and let the tool cool.
  • If this is a household chainsaw, then the engine needs to be drowned, and let it cool for 20-30 minutes. For professional and semi.professional units, a break is carried out in the form of a suspension of engine operation for 5 minutes.

With each subsequent tank, it is necessary to increase the duration of the engine operation. However, this applies only to professional and semi.professional units. Household chainsaws are required to run into special caution, and not allow them to overheat. It is better to start the engine more often, but let it work in short.term modes than vice versa.

How to run into a saw set

Before starting the ICE of the unit, it is recommended to lubricate the chain with oil. To do this, apply specialized chain oil to the headset, but the best option, before installing a chain on a chainsaw, it should be put in a container with butter for a couple of hours. During this time, all the links of the chain are saturated with lubrication, which will ensure a decrease in the friction coefficient, and an increase in the resource.

Set the chain on the chainsaw, and ensure its tension so that it rotates freely when exposed to the hand. The correct stretch of the circuit is checked by lifting it in the upper part of the tire. In this case, the shank of one link should be completely visible. During the riskpiece run, you need to regularly check the tension of the circuit, and carry out a lifting.

Preparation of fuel mixture for a chainsaw

Gasoline should be with an octane number no less than AI92. You can also fill in AI95, but its quality at our gas station leaves much to be desired, so if you are not sure of the 95th, it is better to take gasoline AI92 gasoline to dilute gasoline into a chainsaw. You should not take gasoline in the same way for a long time in the canister, tank or any other capacity. Gasoline for the preparation of the fuel mixture in the chainsaw should be fresh, otherwise it loses its properties, in particular the octane number, and even if you run the chainsaw on such fuel, it will not give out full power. And the saddest thing in this case is that the failure of the chainsaw due to poor.quality fuel is considered a non.warranty occasion and leads to expensive repairs. Sometimes it’s easier to buy a new chainsaw than to repair it after such a breakdown!

Read more about gasoline for chainsaws here:


Oil for 2-stroke engines according to the American Petroleum Institute (API) classification, the American Oil Institute has an API-TB class, there are also API-TC oil oils, but they are designed to work with less loads than most of the chainsups we common. If we take the classification class of Japan Automobile Standards Organization (JASO) Japanese standardization organization in the field of automotive industry, then focus on JASO-FB and JASO FD classes (see.Table 1 below.).Not in any case do not use oil for four.stroke engines! Remember that in a two.stroke engine the oil should be completely burned, which means it is better to take synthetic oil, since it gives less smoke and burning residues. And if you pour oil for four.stroke engines in your chainsaw, which will not burn completely and as a result of the fog, then you will fail. The best thing to be guided by when choosing oil for a chainsaw is an instruction for her.

When preparing a fuel mixture of gasoline and oil for a chainsaw, be sure to see the manufacturer’s recommendations. Why is it so important to observe these recommended proportions? With a small amount of oil in gasoline, the cylinder and the piston will occur and the bulletin will occur, and this is the exit of the CPG and repair. If there is a lot of oils in gasoline, then this is a dozen and the failure again.Each manufacturer has its own recommendations on proportions (see.Table 2 below). Try not to store the finished mixture longer than a month. Do not store it under direct sunlight and openly. Avoid water and dust, this will lead to the failure of the carburetor, since the fuel filter is often not able to completely clean the fuel.

Since they often come from search engines at the request of the same “how much oil is pouring 1.2.5 liters of gasoline”, then I add another table under which you can find out how much oil to gasoline according to the accepted proportions. The proportions can be viewed in table 2 or, more precisely in the instructions for your chainsaw.

Selecting two.stroke oil for a chainsaw

Having decided on the question of how to breed gasoline with butter into a chainsaw, it is worth finding out which type of lubricant is better to use. First you need to understand that mixing fuel is required exclusively with two.stroke oils, but not motorized for automobile engines, and even more so, working out.

Special oils are called. two.stroke. By color, they are not only red, but green and blue. Red color indicates that it is mineral (cheapest). Blue and green. semi.synthetics. Semi.synthetics are naturally better, but when it comes to one.time use (t.e., When the lubricant burns with gasoline, then mineral oil is the best option in terms of cost and reliability). The color of the oil also indicates the use of the appropriate additives, but the most important thing is to choose a lubricant, well.known manufacturers need. By color, you can determine that fuel is mixed with grease.

Today it is very easy to buy a fake or lubrication of low quality, so you should not save. The following manufacturers are recommended to choose two.stroke oils:

If when buying expensive oils, they tell you that you are overpaying for the brand, then this is so. Only you pay for the guarantee that the purchased substance is high.quality, and has only a positive effect on the engine engine. No need to look for options cheaper, because saving on fuel and lubricants, you reduce the life of the engine and the entire tool in general.

Interesting to know! Two.stroke oil has a different consistency and the number of additives. Motor oil is intended for constant lubrication of mechanisms, and two.stroke lubricates the parts when contacting it, and when it enters with gasoline into the cylinder, burns out.

Summing up, it should be noted that the chainsaws are necessary to refuel a gas-oil mixture in a ratio of 1 liter of fuel add 20 ml of oil. If you use a proportion using 25 ml of lubricants, then nothing terrible with the ICE will happen. instructions for refueling

Wanting to season the chainsaw, you need to follow the simple algorithm:

  • Prepare fuel in the recommended proportion of gasoline and oil for two.stroke chainsaws.
  • Prepare the saw for refueling, cleaning its surface from sawdust and chips.
  • Put the saw on a flat stable stand with a tank with a tank up.
  • Gently place a small funnel (plastic or metal, resistant to combustible materials, easily purchased in the auto.goods store in the auto.goods store)
  • Carefully pour fuel into the tank, avoiding overflow. It is unacceptable to pour under the lid. this will lead to splashing out during screwing the cover!
  • Close fuel tank lid
  • Replace the lubricant for the chain (mandatory!)
  • Start the motor at idle.

After prolonged downtime, you need to drain the rest of the fuel mixture from the saw. You can’t use it. since gasoline quickly loses its properties in such a mixture. The consequence will be unstable work and risk of breakdown.

What will happen if you fill in the surgery in the chainsaw

When the owner of the chainsaw for some time will use it, he may want to conduct some modification of the tool. And it’s good if his desires are limited to the purchase of various nozzles that expand the functionality of the chainsaw. But some go further. they begin to experiment with gasoline and butter on which their saw works.

If we have already talked about gasoline earlier (most modern saws require it with a high octane number-not lower than 92-95), then it is worth saying about the oil. Many motorists have a significant amount of machine oil used during the operation of the car. And therefore, some have a desire to use this material to refuel a chainsaw.

If this is done, then the engine will fail. The reason for this will be, first of all, the low lubricant of the re.used oil. It will burn with a large release of black soot. The metal particles contained in the oil will first score the fuel filter (these are those particles that are larger), and then. the sealing rings of the cylinder will fail. The metal suspension in the oil will damage the surface of the cylinders themselves and bearings.

Some “rationalizers” try to use working out to lubricate the chain itself and the pads on which it is located. This will not lead to anything good. What exactly will happen. you can see in the attached video.
