How to attach the chain to the chain saw
How to chain a chainsaw correctly?
To choose the best cutting headset for a particular power saw, the gardener needs to examine a few important parameters and criteria for the chain:
- the length. must necessarily match the length of the metal guide bar that is installed. Some novice users try to install shortened cutting bodies on the bars of their tools, believing that over time they will still stretch and fit tightly on the bar. This is a big mistake, because the length of the guide bar and the new headset must be the same. If, however, the chain sags as a result of use, it is easy to shorten it by removing a few links;
- Factory sharpening angle. parts sharpened at an angle of 30⁰ are easier to handle. For regular work with frozen and damp wood, the 10⁰ angle headsets are the most effective;
- the manufacturer. in order for the cutting organ to fit perfectly on the bar, it is necessary to choose the products of the brand of the manufacturer of the installed guide rail and the electric saw itself. For example, Makita electric saws and guide bars should be fitted with chains from the same manufacturer.
To choose a chain for the electric saw, the owner of the equipment should take into account the purposes for which the cutting set will be used. For the ability to saw relatively large wood, chains with a pitch of 3/8″ are suitable. If you have a low load, a blade pitch of 0.325″ is the better choice for your power tool.
Why does the chain come off the chain on a chainsaw or electric saw??
Owners of chain saws are occasionally faced with a common problem. the chain starts to come off the chainsaw or electric saw. Why this is the case, we discuss later in this overview. There are only three main reasons why the chain comes off:
Let’s look at why this or that problem occurs:
If the chain stretches, starts to sag, slips off the tire
The reason is most likely wear and tear of the component. The chain has a finite life and is the most rapidly wearing working part of a chainsaw or electric saw. The metal deforms due to stress, so not only does it become blunt, but it also becomes about 1 cm. longer than on the new tool. The easiest way is to change the component, which means buying and installing a new chain.
For information on how to tighten the chain and if it is possible to tighten the chain at home, in the review.
If there are problems with the bar, they lie in the place where it is attached.
This reason is quite common: in the groove located between the outer plate mounted on the chainring and the inner plate located on the body of the gasoline or electric saw. The shroud is usually bolted in place. This mount is called the engine assembly. The tire mount, like the drive sprocket, is covered with protective covers. When the fastener bolts loosen, the degree of vibration of the bar increases, it begins to move.
If there is nothing wrong with the bar, the tension is fine, and so is the work of the tool. If it is a loose guide bar that is causing the chain to stretch, reattach the guide bar and see how the chain saw works.
Trouble with the sprocket.
If the drive sprocket is not properly secured, the chainsaw chain will also need tensioning because slack is unavoidable. Attach the tire sprocket by removing the engine guard, spark plugs, and pulling out the air filter. A stopper is installed in place of the spark plug, the main task of which is to fix the piston. Then you can use a special wrench or a universal wrench for angle grinder to spin the clutch disk in a clockwise direction.
Make sure that the piston is in the extreme position. if you look in the hole for screwing in the candle, the piston should be at the bottom.
Once the piston is secured, you can proceed to clamp the drive sprocket. Then all the elements are assembled in reverse order.
Features of selecting a tire for the electric saw
When buying a tire, the first thing to look for is the material it is made of. If it is strong enough and reliable enough, the part will serve for a long time and in good working order. In addition to the material, when choosing a tire, you need to study its parameters:
- The shank. with this you can determine if the guide bar fits on your model of electric saw. It’s all about the location of the electric saw tensioner and the oil hole in the chain. Most well-known brands produce brand-name shanks for their electric saw models. At the same time, shanks from different companies can replace each other;
- Groove width. in today’s market, you can choose bars with a groove width of 1.1 and 1.3 mm for domestic electric saws of low power, and 1.5 and 1.6 mm for more powerful models of electric saws;
- Power saw bar length. this parameter is one of the most important when choosing a part. To determine the length of a chainsaw bar, you must measure the distance between the outermost point of the bar nose and the sprocket stop. Most often it is 12 to 20 inches. it all depends on the model of electric saw. The longer the bar you choose, the larger the tree you can cut.
A properly selected and compatible guide bar, chain, and electric saw will allow you to work efficiently and with peace of mind without spending too much money or time.

Understand how to install the chain of an electric saw, you can, after carefully researching its purpose, structure, features of equipment, checking the degree of tension of the track. It should be noted that this equipment is distinguished by the indescribable ease of use. That’s why all work is carried out quickly, smoothly and consistently.
Electric chainsaws are used in construction and home workshops to perform various tasks.
Purpose of chainsaw chain
In the near future, cutting tools are presented in abundance. To make it more convenient, it’s better to get high quality pieces.
Electric saws are used in the construction industry for cutting wooden surfaces, construction and landscaping. This is a practical device, whose universal properties allow it to work from a two-phase motor. The sharp elements of this device are represented by chains of various configurations. The main part of such devices have iron bars and chain wheels.
Main parts of chainsaws.
Non-professional power saws are designed for a chain pitch of 3.25 inches. These dimensions significantly reduce the coefficient of vibration movements, but this does not have the best effect on the power of the device: it drops markedly. High-quality mechanisms are equipped with rows that move in steps of 3/8 and 0.404 inches. When buying a chainsaw, you should pay special attention to the quality of the sharp part, i.e. е. tracks.
Features of the chainsaw cutting part
When buying an electric saw, it is important to pay attention to the following components:
The circular saw is one kind of tool.
Quality samples of such tools are characterized by the highest performance indicators. Such models are constant, do not change their data as a result of constant friction, and can work in all adverse conditions. All chainsaws have 50 main links. Their step distance corresponds to 3/8, the groove. 1.3 mm. In some cases, the choice of this element depends on certain features:
- The clear adherence to the instructions of the electric saw;
- information about the quality of the chain;
- familiarity with the pitch size of several links.

Devices with 52 links have a distance gap of 38 at a groove of 1.3 mm and a bar of 36 cm. Power saws used in the toughest conditions are equipped with tracks made of special alloys.
Installing the chain: peculiarities
To keep your chainsaw working properly, you need to make sure that all its devices are working properly. The track, installed according to all the rules, will save you from possible injuries. Work on the installation is carried out with the use of devices:
Particular attention must be paid to the degree to which the chain is sharpened and tensioned. Check the working condition of the track at regular intervals:
- To begin with, you should examine the saw bars, which are fixed with a cover on the clutch.
- If the chain needs to be renewed, the nuts are loosened with a wrench. It is not allowed to remove the chain brake tension at the same time.
- The brake pad is moved to the side. The grooves that allow for the tensioning of the chain part deserve special attention.
- On the left side move the saw bars, trying to touch the main sprocket. One of the chain elements is fixed to the driving part, the shank is fixed in the bar holes.
- Adjusting the screw allows for proper tensioning of this part. As the cover is installed, start screwing on the nuts.
- The saw bar is put up and the nuts are tightened all the way.
- The distance of the track on the tire is checked.

Install the chain by checking the tension after each installation or replacement. Insufficient securing of the part can cause it to jump off the base of the guide bar and injure the worker.
How to sharpen an electric saw chain with your own hands?
Many craftsmen sharpen the chain of an electric saw at the first symptoms of wear on its cutting teeth. However, you will not be able to use any particular tool for this procedure. You need a whole set of special tools for the job. To do this, you will need:
- A flat file is needed to correct the depth stop;
- A round file that has reference lines;
- Sharpening mandrel. this will help determine the angle.
To sharpen the chain of an electric chainsaw, the saw blade must be left on the bar. The guide bar must be securely clamped in a vise. The diameter of the file you use should always match the diameter of the chain teeth.
When using a round file, make sure it does not protrude more than 1/5 of its length over the chain teeth. The first chain tooth to be sharpened should be marked with a marker so as not to go a second round.
The chain of your electric saw should be sharpened with precise, rhythmic motions and only in one direction. After you have filed a few times, go on to refine the stop as it wears out over time and loses its shape. When working, place the caliber with its end face on the edge of the limiter. If the limiter is too far out of caliber, it must be sharpened with a flat file. The saw blade should be perfectly perpendicular to the guide bar.
You can’t visually check if the chain is properly sharpened. You can only find out if you have done it right when you are sawing the wood.
How to attach the chain to the chain saw. a detailed algorithm
After you have chosen a sawmill element for your tool, you must wonder how to mount the chain on your electric chainsaw with your own hands. In fact, there is nothing complicated about this procedure. All you need to do is to study carefully the indicated algorithm and work accordingly.
To install the chain on the electric saw, you need to act in this order:
- To begin with, you will need to pull back the protective shield, while lowering the brake lever;
- Then use a screwdriver to turn the tensioner and unscrew the nut. This way you will loosen the tension of the old chain;
- Remove the cover and separate the bar with the chain from the sprocket;
- Then remove the old chain and replace it with the new saw element;
- Then put the bar on the sprocket and adjust the tension of the chain with the screw. Try to tension the new chain without jerking the chain.
Some modern electric saws are equipped with special wing nuts for quick tensioning of the chain. To install a new chain on such a power saw, you need to:
- Lower the brake lever and unscrew the nut;
- Remove the cover and push the bar back a little;
- Remove the old chain and install the new saw element. A new chain is mounted first on the dismantled sprocket and then along the entire length of the bar;
- The chain sprocket should be reinstalled and the nut should be tightened.
The chain tensioning wheel should end up turning in the direction of the arrow on the housing and tighten the thumbscrews all the way.
How to install the chain correctly on the electric chain saw
When carrying out an impressive amount of carpentry work, a reliable electric saw is needed, regardless of where the wood is cut: in the house or outdoors. The quality and functionality of the tool depends on the condition of the chain and guide bar. To attach the chain correctly to the chainsaw is the major challenge for the user and makes later use of the chainsaw much easier. Practical hints can help you do it even if you have never done it before.
How to handle the saw properly? (Unhelpful tips)
After long storage, especially in unheated rooms, condensation may form in the saw, causing a short circuit during start-up. To avoid this, keep the saw in a warm, dry place for a day or two before use.
READ What type of handsaw to choose for your home?
For making firewood it is advisable to use gasoline models, because they have a huge power and speed (8 nine thousand rpm) than electronic models (about 5 thousand rpm). electronic chainsaws can not be used continuously for a long time.
Is not equipped with a thermal motor control, the insulation of the armature winding can melt and cause a short circuit. If the system is installed, it will shut off the motor cool-down tool almost every minute.
Electric models are recommended for use in carpentry or small, cosmetic gardening and DIY jobs.
To cool down, put the tool down more often. By the way, most home electric saw capable of uninterrupted operation for a couple of minutes.
Electronic models require careful monitoring of voltage stability, especially with low-powered saws. In our electronic networks (especially in rural areas) are occasional power surges, and the value of such surges on weekends and holidays can reach 15-20%. By the way, the stronger is the motor, the less sensitive is the device to voltage stability.
Always pay attention to the saw blade or chain when working with an electric saw. If the saw becomes very hot during cutting, it is a sign of badly sharpened teeth.
To be able to cut the trimmer line with the electric circular saw, the edges of the blade cover must rest on the tree surface and be against it during sawing. If it is problematic to move the saw blade over the bulky wood, it is necessary at first, without stopping the work, to push it back a few cm along the kerf, and then again slowly guide the saw movement along the same mowing strip.
Not only the machine itself but also its accessories need care. For example, the chain should be re-edited and sharpened after each working day. Not only that, if the tool is not equipped with automatic chain lubrication (there are only a few of them, though), you should frequently dip the bar into a bucket with oil.
Correctly sharpened and adjusted saw cut itself, additional efforts to it actually is not required. After use remove saw blade or chain, wipe off sawdust, clean it with kerosene and put it in a special box until it can be used again.
Tool storage. This is a topic for a separate discussion. Particular attention should be paid to saving battery models, which should be stored in a dry and warm place at an ambient temperature not exceeding 50 degrees Celsius, otherwise the battery may fail.
Nickel cadmium battery life is maximized when used in the temperature range from 10 degrees Celsius to 35-40 degrees Celsius. Naturally, it is forbidden to leave the tool in direct sunlight, much less in the rain.
Not only are sawing tools unsafe, but they are also very unsafe, that’s why constant and particular attention should be paid to the questions of safety. When working with an electric circular saw, you must first check the serviceability of fixtures and wiring, the electric saw itself should be grounded.
For example, boards should only be cut in dry conditions. Never work near an open source of water, in a humid or wet environment.
The circular saw blade must be firmly secured and checked before use. Talking about circular saws it is worth to underline: every model is designed for the usage of the blade with the certain diameter.
A larger blade cannot be fitted in principle and a smaller blade is not acceptable for safety reasons: in this case there is a small gap between the blade and the guard where your finger can get caught. And because the speed of the disc is very high, the guarantee of missing a finger is almost one hundred percent.
How to fit the chain to your electric saw
When doing a large amount of carpentry work, a reliable electric saw is essential no matter where the wood is cut: in the house or outdoors. Quality and serviceability of the tool directly depends on the condition of its main elements: chain and bar. Getting the chain right on the electric saw is the main task facing the user, greatly facilitating subsequent operation. Practical hints can help you do it even if you’ve never done it before.
How an electric chainsaw works
Turning speed is often not specified. It is clear that there is a collector motor inside, but how fast is it? Let’s pay attention to the rotation speed parameter of the chain. It is expressed in meters per second (13.5) and indicates how fast the links are moving. We know that the length of the tire is 14 inches (35.5 centimeters). For reference: The bar of an electric saw is a metal frame with a chain running along it.
The cumulative length of the links is about 85 centimeters. Take a reserve for the tensioning mechanism and the transverse dimension. This means that per second the total number of revolutions is N = 13.5 / 0.85 = 16. That’s about 950 per minute. This is not the frequency of the motor, but the number of revolutions of the chain. But there is information on the drive sprocket, it says: 6T x 9.53. This means that there are 6 teeth, and the distance between the teeth is 3/8 inch (9.53 millimeters). It remains to multiply these two figures to get the circumference length: 6 x 9,53 = 60 millimeters (rounded).
It turns out that the drive sprocket makes a circle of 85/6 = 15 revolutions, which gives a shaft speed of about 14000 rpm. Provided that there is no gearbox inside. There is a high-speed collector motor inside (you can’t make an asynchronous motor reach this speed), so there is no choice. Sometimes a gearbox is used, in other cases the drive is direct. In the second case, the electric chainsaw weighs less and has fewer parts that can break.
The motor lies in a transverse plane to the movement of the chain, for obvious reasons. The sprocket on the shaft extends outward and the chain is put on. It is tightened around the bar, and then attached to the body. This is where the important mechanisms are located:
To this end, long slots are made on the plane of the steel under the spikes of the housing. Next, the attachment systems begin to differ. The electric saw manufacturers solve the problem in their own way. For example, the tension is ensured by a symmetrical spiral screw, like Champion, or by a single spike, like Makita.
This is tightened usually with a wrench. But Makita has a special folding screw. It is good that it is part of the design, but users complain that the elasticity of the springs is reduced and the head starts to wobble. Pay attention to what is said if you think it is important. It is good, if the cord has a rubber nest for the mentioned key.
But there is also an adjustment mechanism on duty. The chain slackens during work and it would be inconvenient to remove the cover by unscrewing the screw all the time. The standby mechanism is designed in different ways. For example, in the Champion it needs to be tightened with a screwdriver and the socket is located on the side of the blade.
The Sparky has no screw, but there is a large diameter plastic thumbwheel. It is conveniently located on the side. In standby mode, it does not take long to tighten the chain. The wheel may look brittle, and there is a fear that the mechanism is prone to breakage. When selecting a chain saw, watch out for standby devices to maintain chain tension.
This lowers the friction coefficient and reduces heat build-up. Users complain that Makita pumps fail easily, and the oil either stops flowing or injects too quickly. There is a sight glass on the side of the electric saw to check the level. You can find the oil type in the instruction manual. If you see smoke from the guide bar when you are sawing off a log, stop sawing immediately.
The power saw usually has two handles. The first one is at the front left of the housing. Arc-shaped and robust. In this place there is a shield that serves both as protection against flying chips and as an emergency stop switch. In many cases a kickback occurs when using an electric chain saw: the bar with the moving chain bounces back toward the lumberjack. This causes the guide rail to hit your hands and flip the switch that cuts the power to the motor. The electric saw stops immediately, blocking the possibility of an accident.
In this sense, all units are designed the same, but some have an additional chain guard. In practice, an electric saw refuses to cut thick, wet logs. In the event of a fatal blockage, the motor is saved from certain death. The chance of the chain getting stuck on the tire is minimal, but it is present. If it jams, the gearbox may fail. Do not use this type of product without taking extra precautions.
The back handle is designed for right handed use. When you pick up the chainsaw, make sure it is well-balanced. Modern 2 kW models weigh a little over 2 kg, which makes it easy to work. The electric chainsaw must rest loosely in your hands for comfortable cutting. Maximum log diameters are given in the technical data. Size is limited by the length of the bar.
You can not touch objects with the end of the working electric saw, in this case the chain bounces in an arc towards the head of the master. This can be disastrous. Similarly, you should not try to saw logs whose diameter exceeds the diameter specified in the instructions.
When the saw chain is off, it is hidden in a cover that can be removed when the saw is in operation. The front body of the power saw is equipped with plastic or steel teeth. They need to rest on the workpiece and then swing the blade up and down. It’s easier to cut that way, and the teeth serve as a stopper on that side. The last thing we want to say relates to power:
