Reasons why the chainsaw won't start

The launch of the tool must be carried out strictly according to the instructions. But if you have completed all of the above points, and the saw has not started, it means that something is wrong with it. There are several reasons why it may not start:

• there is no spark;
• no fuel is supplied;
• air filter clogged.

So what do you need to do to identify the true reason why the tool is not working?

Firstly, it must be said that if the tool does not start, the screws on the carburetor should never be turned. And if you are not a professional in this field, then do not even try to tune anything with your own hands or try to wind up the instrument.

The steps listed below, necessary for the tool to start working, must be performed in the strictly specified sequence. You need to start performing the next item only when the previous one did not work. The actions are as follows:

• At first, you can try to simply do nothing with the instrument for at least 5-10 minutes. There is a possibility that during the start-up, his candle was flooded, which sometimes occurs. Wait, then try again to follow the instructions;
• Try to remove the cover of the tool body, then remove the air filter from there, try to start the saw without it. If the filter becomes dirty, wash it in soapy water, then dry it or replace it with another one;
• Unscrew the spark plug and check for a spark. If it is absent, then you can try to put another one. If the spark does not appear in the end, then this indicates that the ignition unit is damaged, and the tool needs to be repaired. If there is still a spark, but it still did not work to start the chainsaw, proceed to the following steps;
• In the event that a spark is present, and the candle is wet, then the chainsaw must be turned over. Thanks to this, excess gas will pour out of the cylinder, if it was there. It is necessary to pull the starter without a candle about 10-15 times, this will allow the combustion chamber to be ventilated. Ignite the candle and then screw it back. If there is a possibility, then change it to another, try to start the instrument again;
• If the candle is dry, then you need to take a syringe and draw one or two cubes of gasoline mixture into it, then pour it into the cylinder. Try to power the instrument again. There is a chance that a small speck has entered the carburetor and is preventing the fuel from entering the combustion chamber. Such a speck can be pulled out using the flow that is formed after starting the car by adding fuel directly to the cylinder itself;
• We unscrew and remove the muffler. However, be careful not to damage the gasket between the engine and muffler. Once again we try to start the chainsaw without the air filter and muffler. When he is not there, you can study the piston from the inside. If there are scuffs or burrs on the piston or on the cylinder walls, or the piston ring is clamped by burrs, this indicates that the piston ring is worn out or broken. This often happens if a little oil mixture is poured into the fuel. In this case, the only way out is to give the tool to a service center or buy a new one, since replacing the piston will be much more expensive.

In the above material, it was considered how to properly start the chainsaw using one of the Calm models as an example, as well as how to behave if the tool cannot start. If you are new to this business or have encountered a problem, then such information may be useful to you in the future.

Starting without starter

Often, many home craftsmen are interested in whether it is possible to operate a chainsaw without the help of a starter. The answer is very simple: in principle, this cannot be done.

None of the manufacturers provided any other alternative launch methods. Therefore, even if you remove the starter and try to start the car in some other way, it will still not work, since there will be violations in the cooling system. In this system, there is a volute to transfer the flow of cold air from the flywheel impeller to the side of the cylinder. If it is not there, the engine will overheat and eventually jam.

Chainsaw service

Always check the amount of fuel before using the saw.

The degree of filling of the oil tank should be checked periodically, it is very important to prevent a decrease in the oil level. Before sawing, test the degree of chain tension, sharpening sharpness

The tire bearings are lubricated monthly.

At the end of the work, the saw is cleaned of sawdust and shavings. The air filter is washed - the best option is a nylon or foam filter, as opposed to a felt disposable one. Cleaning the air filter will be required when there are interruptions in work, engine choking during sawing.

Wipe cooling fins, ventilation holes. Remember to clean the brake band. It is advisable to use the prepared fuel mixture within 3-4 weeks. It should be remembered that careful maintenance of the chainsaw largely affects the duration of the tool, the efficiency of work, the absence of breakdowns and malfunctions.

For even wear of the tire, it is necessary to periodically turn it over with its reverse side. Experienced chainsaw owners, in the recommendations on how to use a chainsaw, advise having three chains, which ensures uniform wear of the drive gear. You cannot cut with a blunt chain, it is dangerous, the load on the engine increases, the saw, as a result, cuts completely poorly - crooked or goes to one side. If you intend to stop using the saw for a long time, release the chain tension.

Chain saw design and working principle

The construction of the chain saw is quite simple. A chain saw consists of a motor, a bar (chain guide) and a chain. The chain has special teeth, thanks to which the cut is carried out.

Fig. 1. Chain saw device. All designated elements are characteristic of both electric and gasoline saws. The only difference is the engine used.

In their design, chain saws have three important elements: the chain saw tensioner, the chain lubrication system and the chain brake.

During operation, the chain heats up and stretches, which negatively affects the performance and safety of the chain saw. The chain saw tensioner is designed to compensate for chain stretch.

The chain lubrication system consists of an oil tank and an oil channel through which lubrication is supplied. Chain lubrication protects the chain from dry friction against the bar and overheating of the cutting tool, which increases the life of the chain and bar.

The chain brake is a safety device to ensure the safety of your chain saw. When hitting an obstacle, such as the ground, the chain saw tends to bounce upward. If at this moment it breaks out of the hands, then the brake will stop the chain and protect against possible injury.

User manual

Reciprocating saw Interskol is suitable for working with materials of different density, wood, metal, building blocks, etc. It is recommended to work with the device at temperatures from -10 to +40 degrees. It is not recommended to carry out work if there is direct rainfall on the machine. The saw operates on continuous power from the mains.

Recommendations before starting work:

• inspect the saw and its completeness;
• after transportation in the winter season, it is recommended to leave it in a warm room until the condensate is completely dry;
• check the fixation of all fasteners;
• start the saw at idle speed.

Reciprocating saw device

Recommendations for sawing materials:

• work must be carried out smoothly, without unnecessary pressing on the tool;
• it is recommended to promptly clean the work surface from sawdust and debris;
• it is forbidden to obstruct the ventilation openings, this may lead to overheating;
• when working with metal, it is advisable to periodically lubricate the cutting area with machine oil;
• cutting is recommended to be carried out evenly, without deviations in different directions.

Maintenance

To prevent sheet corrosion and equipment failure, it is recommended to carry out periodic maintenance. Heavy contamination of the Interskol reciprocating saw can lead to serious malfunctions. After working with the saw, it is worth cleaning the attachment point of the saw blade. To do this, it is enough to lightly tap the device on a flat surface or clean it with a thin long object. During prolonged work with highly dusty materials, the device must be periodically blown out from the inside.

Installing a hacksaw blade

Interskol saw maintenance includes:

• Before working on the product, it is recommended to inspect it for any faults. If necessary, replace defective parts;
• after finishing the sawing work, do not touch the saw part, as this can lead to burns;
• after installing the saw blade, make sure that it is well secured;
• the saw blade is recommended to be installed based on the characteristics of work and material
• during work, you should adhere to the safety rules.

When and how to fill

Where to fill the chain oil is clear. There is a separate container for this. In most chainsaws, the size of this container is calculated taking into account the volume of the saw's gas tank. When both tanks are full, they empty at about the same time. Therefore, it is recommended to fill the full volume of the oil tank at the same time as filling the fuel tank. Then you don't have to be distracted by topping up twice.

Before starting work, it is useful to check if oil will flow to the chain. To do this, it is enough to direct the end of the tire onto a flat surface. Some of the grease will fly off the edge of the tire. If droplets enter the surface, the system is operating normally.

At high negative temperatures, summer oil thickens and its lubricity deteriorates. Therefore, it is worth using brands designed for winter conditions. If this is not possible, then it is worth taking the time to dilute the existing oil to reduce its thickness. It is best to dilute with kerosene in a ratio of 1 to 4.

Some models have an adjustable feed rate in the lubrication system. It is useful for correcting in the event of a change in lubricant type.

If the oil from one manufacturer has run out, and the same type is available, but from a different company, then their mixing is allowed, provided that they are used immediately. Leaving such a mixture for a long time is not worth it.

2> Brand history

The Shtil company was founded 90 years ago by the German engineer Andreas Shtil in the 1920s. At that time, Stihl worked in the German city of Stuttgart - he created a design bureau, whose direct field of activity included work with wood. Then trees were felled with axes and such work took away a lot of labor from the workers.

STIHL products

In 1929, Andreas Stihl invented and officially introduced the world to the first portable chain saw.It is Stihl's idea that "the saw goes to the tree" that allows modern lumberjacks to work with small, portable electric saws and gasoline saws, avoiding the constant use of bulky sawmills. The first saw weighed 46 kg, while modern semi-professional and professional chainsaws weigh from 5 to 9 kg.

The first STIHL saw

In the early 50s, chainsaws appeared smaller than the flagship model, for example, the Stihl chainsaw, whose power was 6 hp, and the weight was 12 kg. In 2016 STIHL celebrated its 90th anniversary. With the legendary powerful and modern STIHL "CONTRA" model, German developers have increased the productivity of forestry operations by 200%.

Nowadays, STIHL has become a synonym for high-quality technology, both electric and gasoline resource. The range of the company includes the following types of devices:

• chainsaws;
• electric saws;
• garden trimmers;
• brush cutters;
• drills and other battery technology;
• motor-drills;
• manual garden and country tools;
• protective gear and equipment for workers and gardening.

Fuel mixture preparation rules

If you wish, you can create the mixture in question with your own hands. It is recommended to do this before using the chainsaw directly. Storing a ready-made substance for more than 10 days leads to the formation of a chemical bond between the additives, which reduces the engine's service life. Experts recommend that before putting the chainsaw for long-term storage, drain the fuel and work out the residues at idle.

The proportions should be selected in accordance with the recommendations of the manufacturer of the device itself. Depending on the model and its technical characteristics, the indicator can vary from 1:20 to 1: 100 or more.

Chainsaw fuel mixture

It is strictly forbidden to use waste or oil that is not intended for the operation of a two-stroke motor when mixing active elements.

How is mixing done

You also need to pay quite a lot of attention to the direct mixing process of the components used. As a rule, the fuel mixture is prepared in a volume that will be sufficient for 3-4 refueling of the used device. The mixing procedure can only be carried out using volumetric dishes.

Among the features of the issue under consideration, the following points should be noted:

1. Some chainsaw manufacturers include volumetric containers with fuel and oil markings.
2. In the absence of a special container, you can use a canister or dry bottle. The dosage is convenient to carry out using a conventional syringe without a needle.

After adding all the ingredients to one container, you can proceed to direct mixing of the components. For this, the container is closed with a lid, after which it is shaken to obtain a homogeneous substance.

Working proportions of the fuel mixture

As previously noted, the proportions of the ratio of oil and gasoline for a chainsaw can differ significantly, largely depending on the features of the design itself. An example of mixing is the ratio of 40: 1 and 50: 1. This ratio provides high-quality lubrication of the internal elements of the installed engine.

In some cases, the concentration of the lubricant can be adjusted upwards to provide more efficient lubrication. An example would be when a new tool is being machined. In addition, it is also possible to increase the cooling efficiency of the structure by adding a large amount of oil to the mixture. Experts recommend increasing the oil concentration by no more than 20% of the usual value.

As practice shows, in most cases the sawman himself has to adjust the concentration of oil in the fuel, depending on the characteristics of the work being done. This is due to the fact that as the structure wears out, serious breakdowns can occur. With normal performance, sawing can be done for extended periods.

Measuring containers

As a measuring container, various containers with applied markings can be used. Ratio control is simplified by using a proprietary container that is included in the package.

It should be borne in mind that volumetric dishes are included in the factory kit, even for budget models. However, an ordinary syringe of increased capacity also performs well.

Storage advice

It is not recommended to save time and mix the composition directly in the chainsaw tank. This is due to the fact that it will be rather difficult to achieve the required result. Storage guidelines are as follows:

1. You can store the resulting mixture for no more than 2 weeks. With an increase in the ambient temperature, the shelf life is reduced to 10 days.
2. In some cases, in order to save money, a previously prepared and expired mixture is added to a new one. However, its concentration should be no more than 10%.

Storing homemade mixture

To prolong the operation of the fuel system, it is recommended to filter the composition through the material represented by fibers.

Proportions of oil and gasoline

The exact ratio of oil to fuel is indicated in the instructions for the chainsaw or on its packaging. It is equally bad not to top up or pour oil. If you use a material and a saw from the same company, you will need to add 50 parts of gasoline to one part of the oil. If the brands are different, it is better to reduce the amount of gasoline to 40 parts.

Do not follow the advice from the Internet, but the information specified in the instructions for the chainsaw. Different manufacturers recommend different proportions of materials, the ratio can be 1:30 or even 1: 100.

The correct ratio of gasoline to oil is critical. To measure the correct volume, you can focus on the dispenser on the oil package or use a medical syringe.

You can also find special mixing containers on sale that will help you measure the volume of both products.

It is better to cook the mixture in the amount necessary at one time. According to the recommendations of technologists, the mixture cannot be stored in a mixed form for more than three days. During long-term storage, resinous deposits form in the mixture, and the flammable properties deteriorate.

The AI-92 fuel is most suitable for this mixture. In AI-95, various additives are often added; many fakes can be found.

Expert opinion
Kulikov Vladimir Sergeevich

Dilute fuel and oil in a container made of metal or dense plastic that does not react with petroleum products. Food grade plastic should not be used, as gasoline will decompose and change the properties of the fuel mixture.

Understanding the types

The most important parameter is the base from which the lubricant is made.

When choosing a lubricant, you need to pay attention to the following parameters:

• Base (synthetics, mineral, semi-synthetics).
• Environmental friendliness.
• Exhaust toxicity.
• Detergent properties.
• Wear.
• Burning rings.
• The degree of smoke generation.

Unless you plan on using the saw frequently and heavily, it doesn't really matter which base to use the oil on. The equipment is so high-quality that it is more likely to break down in decades due to general wear of parts than from using the wrong oil.

By the way, if active use of the saw is expected, it is important that the shaft rotates at a constant frequency. The service life of the tool directly depends on the stability of the shaft - the less the frequency changes, the longer the technique will work

What chainsaw oil do you use?

Synthetic Mineral

And synthetic-based lubricants are designed specifically for equipment that works on an industrial scale.

If you have been using mineral water for a long time, you cannot switch to synthetics. If the equipment works on mineral water for more than 100 hours, a large layer of carbon deposits will have time to form in the crankcase. Synthetic oil will break down carbon deposits and loose fragments can damage the saw cylinder.

Since a person is forced to work next to a chainsaw, it must produce a minimum of harmful substances. The lower the smoke production of the oil, the better for you.
