How to put the chain on a chainsaw correctly

Chain thickness classification

The groove on the saw bar on different units has its own thickness, so for greater efficiency it is better to choose the optimal one. The minimum parameter is 1.1 mm. Such a part can only be installed on household mechanisms with low power. Chain with a link width of 1.3 mm is more popular. Applies to both cheap and semi-professional Goodluck chainsaws.

The rest of the types are used on powerful tools: 1.5, 1.6 and 2 mm. The last 2 of the listed ones are only for professional Ural mechanisms. But before choosing a part by thickness, you need to find out which of them can be installed on the saw bar of a particular tool.

How to lubricate the chain?

  • 1.1. the simplest saws;
  • 1.3 and 1.5 are semi-professional;
  • 1.6 and 2 mm. the most powerful.

Proper maintenance of the chain and correct tensioning is the key to durability. With due attention to the Ural or another brand chainsaw, it is easier for the employee himself to cope with a well-tuned tool. The presented video helps to understand the principle of handling the mechanism.

Chain lubrication mechanism

For stable operation, the chain must be lubricated with oil. This role is played by a special unit. the lubrication mechanism. During operation, interruptions in its work may occur:

  • lack of oil in the tank, as a result of which a small amount of lubricant will flow to the chain. it is necessary to replenish the oil level;
  • clogging of the outlet channels. it is required to clean and replace the filter;
  • small diameter of the outlet opening is adjusted with a special screw.

During normal operation of the chain lubrication system, traces of oil can be seen if you bring a working saw to a light, uncontaminated surface, for example, to a fresh cut of a tree (stump).

The amount of oil supplied to the chain depends on the operating conditions. With dense, sticky or damp wood, the oil consumption should be higher. Dry material will require less lubricating fluid.

Carburetor setting

The carburetor is one of the components that ensure the stable operation of the chainsaw. The speed of the speed set, the output power, the uniformity of cutting depends on it.

Adjustment of the unit comes down to setting the minimum and maximum revolutions of the internal combustion engine, as well as setting the idle speed. This is done independently or with the help of a professional master.

With a properly adjusted, clean carburetor, the engine will:

  • immobility of the chain in idle mode;
  • smooth and fast set of speed of the chainsaw engine;
  • during operation, the gasoline unit sounds like a 4-stroke engine.

Chainsaw design

The chainsaw consists of several large independent units.

  • The internal combustion engine is designed to generate mechanical energy that is used to drive the chain saw.
  • The gearbox transmits the torque from the engine to the cutting tool. It is a set of gears and countershafts.
  • The clutch is an intermediate link between the gearbox and the chain. It is used for short-term breaking of the chain “reducer. chain”. Keeps the chain saw motionless when idling. Interrupts or weakens the transmission torque in abnormal situations (for example, braking the saw to a complete stop), which allows the engine to run and not stall.
  • An automatic brake interrupts the operation of the chain when it breaks, rebounds from the tree being processed, or abnormal operating modes occur.
  • Bar. guide for chainsaw.
  • Chain tensioning mechanism.
  • Chain lubricator and other elements.

How to tension the chain on a Husqvarna chainsaw

All safety rules described for the model above are the same for Husqvarna (Husqvarna) saws. Do not tighten the chain with the saw engine running. It is allowed to start work only after a complete stop and cooling.

Chainsaws & Tools : How to Shorten the Chain on a Chainsaw

Before tensioning the chain on your Husqvarna chainsaw, check if additional tension is required. It should be noted that new saw chains require more frequent tensioning. From time to time, it stretches during operation, so this operation must be carried out before each use, if necessary. Otherwise, it will be necessary not only to replace the chain, but also the saw drive mechanisms.

The first step is to loosen the securing nuts located on the clutch cover. The next step is to turn the adjusting screw 45 degrees. If the chain on your Husqvarna chainsaw is overtightened, turn to the left (counterclockwise). In the opposite case, the screw turns to the right. If a single tightening is not enough, the operation must be repeated. At the end of the procedure, tighten the nuts on the protective cover using a combination wrench. They can also check the chain tension of the chainsaw by hooking it on the outer tooth and pulling the chain along the guide in the tire.

Bus length. Pay attention!

What not least catches the eye when choosing chainsaws is the size of the tires: it depends on them how large the size of the logs can be cut.

The length of the chainsaw bar is one of the most important parameters affecting the convenience, speed and safety of work. This characteristic must be consistent with the operating power of the chainsaw engine, which is why any serious manufacturer indicates the recommended tire length parameter in the technical data sheet of its products.

What is the risk of ill-considered use of tires that are too long or too short? You should start with the fact that you cannot categorically exceed the tire size recommended by the chainsaw manufacturer. The smaller size is reasonably acceptable, but also not recommended: there is a perception that a short chain provides less stress on the tool, but remember that this can cause serious damage to the saw headset. The permissible deviation range must be specified by the manufacturer in the technical documentation attached to the saw.

Long chainsaw bars provide greater comfort when working with large material, for example, for deep cuts in thick logs. However, the use of a long tire paired with a low-power unit will give one disappointment: the engine power will not be enough to rotate the crankshaft, which means that fast cutting will simply be impossible. The sawing process will be slow, the gas consumption will be increased, the engine will wear out instantly.

A shorter bar length with the right tool power will provide a high cutting speed and will be optimal for use in work with small trees or boards.

The length of the saw bar, as a rule, is indicated in inches by both foreign and domestic manufacturers. Tires are marked in 2-inch increments. Below is the equivalent in the metric system of lengths familiar to Russians:

Poorly fixed drive sprocket

Quite widespread is the variant when the leading sprocket is poorly fixed. It often detaches itself during operation. The solution to this problem is carried out as follows:

  • The protective cover of the engine and spark plugs are removed, after which the air filter is removed.
  • The next step is to remove the spark plug, which requires a special wrench.
  • A special plug allows you to fix the piston in the desired position.
  • The clutch plate is turned with a special key until the position of the piston, which should be located on top, is changed.

Then you can fix the sprocket in the correct position and solve the problem in question. The specified information indicates that such work is quite problematic, it is often carried out by organizations servicing chainsaws.

Step-by-step installation algorithm

Not all modern chainsaws are equipped with a setting wheel, which greatly simplifies the procedure for installing the saw blade. Systems with a setting wheel are generally a rarity among household chainsaws. Therefore, it is very important to know the technology and sequence of installing the chain on a chainsaw.

Key points to look out for:

  • Prepare a level surface on which you will assemble the chain and bar. This will minimize the chance of damage to the chainsaw or loss of small parts. A tire is laid out on the prepared surface and a parallel chain next to it.
  • Remove the sprocket protection, on modern chainsaws it is enough to unscrew the wing nut, on older models, you may need a spanner wrench of the appropriate size.
  • At the base of the guide bar, turn the idler sprocket all the way to the right. Only in this position is the chain installed.
  • Then the chain is successively placed link by link on the fixing groove on the guide rail. Install the chain from the top of the guide, gradually turn it so that the bar is always on top and the chain is on the bottom, this will allow it to always be taut and fit into the guide groove without problems. When doing this step, be sure to wear thick protective gloves, because your fingers will touch the cutting edge. Viewed from above, the cutter is always forward towards the end of the guide bar.
  • Put both the tire and the chain on the drive sprocket.
  • Secure the chain sprocket cover in place. Make sure all mounting pins line up with the holes. Incorrect installation with distortions or not completely can cause extraneous noise, rattling.
  • Make sure that the guides “go” into the special mounting chute.
  • After installation, check that the chain is secure on the chainsaw and on the bar. Everything must be securely fastened without backlash.
READ  How to Adjust the Oil Flow on a Chainsaw

An important point is the degree of tension on the chain after installation. Setting the correct tension is easy and takes less than three minutes. First you need to loosen the nuts on the protective cover. Using the freely rotating adjusting screw, catch the correct tension so that the chain does not pull away from the edge of the guide bar more than 3-5 mm.

It remains only to tighten the nuts and check the tension. If correction is needed, adjust the tension again.

What is important to know: when the chain is in operation, due to frictional forces, its metal heats up and expands, and the length increases. Therefore, it is important to regularly check the tension and correct it in time.

How to install the bar and chain on the chainsaw, see the following video, which presents a clear algorithm of actions:

Keyless tensioning system

It began to be used relatively recently, it is considered new, if not advanced. Differs from the classic nut, as follows:

DON’T TOSS Your Chainsaw Chain TILL YOU WATCH THIS VIDEO!

  • another tensioner mechanism;
  • lack of an external tightening nut;
  • adjustment without additional tools.

Instead of a turnkey nut for 13 on the lid, there is a wing (rotary cap) with a handle for tightening by hand. It also has a nut, but it is hidden inside. Instead of an adjusting screw for a screwdriver in this system, the tension is carried out using the tension wheel (adjusting knob).

Instead of a gear shaft, there is a sprocket and a tension washer.

This system also has disadvantages:

  • the mechanism itself is more complicated than a traditional wrench;
  • the installation of the cutting attachment causes additional problems, since complicates the process of pairing all the parts in the right order;
  • less adjustment stroke, a slightly stretched chain will still serve with a traditional tensioning system, here it will sag and become unusable.

How should the chain be tensioned on a chainsaw?

The rule for how the chain should be tensioned is: the chain should move freely along the tire, but not sag. A little more, a little less. it doesn’t matter. The main thing is to walk freely and not sag. over, if you pull the chains from the tire, grabbing it in the middle of the tire, it should reach the height of the links entering the tire.

During operation, make sure that the chain does not sag. If you notice any slack, tighten immediately. And after work, it is better to loosen the chain. This must be done due to the fact that the chain heats up during operation and stretches (including because of this it has to be tightened), and then, cooling down, shrinks. As a result, it can break itself, and spoil the tire, and take away the shaft bearing on which the drive sprocket is held.

Here are all the rules for tightening the chain on a chainsaw. Thanks for attention!

I partially disassembled the chainsaw (for cleaning and assessing the condition of the parts). I also replaced the spark plug tip (it was all cracked) and installed an ignition switch (it was absent at the time of purchase of the saw). These details, as you understand, are not original :-))). And one more disadvantage is this. there is no oil reservoir cover. (Everything is indicated by arrows in the photo).

How to properly put the chain on a chainsaw video

How to tension the chain?

To properly tension the chain on a Husqvarna chainsaw with the engine not started, first loosen the screws securing the cover. After that, the part that corrects the tension is rotated. If the links sag from the bottom (even a little), then you need to tighten them. Before tightening the chain on a chainsaw (Husqvarna, for example), it is worth reading the attached documents. After all, the mechanisms of different firms have their own differences.

How should the chain be tensioned on a chainsaw? This can be determined by lifting it up. Normally, the shank should be one third immersed in the groove. If it came out completely, then the chain must be tightened, if it came out less than 2-thirds. loosen. When scrolling, the links must pass freely along the tire. After movement by hand, the links pass a little more by inertia under normal tension. If the chain instantly slows down, then this indicates a tug.

To quickly tighten the chain on a Stihl chainsaw, there are special devices that help you do this without keys. To use them, it is enough to release the sprocket cover, and then turn the adjusting wheel to the left to loosen, to the right to tighten. All this is only done when the links are cold.
